    These bugs should be in their own bug report threads - this thread is for feedback on the TsReader.ax dev versions, these may not be TsReader.ax problems (and they will get lost in this 80+ page thread....)

    The files play OK using TsReader.ax + DivX AAC audio decoder + MS DTV-DVD video decoder (or PDV11 video decoder) in GraphStudio, so this is a decoder problem.

    (LAV audio + LAV video => green screen + no audio on my system, using both LAV splitter and TsReader.ax)

    LAV splitter + LAV audio decoder combo plays the file correctly here, so it could be an issue with TsReader.

    Yes, seems to be tsreader bug, because i have tested all relation with LAV

    Tested with graphstudio, Ts is played fine With LAV Codec / splitter, only Tv Codec don't work and the only thing we can't change is Tsreader.

    OK - I can reproduce the problem with TsReader.ax + LAV audio decoder. Using DivX (or Mainconcept) AAC decoders works OK, so that is a solution for now.

    This isn't a new problem - v0.5.63 (MP 1.3 version) also has the problem - so I'll just put it in Mantis for now.

    I've had a play around with the code, but no real clues as to exactly what's wrong (audio pin PMT info looks OK in GraphStudio etc) - it's 'raw' AAC rather than LATM AAC, but I've got other test files using that and they play OK....

    2. radio rtsp stream don't work with Dedicated server @EdG found bug when Radio (RTSP provider) is used with Dedicated server + Client system only, audio is played 2-3 sec, after no sound ...
    No real idea from the logs about that problem - I suspect it's more likely to be the server end because it looks like TsReader.ax is not receiving data sometimes.

    Bug (2) should be a separate thread - I don't think it is related to Bug (1) (and it's confusing to have two bugs in one thread)
