[Live-devel] Creating a RTSP stream from DVB-T hardware card

[Ryan Walklin]

OK, I promise this will be the last time i write ;)

I'm not convinced my code is the problem now (although it most likely  
still is). I've rewritten my plugin code to simply write packets to  
stdout, then piped it into a file (temp.ts). This plays back fine in  
VLC.

However, using either testMPEG2TransportStreamer or live555MediaServer  
to stream it to VLC doesn't work. testMPEG2TransportStreamer dumps a  
stream of "Missing Sync Byte" errors to the console until killed,  
whereas live555MediaServer allows the stream to load in VLC, however  
doesn't play, and examining the VLC info window shows the incoming  
stream has 16 streams (the file has only a single audio and video  
stream).

Strangely ts files saved using the EyeTV interface stream fine. My  
hypotheses then are either the raw stream coming from my card is not  
entirely spec-compliant, or EyeTV is presenting me incorrect data; or  
that the liveMedia library does not entirely support NZ's DVB format.

I'll keep working on it, but I think I might need to get Elgato to  
shed some light.

Regards,

Ryan
