Description raynald.lim 2015-01-29 08:44:42 UTC 
Using the below gst command:

gst-launch-1.0 filesrc location=/home/raynald/BMW/bmw_rename.mp4 ! qtdemux ! vaapidecode ! vaapipostproc "deinterlace-mode=1" "deinterlace-method=4" ! "video/x-raw, format=NV12" ! multifilesink location=bmw%d.nv12

We notice a strange greenish hue on every raw NV12 output at the bottom of the screen.

NOTE: Link to test stream has been sent to HaiHao

Comment 2 Adrian Cox 2015-05-18 11:41:52 UTC 
I have a likely related case:

 gst-launch-1.0 videotestsrc ! \
    video/x-raw,format=I420,framerate=25/1,width=1024,height=1080,interlaced=true  ! \
    vaapipostproc deinterlace-method=3 deinterlace-mode=1 ! \
    vaapisink fullscreen=true

This produces a green line at the bottom of the image.

The green line goes away if I use a smaller frame size (height = 576), revert to a simple deinterlace method (bob or weave), or use videobox to add a black border which I remove at display time.

For balance: reasons that I may be seeing a different bug. My case occurs on Haswell, and my green only occurs on frames produced by software decode. When I use vaapidecode as the frame source, the green line disappears.

You issue should be gst-vaapi related.

This isn't driver issue and we won't fix/workaround it in the driver.
