[Live-devel] VLC playback problem using live555MediaServer with RTP over TCP

Thu Aug 2 02:35:35 PDT 2012

Hi Ross,

With the latest live555MediaServer , when I use VLC test a mp3 stream, it
works fine when VLC’s live55 stream transport mode setting is HTTP.
However, if the setting is changed to RTP over RTSP(TCP) .
live555MediaServer does receive the request, produce and send back the
stream output. But live555MediaServer will fail in sending packets back
before the stream finish, and I can’t hear any sound.  I don’t know what
might caused the issue, could you give advice?

FYI, here is some live555MediaServer output shown below:
