Not exactly sure how it works with filter_complex, but with regular filter
you would do something like:


This will grab the decoded frames from GPU memory, convert to nv12 (from
cuda format), then apply whatever filter you need, change the format to
something reasonable (my example uses yuv420p, then upload frames back to
GPU memory

Hope that helps,
