How can we develop the Source Filter for RTP Receiver and set its media type ?...

How can we develop the Source Filter for RTP Receiver ?...
We can do one thing.

1.Develop the Source filter with Dynamic Output Pin,That means the output pin's buffer size may vary.

2.RTP receiver Filter must send the output data to its outptut pin based on the Frame. if the Frame is wrapped over more than one RTP packet, we have to send it over the network. For Doing this one develop the Separate class which will separate the RTP header and assemlble them as frame.
3.Look on MWS source Filter for Dynamic Output Pin.
GetStreamCount()
for(int i = 0; i < GetStreamCount(); i++)
{
StreamInfo stInfo = GetStreamInfo(i);
if(stInfo->id == VIDEO) { //Video is available in a Stream
stInfo->GetVideoFormat();
}
else if(stInfo->id == AUDIO)
{ //Audio is available in this stream stInfo->GetAudioFormat(); }
stInfo->GetExtraInfo() // Extra Header...
}
1.GetStreamInfo()
2.TrackId

VideoInfoHeader also must be set at the time of creating the Output Pin.
