Hi,

I use BodyReader to get video frames and wrote the code to test:

Code:

 
   VideoDataHandler *pHandler = new VideoDataHandler(BodySID);

   BodyReaderPtr BodyParser = new BodyReader(theFile);
   BodyParser->MakeGCReader(BodySID);
   GCReaderPtr ThisReader = BodyParser->GetGCReader(BodySID);
   ThisReader->SetDataHandler(TrackNumber_v, pHandler);// I've got the video track number
   for(;;)
   {
        cout<<"BodyParser->Tell(): "<<BodyParser->Tell()<<endl;
      bool Result = BodyParser->ReadFromFile();
      if(!Result)
      {
          if( BodyParser->Eof())
         {
            cout<<"End of file."<<endl;
            break;
         }
         BodyParser->ReSync();
      }
   }

The HandleData() is simple:

Code:

bool VideoDataHandler::HandleData(GCReaderPtr Caller, KLVObjectPtr Object)
{
        cout<<"In VideoDataHandler::HandleData"<<endl;
      return true;
}

The problem is:
Using BodyParser->ReadFromFile() all video frame would be parsed.
Using BodyParser->ReadFromFile(true) the HandleData() will be called only once. Than "End of file."
Who can tell me why? Was the ReadFromFile(true) wrongly used here?

I use ReadFromFile(true) because I want to stop the process after a certain video frame has been found.

Using ReadFromFile() all KLVs in a partition will be parsed, how can I stop it after the wanted video frame has been found?

I made it.
Just add Caller->StopReading() into VideoDataHandler::HandleData() than the process can be stopped.
