I have then same question,
TV in VideoCaptureElement is OK ,but no audio output and can't change the Channel.
please help me
Thank you very much
i am not really an expert.., but will give it a try.
try adding audio renderer to IGraphBuilder object just like
VideoMixingRenderer9 video renderer is added.
refer below code line.
m_aRenderer = AddFilterByName(m_graph, FilterCategory.AudioRendererCategory, MultimediaUtil.AudioRendererNames);
this simply picks up first audio out device present in machine and add IBaseFilter for this in graph instance.
Then add below code lines to render audio from TVTuner device to this filter.
hr = graphBuilder.RenderStream(PinCategory.Preview, MediaType.Audio, m_captureDevice, null, m_aRenderer);
I am using UMAX USB TV Tuner with cable connection.
Works perfect for me!!!
