           Summary: h264 libva capture corrupted results in rgb565 format
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: ullysses.a.eoff at intel.com
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: weston
           Product: Wayland

The libva h264 capture feature in weston generates corrupt results when output
is using rgb565 gbm-format (16bpp).  Format xrgb8888 (32bpp) works fine.

::Steps::

1. In weston.ini, set the gbm-format for the output to rgb565, for example:
 [output]
 name=HDMI1
 gbm-format=rgb565
2. Launch weston
3. Start h264 capture with: <mod>+<shift>+<space> q
4. Do stuff (i.e. launch apps, move windows, etc.)
5. Stop h264 capture with: <mod>+<shift>+<space> q
6. Playback capture.h264
 $ gst-play-1.0 capture.h264
 or
 $ gst-launch-1.0 filesrc location=capture.h264 \
   ! h264parse ! vaapidecode ! vaapisink
7. Transcode capture.h264 to capture.mp4
 $ gst-launch-1.0 filesrc location=capture.h264 \
   ! h264parse ! mp4mux ! filesink location=capture.mp4
