Description

Summary of the bug:
When I'm trying to stream jpeg2000 from gdigrab (for example), I get an error on server:

720 -vcodec libopenjpeg -pix_fmt yuv444p -f rtsp -rtsp_transport tcp rtsp://loca

https://tools.ietf.org/html/rfc5371 Describes transmitting JPEG2000 over RTP/RTSP, but not implemented yet.

This is a future request. It is my first ticket, sorry if I made anything wrong.
