GStreamer | don't know | Ver: 0.10.18
Summary: h.264 audio/video out of sync
Component: don't know
AssignedTo: gstreamer-bugs at lists.sourceforge.net
ReportedBy: jay.kinzer at gmail.com
QAContact: gstreamer-bugs at lists.sourceforge.net
GNOME version: 2.21/2.22
GNOME milestone: Unspecified
Please describe the problem:
When playing h.264 content, especially larger .mkv files, the audio tends to
get out of sync with the video. This problem generally builds over time,
starting out in sync or barely out of sync, and gradually growing more and more
out of sync as the video progresses.
On some videos, pressing pause will re-sync the video temporarily, but it will
again get out-of-sync after a few minutes. I've tried watching several h.264
videos in both Totem and Elisa and have seen this issue in most of them. There
are a few videos which play fine, but they are the exception, not the rule.
I've also watched these same videos through VLC or mplayer (which don't use
gstreamer) and they play fine, with no out-of-sync issues.
Steps to reproduce:
1. Open a "large" h.264 file (i notice it the most on files of around 4GB's or
larger), in Totem or through Elisa media center (or any other media player that
2. Watch the video for several minutes, it usually starts in-sync but quickly
starts to get more and more out-of-sync.
3. Pressing pause and then play sometimes temporarily re-syncs the audio/video.
The video appears to play correctly but the audio gradually becomes out of
The audio and video should stay in sync throughout the entire movie.
Does this happen every time?
