| 06:54 | <stuarta> | so there is some info on the freesat epg broadcast |
| 06:54 | <stuarta> | http://www.digitalspy.co.uk/forums/showthread.php?s=9062c72f3d282ed5b2dc498ff990a8ce&t=751053 |
| 06:55 | <stuarta> | it is however 2003, so it is probably out of date |
| 06:55 | <stuarta> | ignore me, it's from feb 2008 |
| 06:59 | -!- | MavT [n=Maverick@111.86.233.220.exetel.com.au] has joined #mythtv |
| 06:59 | <gbee> | I was going to say, freesat probably wasn't even a gleam in the milkmans eye back in 2003 :) |
| 07:00 | <stuarta> | ondigital? |
| 07:00 | <stuarta> | err |
| 07:00 | <stuarta> | not free, not sat |
| 07:00 | <stuarta> | doh |
| 07:00 | * | stuarta goes looking for his brain |
| 07:03 | <janneg> | do they use the same description over DVB-S as over DVB-T? |
| 07:03 | <stuarta> | no idea, not seen the raw data yet |
| 07:03 | <stuarta> | apparently it's zlib compressed to |
| 07:03 | <stuarta> | o |
| 07:04 | <janneg> | that won't help, it's compressed |
| 07:04 | <clever> | cant just decompress it on the fly? |
| 07:04 | <stuarta> | of course, we just haven't done any coding for it |
| 07:04 | <janneg> | and it is not zlib |
| 07:05 | <stuarta> | i might just order a card |
| 07:05 | <janneg> | at least according to the guy why who tried to decode it |
| 07:05 | <stuarta> | find out meeself |
| 07:06 | <gbee> | wish there was a more concrete timeline on when it might switch to DVB-S2 |
| 07:06 | <janneg> | we're suspecting a similar appraoch as used in ATSC but with different Huffman tables |
| 07:06 | <stuarta> | wouldn't surprise me |
| 07:10 | -!- | famicom [i=famicom@c51447ddc.cable.wanadoo.nl] has joined #mythtv |
| 07:10 | <zaheerm> | i have almost cracked their compression |
| 07:10 | <zaheerm> | and it is not zlib compressed |
| 07:10 | <gbee> | stuarta: btw, justinh was suggesting that a few people might want to split the cost of one of these and then send it to mkrufky - http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=808585 |
| 07:11 | <gbee> | unless janneg wants to work on a driver? :) |
| 07:11 | <zaheerm> | there are 2 codebooks |
| 07:11 | <zaheerm> | and yes similar to atsc, just different tables |
| 07:12 | <stuarta> | now that is a card |
| 07:12 | <zaheerm> | wow, yes get a driver done and i'll buy one :) |
| 07:12 | <gbee> | I especially love the price |
| 07:12 | <zaheerm> | only 31 GBP |
| 07:12 | <stuarta> | only dvb-s |
| 07:12 | <clever> | and look at the pcie connector |
| 07:12 | <clever> | so damn short:P |
| 07:12 | <zaheerm> | wonder if it allows operation of dvb-s and dvb-t at same time |
| 07:13 | <stuarta> | so bits of it may already work |
| 07:13 | <zaheerm> | problem is it is full height |
| 07:13 | <clever> | yeah wont fit a tiny box |
| 07:13 | <gbee> | bigger problem right now is that it's PCI-E |
| 07:13 | <zaheerm> | not a bigger problem |
| 07:13 | <clever> | i have no pcie motherboards |
| 07:13 | <zaheerm> | has higher bandwidth |
| 07:13 | <clever> | just a mini-pcie laptop |
| 07:14 | <zaheerm> | so more possible to send full multiple transport streams |
| 07:14 | <clever> | record 32 channels at once?:P |
| 07:14 | <gbee> | zaheerm: bigger problem because of the linux support, means longer to a working driver |
| 07:14 | <janneg> | gbee: If I have access to a dish I'll by that card |
| 07:15 | <zaheerm> | janneg, i could buy a card, put it in a machine that you can have full access to if you want :) |
| 07:15 | * | stuarta goes for lunch |
| 07:16 | -!- | MaverickTech [n=Maverick@111.86.233.220.exetel.com.au] has quit [Connection timed out] |
