Original commit message from CVS: This patch: 1) would provide v4l2 plugins, if only the CVS server wouldn't bork on all commits :-(. This patch will come later on in a separate commit when SF fixes her repository. 2) it fixes capsnego for all the video4linux1 plugins 3) it rewrites the debugging of all v4l1 plugins, which now make use of the standard gstreamer debugging features (gst-mask=...). This should make debugging video4linux1/gstreamer problems much easier then it used to be. VS: ----------------------------------------------------------------------
