The FFmpeg package in Raspberry Pi OS is built with H264 Hardware. In that case it is exactly the same codecs and same video/audio streams, just a different container. mp4 container, no re-encoding done at all. Which for me, means that my gpu is 'NVENC capable' but I don't see what to try. ffmpeg -i yourfile.mkv -c:v copy -c:a copy yournewfile.mp4 would copy one video and one audio stream from your. ffmpeg -y -vsync 0 -hwaccel cuda -hwacceloutputformat cuda resize 1280x720 -i input.mp4 -c:a copy -c:v h264nvenc -b:v 5M output. The following command uses the built in resizer in cuvid decoder. However this command works (for h265): ffmpeg -hwaccel_device 0 -hwaccel cuda -i input.mp4 -c:v hevc_nvenc output.mp4 The following command reads file input.mp4 and transcodes it to output.mp4 with H.264 video at 720p resolution and with the same audio codec. ![]() This command line result in " No NVENC capable devices found" error: ffmpeg -hwaccel_device 0 -hwaccel cuda -i input.mp4 -c:v h264_nvenc output.mp4 ![]() I'm trying to convert a 7200x3600 60fps h265 video using my RTX 3080 to the h264 codec because of some compatibility issue with VR. ![]()
