Hi everyone,

I am now developing an conferencing application which use webcam as a video device. I am able to preview the webcam and capture image from it using directshow following the article here: DirectX.Capture Class Library[^]

The directshow lib saves the video directly to my disk and I cannot find a way to get the video stream directly from it. I try to send the video by sending it frame by frame in JPEG format using RTP. These frames are images I captured from the webcam. I know that I should compress it as MJPEG or MPEG but I cannot find any codec capable of doing so. And unfortunately, I even cannot successfully viewing the video on the receiver side. There is error said "Invalid parameters" when I try to save received RTP packets back to JPEG format for viewing.

So could you tell me which step I have to do to get this done? I searched google for a days and cannot find an answer. Please help me out.
Thanks in advance.
