For your convenient, I also dump png files from generated videos and combine
the before/after pngs into one file, see in png folder at the google drive.

btw, as a whole solution, metadata should also be generated from
the sdr video, so to be encoded as a HDR video. Not supported yet.
This patch just focuses on this paper.

Hi,
I'm trying a deep learning model with converts SDR (with format R8G8B8) to HDR
(with format R10G10B10) with ffmpeg. I wrote a video filter with only supported
format AV_PIX_FMT_RGB24 (see code below), it turns out that the format of the
input frame of the filter is R8G8B8, and so the
Did you try to build ffmpeg with TENSORFLOW_BACKEND enabled, and run it without
TF library? This case is possible when an end user install pre-built package
on a machine without TF library.
In function init, the logic is to fall back to cpu path (DNN_NATIVE) if unable
to load tensorflow
