I tested various files. Mpeg format works ok but avc (x264) cause bug. Similar problem with mplayer.

Movie-Aspect is 1.78:1 - prescaling to correct movie aspect.

MPlayer interrupted by signal 6 in module: decode video
- MPlayer crashed. This shouldn't happen.
It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
gcc version. If you think it's MPlayer's fault, please read
DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
won't help unless you provide this information when reporting a possible bug.

is a x264 10bits?

VDPAU can't handle x264 with 10bits [Hi10p] use XV instead

Yesterday I could play all my x264 files. Today with the updates of vlc, mplayer, ffmpeg, ... I can't :(

Downgrading this files:
ffmpeg-1:1.0.1-1-x86_64.pkg.tar.xz
mplayer-35421-2-x86_64.pkg.tar.xz
vlc-2.0.5-2-x86_64.pkg.tar.xz
x264-20121113-1-x86_64.pkg.tar.xz

...and all works fine again. Maybe the bug is in new /usr/lib/libx264.so.

mplayer used to work fine in testing but i've got a new snapshot. is not related to this issue.

More people have similar bugs:

https://bbs.archlinux.org/viewtopic.php?id=158303

mplayer bug has been bisected as a bug in ffmpeg. expect new mplayer package tomorrow.

as for libva, i'm still debuging.

EDIT: nothing

for vlc, only vdpau provider is affected?

I can't test VLC with libva-intel-driver, I haven't any computer with an intel graphic adapter.

Mplayer works fine again with ffhvpdau264. Thanks a lot.

On my laptop (i686) with intel gpu everything seems to be ok.

libva 1.1.0-2
libva-intel-driver 1.0.19-1
vlc 2.0.5-3
ffmpeg 1:1.1.2-2
x264 20130206-1

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)

On my desktop (i686) with nVidia the problem is there.

03:00.0 VGA compatible controller: NVIDIA Corporation G98 [GeForce 8400 GS] (rev a1)

please report upstream to ffmpeg.

Is it related to this?

https://ffmpeg.org/trac/ffmpeg/ticket/2288

is it possible. please test that patch.

I will do later this day.

VLC gpu accel not working after upgrade on libva-intel-driver, x86_64.

I did an FFmpeg git-bisect and the results is the commit bellow.

nice job Alexander, have you contacted upstream about it?

I tried to take advices form the official ffmpeg IRC channel but had no luck. I still can't confirm if this an FFmpeg or VLC or whatever issue. I opened a thread to the VLC forum also.

I don't know If I should fill a bug report for FFmpeg with something like "VLC can't use hardware decoding because of commit..."

I don't even know what the offending commit does. Maybe VLC team should change something in order to comply with the new FFmpeg.

Please enlighten me! :D :D :D

mate, please apply this patch to ffmpeg:
http://git.videolan.org/?p=ffmpeg.git;a=blobdiff;f=libavcodec/h264.c;h=da749a241d5647751cb5a961429abb6657a79a00;hp=56ef1092bd4509697f11b76ae97757bbc03aef14;hb=c6f59b95c529baf2ea6729ab9089fddce3ddd86a;hpb=6407800521d26b103db4c22d9de709e957381e4b

is fixing the problem for me.

Yep, the above patch fixes the problem for me too (nVidia card, libva-vdpau).

All works fine again in VLC. Thanks!!

yuhu!
