[Live-devel] Monochromatic MJPEG stream

[Paulo Henrique Silva]

Hi,

I'm working with guys at Elphel to enable RTP streaming of their raw
format (called JP4). The JP4 format is stored as MJPEG file with
single component JPEG frames. Elphel uses a custom RTP server, but the
client (mplayer) uses live55 library and without single component
support, all decoded JPEG frames get wrong headers.

Per RFC 2435, only three component JPEG files have a defined 'type' on
the RTP/MJPEG packet header.

I was wondering if a patch to support single component JPEGs on
live555 would be accepted, using a non standard 'type' field (type >
127),

Another possibility is to use a x-* field on the SDP file, as used to
support frame dimensions larger than 2048.

What's is the preferred way? If any.

Thanks a lot,

-- Paulo