| 07:16 | <janneg> | zaheerm: that wouldn't help much. writing pci drivers without specs and direct hardware access is almost impossible |
| 07:17 | <clever> | janneg: why you need direct hardware access? |
| 07:17 | <clever> | a few hi res scans would get you all the part numbers |
| 07:17 | <clever> | enless you want to start scoping out pins it should be 80% of what you need |
| 07:17 | <janneg> | and the motivation to get the card working isn't that high if one wouldn't use it for oneself |
| 07:18 | <clever> | yeah thats another thing |
| 07:18 | <clever> | and then theres the times you hardlock the box:P |
| 07:18 | <clever> | cant kick the power button |
| 07:18 | <janneg> | clever: reseting the machine after lookups, serial console, ... |
| 07:18 | <clever> | ive got serial console on my master server |
| 07:18 | <clever> | piping into putty on an xp box |
| 07:18 | <zaheerm> | janneg, i can buy you one for yourself too, just connect one here to a satellite so you can start working on it before you get a dish to connect your one to...can also provide you a serial console also |
| 07:19 | <clever> | but ive yet to find out how to hit sysrq over serial |
| 07:19 | <clever> | so i cant sysrq reboot it |
| 07:19 | <clever> | and sometimes even sysrq doesnt work |
| 07:19 | <janneg> | clever: sysrq works over serial |
| 07:19 | <clever> | yeah using the 'break' key |
| 07:19 | <clever> | but ive yet to get that to actualy work |
| 07:20 | <janneg> | zaheerm: I have first to find a flat where I can install a dish |
| 07:21 | <janneg> | and it would take time to get the driver working |
| 07:21 | <clever> | ive got a dish on my roof(it came with the house) but ive yet to get a card to see what i can pick up legaly |
| 07:21 | <clever> | (for free) |
| 07:44 | <Dibblah> | The drivers for that card are already being developed. |
| 07:44 | <Dibblah> | Last progress report was before christmas, from Manu. |
| 07:45 | <Dibblah> | Basically, "there have been some communications problems regarding NDAs etc, but they should be getting resolved soon" |
| 07:47 | <janneg> | Dibblah: that's just the driver for the nxp bridge or for that card specially? |
| 07:48 | <Dibblah> | Bridge chip, AFAIK. |
| 07:48 | <Dibblah> | However, compared to that, tuners are easy :( |
| 07:55 | -!- | TelnetManta [n=benwilli@72.159.132.4] has joined #mythtv |
| 08:06 | <janneg> | and the tuners/demods are worked on too, TDA10046A/ZL10037 |

| 08:12 | <gbee> | Dibblah: went with that Satelco card |
| 08:12 | <Dibblah> | Delivery times are usually quite good with dvbshop |
| 08:14 | <stuarta> | like if i ordered today, i'd get by friday? |
| 08:15 | <Dibblah> | Quite possibly. |
| 08:15 | <Dibblah> | Anyone looked in any depth at pulseaudio? |
| 08:15 | <stuarta> | hmmm, not worth risking. home this week, office next week |
| 08:16 | <Dibblah> | It's an audio server with some interesting features. Automatic upmix / downmix (dumb, but still), network capable,... |
| 08:18 | <gbee> | I'd rather invest time in OSS4 - has all those capabilities built in |
| 08:19 | <Dibblah> | Argh. Backed the wrong horse again :( |
| 08:20 | <gbee> | well actually I don't know about networking, but I wouldn't be suprised |

| 08:45 | <MrGandalf> | what's so great about OSS4 anyways? |
| 08:46 | -!- | joobie [n=joobie@joobie.org] has quit [Client Quit] |
| 08:48 | <gbee> | nicer API, easier end-user setup, better sound quality and upmixing etc |
| 08:49 | <gbee> | portable too, which alsa isn't |
| 08:50 | <MrGandalf> | I see |
| 08:50 | <MrGandalf> | isn't it lacking in features compared to alsa though? |
