[FFmpeg-user] ffmpeg with vulkan and or opencl

[owen s]

Hi Carl

I built ffmpeg from git:
https://gist.github.com/teamblubee/21937f6b606c6577f8c2a40da76d64e5

here's the output from ffmpeg:

Use -h to get full help or, even better, run 'man ffmpeg'


ffmpeg-git -hide_banner -hwaccels
Hardware acceleration methods:
vdpau
vaapi
drm
opencl

trying to run this command
ffmpeg-git -y \
-loglevel debug \
-hwaccel vaapi -hwaccel_device /dev/dri/renderD128 \
-loop 1 -r 4.8 -i ./image.jpg \
-stream_loop -1 -i ./audio.mp3 \
-c:v h264_vaapi -pix_fmt vaapi_vld \
-b:a 128k -ar 44100 -ac 2 -acodec aac \
-r 30 -g 60  \
-f flv /dev/null

I get this error: http://0x0.st/-i1t.txt

How can I actually use any of these hardware accelerated options?
