Oh, I didn't noticed that h264_cuvid is legacy.
It seems the problem in this line:
ret = av_frame_make_writable(input_main);
If removed, it starts to work with -hwaccel cuda.
I'll take a closed look why and what happens but any advice would be
helpful. Thanks!
For what I'm aware, make_writable does not work on hardware frames.
And the nvdec hwaccel returns frames that are mapped device memory, and
thus hard read-only.
You will need to manually allocate output frames from the hw_frames_ctx.
