Hi lmw0320,

Can you try one of the following command-lines?

ffmpeg -hwaccel cuda -i 1.mp4 -c:v h264_nvenc -b:v 4M -c:a copy output.mp4

or

ffmpeg -c:v h264_cuvid -i 1.mp4 -c:v h264_nvenc -b:v 4M -c:a copy output.mp4

Best regards,

Diego

No, found same error caused.
For I run the command by docker container. And I restart a new container with params of -e NVIDIA_DRIVER_CAPABILITIES=video,compute,utility, then the ffmpeg with gpu can be used to accelerate the transfer speed.
Thanks

Hi @lmw0320,

I see. Thank you for sharing the solution to your problem. Please keep in mind that the best transcoding performance is achieved while using the GPU for both decoding and encoding. If FFmpeg does not find a suitable hardware accelerator, it will use the CPU for decoding. That’s why I suggested to use -hwaccel cuda or -c:v h264_cuvid.

Best regards,

Diego
