Support for NVENC about axiom HOT 3 CLOSED

Sure thing. I'm planning to update the interface and add more options so you can choose profile, pixel format, and filters.

from axiom.

@zakx I've upgraded the interface, now there will be more room for additional options. I will plan on adding a hardware encoding toggle under Settings that will enable h264_cuvid and h264_nvenc.

@zakx

I added a HW Accel dropdown menu under the Format Tab.
To enable it, select a format like MP4 or MKV, set Video Codec to x264 or x265.

Let me know if it works correctly. I'm not able to test it, I don't have a compiled FFmpeg that supports it.

x264 uses h264_cuvid and h264_nvenc
x265 uses hevc_cuvid and hevc_nvenc

DXVA2
ffmpeg -hwaccel dxva2 -y -i input.mp4 -c:v h264_cuvid -crf 23 output.mp4

CUVID
ffmpeg -y -i input.mp4 -c:v h264_cuvid -crf 23 output.mp4

NVENC
ffmpeg -y -i input.mp4 -c:v h264_nvenc -crf 23 output.mp4

CUVID + NVENC
ffmpeg -hwaccel cuvid -c:v h264_cuvid -y -i input.mp4 -c:v h264_nvenc -crf 23 output.mp4
