Bug#966059: ffmpeg: Please enable zscale filter
Package: ffmpeg
Version: 7:4.3-3+b1
Severity: wishlist
To convert a HDR video to a non-HDR one, you need the zscale filter, but
it's not available/enabled in the Debian build of ffmpeg.
Hereby the request to enable it.
ffmpeg -i "input.mkv" -map 0:v -map 0:a? -map 0:s? -c:s copy -c:a copy -vf zscale=t=linear:npl=100,format=gbrpf32le,zscale=p=bt709,tonemap=tonemap=hable:desat=0,zscale=t=bt709:m=bt709:r=tv,format=yuv420p10le -c:v libx265 -crf 22 -preset slow -max_muxing_queue_size 4096 "output.mkv"
results now in:
[AVFilterGraph @ 0x55ab18072c00] No such filter: 'zscale'
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
