16fdb48e0d avcodec/nvenc: handle frame durations and AV_CODEC_CAP_ENCODER_REORDERED_OPAQUE 2023-06-16 22:10:42 +02:00
Timo Rothenpieler
6c418ae25e Revert "lavc/nvenc: handle frame durations and AV_CODEC_CAP_ENCODER_REORDERED_OPAQUE" 
The implementation is flawed in that the frame opaque data is not in
fact correctly reordered along with the packets, but is being output in
packet input order, just like the dts are.

This reverts commit 3553809703.

73a2252f1d avfilter/vf_bwdif_cuda: CUDA accelerated bwdif deinterlacer 
I've been sitting on this for 3 1/2 years now(!), and I finally got
around to fixing the loose ends and convincing myself that it was
correct. It follows the same basic structure as yadif_cuda, including
leaving out the edge handling, to avoid expensive branching.
