FFmpeg hevc_nvenc encoder B Frame problem

I'm using the latest FFmpeg windows Build (2022-12-02 12:44) from BtbN. I'm trying to encode a video into HEVC codec using hevc_nvenc encoder. But it says [hevc_nvenc @ 00000263983f4280] B frames as references are not supported. Cause my GPU GTX1060 (GP106) doesn't support hardware accelerate encode HEVC of B frames. command line

I tried to disable the B frames by adding the parameter -bf 0, but it doesn't work. Then I tried to use the latest build from gyan.dev and it is the same. But when I tried to use an older build (2021-02-28 12:32) of BtbN, it doesn't have the problem. Is there a workaround to bypass this B frame problem? Cause I don't want to switch to an older build. Thanks.

Solution

  • Thanks Gyan. The solution is to add parameter -b_ref_mode 0
