How to compress videos on AMD RX 7900 XTX with ffmpeg ? [closed]
19 novembre 2024, par cprnOn Nvidia's GTX 1070 I used to do the below command, and it'd produce a way smaller file (often less than half of the original) without any visible degradation (at least for my eyes) :


ffmpeg -hwaccel cuda -i file.mp4 -c:v hevc_nvenc -crf 20 file.small.mp4



Now I switched to AMD's RX 7900 XTX and this command obviously doesn't work.


What's the "equivalent" of that command ? As in : getting way smaller file with seemingly no quality loss.


What I tried :


- 

av1_nvenc
ends up in errors :




ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i file.mp4 -c:v av1_nvenc file.small.mp4



Impossible to convert between the formats supported by the filter 'Parsed_null_0' and the filter 'auto_scale_0'
[vf#0:0 @ 0x60f7c1aa7d80] Error reinitializing filters!

[vf#0:0 @ 0x60f7c1aa7d80] Terminating thread with return code -38 (Function not implemented)

[out#0/mp4 @ 0x60f7c1b0d680] Nothing was written into output file, because at least one of its streams received no packets.



- 

hevc_vaapi
goes through the encoding, but produces 20% bigger files instead of smaller :




ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i file.mp4 -c:v hevc_vaapi file.small.mp4



No idea what I'm doing. I know next to nothing about video encoding, just what I read in the documentation, and I'm stuck. Also, I'm on Linux, but this shouldn't matter, I think.
