Bug ID: 419954
Summary: HW acceleration (VAAPI) not available in Appimage
Product: kdenlive
Version: 19.12.3
Platform: Appimage
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Video Display & Export
Assignee: j...@kdenlive.org
Reporter: ad...@djfun.de
Target Milestone: ---
When using the Appimage version of kdenlive (I tested 19.12.3 and 20.04-rc2) HW
acceleration (VAAPI) is not available.
STEPS TO REPRODUCE
Settings -> Run Config Wizard -> Check hardware acceleration
OBSERVED RESULT
"No hardware encoders found."
Terminal output is:
// FFMPEG ARGS: ("-hide_banner", "-y", "-vaapi_device", "/dev/dri/renderD128",
"-f", "lavfi", "-i", "smptebars=duration=5:size=1280x720:rate=25", "-vf",
"format=nv12,hwupload", "-c:v", "h264_vaapi", "-an", "-f", "mp4",
"/tmp/KpfdjT.mp4")
/// ++ VAAPI FAILED ::::::
EXPECTED RESULT
HW acceleration works like when I use the version from the Ubuntu repository.
It seems that the ffmpeg version in the Appimage doesn't recognize the
"vaapi_device" option (the ffmpeg in /usr/bin/ does):
» /usr/bin/ffmpeg -hide_banner -vaapi_device /dev/dri/renderD128
Hyper fast Audio and Video encoder
usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options]
outfile}...
Use -h to get full help or, even better, run 'man ffmpeg'
» /tmp/.mount_kdenli0yi7bI/usr/bin/ffmpeg -hide_banner -vaapi_device
/dev/dri/renderD128
Unrecognized option 'vaapi_device'.
Error splitting the argument list: Option not found
