------- Additional Comments From Tim-Philipp Müller  2005-12-16 16:30 -------
I've committed the actual patch, as I really want this to go into the upcoming
release.

A separate bug #324279 has been filed to make sure we add the build stuff for
unit tests at some point, with reference to the test case here.

        * ext/ffmpeg/gstffmpeg.c: (gst_ffmpeg_avcodec_open),
        (gst_ffmpeg_avcodec_close):
        * ext/ffmpeg/gstffmpeg.h:
        * ext/ffmpeg/gstffmpegdec.c: (gst_ffmpegdec_close),

        (gst_ffmpegenc_getcaps), (gst_ffmpegenc_setcaps),
        (gst_ffmpegenc_change_state):
          Do proper locking around avcodec_open() and avcodec_close()
          (fixes #322254, patch by: Sebastien Cote and Luca Ognibene).
