[Live-devel] Streaming the same MEPG2 file circularly, only audio but no video

[pan ke]

Sorry for my late reply
my source data is MPEG Program Stream, and I create a new file
combining the two copies of my original file together, and I stream it
again using testOnDemandRTSPServer, the problem happened again.

I also use testMPEG1or2AudioVideoStreamer to stream the file, when i
use the original file, it can stream the file again and again without
error(actually, this amounts to rerun the streamer). however, when i
use the combined file. the error still exists. I can only get the
audio, but no video.
