[FFmpeg-devel] [PATCH] Support the ASF_JFIF_Media stream type

[Martin Storsjö]

Hi,

I've tried to add support for decoding the stream in issue 2070, 
rtsp://melpomene.mmedia.upv.es/RETRANS_PR_01. These three patches are 
needed for decoding it properly (in addition to a fix to rtpdec_asf, that 
I'll send in a separate thread).

The stream header contains a new guid that wasn't supported before, that 
according to a little googling is named ASF_JFIF_Media. The stream header 
doesn't seem to contain enough data to pose as a normal video stream 
header, so the check in patch 3 is necessary to avoid reading bogus data. 
Or if we consider this as a completely separate stream type (even if the 
type is AVMEDIA_TYPE_VIDEO), we perhaps should check if codec_id == 
CODEC_ID_MJPEG and read a different kind of stream header in that case.
