According to http://gstreamer.freedesktop.org/documentation/plugins.htmlv4l2src and v4lsrc should be used with raw frames. According to dmesg I'm using yuv420 output format, and I can not find useful source for it on gstreamer. Any ideas? Probably I can change the format of my cam, but that will hurt the quality of the video.
autovideosrc does not work neither What am I doing wrong?
