ext/ffmpeg/gstffmpegdec.c (struct _GstFFMpegDec)

Browse source 
Original commit message from CVS:
* ext/ffmpeg/gstffmpegdec.c (struct _GstFFMpegDec)
(gst_ffmpegdec_open, gst_ffmpegdec_negotiate):
Cache the pixel format value and renegotiate the pipeline
if this value changes. Fixes segfault when decoding a
stream with different colorspaces like a sequence of jpeg.
