Thanks a lot for your work. Now: I'm trying to stream a TS file containing H.264 video (encoded with x264) and tried many encoding parameters, but cannot get a decent quality (lots of jittering, VLC as a client complains about audio drifts, late frames, .....). Do you have a sample file or encoding parameters that works fine for you ?
