00:00<cmorgan>Chutt: i was going to add if(bitrate>maxbitrate) bitrate = maxbitrate; to avoid giving the driver invalid parameters
00:00<mdz>heh, there sure are a lot of places to change to add a column to the channel table
00:00<cmorgan>additional error checking is something else we should be doing

00:04<mdz>the error handling in xmlparse.cpp seems a little severe
00:04+sweetboy [] joined #mythtv
00:07zzz-sbh-zzzis now known as sbh
00:09+virsys [] joined #mythtv
00:10<mdz>it seems like some of those exit(0)s could be 'return's
00:10<Chutt>can't load the file, death
00:10<mdz>missing attribute on an xml element, kill the program
00:10<Chutt>though, it means that it's an invalid theme file
00:11<mdz>there are 86 of those tests
00:11<thor_>most of the modules are willing to live with things that are supposed to be in the theme but aren't
00:12<thor_>(not all, but many)
00:16<thor_>heh, g++ really dislikes stray ]'s in header files
00:18<mdz>gcc's whole behaviour of continuing after an error is questionable in my opinion
00:19cmorganis now known as cmorgan_zzz
00:21<Chutt>tmk, still here?
00:25<Chutt>david engel wanted me to ask you about your cvs tree and if you wanted to keep hosting it at sf :p
00:25<tmk>yeah i do
00:25<tmk>looks like it's stuck in select/sleep/ioctl
00:26<tmk>when it refuses to playback
00:26<Chutt>where in the code?
00:26<Chutt>he was just worried about keeping stuff current, since anon cvs is a little behind your stuff
00:27<tmk>i update cvs-latest when important
00:29<Chutt>ya ya
00:30<Chutt>just wanted to ask, that's all
00:43<FryGuy>chutt: should I have carried over the deadlock stuff i wrote to MpegRecorder too? I didn't really look into those too much because I didn't think they would have the same kind of problems.

01:00<Desiac>tv_grab_au has been shutdown, on the mailing list i found a working channel table so i've manually inserted it into the channel table, when i try and run mythfilldatabase i get the error cant find /.mythtv/.xmltv
01:01<thor_>hmmm mdz is being rather diligent
01:02<mdz>that's a nice way of saying "anal"
01:02<Chutt>what the hell is going on
01:02<Chutt>did that latest filter patch just fuck everything up?
01:02<mdz>mine? or was there another filter patch?
01:02<Chutt>not yours
01:02<Chutt>something i committed earlier
01:03<thor_>not up to current
01:04<mdz>basic playback is working OK here with cvs; what's busted?
01:04<thor_>USING_XV stuff?
01:04<Chutt>analog live tv
01:05<Chutt>regular playback
01:07<Chutt>i need a new kernel
01:07<Chutt>interactive performance while compiling sucks ass.
01:08<thor_>bigger desk, more 'puters
01:08<Chutt>naw, i retired all my machines :p

01:22<aceat64>can someone tell me what the difference is between the Gentoo packages MythTV and mythfrontend?
01:24<ahbritto>aceat64: mythfrontend removes some files after building: like mythsetup , if you are not recording on the machine, you can use mythfrontend
01:25<aceat64>so if I am recording all I need is MythTV?
01:25<aceat64>thank you

01:42<mdz>Chutt: do you have any feeling on <cfoo> vs. <foo.h>?
01:42<mdz>I noticed recently that <cfoo> is sometimes different from <foo.h> and have started using those more often
01:43<Chutt>eh, not really
01:46<Chutt>don't care one way or the other, aside that more people would be used to seeing the traditional includes
01:51<mdz>for instance, <cmath> declares overloaded versions of stuff for float vs. double so you don't need to worry about fabs vs. abs, etc.
01:55<Chutt>fuckin hell
01:55<Chutt>it was the win32 patch
01:56<Chutt>the guy didn't change all the videooutput classes
01:56<mdz>there's a win32 patch?
01:56<Chutt>well, cygwin
01:57<Chutt>i applied all the little things from it
01:57<mdz>even so, I didn't realize
01:57<mdz>what parts does it actually build?
01:57<Chutt>left out a few bits
01:57<Chutt>the frontend
01:57<mdz>does it have a video output class that works?
01:57<mdz>and audio?
01:58<Chutt>patch was on the -dev list today
01:59<Chutt>i haven't done a commit yet, though
01:59<mdz>I must have missed it

