Created attachment 127333 [details] dmesg 4.9-rc1 Happens with 4.8 and 4.9-rc1. I haven't tried 4.7. This pipeline hangs the GPU very quickly: 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 attached dmesg is from 4.9-rc1. As far as I can see, it also produces one frame corrupted output with the image being duplicated vertically and then squashed to fit into 1920x1080, see bug 98278. Probably not related to bug 97240, but maybe?
I'll mark this as invalid although it might still be worth to investigate. I took some suggestions from bug 98278 for my recording script and this is the pipeline I end up with: gst-launch-1.0 -e ximagesrc display-name=:0 use-damage=0 startx=0 starty=0 endx=1919 endy=1079 ! multiqueue ! video/x-raw,format=BGRx,framerate=60/1 ! videoconvert ! video/x-raw,format=NV12,framerate=60/1 ! multiqueue ! vaapih264enc rate-control=cqp bitrate=5000 ! video/x-h264,profile=baseline ! h264parse ! multiqueue ! matroskamux name=muxer. ! progressreport name=Rec_time ! filesink location=output.mkv This records very nicely and looks like it does NOT cause GPU hangs.
We have fixed quite a bunch of issue with VA-API as well as the kernel recently. Could be that this is fixed by now. Anyway let's close this bug for now.
