GStreamer | gst-ffmpeg | Ver: HEAD CVS
Summary: gst-ffmpeg isn't thread-safe
Product: GStreamer
Version: HEAD CVS
Platform: Other
OS/Version: Linux
Status: UNCONFIRMED
Severity: critical
Priority: Normal
Component: gst-ffmpeg
AssignedTo: gstreamer-bugs at lists.sourceforge.net

Run many instances of ffmpeg decoders and/or encoders simultaneously and you get
the following message: "insufficient thread locking around avcodec_open/close()".
It seems a lock must be held before calling avcodec_open/close(). When you get
the warning, ffmpeg doesn't initialize properly and problems start happening. We
probably need a static mutex that both gstffmpegenc and gstffmpegdec can lock.
