I'm trying to stream the video and audio a USB webcam using avconv (or ffmpeg) using just port 8080 over a network.
I can successfully stream audio using the following command:
Code:
avconv -f oss -ar 8000 -ac 1 -i /dev/dsp1 -acodec mp2 -f rtp rtp://172.17.2.2:9090
and VLC will read it just fine, with maybe a 1 second delay.

Hey, I have an MSI Wind U100 laptop/openSUSE 11.2 and I'm trying to get the webcam to work. The webcam seems to be detected by the kernel as "video0" (my understanding of linux is fairly basic so I could be wrong here), but it isn't detected at all by cheese, kopete, skype, or anything else I've tried.

In the good old days of Jaunty, Ubuntu had an asound.conf file that could be patched to increase the range of audio volume. This is no longer supported in Karmic. Instead, the PulseAudio volume control allows up to a 50% increase over the norm. Unfortunately, depending on how the .avi file was created, this may not be enough.