| 08:51 | <gbee> | no, more features or at least equivalent, but it does have fewer drivers than Alsa |
| 08:51 | <Dibblah> | And it appears to have proper enumeration for apps. |
| 08:52 | <MrGandalf> | ok |
| 08:52 | <Dibblah> | ie an app can get a list of soundcards. |
| 08:52 | <Dibblah> | Which is something not so user-friendly with ALSA. |
| 08:54 | <gbee> | it can get the cards, along with user friendly names etc (instead of Alsa's plugiec958:1,3 stuff) |
| 08:54 | <GreyFoxx> | You can likely get a prepackaged one if you don't need anything bleeding edge |
| 08:54 | <GreyFoxx> | oops |
| 08:55 | <gbee> | http://manuals.opensound.com/developer/device_discovery.html |
| 08:55 | <gbee> | http://manuals.opensound.com/developer/ |
| 08:55 | <GreyFoxx> | is oss4 expected to replace alsa "officially" or is it just a competing driverset ? |
| 08:56 | <gbee> | GreyFoxx: right now it's not GPL'd, but they are considering that and then pushing to get drivers into the kernel |
| 08:57 | <gbee> | there is no official movement to get OSS in as an Alsa replacement, but there is a fair bit of outside pressure because everyone is sick of Alsa |

| 11:09 | <gbee> | cool, disabling the deblocking brings CPU usage down to 60% on each core and removes the last trace of prebuffering pauses |
| 11:10 | <GreyFoxx> | any image quality problems from it ? |
| 11:10 | <janneg> | gbee: do you notice visual differences? |
| 11:28 | <gbee> | janneg: no |
| 11:29 | <gbee> | which doesn't mean an videophile won't spot some difference, but it looked identical to me |
| 11:29 | <gbee> | s/an/a/ |
| 11:29 | <gbee> | it dropped total cpu usage from 150% to 120% |
| 11:30 | <gbee> | even with deinterlacing re-enabled that allows perfect playback on that machine |
| 11:31 | <gbee> | I managed to improve things by fine tuning the optimisations, but of all the changes I made turning off deblocking had the biggest impact on processor usage |
| 11:32 | <gbee> | when the dvb-s card arrives and I've got more samples to play with I'll let you know if it affects the playback of other streams |
| 11:34 | <zaheerm> | what channel are you trying to play? |
| 11:35 | <janneg> | I can't spot visual differences either with in loop deblocking disabled |

| 11:35 | <zaheerm> | aaah ok |
| 11:35 | <stuarta> | sadly no longer broadcasting on dvb-t |

| 12:31 | <janneg> | gbee: probably, but try to avoid adding options |
| 12:34 | <janneg> | I try ... |
| 12:35 | <gbee> | well I'm not sure of the best way to do that, we could disable it entirely and see if anyone complains about decrease quality |
| 12:35 | <gbee> | or we could make it complicated and decide to enable it based on the machines speed and number of cores available |
| 12:41 | <janneg> | or we could enable it by default and add a hidden setting |
| 12:41 | <janneg> | i.e. a database setting without ui |
| 12:44 | <gbee> | given the performance boost and lack of side-effects I'd suggest it was disabled, users might just assume their CPUs are too slow and buy new ones, but if the image quality was poor they'd probably look for other causes and discover the hidden setting |
| 12:44 | <gbee> | disabling it will give more users access to h.264 content |
| 12:44 | <gbee> | IMHO |
| 12:48 | <janneg> | I'm not sure but for HD it is imho overkill |
| 12:50 | <sphery> | wonder if it could be part of the playback profile... |

| 14:31 | <Dibblah> | Search for skiploopfilter in http://www.mplayerhq.hu/DOCS/man/en/mplayer.1.html#DECODING/FILTERING%20OPTIONS |
| 14:33 | <gbee> | Dibblah: I'll play with different values |
