c#/c++ expert to deliver a client server application that will allow IP based RTP/UDP video/audio conferencing between 25 people.
You should be using c# (preferred, otherwise c++ also ok as long as APIs can be called from c#).
Idea like as follow:
RTSP Client (Sending part): Sending Filter Graph at A is composed of:
1-Audio Capture filter to capture audio from the microphone.
2-Video Capture filter to capture video from webcam.
3-PCM wrapper to convert the data to PCM.
4-speex transform filter to encode the PCM data into configured audio codec.
5-Theora filter to encoder the video data into configured video codec.
6-RTP Send Filters
1-RTP Receive filters.
3-RTP Send Filter.
RTSP Client (Receive part): 1-RTP Receive filters.
2-Theora filter to decode the Theora into video data.
3-speex transform filter to decode the speex data back into PCM.
4-Render video on desktop panel.
5-Audio Render Filter to render the audio data to the sound card.
Audio/Video Codec Supported required:
Video: [url removed, login to view], [url removed, login to view]+, [url removed, login to view], Mpeg4

Resolution: QCIF to HD
Please ensure following parameters:
1 Ensure video and audio are synchronous and delay (latency) is <1 second.
2 4 bitrate profiles for client end: 64kbps (10fps) (QCIF), 128kbps, 256kbps(30fps) and 756kbps (HD)
3 Upload and download Bandwidth requirement for conferencing on the client should be equal to bitrate selected.
4 Upload and Download Bandwidth requirement on the server should be equal to bitrate*No of Clients.
5 Ensure Jitter buffer and Echo issues are not there.
6 Audio and video quality should be comparable to skype.
7 CPU usage on client and server should not exceed 25% for core 2 duo [url removed, login to view] machine with 1GB of RAM.
