currently, i use this, however, i am unable to run it specifying points in
curves. Is any option to use a gnuplot file directly? or to extract
smplayer optiotns on brightenss, gamma etc. to use them with ffmpeg
somehow?
for vids in *.avi; do ffmpeg -hwaccel vaapi -hwaccel_output_format
yuv420p -vaapi_device /dev/dri/renderD128 -i "$vids" -vf
'curves=preset=lighter,setpts=2*PTS,format=nv12,hwupload,scale_vaapi=w=2560:h=1440:format=nv12'
-strict experimental -c:v hevc_vaapi -b:v 20M -video_track_timescale
90000 "a_${vids/.*}.mp4"; done;
debian trixie linux,
ffmpeg version 7.0.2-3
