I'm trying to use vlc 1.0.0-5 as audio/video streaming server, but I get a jerky video, a few frames per second. The sound is OK.
After some testing I realized that the problem lies in acquisition by the video card.
Indeed stream with transcoding a video file works fine, while viewing the TV (analog) is jerky.
The amount of cpu is negligible and v4l2 drivers are installed correctly (tvtime and mencoder OK). Even reducing the size of the frame the problem persists.
To view the television use this command line:
vlc --vout xv --input-slave=alsa://hw:1,0 v4l2:///dev/video0 --v4l2-fps=25.000 --v4l2-standard=0 --v4l2-input=0 --v4l2-width=720 --v4l2-height=576 --v4l2-fps=25 --v4l2-tuner-frequency=639250 --v4l2-tuner-audio-mode=1To remove the doubt that the system is unable to support the operations of acquisition-transcoding-stream, I tried the following chain: acquisition and encoding with mencoder which writes a file, and streaming video of this file with vlc. Result: perfect audio and video, low cpu load.
I would then come to the conclusion that vlc is unusable (at least currently) to stream live video.
The question is: is there any software for things to do streaming video?
Thanks to those who want to answer.

There are other streaming servers, but what about ffmpeg - did you try it? You can read the source with ffmpeg and forward it to ffserver (part of ffmpeg). Check the manual pages for both.
You need to install an RTFM interface.

I have already made an attempt with ffmpeg, but I was not able to properly configure ffmpeg to capture live audio and video. Any suggestions?
