Body
I'm having a problem trying to record audio+video from my webcam to a file. If I use <code>videotestsrc</code> and <code>autoaudiosrc</code> I get everything right (read as in I get a file with audio recorded from the webcam's mic, and test-video image), but as soon as I replace <code>videotestsrc</code> with <code>v4l2src</code> (or <code>autovideosrc</code>) I get <code>Error starting streaming on device '/dev/video0'</code>. The command I'm using: <code>gst-launch-0.10 videotestsrc ! queue ! ffmpegcolorspace! theoraenc ! queue ! oggmux name=mux autoaudiosrc ! queue ! audioconvert ! vorbisenc ! queue ! mux. mux. ! queue ! filesink location = test.ogg</code> Why is that happening? What am I doing wrong? EDIT: In fact, something as simple as <code>gst-launch-0.10 autovideosrc ! autovideosink autoaudiosrc ! autoaudiosink</code> is failing with the same error <code>(Error starting streaming on device '/dev/video0')</code> Replacing <code>autovideosrc</code> with <code>videotestsrc</code> gives me test image + real audio. Replacing <code>autoauidosrc</code> with <code>audiotestsrc</code> gives me real image + test audio. I'm starting to think that this is some kind of limitation of my webcam. Is that possible?
