Description

Payload encode JPEG pictures into RTP packets according to RFC 2435. For detailed information see: http://www.rfc-editor.org/rfc/rfc2435.txt

The payloader takes a JPEG picture, scans the header for quantization tables (if needed) and constructs the RTP packet header followed by the actual JPEG entropy scan.

The payloader assumes that correct width and height is found in the caps.
