Hi all
Gstreamer version: 1.14.2
My problem:
test-launch program from gst-rtsp-server-1.14.2
$ GST_DEBUG=2 ./test-launch "( v4l2src !
video/x-raw,format=YUY2,width=640,height=480 ! videoconvert !

stream ready at <a class="moz-txt-link-freetext" href="rtsp://127.0.0.1:8554/test">rtsp://127.0.0.1:8554/test

I searched in gst-plugins-ugly-1.14.2: ext/x264/gstx264enc.c:
https://cgit.freedesktop.org/gstreamer/gst-plugins-ugly/tree/ext/x264/gstx264enc.c?h=1.14#n2282
The encoder's peer_profile was set as 'baseline' according to [
GstVideoCodecState * state ] from the previous element.
and in x264 source code:
https://github.com/mirror/x264/blob/master/common/base.c#L721
The x264 compare the profile and i_csp, found missing pair,
so give the "x264 [error]: baseline profile doesn't support
4:2:2"
I was strange if the device give the missing pair from
v4l2src element?
