[Live-devel] Matroska BANK_SIZE overflow

[PROMONET Michel]

            Hi Ross,

Surely I badly use the matroska parser...
What I was trying to do is to connect each matroska subsession to a sink. In fact I don't need ServerMediaSession, it is just to get the FramedSource corresponding to a subsession.

The following code seem to works with some mkv but produce an overflow of BANK_SIZE with the file I send previously

#include "liveMedia.hh"
#include "BasicUsageEnvironment.hh"

static char newMatroskaDemuxWatchVariable;
static MatroskaFileServerDemux* demux;
static void onMatroskaDemuxCreation(MatroskaFileServerDemux* newDemux, void* /*clientData*/) {
  demux = newDemux;
  newMatroskaDemuxWatchVariable = 1;
}

int main(int argc, char** argv) {
  TaskScheduler* scheduler = BasicTaskScheduler::createNew();
  UsageEnvironment* env = BasicUsageEnvironment::createNew(*scheduler);

  // A Matroska ('.mkv') file, with video+audio+subtitle streams:
  {
    char const* inputFileName = "test.mkv";
    ServerMediaSession* sms = ServerMediaSession::createNew(*env, inputFileName, inputFileName,inputFileName);

    newMatroskaDemuxWatchVariable = 0;
    MatroskaFileServerDemux::createNew(*env, inputFileName, onMatroskaDemuxCreation, NULL);
    env->taskScheduler().doEventLoop(&newMatroskaDemuxWatchVariable);

    ServerMediaSubsession* smss = NULL;
    unsigned fileSinkBufferSize = 100000;
    while ((smss = demux->newServerMediaSubsession()) != NULL) {
            sms->addSubsession(smss);
            MediaSource* source = demux->newDemuxedTrack(0,smss->trackNumber());
            MediaSink* sink = FileSink::createNew(*env, smss->trackId(),fileSinkBufferSize, False);
            sink->startPlaying(*source,NULL,NULL);
    }
  }

  env->taskScheduler().doEventLoop();

  return 0;
}

Thanks for your help.

            Michel.

Adding a missing word to my previous answer:


How are you parsing/demultiplexing this Matroska file?  Are you using your own application (that presumably uses the API in "liveMedia/include/MatroskaFile.hh")?  If so, then please [provide] the code for a simple application (as simple as you can make it) that reproduces this problem when  parsing/demultiplexing this Matroska file.
