[Live-devel] Can live555 read RTP data from ffmpeg?

If your only source of MPEG TS data is from files, then you don't need to use "ffmpeg" at all.  Instead, you can stream your "file.ts" directly from our server.  (If you are using "testOnDemandRTSPServer", then you rename "file.ts" as "test.ts".  If you are using "live555MediaServer", then you don't need to rename your file, as long as its name ends with ".ts".)

By this I presume that you changed the definition of "inputAddressStr" to:
	char const* inputAddressStr = NULL;

I suggest first using "testRTSPClient" as your RTSP client application, instead of VLC.

No, I don't think so, assuming that your "ffmpeg" command generates RTP-encapsulated MPEG Transport Stream packets (with the correct RTP payload format code: 33).  However, I don't know enough about "ffmpeg" to say for sure whether it's doing what you intend.
