It strikes me that if we could find examples of material that was available in
both Vision and other HDR formats (HLG, HDR10 etc) for which the specs are
open, a stab could be made at a reasonably

Hello,
I’m using FFmpeg as a transcoder to do some conversion on an incoming RTMP
stream (served on my own server with nginx-rtmp-module), and then publish the
result to another RTMP service. My publishing client is written in ActionScript
3.
In a graph it’s like:

It's a bit more complicated than just a twelve-bit video signal. Vision uses
the 10-bit image as a base and then trims it using the additional data stream,
taking into account the capabilities of the display.
Correct display

I opened ticket #5688, thank you for the sample!
Is there a software decoder?
Contrary to what was written, I think this would not be too
difficult if it were known what the additional nal's contain.
Maybe it can be made as a FFmpeg Google Summer of Code 2017 mentored
project.
But now I can see how much time and money it would need to develop
something that big. A dual layer decoder and HDR dynamic metadata support
has never been implemented in FFmpeg before. We would need to implement the
VES
That's a very, very big job which I suspect won't be happening without
significant amounts of financial input.

Here is the link to the Dolby Vision sample. Unfortunately, it will only
play correctly on a Dolby Vision enabled TV. Most TVs and all media players
will simply discard the enhancement layer when decoding, leaving only t

There should be options to make the encode (significantly)
faster. (Command line and complete, uncut console output
missing.)
I don't think your graphic

This command can be useful but as you found out, it is not
ideal to dump a stream from the internet.
You could test "mplayer -dumpstre

Please provide a sample.

Hi,
I've downloaded an HLS live stream with `ffmpeg -i
http://example.com/playlist.m3u8 -c copy -bsf:a aac_adtstoasc dump.mp4`. This
has worked for me before. I've been keeping the command running overnight and
today my SSD was full. I thought, no problem, just cut the file, but the file
is bro
