libavformat/libsr
When scaling a 10bit video using scale_cuda filter (witch uses pixel format
AV_PIX_FMT_P010LE), the output video gets distorted.
I think it has something to do with the differences in processing between
cuda_sdk and ffnvcodec with cuda_nvcc
(the problem appears after this commit
AVHWFramesContext has aligned width and height.
When initializing a new AVFrame, it receives these aligned values (in
av_hwframe_get_buffer), which leads to incorrect scaling.
The resulting frames are cropped either horizontally or vertically.
As a fix we can overwrite the dimensions to original
There are 2 types of problems when using adaptive deinterlace with cuvid:
1. Sometimes, in the middle of transcoding, cuvid outputs frames with visible
horizontal lines (as though weave deinterlace method was chosen);
2. Occasionally, on scene changes, cuvid outputs a wrong frame, which should

This patch adds two floating-point gray formats to use them in sr filter for
conversion with libswscale. I added conversion from uint gray to float and
backwards in swscale_unscaled.c, that is enough for sr filter. But for
proper format addition, should I add anything else?

Hello,
These patches address several raised concerns regarding sr filter
and DNN module. I included three patches, that I've already sent,
but they still have not been reviewed properly.
libavfilter: Adds on the fly generation of default DNN models for
tensorflow backend instead of storing
This patch removes conversions, declared inside the sr filter, and uses
libswscale inside
the filter to perform them for only Y channel of input. The sr filter still has
uint
formats as input, as it does not use chroma channels in models and these
channels are
upscaled using libswscale, float

As far as I can see FFmpeg currently doesn't set AVStream::id for
matroska/webm streams. I think we could use either MatroskaTrack::num
(TrackNumber) or MatroskaTrack::uid (TrackUID) for that.
I have found a few discussions claiming that TrackUID could be missing,
even though TrackUID is marked as
Hello.
Recently I used ffmpeg to embed subtitles, and I needed to scale them.
I thought original_size option scales subtitles, but it does not.
So I wrote a short patch for it to do that (attached)
If that is considered too complex/bad idea I've also attached another patch
that adds a
