Output of encoder to cuda frame format

Open FCLC opened this issue 4 years ago • 2 comments

Partially a feature request- ability to decode the frame to an ffmpeg cuda frame so that it can be used in conjunction with cuda HW filters directly, instead of going back and fourth between cpu and gpu context. As of now we end up doing 6 copies of memory structure's over the PCIe bus, instead of 2 if we kept everything in the GPU context with cuda frames.

@FCLC Hi. This might be a stupid question, but is it possible to use scale_cuda filter with this jetson-ffmpeg?

I'm the wrong person to ask, I've also not worked on this in a few months time. If you have the hardware, best to test and report back so it can be documented.
