I tried using hardware video encoding with amdgpu/vaapi, but every attempt immediately crashes the system. The latest command line (amongst many with the same crash result) I tried: ffmpeg -vaapi_device /dev/dri/renderD128 -t 10 -i somevideo.mp4 -vf 'scale=1920:1072,hwupload' -aspect 1920:1072 -map 0:0 -y -c:a copy -threads 1 -slices 1 -vcodec h264_vaapi -b:v 12500k -profile:v 77 -bf 0 test.mkv ffmpeg/libva/mesa/dri etc. are the most recent ones currently shipped with Arch Linux (ffmpeg version 3.3.3 built with gcc 7.1.1). I am currently using https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-drm-next as my kernel, but experienced the same error also with previous kernel versions (like 4.12) Video card is a Radeon RX 460.
Please attach the output of dmesg and vainfo.

Does it help if you set the env VAAPI_DISABLE_INTERLACE=1 and modify the -vf to look like -vf 'scale=1920:1072,format=nv12|vaapi,hwupload' Without those I don't crash on R9 285, but the result would be junk - so worth using! 1072 is a strange height to use though it doesn't hurt my setup.
(In reply to Andy Furniss from comment #3) > Does it help if you set the env > > VAAPI_DISABLE_INTERLACE=1 Yes! I wonder how "interlace" is still a thing so many years after CRTs became obsolete, and no interlaced videos were ever involved in my attempts, but whatever this variable does, it changed the hardware encoding experience for me from "crashes all the time" to "does not crash and even produces a proper video in about 50% of invocations". Weirdly, about half of the times I start the very same ffmpeg command line for the very same input file, the output video shows mixed up positions of frames, as in "not frames 1-2-3-4-5-6 but e.g. 1-4-2-3-5-6 shown in sequence". > and modify the -vf to look like > > -vf 'scale=1920:1072,format=nv12|vaapi,hwupload' Works for me as well as my original command line. > 1072 is a strange height to use though it doesn't hurt my setup. At one point in time, I got error messages from ffmpeg that the encoder was incompatible with sizes that are not even multiples of 16 - that's why I introduced this scaling just for testing. But this scaling is not relevant anymore, works the same now with or without it. I think we can close this bug report: While the distorted-frame-sequence-half-the-times symptom is unpleasant, it's quite different from "crashing all the time". And now that I experienced that h.264 hardware encoding on an RX 460 (in 4k) does not even reach realtime speed, it seems to me that I should probably stick to "x264 -preset ultrafast" for live streaming anyway.
VCE does seen to have suffered some regressions recently - I stopped testing it in March due to one in mesa that broke my normal testing. It's possible that gstreamer regressed and the mesa commit just exposed its deficiencies. Whatever the reason there are more issues now and I don't know what caused them or when they started due to ignoring VCE for so long. ffmpeg was OK last time I tried - but it clearly isn't for you. On the 4K speed - even when everything was working perfectly ffmpeg always was half the speed of gstreamer for me. I could in a very artificial test get 4K60p encode with gstreamer (pre-prepared raw nv12 video in ram). Getting that speed in other circumstances gets tricky as CPU bottlenecks get involved for things like making the nv12 from other formats to feed the encoder.
