[QUOTE="gibman, post: 314195, member: 25430"] thx. look at; private void AudioVideoEventHandler(PidType pidType) { Log.Info("audioVideoEventHandler {0}", pidType); // we are only interested in video and audio PIDs if( pidType == PidType.Audio ) { _eventAudio.Set(); } if (pidType == PidType.Video) { _eventVideo.Set(); } } it seems like only the audio event seen event is being caught by c# code. are u able to compile the c++ filters ? in tswriter.cpp STDMETHODIMP CMpTs::SetVideoAudioObserver(int handle, IVideoAudioObserver* callback) { CTsChannel* pChannel=GetTsChannel(handle); if (pChannel==NULL) return S_FALSE; pChannel->m_pTimeShifting->SetVideoAudioObserver(callback); return S_OK; } It seems like the "pChannel->m_pTimeShifting->SetVideoAudioObserver(callback);" comes too late, since the first video PID has already been detected. I can see this by looking at tswriter.log 13-10-2008 13:41:55.335 Recorder: TIMESHIFT start of video detected 13-10-2008 13:41:55.350 Recorder: TIMESHIFT SetVideoAudioObserver observer ok 13-10-2008 13:41:55.397 Recorder: TIMESHIFT start of audio detected so the video is detected but the videoaudioobserver is still not connected, so no events to c# code. then the videoaudioobserver is connected. and audio is detected and c# is notified. /gibman [/QUOTE]
