[FFmpeg-devel] [PATCH v3] 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. Signed-off-by: Philip Langdale

[FFmpeg-devel] [PATCH] avfilter/vf_yadif_cuda: remove unnecessary private struct fields

I'm not sure why I originally did this, but there's no good reason to put pointers to the cuda context and stream in the priv struct. They are directly available in the device context that is already being stored there. Signed-off-by: Philip Langdale --- libavfilter/vf_yadif_cuda.c | 12

Re: [FFmpeg-devel] [PATCH] avformat/avcodec: Add DTS-UHD demuxer and parser, movenc support.

Hi, I updated the libavcodec patch per Paul Mahol's reviews: dtsuhd_common.c:496 get_bits_long instead of get_bits used for reading 36 bits dtsuhd_common.c:224 get_bits_var changed to accept arrays in VarBits structure, allowing arrays with all values less than 256 to use uint8_t arrays. Also