| 14:33 | <Dibblah> | The issue is, if you never do deblocking, there is no reference frame ever. |
| 14:34 | <Dibblah> | (even keyframes need deblocking to become a reference frame) |
| 14:34 | <gbee> | it even states there that it's not really required for HD, so if it's part of the playback profiles it could be enabled for SD and disabled by default for HD |
| 14:34 | <gbee> | or at least operate at a lower level for HD |
| 14:35 | <Dibblah> | So the divergence between the intended picture and the displayed picture grows over the life of the decoder. |
| 14:35 | <Dibblah> | (deblocking is a 3d process, as far as I understand it) |
| 14:36 | <gbee> | I'm not going to pretend I understand what it's actually doing, but I get what you are saying |
| 14:36 | <gbee> | nonkey might be enough for HD? |
| 14:37 | <danielk22> | deblocking can be very useful for HD. It's what allows MPEG-4 at 15Mbps to look as good as MPEG-2 at 19Mbps. |

| 14:38 | <danielk22> | It gets rid of those terrible 16x16 or 8x8 blocking artifacts.. |
| 14:38 | <Dibblah> | There's some other pages that mention it as well. But yes, from my understanding, nonkey reduces most of the processing impact while still providing a non-degrading decoder. |
| 14:39 | <gbee> | a 30% reduction in cpu without deblocking and no apparent degradtion in picture quality for higher bitrate HD is not something I feel we can ignore |
| 14:40 | <Dibblah> | Indeed - But how long did you watch for? |
| 14:40 | <gbee> | the length of the sample which is only about 5 minutes admittedly |
| 14:41 | <Dibblah> | Should be sufficient. |
| 14:41 | <Dibblah> | It's only an issue on things with low-motion. |
| 14:41 | <Dibblah> | (talking heads, etc) |
| 14:41 | <danielk22> | gbee: I think we should have an option somewhere to disable deblocking for slow CPU's, just like we have the onefield deinterlacer for CPU's that can't handle HD deinterlacing. |
| 14:42 | <gbee> | danielk22: the patch I mentioned earlier, attached to #4653 does just that |
| 14:42 | * | Dibblah hates the idea of more options, but agrees on this one. |
| 14:43 | <gbee> | but Dibblah has got me wondering if instead of a simple on/off it should be a combo box ranging with values of Off, Low, Medium, High (mapped to actual skiploop options) |
| 14:43 | <danielk22> | dibblah: If it's integrated into the Video Playback profiles, it can just be made a default in the "Slim" profile. |
| 14:44 | <Dibblah> | gbee: See if there's any difference in benchmarking. |
| 14:44 | <Dibblah> | I doubt you'll see significant difference between nonkey and all |

| 14:49 | <gbee> | I'm happy to leave the commit for now until we can reach a consensus on the approach |
| 14:50 | <MrGandalf> | so, I suppose nobody has any thought regarding my dev list post about h264 streams. |
| 14:50 | <gbee> | mkrufky: we were wondering if you'd be interested in writing support for this, if we send you one? http://www.scan.co.uk/Products/ProductInfo.asp?WebProductID=808585 |
| 14:51 | <gbee> | MrGandalf: sorry, guess I missed it |
| 14:51 | <MrGandalf> | gbee: np |
| 14:52 | <mkrufky> | im not touching that with a ten foot pole, gbee |
| 14:52 | <mkrufky> | i dont even have a satellite |
| 14:52 | <gbee> | MrGandalf: the double length one? h.264 and decoding aren't really my thing either, so I can't help - sorry |
| 14:52 | <mkrufky> | and saa716x is bad news for linux |
| 14:52 | <Dibblah> | Well, they are rather expensive. |
| 14:52 | <gbee> | mkrufky: heh, ok |
| 14:52 | <Dibblah> | I personally don't have one either. |
