Summary:                    Sent RTP video packets have a timestamp based on a
8000 Hz clock instead of 90000 Hz when mark bit is on
Description: 
When you ast_write() a video packet, you are supposed to put the mark bit
into the LSB of the subclass member:

f->subclass = AST_FORMAT_H263 | 1;

This makes this conditional in ast_rtp_raw_write() true while it should be
false:

if (f->subclass & AST_FORMAT_AUDIO_MASK) {

The solution is simple: invert the video and audio code paths. First check
for video, and then if video is not present check for audio.
