[Live-devel] stream webcam using ffmpeg and live555

[John Q]

Hi Ross,

That's what I thought too. The "testOnDemandRTSPServer" prints "missing sync byte" on the console when I try to grab frames from it using VLC.

I want to stream my webcam from a windows 7 (64-bit) machine behind home LAN using ffmpeg as the encoder to a live555 server running on a Debian 64-bit linux machine in a data center over the WAN. I want to send a H.264 RTP/UDP stream from ffmpeg and the "testOnDemandRTSPServer" should send out RTSP streams to clients that connect to it.

>But I get nothing in VLC.Are you sure that UDP packets from your "ffmpeg" computer are reaching your "testOnDemandRTSPServer" computer?  Perhaps there's a firewall somewhere inbetween that's blocking UDP packets?  That's the first thing that you should check.