| 14:52 | <MrGandalf> | gbee: I fear it's nobody's thing. :( |
| 14:53 | <Dibblah> | I have a dish, sure - But a satellite wouldn't get past household finance. |
| 14:53 | <mkrufky> | you will have a very difficult time dealing with that PCIe bridge chipset |
| 14:54 | <Dibblah> | Manu was saying negotiations over specs were ongoing before Christmas... |
| 14:54 | <mkrufky> | if it was a conexant bridge, then id manage to find a way to work on it, regardless of whether or not i actually have a satellite dish |
| 14:54 | <mkrufky> | Manu -- thats the key word |
| 14:54 | <Dibblah> | Indeed. |
| 14:54 | <mkrufky> | Manu is "working closely" with NXP on this driver |
| 14:54 | <mkrufky> | i have doubts |
| 14:55 | <gbee> | mkrufky: oh well, I feared as much, it would have been nice - ultra cheap, 2xdvb-s AND pcie |
| 14:55 | <Dibblah> | It's all about FUD. "We'll have drivers soon - Don't buy anything else!" |
| 14:55 | <mkrufky> | i have a feeling some other company might one day come out with such a product that uses some linux-supported PCIe bridge chipset, instead |
| 14:55 | <mkrufky> | just wait a few months |
| 14:55 | <MrGandalf> | usb tuners are the way to go |
| 14:56 | <Dibblah> | Network tuners are the way to go. |
| 14:56 | <clever> | usb also lets you use a laptop |
| 14:56 | <mkrufky> | i think usb is kinda silly for dvb-s , tbh |
| 14:57 | <gbee> | I'd just settle for a dvb-s2 card right about now |
| 14:57 | <clever> | ive got 2 laptops with tvout that would make real thin&silent frontends |
| 14:57 | <clever> | with the usb they can be master&front |
| 14:57 | <mkrufky> | wow -- i always stayed clear of this room, i thought it was for mythtv app development |
| 14:57 | <mkrufky> | now i know better |
| 14:57 | <gbee> | mkrufky: heh |
| 14:57 | <mkrufky> | i actually had an app devel question, thats why i am here |
| 14:57 | <clever> | same:P |
| 14:57 | <clever> | ive run into an anoying bug |
| 14:57 | <MrGandalf> | I find USB tuners to be more stable. |
| 14:58 | <gbee> | I've lead the channel astray over the last week |
| 14:58 | <clever> | when i delete a show it causes a long rescedule, causing the network connection to timeout, causing a deadlock |
| 14:58 | <gbee> | OK class, back to work |
| 14:58 | <mkrufky> | MrGandalf: try a DViCO Dual Digital "usb" and you'll change your tune |
| 14:58 | <Dibblah> | clever: Back to -users ;) |
| 14:58 | <jarle> | When mythtv is tuning to a new channel it seems to be blocking ALSA. If I am listening to a mp3 in the background and tell mythtv to change channel sound disappears for a second, does it HAVE to be this way for some reason, or is this a bug? Any ideas? |
| 14:58 | <MrGandalf> | well, I'm sure there are exceptions.. |
| 14:58 | <clever> | Dibblah: i can patch it myself:P, ive allready fix 2 of my other bugs |
| 14:58 | <clever> | was just wondering if some1 else has heardof/fixed it allready |
| 14:59 | <gbee> | jarle: we mute the channel to avoid squelch during the channel change |
| 15:00 | <gbee> | we can probably change the way we are doing it, I'm not familiar with the code in question, chances are we can just pause the audio instead and drain the buffer |
| 15:00 | <jarle> | gbee: oki, so ideally I should have "external" sound on another "channel" than mythtv is using then... if such a thing is possible... |

| 18:59 | <brunes> | hey MrGandalf - that channel map code works OK, btu there is a minor issue... if you change to a mapped channel, when you bring up the guide again, it is pointing at the *original* channel |
| 18:59 | <brunes> | so you lose your place in the guide |

