[Telepathy] Video call with GTalk

[flower bean]

Thanks very much for your response.
I was create Voice call successfully via call below API:
QList<Tp::MediaStreamType> request_types;
        request_types.append(Tp::MediaStreamTypeAudio);
        mRetValue = (*mWaiter)( mChannel->requestStreams( aTarget,
request_types) );
*but fail to create Video call as below(especially no audio):*
        request_types.append(Tp::MediaStreamTypeVideo);
        request_types.append(Tp::MediaStreamTypeAudio);
        mRetValue = (*mWaiter)( mChannel->requestStreams( aTarget,
request_types) );
Channel fully ready, Audio/Video stream created successfully, but there is
no audio and video output, what do I need to do else?

Thanks in advance!
