Original commit message from CVS: Some final fixes for the v4lsrc elements. * remove software sync thread (use GST_ELEMENT_THREAD_SUGGESTED instead) * make all src elements threadsafe * fix num_buffer argument setting in v4l2src (VIDIOC_S_PARM) * re-add bufsize (RO) for v4lmjpegsrc * fix the A/V sync calculation in all elements (spvf=GST_SECOND/fps, not GST_SECOND*fps) * probably some more crap.... With all this, it actually works quite well. The TODO files describes the next steps in order to make a full-featured video recorder based on these elements and GStreamer (bottom). Making a simple recorder should be fairly easy now, btw.
