Hi

is it possible to have the complete decoding and encoding done on the
GPU instead on the CPU?

I found various examples for Kdenlive encoding with my nvidia gpu with
this command:

"f=mp4 vcodec=nvenc_h264 global_quality=21 vq=21 preset=slow bf=2 ab=384k"

but this obviously only uses the gpu for encoding while decoding is
still performed on the cpu.

I can do the transcoding both on gpu with ffmpeg and this command line:

"ffmpeg -hwaccel cuvid -c:v h264_cuvid -i input.MP4 -c:v h264_nvenc
-pixel_format yuv420p -preset default output.mp4"

which works very well, is this doable with mlt/kdenlive?

greets
Paul
