 |
|
I have setup a playback profile to always use xvmc as follows:
Setup -> TV Settings -> Playback -> Playback Profiles (3/9) -> Add New -> [enter playback profile name] -> Add New Entry ->
Match Criteria: > W: 0 H: 0
Decoder: Standard XvMC
Video Renderer: xvmc-blit
When I tune to a High Definition channel, I get stuttering audio, choppy video and the following frontend log messages:
| Code: | 2008-04-27 18:32:18.443 TV: Changing from None to WatchingLiveTV
2008-04-27 18:32:18.448 The realtime priority setting is not enabled.
2008-04-27 18:32:18.548 Video timing method: USleep with busy wait
_xvmc_create_context() returned incorrect data size!
Expected 30, got 2
2008-04-27 18:32:19.594 VideoOutputXv Error: Unable to create XvMC Context, status(11): BadAlloc
2008-04-27 18:32:19.595 VideoOutputXv Error: Could not open XvMC port...
You may wish to verify that your DISPLAY
environment variable does not use an external
network connection.
2008-04-27 18:32:19.607 VideoOutputXv: Desired video renderer 'xvmc-blit' not available.
codec 'MPEG2' makes 'opengl,xv-blit,xshm,xlib,' available, using 'opengl' instead.

2008-04-27 18:32:20.218 NVP: Enabling Audio
2008-04-27 18:32:21.243 WriteAudio: buffer underrun |
I think this may be related to the following reported bugs, but I am not sure: http://bugs.gentoo.org/show_bug.cgi?id=201095 and http://bugs.gentoo.org/show_bug.cgi?id=219149 (I have added a comment to bug #201095)
Any help is always appreciated.

I copied the contents of /usr/portage/media-tv/media-tv/mythtv to /usr/local/portage/media-tv/media-tv/mythtv and added the following line to /etc/make.conf:
| Code: | | PORTDIR_OVERLAY="/usr/local/portage" |
Then I edited /usr/local/portage/media-tv/media-tv/mythtv/mythtv-0.21_p17100.ebuild in a similar manner as this patch for mythtv-0.21_pre15025.ebuild which was published as the fix to bug #201095:
| Code: | src_compile() {
local myconf="--prefix=/usr
--mandir=/usr/share/man
--libdir-name=$(get_libdir)"
use aac && myconf="${myconf} --enable-libfaad"
use alsa || myconf="${myconf} --disable-audio-alsa"
use altivec || myconf="${myconf} --disable-altivec"
use jack || myconf="${myconf} --disable-audio-jack"
use opengl-video && myconf="${myconf} --enable-opengl-video"
use xvmc && ! use video_cards_via && ! use opengl-xvmc && \
myconf="${myconf} --enable-xvmc"
use xvmc && use video_cards_via && myconf="${myconf} --enable-xvmc \
--enable-xvmc-pro --disable-xvmcw"
use xvmc && use video_cards_nvidia && use opengl-xvmc && \
myconf="${myconf} --enable-xvmc --enable-xvmc-opengl --disable-xvmcw"
# Following two lines added -- ALS - 4/28/4008
use xvmc && use video_cards_nvidia && \
myconf="${myconf} --xvmc-lib=XvMCNVIDIA --enable-xvmc --disable-xvmcw"
# nvidia-drivers-71 don't support GLX 1.4 |
/usr/local/portage/media-tv/mythtv/Manifest was updated as follows:
| Code: | | # ebuild /usr/local/portage/media-tv/mythtv/mythtv-0.21_p17100.ebuild digest |
For an unkown reason /etc/init.d/mythbackend was deleted the first time I used the modified ebuild. I had to rebuild mythtv from /usr/portage/media-tv/mythtv/ then make a backup copy of /etc/init.d/mythbackend
I rebuilt from /usr/local/portage/media-tv/mythtv/ a second time then restored /etc/init.d/mythbackend from the backup copy.
After a few tweaks to mythtv settings, I now have high definition without the stuttering audio and choppy video. |
