on bug 98278
from Christoph Haag
I'm just a user, so take this with a grain of salt, but I found that radeon with vaapi only works with the nv12 color format and produces something broken like this with i420. The last time I tried it, vaapipostproc format=nv12 did not work, so I had to do the color space conversion on the CPU with videoconvert. Here is a pipeline that last worked for me: gst-launch-1.0 ximagesrc display-name=:0 use-damage=0 startx=0 starty=0 endx=1919 endy=1079 ! videoconvert ! video/x-raw,framerate=60/1,format=NV12 ! vaapih264enc ! h264parse ! matroskamux ! filesink location=output.avi Can't really test right now because it hangs my GPU, but I see it saves one frame that has this vertically doubled image too, with correct colors though.
