[SOLVED] .mkv audio issues after updating x264, ffmpeg and mplayer

dresb · 2010-04-14 20:30:40

Since I updated to x264-20100410-1, ffmpeg-22837-2 and mplayer-31029-1 the audio of random mkv files is having issues. While it seems to be in sync with the video it sounds as if it was slowed down.

The problem was solved after downgrading back to the previous versions with:

pacman -U /var/cache/pacman/pkg/x264-20100312-1-i686.pkg.tar.xz
/var/cache/pacman/pkg/ffmpeg-22511-1-i686.pkg.tar.xz
/var/cache/pacman/pkg/mplayer-30886-1-i686.pkg.tar.xz

I can't pinpoint the precise culprit using the binary packages and have no time right now to recompile them and track the problem individually, sorry.

is the 3rd time i've seen this issue. i'll wait couples of days more and update them again to new revisions.

for debugging purpose, can you tell me what vo are you using? or some usefull logs passing -v to mplayer?

I reinstalled the new versions and tried again but the problem seems to be independent of the -vo (or -ao) drv. I even tried null as -vo but the sound is still distorted. The video plays fine.

The logs of the current (problematic) versions:

i see that in the previous version is using other audio codec and i've search in the svn history and i found:

r30918 | diego | 2010-03-17 14:39:21 +0200 (Wed, 17 Mar 2010) | 4 lines

Prefer FFmpeg AAC decoder over libfaad.
This is a tentative change to give the decoder more testing;
it can always be reverted in short order if it turns out suboptimal.

1) basically save the /etc/mplayer/codecs.conf from the older version and use that. see if is working. NOT RECOMMENDED
2) without messing with codecs.conf

add in mplayer.conf

ac=faad,

which will force FAAD decoding if it detects AAC audio in a file, while falling back to appropriate decoder for all others. Make sure you add the comma at the end.
