X265 slow encoding
hi, ive been doing a few encodes lately on my lab-encoder and im getting abmysal encoding speeds connected to the ffmpeg+x265 not using all the cpu capacity:
HW: Dual Intel Silver 4118 (20cores + 20HT cores), RHEL 7.7
sourcefile is a 422hq Prores file
ffmpeg is the latest gitpull from yesterday
Result: encoding at 1fps speed 0.04x
Machine has a load of 2 (40cores..??), almost all cpu cores are idle
./ffmpeg -loglevel verbose -i file_p25.mov -strict -1 -vf format=yuv420p10 -codec:v libx265 -x265-params keyint=100:min-keyint=100:no-open-gop=1 -level 4.1 -preset veryslow -crf 16 -profile:v main10 -y xtemp3_P6slow_nolimit_max.ts
Anyone know whats going on?
