| mishehu | greets folks. I have an atom n330 dual core ION, and though it's terribly underpowered, I can play some files well and others can't seem to play at all viewably. | 04:04 |
|---|---|---|
| mishehu | for example, one matroska that I have has this for a video stream: Video: h264 (High), yuv420p, 1280x720, SAR 1:1 DAR 16:9, 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc (default) , and this file plays perfectly well | 04:05 |
| mishehu | the other file, Stream #0:0(eng): Video: h264 (High), yuv420p, 1280x720 [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 1k tbn, 47.95 tbc (also matroska), plays terribly. I notice that if I try to play this with vlc, I get the same performance, even if I try to adjust the thread settings in the ffmpeg/libavc decoder. It only ever maxes out one cpu, and never uses the other cpu. | 04:06 |
| mishehu | does anybody have any suggestions as to what I may be able to do (besides replacing the hardware) to be able to play this second file? | 04:07 |
| dekarl | mishehu: if you max out a CPU then something is going wrong. the decoding should be done on the GPU and not tax the CPU that much. | 04:45 |
| dekarl | I'd verify if the hardware decoding is used or not first | 04:46 |
| mishehu | dekarl: well the nvidia drivers are installed, and though it's an ION does that mean that the h264 is done on the nvidia card itself? | 06:19 |
| mishehu | or was it only a subset of the processing? | 06:19 |
| mishehu | I tried adjusting the frame buffer in the bios so that it had 512 mb instead of 64 mb (the prior setting), yet mythfrontend and vlc still end up using 100% of one of the cores | 06:37 |
| dekarl | hmm, I can look at my ION | 06:39 |
| dekarl | what decoding profile have you selected in the frontend setup? Should be VDPAU slim/normal/high | 06:40 |
| mishehu | remind me please what setup menu those options are under | 06:41 |
| mishehu | that under playback profiles? | 06:44 |
| mishehu | looks like that was it | 06:48 |
| mishehu | I set vdpau to highest, and the cpu's only at 17% | 06:49 |
| mishehu | thanks for the help dekarl | 06:49 |
| dekarl | glad that it was so easy (sorry I'm a bit slow, I have baby duty this morning :) | 06:51 |
| mishehu | eh it's ok | 06:55 |
| mishehu | I reloaded that machine a few times | 06:55 |
| mishehu | that's why I missed setting it for vdpau in teh first place | 06:55 |
| mishehu | so it does about 17% cpu for 720p h264, and 6-7% for standard dvd | 06:56 |
| mishehu | much much better | 06:56 |
| dekarl | sounds about right, too | 06:57 |
| mishehu | night and day | 06:58 |
| mishehu | I was getting quite irritated | 06:58 |
| mishehu | now it works :-) | 06:58 |

| James2 | [14:59:17] <James2> hmm and im unable to tune to one of the satelite muxes... | 15:12 |
| James2 | [14:59:20] <James2> http://www.bbc.co.uk/reception/info/sat_frequencies.shtml | 15:12 |
| James2 | [14:59:37] <James2> DSAT8 imtuned to, but DSAT4's settings just give me a timeout and no channels | 15:12 |
| James2 | [14:59:55] <James2> is that likely to happen if the dish alignment was slghtly out | 15:12 |
| James2 | [15:00:16] <James2> but i dont understand why i can get one of its muxes but not another, surely if it can see the satelite, it can see it right? | 15:12 |
| sabhain | anyone here using multiple monitors with 12.04? | 17:27 |
| James2 | michael@myth-bedroom:/data$ mythtv-setup --help | 21:54 |
| James2 | xprop: unable to open display '' | 21:54 |
| James2 | (zenity:19556): Gtk-WARNING **: cannot open display: | 21:54 |
| James2 | any reason i cant run the mythtv-setup cli using ssh? | 21:55 |
| rhpot1991 | James2: it requires x | 22:06 |
| rhpot1991 | it isn't cli | 22:06 |
| rhpot1991 | you might be able to ssh -X it | 22:07 |
| rhpot1991 | probably easier to just vnc though | 22:07 |
| James2 | it is, your wrapper script just doesnt allow it due to its use of xterm | 22:07 |
| James2 | what i expected was the output from | 22:07 |
| James2 | mythtv-setup.real which i didnt know youd renamed and wrapped | 22:07 |
| James2 | mythtv-setup.real --help correctly returns its usage | 22:08 |
