--- Comment #5 from Zebediah Figura z.figura12@gmail.com --- Your symptoms are different from mine, and I'm increasingly suspecting that there's some memory corruption or something going on. Even in the "good" case there's this:
0024:trace:strmbase:strmbase_dump_media_type Dumping media type 0x1950b0: major type MEDIATYPE_Video, subtype MEDIASUBTYPE_RGB32, fixed size samples, format type FORMAT_VideoInfo. 0024:trace:strmbase:strmbase_dump_media_type Dumping format 0x838818: source (0,0)-(640,292), target (0,0)-(640,292), 0.0 sec/frame, size 640x-292, 1 planes, 32 bpp, compression 0, image size 747520.
** (wine:99334): CRITICAL **: 03:38:00.532: gst_video_info_to_caps: assertion 'info->finfo->format != GST_VIDEO_FORMAT_UNKNOWN' failed
which clearly doesn't seem to affect the functionality, but I really don't think it should happen.
