[FFmpeg-user] Fwd: Yadif_cuda and Pix_fmt

[Andy Sheimo]

I sent this message a couple times with zero response. Is there anyone that
can help with using NVDEC for decoding, converting 8bit to 10bit on the
GPU, then using NVENC to encode the video?

I am trying to keep the transcode completely on the GPU using CUDA to
decode then NVENC to encode, avoiding sending the data to the cpu and back
again.
