When using UYVY format as the input for jpeg encode, the output file show noise. (This need the patch #615 )

cmdline: $ gst-launch-1.0 videotestsrc num-buffers=1 ! video/x-raw,format=UYVY ! vaapijpegenc ! jpegparse ! filesink location=out.uyvy.jpeg

And I used jpegenc from libva-utils got the same result: $ jpegenc 320 240 in.uyvy out.jpeg 2 50

Ps, when using YUY2, the output looks good.

Noise picture: out

Expected picture: gst yuy2

I tried the command with #615 in EHL Simics, can see this issue. it fails with UYVY, but looks good when tried with YUY2.
