ffmpeg can do this, at least some parts. It will create the segments and a
master.m3u8 file for each track by itself. Still you will need to create

Hey folks,
I'm trying to reencode a 10 Bit HEVC to 10 Bit AV1 while keeping the HDR
metadata intact.
Sadly, I don't see any HDR metadata with VLC at the reencoded AV1 clip.
The only thing I see are very cold looking colors, have a look at my
encode command:
/usr/bin/ffmpeg -i

Hello again,
I've now applied the patch you provided, it worked without a problem.
Sadly, this was not the root-cause in the end.
The stream still often breaks on quality change using VideoJS 7.20.3
with fmp4.
I also tried to only use one single video and audio codec at my hls
Hello,
thanks for your time.
Well, I would love to use a single way of transportation. Currently, I
have to work with HLS and DASH side by side ...
SRT is not wanted at the moment. We have our own build script that also
builds all libs from source incl. svt-av1 which we heavily rely on.
Hello,
can somebody explain why fmp4 currently does randomly break on seek
and/or quality change using VideoJS and other players, while mpegts
works 100% fine?
I really don't change anything on my encode command, except of the
output format transport type:

Thanks for your reply, Moritz,
I now came to the following cmd:

{stream["height"]} and {stream["width"]} are just placeholders

Can I use ffmpeg to convert a 1920x800 resolution clip to 1920x1080? The
goal is to fill the remaining pixels with a true black bar.

is it maybe possible that we add compatibility for more subtitle related

This looks like escaping of a character that has a meaning in the
surrounding langua
, but the "synopsis" field is still as shown above (as it was
already before switching to a different terminal.)
That would mean in conclusion that my Terminal might not by responsible