| 19:16 | <kali67> | Hi, is there more info on the Python bindings for Mythtv , Any sample scripts ? |
| 19:16 | <kali67> | or a library for interacting with the backend ? How does mythweb do it ? |
| 19:17 | -!- | kormoc [n=kormoc@unaffiliated/kormoc] has quit [] |
| 19:18 | <foxbuntu> | kali67, what are you trying to do? |
| 19:18 | <kali67> | I'm trying to write some scripts ( like delete a set of shows or record a set of shows ) |
| 19:19 | <kali67> | currently I'm using scripts to drive the web interface which at best is a kludge |
| 19:19 | <Chutt> | changing channels around for qam tuners is a pain |
| 19:19 | <foxbuntu> | kali67, why not just bind your scripts to the mythconverg db on the be and modify the appropriate tables? |
| 19:20 | <brunes> | kali67: if you are running mythfrontend it has a pretty good telnet command API. The native myth protocol API i find is very poorly documented right no on the wiki; its a real moving target. the only way to understand it is grock the code yourself I think |
| 19:21 | <foxbuntu> | kali67, for what you are trying to accomplish, I am not sure why you need it to use the myth applications |
| 19:22 | <kali67> | foxbuntu: that is a an idea that I'd like to do as a last resort |
| 19:22 | <foxbuntu> | hmm ok |
| 19:22 | <kali67> | here's what I'm trying to do - on the command line, record say 5 hours or 6 hours of show on a particur channel |
| 19:23 | <kali67> | but I want to retain the program titles . |
| 19:23 | <foxbuntu> | retain the program titles where? |
| 19:23 | <kali67> | I want to do the equivalent of someone accessing mythweb and going to the program listing and selecting the shows for the next 5 hours for recording |
| 19:24 | <foxbuntu> | ok |
| 19:24 | <MrGandalf> | brunes: it brings you to the first that that channel appears on the guide. |
| 19:24 | <kali67> | I already have a script that I can run to record the shows on a "manual schedule "M |
| 19:25 | <foxbuntu> | kali67, all that info is still in the DB |
| 19:25 | <kali67> | for example - I can say record --channel=3 -starttime=13:00:00 --length=30 |
| 19:25 | <kali67> | foxbuntu: I guess, I will have to go that route |
| 19:26 | <foxbuntu> | kali67, Im thinking you could read the guide data from the db, parse out the upcoming program data from time x to time y |
| 19:26 | <kali67> | foxubunt: I do not exactly know all the tables and their dependencies |
| 19:26 | <foxbuntu> | then set a record for each show individually |
| 19:27 | <foxbuntu> | time x to time y on channel z (edit) |
| 19:27 | <brunes> | MrGandalf: no.. it brings you to the original mapped channel |
| 19:27 | <foxbuntu> | then you just use the data you found to generate a one time recording list |
| 19:27 | <brunes> | MrGandalf: In my example - I have channel 802 mapped to channel 2 |
| 19:27 | <kali67> | foxbuntu: if I'm accessing the db , then I might as well update the recording tables |
| 19:28 | <brunes> | MrGandalf: If I go into th eguide and pick channel 2, it tunes correctly. but if i then bring up the guide again, it says I am on channel 802 |
| 19:28 | <brunes> | it always goes to the original channel |
| 19:28 | <foxbuntu> | kali67, you could do it that way as well... I was just giving you the other option because of the worries about editing the right tables |
| 19:29 | <brunes> | kali67: You can easily connect to the MythFrontEnd telnet protocol at any time and tell it to start recording and stop recording |
| 19:29 | <brunes> | kali67: So you can justc all that from a crontab |
