[Live-devel] some problems with ByteStreamMultiFileSource

[Karlov Andrey]

but we haven't! in first mail I have explained why.

This is because we check for EOF only before reading!

Then we read next time, we before check for EOF,
but there's no EOF state and we try to read,
and of course we read 0 bytes, but now we have EOF state =)


and it's handled not here, as it should be:

    void ByteStreamFileSource::doGetNextFrame() {
        if (feof(fFid) || ferror(fFid)) {
        handleClosure(this);  <--- SWITCH TO NEXT FILE
        return;
        }
     ....


but here:

void MPEG2TransportStreamFramer::afterGettingFrame1(unsigned frameSize,
                            struct timeval presentationTime) {
      fFrameSize += frameSize;
      unsigned const numTSPackets = fFrameSize/TRANSPORT_PACKET_SIZE;
      fFrameSize = numTSPackets*TRANSPORT_PACKET_SIZE;
      if (fFrameSize == 0) {
        // We didn't read a complete TS packet;
        //assume that the input source has closed.
        handleClosure(this); <-- EXIT FROM PROGRAM,
				NO SWITCH TO ANOTHER FILE
        return;
      }
    ......
