[Red5] red5 RTP to RTMP restreamer error, please help

[Jeremy Morton]

Well right now I'm able to hack around the bug by, in FP10 or later, 
pause/unpausing upon the first key frame, which seems to fix things. 
Not ideal, certainly.  But Art (I think) mentioned something a while 
back about sending Flash a packet telling it to use video for syncing 
rather than audio.  I never got that to work but if it could be made to 
work I think it would be a much better solution than sending a 'dummy' 
blank audio stream, given that we have no real audio to send.

Best regards,
Jeremy Morton (Jez)