| 19:29 | <MrGandalf> | brunes: odd, doesn't do that for me. |
| 19:29 | <kali67> | foxbuntu: you are right, but the issue that I have faced is that I've had to reverse engineer the mythweb interface |
| 19:30 | <MrGandalf> | it stores the channum somewhere.. maybe change that to chanmap |
| 19:30 | <brunes> | kali67: Why? there is a pretty good 'help' command... |
| 19:30 | <foxbuntu> | kali67, join me in #mythbuntu-dev |
| 19:30 | <brunes> | MrGandalf: Does it store it in the guide? |
| 19:30 | <MrGandalf> | brunes: haven't a clue |
| 19:31 | <brunes> | MrGandalf: See, I think the problem is the code basically does a kind of "replace" with 2 -> 802 just beore the tuning. So, once tuned, all mythtv knows at that point is it is on channel 802, it doesn't know the channel you originally picked on the guide to arrive there |
| 19:31 | <MrGandalf> | it's startchannel in guidegrid I think |
| 19:33 | <brunes> | startChanID |
| 19:34 | <brunes> | hrm it looks like startChanId can be either a channel id or a channum... we'd have to change it to also check for a chanmap |

| 19:57 | <Chutt> | danielk22, did qam scanning ever get fixed? |
| 19:59 | <Chutt> | adding stuff to dtv_multiplex + channel manually is annoying =) |
| 20:00 | <brunes> | Chutt: Sure is :/ |
| 20:00 | <brunes> | I don't get why myth doesn't have support for this; so many providers are doing it now. |
| 20:00 | <brunes> | With my digital cable I had before I got DVB, the same channel was actually mapped to *three* differentnumbers for some of them |
| 20:01 | <brunes> | One or the old analog "where it used to be", one for the network grouping and one for the HD grouping |
| 20:04 | <GreyFoxx> | brune: That info is not transmitted in a fashion we can get at |
| 20:05 | <GreyFoxx> | scanning for QAM channels doesn't give you info like channel callsigns or "numbers" like they are displayed in the settop box. That's usually received later or downloaded by the stb |
| 20:05 | <brunes> | GreyFoxx: OK I will take that. Bt it would be nice for me to be able tomanually map a channel to another number like this via the GUi :/ |
| 20:06 | <GreyFoxx> | I do it via mythweb, |
| 20:06 | * | Anduin thought it was just a reference to the -release channel scanner crashing all the time |
| 20:06 | <brunes> | I dont mean edit the channel number (like mythweb), I mean make like a copy of it, like MrGandalf's patch allows (almost) |
| 20:07 | <brunes> | Anduin: I fin with current mythbuntu the -releasse scanner problems now allw ent away... makes me wonder ifg it was X related |
| 20:07 | <brunes> | either that or they backported something |
| 20:07 | <brunes> | because I was totally up to date the day before I upgraded and my scanner crashed |
| 20:07 | <danielk22> | chutt: Not yet, but I'm working on it. |
| 20:08 | <Chutt> | cool. |
| 20:08 | <Chutt> | they just redid all my digitals here |
| 20:08 | <Chutt> | absolutely nothing is the same :/ |
| 20:08 | <Chutt> | why's the dtv_multiplex required for the hdhr? =) |
| 20:10 | <danielk22> | chutt: if you could scan with the channelscan branch scanner and send me the contents of the channel scanning tables I could probably come up with a solution for your cable company.. |
| 20:11 | <danielk22> | dtv_multiplex stores the same stuff: frequency, modulation method, system info standard. |
| 20:13 | <danielk22> | I think you told me your cable company used a atsc major == constant + atsc minor == channum, which is detectable and a heuristic could be applied... |
| 20:16 | <danielk22> | tables needed: channelscan, channelscan_dtv_multiplex, channelscan_channel |