10:25<warlord>Uh, I think you just need to run "dvdauthor foo.mpg"...
10:25<warlord>or something like that..
10:26<warlord>I may have written a short script..
10:26<warlord>yea, it's like:
10:26<warlord>dvdauthor -o dvd goo.mpg
10:26<warlord>dvdauthor -T -o dvd
10:26<warlord>mkisofs -dvd-video -udf dvd.iso dvd

10:29<krash314>warlord: what kind of horsepower is needed to run dvdauthor?
10:30<warlord>no clue.
10:30<warlord>note that it doesn't have to run it real-time..
10:30<krash314>how long does it take to run thru the steps for u?
10:31<warlord>Didn't time it. Sorry.
10:31<krash314>guesstimate? :)
10:31<warlord>majority of the time was the dvdrecord
10:32<krash314>just wondering if I can get away with running this on my low end myth box PII-300
10:32<warlord>why not? so long as you're not encoding TV on it simultaneously.
10:33<krash314>well I will definitely give it a shot.
10:35<krash314>also wondering if I can just do the last 2 steps with a ripped vob file
10:36<krash314>most of this is pretty new to me, obviously
10:40<warlord>I'd suggest some web-reading...
10:40<krash314>and thanks

14:29<dunc>is there anything i can tweak to get more audio buffers? (something in /proc perhaps?)

14:57<Chutt>lmatter, how goes minimyth?
14:57<lmatter>slowly, life sucks up all my time.
14:58<lmatter>I'm using GAR to build it all from scratch. I'm using Ivor's open source MPEG driver now. Works nicely.
14:58<Chutt>that's cool.
14:59<lmatter>Stupid question if I may. You mentioned on mythtv-users that the nvideo RENDER accel option helps with alpha blending.
14:59<lmatter>Is there an equiv for CLE266? Is it just DRI?
14:59<Chutt>not that i'm aware of
15:00<Chutt>Qt uses the render extension to alpha blend pixmaps together, like in most of the mythtv UI
15:00<Chutt>the software blending is pretty damn slow, so unless the driver does some hardware render accel...
15:01<lmatter>ok thanks.

15:01<lmatter>You thinking 0.14 will be out in a week or so?

15:03<Chutt>hopefully the knoppmyth guys will manage to as well
15:03<kvandivo>they up to .12 yet?
15:04<Chutt>they're on 0.12

15:17+o_cee [] joined #mythtv
15:18<bdale>I'm trying to figure out how to get 1280x720 ... appears Xfree86 doesn't have a mode for it. Anyone have a working mode line I could try, or a pointer to where to find one? Been a long time since I crafted an X mode line from scratch...
15:18<o_cee>search gogle for xfree modeline generator
15:19<bdale>o_cee: cool. thanks. did a lot of searching last night, didn't find this though...
15:19<kvandivo>wow.. you actually can go to and do your searching..
15:19<o_cee>yeah :) i always do that
15:19<o_cee>faster to write ;)
15:23+sweetboy [] joined #mythtv
15:28<steelep>you still here?
15:35<steelep>this one works on mine, but has a pretty big overscan

15:35<steelep>that's on an ATI btw
15:45<Chutt>o_cee, i'm going to get gant into cvs this weekend
15:45<Chutt>so if you have any updates... =)
15:46<o_cee>i just send you an email :) (without update tho)
15:46<o_cee>is it possible to get write access to that dir?
15:46<Chutt>we'll see
15:46<o_cee>allright.. i guess i could send you the stuff i have at the moment and fix it up afterwards
15:47<o_cee>i moved the stuff over to the frontend, and the mythmusic stuff stopped working.. need to check that.. and there's some images that needs some size tweaking
15:48<o_cee>but i added the search title and the container david pointed out
15:50<bdale>steelep: thanks, my son is watching "between the lions" recordings from last week right now, but I'll try it later. I've got both a recent ATI and a recent nVidia card to play with...
15:52<bdale>another question... I'd like to optimally drive my 16x9 720p display, *and* get a 4x3 NTSC output to drive the modulator feeding other TVs around the house. Possible to do in a single frontend box showing the same program on both outputs simultaneously, or does this sound like a clear case of wanting a second frontend to get it all to work?
15:59*o_cee is away: Gone

