x265 not honoring slice config
hi, im trying to encode some hevc files for use in an ABR stack where the config is:
4 sec GOP IDR at the start on each GOP I-frames on scenecut Syntax: Code:
./ffmpeg -loglevel verbose -i test.mov -codec:v libx265 -x265-params keyint=100:min-keyint=100:no-open-gop=1:nal-hrd=VBR:force-cfr -preset fast -crf 23 -maxrate 15M -bufsize 15M -force_key_frames "expr:eq(mod(n,100),0)" -c:a:0 aac -ac:a:0 2 -ab:a:0 128k -y hevc.mp4 Code:
x265 [info]: Keyframe min / max / scenecut / bias: 25 / 250 / 40 / 5.00 Harmonic's AV analyzer tells me that x265 is actually encoding IDRs as CRA slices instead.. with some Iframes mixed in here an there.. in X264, this is all correct, but x265 this fails.. Anyone have any idea whats going on here? Last edited by TEB; 8th May 2019 at 11:34. |
