VLC streaming and Blackmagic Intensity Pro

Hello, I have some technical knowledge but VLC goes a bit over my head.

I have a Blackmagic Intensity Pro card and i would like to stream 720p (without encoding loses) to a VLC client' in LAN.

I was able to do h264 but the result is really looking ugly, so I would like to see video RAW(?) and maybe an MP3 audio or WAV to be streamed.

Which command must I use?

Thanks in advance,

AFAIK you cannot stream RAW video with VLC. One RAW frame of 720p would be 1280x720x3 = 2 764 800 bytes. Multiply that with 30 for 30 FPS and you get 82 944 000 bytes. That would make many ordinary networks and network adapters choke. You could try huffYUV (lossless) as video codec but I am not sure if any streaming method supports it.

H.264 also supports lossless encoding, but I am not sure if that can enabled with VLC.

For audio acodec=s16l and acodec=flac are lossless.

What's the steps to duplicate your problem? I can't even preview the video with BM Intensity Pro, seems that you are a bit luckier.
Normally if can preview, there is always a tweak somewhere to get the streaming working...