16:11niqo_is now known as Niqo
16:15<hadees>how is native alsa support?
16:16<hadees>is it good enough so that if i want to use alsa i should use native alsa support instead of oss emulation in alsa
16:16<steelep>bdale, I'd use 2 frontends to drive one at 4x3 and another at 16x9
16:18<steelep>you could of course retransmit the 16x9, but what if you have 4x3 inside 16x9, then you retransmit that into 4x3, yuk.
16:19<steelep>if you want a rediculously cheap frontend, get an xbox
16:19<hadees>can the xboxs be used now with out a modchip?
16:19<hadees>i heard that someplace
16:22<steelep>not sure... try here
16:28<steelep>you can do a software hack to avoid modchips
16:30<bdale>steelep: yeah, pretty much what I figured. I've got lots of hardware to choose from, no worries there. Just realized late last night that if I cut the video on the main frontend over to optimally drive my uber-cool new widescreen in the living room, that I'm going to lose the NTSC feed for the modulator, and that will annoy the family. It's always something...
16:30<knight->are we talking about xbox linux?
16:31<bdale>so, why so much excitement about the xbox? the last time I looked, they didn't feel all that cheap. maybe I missed something?

16:32<bdale>who has them for that price? I'm not a game console fan-boy, so wouldn't know offhand where to shop.
16:33<kvandivo>gamespot has used ones for that.. or is it gamestop.. the one that's the store..
16:33+servo [] joined #mythtv
16:33<servo>ok so for the database; what username / pass am I suppose to give mythtv?

16:34<servo>mythtv as the username? and pass?
16:34<sfr>servo: yup
16:34<pahli_bar>knight-: shoot.
16:35<servo>oh ok =-) talk about security! heh
16:35<servo>I doubt anybody will try to use mythtv as a username on the server; lol ;-)
16:35<knight->pahli_bar, just trying to get my feet wetter in Qt for myth stuff... i created a simple app but it doesnt seem to work
16:35<knight->pahli_bar, it's segment faulting, and i'm not sure why...
16:36<pahli_bar>knight-: tarball?
16:36<sfr>servo: that's the login info for the mysql database. what you choose for the user running the backend/frontend is up to you.

16:41<bdale>knight-: thanks for the pointers. looks interesting, but as I already have a nehemiah itx board in hand, I'll probably just use that instead of having to hack on yet another platform.
16:41<knight->bdale, indeed
16:42<knight->bdale, i made a cluster of xboxs :)
16:42<pahli_bar>knight-: you need to have an the app running. right now in the main its just creating the class and exiting. you would need to do something like QApplication a(argc,argv); a.exec();
16:43<bdale>knight-: cool
16:43<knight->pahli_bar, even though i wont have anything in that app?
16:44<pahli_bar>hang on

17:15<kvandivo>i'd say, almost certainly, that there is a reason behind it
17:16<Chutt>The software which is used with OpenPVS is all free software. In the next few days (1 end of the month) you aim toward release, presently do ardent development. As for the software package it is the schedule which distributes on this sight.
17:16<Chutt>babelfish is funny
17:17<o_cee>cool :)
17:18<o_cee>hey, there's gant as well, hehhe

