There was a crush in ffmpeg, when avcodec_copy_context was called on context of codec that has no class in priv context. It is fixed by: [PATCH] lavc/options: don't copy priv context when it is not AVOption object. Calling this function on non-avclass object is misuse of this function of course. So probably patch is not needed, but maybe doesn't hurt. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
