Comment:

 This one's related to framerate somehow.  After sfrate 1 15:

 `gst-launch v4l2src ! theoraenc ! oggmux ! filesink location=/tmp/foo.ogv`
 lasts two seconds regardless of how long we record for

 `gst-launch v4l2src ! jpegenc ! avimux ! filesink location=/tmp/foo.avi`
 is similar

 `gst-launch v4l2src ! 'video/x-raw-
 yuv,width=640,height=480,framerate=30000/1001', ! videorate ! queue !
 'video/x-raw-yuv,framerate=15/1' ! jpegenc ! avimux ! filesink
 location=/tmp/foo.avi` works pretty well.

 The equivalent of the final pipeline but with theoraenc instead of jpegenc
 doesn't work well, and I don't know why.  It seems that we're somehow
 failing to have gstreamer find the right framerate automatically, *and*
 furthermore theoraenc is failing in a way that mjpeg isn't..

 .. any ideas, anyone?  I wonder if there's a way to try out F12 (or F10)
 gstreamer on F11..