17:56<pahli_bar>what does ! in a diff mean
17:56<queuetue>Hi, all. Sorry if I sound stupid, newbie to video, but not to linux. This may be the wrong channel, but I was looking for information on controlling a directv box via linux IR for automatic recording via a tv-in card, for time-shifting purposes. Is there anything turnkey, or maybe some documentation that would get me started?
17:56<kvandivo>that it's a really important line
17:57<hadees>queuete: look at
17:58<hadees>queuetue: look at
17:58<queuetue>hadees: Does it do all of that (the IR control part?)
17:58<hadees>with lirc yes
17:58<hadees>you need to buy/make an IR reciver
17:58<queuetue>Awesome. I'd be better off buying one - where coudl I get one?
17:59<hadees>i like IRman my self
17:59<kvandivo>how much are you willing to pay?
17:59<queuetue>kvandivo: Uhm ... 20 bucks? :) I have no idea how much they are - hopefully not hundreds...
17:59<hadees>queuetue: it depends on your needs, you can get a pvr250 with a build in IR transceiver
18:00<queuetue>hadees: That sounds perfect - I need the pvr, as well.
18:00<pahli_bar>kvandivo: very funny !
18:00<hadees>queuetue: well on ebay you can get that card for around $100
18:00<sfr>hadees: the pvr250 one is a transceiver?
18:01<hadees>oh wait not it isn't
18:01*thor_ has bogged down everything with superfluous details .... MUWAHHHAAAHAA
18:01<hadees>sorry you need a reciver and a transceiver
18:01<kvandivo>why do you need two receivers?
18:02<queuetue>Hrm. Ok, stop and start again. What do I need? :)
18:02<hadees>kvandivo: you don't but usally don't you want to put the trans next to the directtv box in this case
18:02<hadees>you need to learn about mythtv
18:02<kvandivo>ya.. i need to install that at some point..
18:02<hadees>and make your own mind, you can get help in here, at
18:02<hadees>for the mailing list
18:03<hadees>and at the linux htpc message board on
18:03<hadees>also at
18:03<hadees>you also have to decide usally if your going to go with hardware encoding or software encoding
18:04<hadees>for recording tv that is
18:04<queuetue>hadees: Definitely hardwar encoding - the box is relatively weak.
18:04<kvandivo>wise choice
18:04<hadees>then you need more HD space
18:04<hadees>and you need a hardware card
18:04<pahli_bar>avermedia M179/M150 are only around 80$ at newegg
18:04<thor_>and a quarterback
18:05<hadees>i got mine for $50 on ebay
18:05<queuetue>Yup, froogle return 80 bucks at newegg. :)
18:05<pahli_bar>hadees: yeah. but its not available anymore there
18:05<hadees>queutue: just a heads up, they have just been added to the ivtv driver (the driver used for mpeg 2 tv recorders)
18:06<hadees>so if you can afford it i would spend the extra money for a pvr250
18:06<hadees>but thats just me
18:06<hadees>i do own 2 m179
18:06<pahli_bar>whats the difference?
18:06<queuetue>hadees: The $ difference is less than 40 bucks?
18:07<hadees>well i don't know if it is true or not (because i haven't gotten it working yet) but the m179 are supposed to be alittle less quality
18:07<pahli_bar>some guy on the user ML said that there's no difference in quality between the two
18:07<queuetue>Yeah, it's 100 bucks at newegg (OEM version, but I can't use the softwar anyway)
18:08<kvandivo>i've got both.. haven't played with the 179 much yet, but haven't noticed any quality differences myself
18:08<queuetue>Oh, wait. refurb.
18:08<hadees>well also you end up using the pvr250 firmware on the m179 so hopfully there won't be future problems with that
18:09<pahli_bar>hadees: the chipset is the same. so firmware shouldn't matter
18:09<hadees>i thought the chipsets were just similar not the same
18:10<hadees>alright don't lisen to me then
18:10<queuetue>For 60 bucks, I think I'll chance the m179 - I'm not really that into quality issues. :)
18:11<kvandivo>i think you still have to patch ivtv to get m179.. so be prepared for an ever so slightly higher level of general linux awareness that will be needed
18:11<kvandivo>last i heard tmk hadn't merged 179 in yet
18:11<kvandivo>anyone that wants to can correct me, though
18:12<hadees>nope m179 still needs to be patched
18:12<queuetue>So, an m179, a big-old HD, and an irman? (is an irman a tranciever, or just a reciever?)
18:12<hadees>go to
18:12<hadees>they have a better list of that stuff
18:13<kvandivo>(and you can never have too big of a hard drive.. i'm currently at 280 gigs and am seriously thinking about grabbing one of those 200 giggers next time they have them for $100)..
18:13<pahli_bar>there is prepatched ivtv at the ivtv wiki website
18:13<sfr>$100 for 200gigs? live is not fair :(
18:14<kvandivo>i don't buy HD space anymore for more that 50 cents a gig..
18:14<queuetue>Wait ... Can I use the IR reciever on the hauppage card? So all I need is a transmitter in addition to a pvr250? Does the m179 have a reciever?
18:14<kvandivo>the problem i've had lately is finding drives large enough to make it worth the time (running into IDE bus limits, etc)
18:15<queuetue>Should I ask this in #lirc? :)
18:15<queuetue>No one in #lirc...
18:15<pahli_bar>m179 don't have a receiver

