Worth to mention that Gurkirpal told me that it does not crash when using
vaapih264dec. So the difference here is vaapipostproc.

Gurkirpal, please try:

A:
gst-launch-1.0 videotestsrc ! "video/x-raw, format=NV12, width=1280,
height=720" ! vaapipostproc ! "video/x-raw, format=BGRx, width=1280,
height=720" ! ximagesink

B:
gst-launch-1.0 videotestsrc ! "video/x-raw, format=NV12, width=1280,
height=720" ! vaapipostproc ! "video/x-raw, format=BGRA, width=1280,
height=720" ! videoconvert ! ximagesink

C:
gst-launch-1.0 videotestsrc ! "video/x-raw, format=NV12, width=1280,
height=720" ! vaapipostproc ! "video/x-raw, format=RGBA, width=1280,
height=720" ! videoconvert ! ximagesink

D:
gst-launch-1.0 videotestsrc ! "video/x-raw, format=NV12, width=1280,
height=720" ! vaapipostproc ! "video/x-raw, format=RGBx, width=1280,
height=720" ! videoconvert ! ximagesink

E:
gst-launch-1.0 videotestsrc ! "video/x-raw, format=NV12, width=1280,
height=720" ! vaapipostproc ! "video/x-raw, format=NV12, width=640, height=480"
! videoconvert ! ximagesink

And let us know if there is one working. Thx!

This is using vaapi nouveau driver from mesa/gallium but the crash happens in
gstreamer. At first glance I would say it is a problem in vaapi nouveau because
it is not as well tested as vaapi intel driver. But since it crashes in
gstreamer it could still be a pb in gst.
