Yep it seems to be more consistent if av_frame_make_writable could
support hardware frames.
Please let me know if you are going to do it, or if

Writing around in these is documented as disallowed.
You can call av_frame_is_writable() on the frame. If it returns true,
it's safe to wr

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.
Yes I see. So
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!

P.S. This is my first patch, I would be grateful for any feedback to know if

Thanks!