19:56<servo>sorry; come on. I'm new; give me a little bit of slack (lol). I'm learning at a slow pace, ok so it WAS in the manual. I don't always know weather I should search the forums or look at the manual or ask here. I'm only trying to enjoy my linux experiance. I can't go back to windows!
19:56<pahli_bar>Chutt: it would be nice if you set the topic to "Developers only channel. #mythtv-users for user questions"
19:57<Chutt>pahli_bar, the channels -t
19:57<Chutt>and i don't mind some user questions
19:57<Chutt>just moronic ones
19:57<servo>but then everybody in that channel woulnd't be able to help; they would just ask questions
19:57<Chutt>thor, so, yeah, looks like a problem in qt or the mysql client lib
19:57<pahli_bar>servo: wrong. there will be some developers there too.
19:58<thor_>I thought so
19:58<hadees>servo: fyi most stuff is answered in the docs, if it isn't in the docs search the mailing list archives if it isn't in there then ask in here
19:58<pahli_bar>servo: and there are advanced users too
19:58<thor_>I'll try it on another qt
19:58<Chutt>you're still using 3.2.0b1?
19:58<Chutt>that _may_ be it, but i dunno
19:58<thor_>on this here box, yup
20:00<hadees>question: do i need to enable Xv somewhere to get it working or is it supposed to autodetect?
20:00<LenoPock>well, don't forget the tragically helpless users like me. Now that mythtv is working for me, my bttv card outputs 0 audio, even from the line-out on the card
20:00<Chutt>hadees, it's part of x
20:01<pahli_bar>extmod to be specific
20:01<pahli_bar>Section "Module"
20:01<hadees>Chutt: i know it is thats why i don't understand why it isn't working
20:01<pahli_bar> Load "extmod"
20:01<LenoPock>hadees: xdpyinfo IIRC will show you if it is enabled for your server
20:01<lmatter>pahli_bar, are you an X-pert? I have a couple questions on optimizing X for mythfrontend.
20:02<pahli_bar>lmatter: nope. i'm not
20:02<lmatter>Well, I'll ask anyway, as they are pretty simple questions.
20:03<lmatter>Does double buffering help with mythfrontend? What about dri?
20:04<hadees>LenoPock: xvinfo returns no adaptors present
20:04<pahli_bar>lmatter: not sure about double buffering. dri will help in opengl based visualizations for mythmusic and mythgallery
20:04<lmatter>pahli_bar, thanks.
20:04<pahli_bar>lmatter: np
20:05<thor_>anyone have problems with Qt 3.3.0 beta?
20:05<pahli_bar>lmatter: render acceleration will be key optimization.
20:05<LenoPock>hadees: what x server display module are you using? (nv,vesa,ati)
20:06<hadees>LenoPock: Nvidia
20:06<lmatter>pahli_bar, I saw that nvidia has that. I need it for EPIA (CLE266)
20:06<Chutt>hadees, nothing in the server logs?
20:06<pahli_bar>lmatter: ah... i dunno about that. i don't epia has dri
20:07<pahli_bar>s/don't/don't think/
20:07<pahli_bar>i believe only matrox and nvidia have hardware render support
20:08<lmatter>pahli_bar, another simple question, dri == render support?
20:08<LenoPock>ati has full support with their binary drivers
20:08<pahli_bar>lmatter: dri != render. dri is related to opengl. render is related to fonts/alphablending
20:09<pahli_bar>LenoPock: really! that nice to know.
20:09<pahli_bar>LenoPock: how is their tv-out support?
20:10<hadees>Chutt: it says it loads XVideo (not sure if that is Xv) but it doesn't mention anything about Xv or any errors
20:10<LenoPock>pahli_bar: AFAIK pretty bad, but my card doesn't have tvout
20:11<pahli_bar>and the radeons are pretty expensive too.
20:12<pahli_bar>hmmm... maybe not.
20:13<LenoPock>pahli: with the old rage 128, if you booted with the tvout as the only thing plugged in, it would do tvout pretty well, with no config
20:13=lmatter [] quit ("Leaving")
20:14<pahli_bar>ah. the rage cards. pitiful video memory though
20:15<hadees>and Load "extmod" is in my XFree86 file
20:15<LenoPock>yah, but hey, I think they support Xv and Xrender

20:16<hadees>this doesn't have anything to do with my problem does it?
20:16<hadees>(WW) System lacks support for changing MTRRs

