[Live-devel] MPEG2TransportFileServerMediaSubsession seekStream ...

[Massimo Zito]

Hi Ross,

when I send a seek ( RTSP ) for a TS file ( handled by
MPEG2TransportFileServerMediaSubsession ), MPEG2TransportStreamFramer
doesn't estimate TS packet duration correctly ... I have found a workaround
...

    void changeInputSource(FramedSource* newInputSource) { fInputSource =
newInputSource; }

  protected:
    MPEG2TransportStreamFramer(UsageEnvironment& env, FramedSource*
inputSource);
        // called only by createNew()

{

  void MPEG2TransportStreamFramer::doGetNextFrame() {
    // Read directly from our input source into our client's buffer:

      // Note: We assume that we're asked to seek only in normal
      // (i.e., non trick play) mode, so we don't seek within the trick
      // play source (if any).

+     fFramer->clearPidStatusTable();

  }



Is this work correct ?

Thank you

Massimo
