[FFmpeg-user] Encode in "intra-only"

[Mohammed Bey Ahmed Khernache]

Hello,
how to encode a video sequence into hevc with "intra-only" mode using ffmpg?
I tried the following command but it seems not working:
ffmpeg.exe -f rawvideo -vcodec rawvideo -s 1920x1080 -r 25 -pix_fmt yuv420p
-frame_type if -i pedestrian_area_375.yuv -c:v libx265 -x265-params
frame-threads=4:keyint=1:ref=1:no-open-gop=1:weightp=0:weightb=0:rc-lookahead=0:bframes=0:scenecut=0:b-adapt=0:repeat-headers=1:no-strong-intra-smoothing=1
-g 0  pedestrian_area_375.mp4

Best regards