20:20<hadees>LenoPock: the thing that is throwing me for a loop is that i have had mythtv running before and i never heard of this error... i keep running into new errors
20:20<LenoPock>what kind of system is this?
20:20<pahli_bar>hadees: xvinfo show anything
20:21<hadees>pahli_bar: xvinfo returns no adaptors present
20:21<LenoPock>hadees: did xdpyinfo show anything?
20:22<pahli_bar>humph... did you look at /var/log/XFree86.0.log and see if it was able to load XVideo
20:22<hadees>pahli_bar: yeah it is loaded
20:22<hadees>LenoPock: xdpyinfo showed alot of stuff but nothing i saw that would help i don't think atleast
20:22<LenoPock>you aren't running at 8bpp, are you?
20:23<pahli_bar>hadees: tried a complete shutdown and boot? :)
20:23<LenoPock>does xdpyinfo show a module list?
20:25<hadees>LenoPock: yeah and Xvideo is loaded
20:25<hadees>i am going to try recompiling xfree
20:25<hadees>it is the last thing i can think of
20:26<hadees>mabey the computer got to hot or somthing
20:26<hadees>while compiling somthing
20:26*pahli_bar doesn't remember compiling xfree86 ever
20:26<LenoPock>eek. recompiling X will probably break more than it will fix
20:26<pahli_bar>oh wait. during those freebsd days...
20:27<hadees>LenoPock: i use gentoo so it should be fine
20:27<LenoPock>I used to compile X for stampede linux (bless it's soul)
20:27<hadees>everything on my system is compiled

20:37<pahli_bar>knight-: here.
20:38<knight->pahli_bar, any ideas why the op.copy() isn't copying the remote files to local?
20:39<drd->u know about functions but dont know whut it uses to do transparencies? :(
20:39<pahli_bar>knight-: i didn't look very carefully. couple of things i noticed though: 1) Qapplication needs to be running for the eventloop to run 2) you would need to initalize the network protocols
20:40<pahli_bar>drd-: what transparencies?
20:40<drd->in the 'watch recordings' and 'delete recordings'
20:40<Chutt>the x render extension
20:41<pahli_bar>ah. he meant alpha
20:41<drd->the extra set of bits that make somethin look transparent?
20:42<pahli_bar>drd-: as Chutt said the x render extension
20:43<drd->tyty too kind
20:44<Chutt>one thing you can do is run qtconfig and make sure that it's set to use xft for font drawing
20:44<Chutt>qt's render stuff is only turned on if xft is also turned on

21:55<Chutt>welcome back =)
21:55<Captain_Murdoch>didn't want you to think I'd dropped out of sight. :)

21:55<Chutt>i've told people to ask you stuff every now and then

21:56<Captain_Murdoch>I've replied to a couple private emails I think.

22:00<ElectricElf>Anybody know why MythTV needs /dev/dsp?
22:01<Niqo>it want to put sound there
22:01<Captain_Murdoch>to play sound?
22:01<ElectricElf>Ah, for things other than using a tuner, sure.
22:01<foucault_>it's for oss and/or ALSA OSS sound emulation
22:01<Chutt>got to record sound from somewhere, too
22:01<ElectricElf>foucault_: I know what it is. Just couldn't figure out why it's trying to open it.
22:01<ElectricElf>Segfaults shortly thereafter.
22:01<ElectricElf>(This being mythtv-backend)
22:01<ElectricElf>Still don't think it should be the one opening it.
22:02<Chutt>why not?
22:02<ElectricElf>Chutt: Why would it?
22:02<Chutt>to record stuff?
22:02<ElectricElf>Chutt: The frontend, sure. The backend?
22:02<ElectricElf>Chutt: Hmm, does it record everything you watch?
22:03<ElectricElf>Chutt: (Like, keep a buffer and such)
22:03<Chutt>of coures
22:03<ElectricElf>I seem to recall a knob for that...
22:03<ElectricElf>Chutt: That would explain it then.
22:05*ElectricElf loads btaudio and tries to get it to use those devices instead :)

22:09<ElectricElf>I had actually thought it used it for playing, but it was trying to *read* from the device. Never even crossed my mind it was trying to record when I was watching via the tuner.
22:09<Chutt>send a backtrace to the list =)
22:11<aceat64>gah, I'm so close to using my PVR-250, but once I get to insmod ivtv it freezes, I've tried 3 differenet kernels too
22:11<foucault>which ivtv version?
22:11<aceat64>latest one
22:11<Chutt>that's not an answer
22:12<Chutt>that could mean cvs-latest
22:12<Chutt>or 0.1.9

22:12<Chutt>top news item
22:12<foucault>don't use that
22:12<servo>whooot! Ok I got mythtv running backend and frontend. =-) tomorrow ill read the manual to figure out how to use this thing. It looks good so far! I like the TV Guide A LOT! lol its sooo cool!

