Hi, I am seeing this bug with Totem (3.8.2-4+b1) and Snappy (1.0, from
source, not in archive currently) in Sid (gstreamer 1.2.3-1).
For me it occurs in most, but not all, h264+mkv files. My h264+MP4
files are not affected, nor are any non-h264 files as far as I can
tell. Non-gst players (mplayer, vlc) have no issue with these files.
The error is either
** (snappy:20884): CRITICAL **: gst_video_codec_frame_unref: assertion
'frame-ref_count 0' failed
or else (it varies from run to run):
** (snappy:20914): CRITICAL **: gst_video_codec_frame_ref: assertion
'frame != NULL' failed
Attaching GDB run and backtrace from snappy. Let me know if I need to
do things differently.
Thanks,
Kelly Clowers
