Just test hardware filter with cuda.
Tip: You must decode a frame , than you can get a non-nil hw_frame_ctx from decodeCtx

Thanks a lot for the PR!

Unfortunately, following this comment, I was already working on adding the proper methods to allow using hardware filtering with go-astiav 😱

Could you check out the hardware-filtering branch and let me know whether the new hardware_decoding_filtering works properly? And if new methods work properly with your workflow?

[oldma3095]

it can work by hardware-filtering branch.
cuda -> decode h264_cuvid -> encode h264_nvenc
vaapi -> decode h264 -> encode h264_vaapi
i will close this PR.

Did you also have time to test the hardware_decoding_filtering example?

FYI I've merged the hardware-filtering branch in master 👍