22:44<foucault>Hauppauge pvr-350
22:45<foucault>you get mpeg-2 encoding and decoding all in one package
22:46<foucault>if you don't need to output to a TV (e.g. you'll be watching all your video on a monitor or a remote display), get a PVR-250.
22:46<foucault>same card, no mpeg2 decoding
22:51<aceat64>yay, it works, thanks guys
22:51<Niqo>crabchips: get a digital card if you have access to digital tv...
22:52<Niqo>or else what foucault said :)
22:54<aceat64>I can get HDTV in my house, does the WinTV-HD work with MythTV?
22:57<crabchips>how stable is the 350 at the moment?
22:58<cmorgan>appears to be pretty stable
22:58<cmorgan>no crashes in 3 hours now ;-) hehe
22:59<crabchips>haha .. really?
22:59<cmorgan>yeah, mythbackend crashed for some reason(running cvs so might be normal instability)
22:59<cmorgan>locked up when i paused it tonight as well
22:59<cmorgan>but who knows...
22:59<cmorgan>if it is running tomorrow i'll be happy
23:00<crabchips>think it's the 350 driver or myth?
23:00<Niqo>aceat64: pcHDTV (
23:00<foucault>fwiw, i'm running my 350 for encoding only (no tv-out) and have not had the driver crash in several weeks
23:01<cmorgan>yeah, there may be some issues with ivtv fb
23:01<foucault>some? that's generous ;)
23:01<aceat64>thanks Niqo
23:02<cmorgan>foucault: even ivtv from a month ago was up for a whole month recording
23:02<cmorgan>i'm hoping the crashes with tv-out are rare
23:04<crabchips>is it possible to play to tv out without effecting my monitor...
23:04<cmorgan>its a completely different output
23:04<crabchips>i mean, could my girlfriend watch tv and get the myth interface and i still use the computer?
23:04<cmorgan>and its hardware backed on the 350, so you probably won't even know you are doing so
23:04<cmorgan>that i'm not sure about... interfacing to myth would be tricky
23:04<cmorgan>maybe lirc would handle that though
23:05<crabchips>the infrared?
23:05<cmorgan>yeah, maybe the ir inputs from the remote will get passed to myth and your keyboard input won't
23:05<cmorgan>i'm suspect of that though ;-)
23:06<crabchips>i could run two instances of x
23:06<cmorgan>i'm not sure how the frontend handles that stuff... you could just start playback and background the window
23:08<foucault>here's one i haven't kicked yet: livetv is really, really slow in recent versions (since .13). the jitter reduction/experimental av sync code fix the problem, but at the expense of quality.
23:08<foucault>i have the bitrate for livetv set @ its lowest
23:08<foucault>and see this whether the frontend is local or remote to the backend
23:09<foucault>anything i can tweak to improve this?
23:09<Niqo>foucault: how does the jitter correction deter video quality?
23:10<foucault>the backend is running an athlon 2500+ and should be more than capable of decoding a single mpeg stream...
23:10<foucault>overclocked, even.
23:10<Niqo>still needs something to sync to, except usleep
23:10<foucault>niqo: without it turned on, i get a frame rate of btwn 2-4fps
23:12<foucault>with it on, i get a reasonable frame rate but highly pixelated video
23:12<crabchips>how much might i expect a good dedicated mythtv system to cost me?
23:13<Niqo>that would be a bug, yes, because the default would be to usleep for about the amount of delay between frames (iirc)
23:13=cmorgan [] quit (Remote closed the connection)
23:14<Niqo>the jitter reduction/exp av sync does not change the picture in any way, but it might be that your pvr 350 does something wired with a delayed frame
23:15<Niqo>crabchips: depends on what you need (like: how many concurrent recordings would you like, and how many frontends)?
23:16<foucault>ok, i take it back. it's the "extra audio buffering" that fixes it. just played with all of the settings and found that that's the one.
23:16<Niqo>make sure deinterlacing is turned off (dunno if it has an effect on the pvr350, anyone?)
23:16<crabchips>Niqo, jeez i don't know.. 2 concurrent recordings while watching another show??
23:17<crabchips>what do you mean by frontend?
23:17<foucault>it's off
23:17<crabchips>say, 1 tv playing show A, while show B and show C record in the background
23:18<Niqo>faucault: ok, with the extra audio buf. turned on causes pixelation?
23:19<Niqo>crabchip: do you have access to digital tv?
23:19<foucault>niqo: frame rate for live tv goes from 2-4fps to something much closer to NTSC but video quality is fair at best. Recorded shows with identical encoding settings playback perfectly.
23:20<crabchips>Niqo, i do but don't have a digital cable box
23:21<foucault>crabchips: your biggest expenses are likely going to be the tuner card(s) and hard drives.
23:22<Niqo>foucault: remember that livetv is a recording played back realtime
23:22<foucault>niqo: understood.
23:22<crabchips>well.. i'm just trying to justify the cost of a mythtv box versus a tivo
23:22<Chutt>foucault, harddrive dma turned on?
23:23<foucault>chutt: yes
23:23<Niqo>crabchips: what kind of digital tv? hdtv? digital satellite? directv? (if directv you would need one of those boxes for each card in your pc)
23:24<crabchips>Niqo, local cable? comcast digital
23:25<foucault>crabchips: tough to justify the cost. if you like to tinker and are generally at the leading edge of technology adoption, you won't find a better pvr than mythtv. if you want something cheap that just works and don't really care what's behind your TV watching experience, TiVo may be better for you.
23:26<Niqo>i'm unsure, but i suspect it has a proprietary box, so you would need either a pvr350 (which includes excelent tv out) or a pvr250 (recomended if you have this card in another computer than that is connected to the tv)
23:27<Niqo>is for other hardware, I would suggest something that is silent (if that matters for you) for a frontend; the via epia series is excelent
23:27<crabchips>hmmm.. are you saying the frontend just needs play back?
23:27<Niqo>the casing, memory and other gadgets is mostly up to you
23:28+tmk [] joined #mythtv
23:28<crabchips>i mean.. could i have one machine record the shows in the background (my main pc), then have another pc with tvout as the frontend?
23:28<foucault>crabchips: that's pretty much a fundamental capability of mythtv
23:28<Niqo>it could do both things (record and playback) but the recording (and livetv) would be limited to the number of capture cards you have
23:29<crabchips>so does the mythtv interface only runs on one machine?
23:30<crabchips>while another machine records in the background?
23:30<crabchips>sorry for all the questions.. i am confused :)
23:31<Niqo>np, there is the possibility of doing both on the same machine, but this would imply leaving this machine on about round the clock
23:32<foucault>there are two primary components to mythtv: the frontend and the backend. Backend does recording, frontend does playback (gross oversimplification). The frontend can run on the same machine as the backend, or you can put the frontend on other machine(s) network connected to the backend.
23:32<Niqo>btw: there has been some recent changes to cvs, which could make this machine turn itself on whenever there is a recording, dunno how well it works though
23:33<crabchips>does the backend run silently?
23:33<Niqo>Chutt: is a wiki (or alternativly a forum) on out of the question?
23:33<Chutt>i don't like either
23:34<foucault>funny, i was going to ask the same
23:34<foucault>about a wiki, anyway
23:34<Niqo>Chutt: the admin details of it all (or just the consept)?
23:34<Chutt>it's a bunch more work for me, yes
23:35<Chutt>and i really don't like the concept of a wiki
23:35<Chutt>and i just can't stand using a forums when a mailing list is available
23:35<Niqo>ok, so a forum might be considered as long as none of the admin work fell on yourself?
23:36<Chutt>no, not really
23:36<Niqo>i, myself, find a forum much easier to browse through postings and finding problems already solved
23:36<mdz>how is a forum better than a mailing list archive?
23:37<Chutt>the gossamer threads stuff does pretty good for that
23:37<thor_>in fact, you could search it for the numerous times this debate has come up
23:37<Niqo>i know, so i should shut up

23:49<tmk>with one button
23:49<Niqo>ah, boring then :)
23:50<tmk>and is there any reason that 3x ff is the fastest david's patch lets you go?

23:51<ofer>never mind, its working
23:51<ofer>thank you folks =)
23:51<ofer>awsome program =)
23:52<Niqo>i wanted a major story about the name, hehe, at least a quote like 'What I really want is the convergence device that has been talked about for a while' (btw: it's many years since that first got focus on
23:52<Netslayer>i'm trying to extract mp3 audio from mpeg4 with out much luck, tried tcextract but the file is unreadable, any ideas? how about mythtranscode?
23:52<ofer>im hoping to help by writing a frontend for winblows using the dsmyth directshow driverss
23:53<ofer>whoa, neato
23:53<ofer>ill try that too =)
23:53<Netslayer>how does the time scheme work with mythtranscode i can't get it to find my file, i've tried every kind of start time and it doesn't like it
23:54<Niqo>tmk: no, the max ff rate should be a user choice...
23:54<tmk>is it in the settings somewhere?
23:54*tmk looks
23:57*Niqo looked too; but could not wrap tv_play.cpp at the moment
23:58<Niqo>ahh, SSPEED_MAX
23:59<Niqo>16x seems like the max from it's table...
