Re: [FFmpeg-user] ffmpeg command required to convert MPEG TS to HLS with transcoding to aac

Hello, 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 master.m3u8 File wich references all the tracks master.m3u8 yourself. My Script is about 3500 lines long, so be prepared that you have to

[FFmpeg-user] How to get HDR metadata inside my AV1 video?

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

@Dave Blanchard 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

Re: [FFmpeg-user] fmp4 streaming issues

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, about the first point, I have no idea, maybe somebody else has. About the audio, I'm pretty sure that TrueHD is a BlackBox to ffmpeg, same goes for Dolby Atoms. I'm not sure if you have access to a MacOS system, I personally run it inside a VM. There is a tool called "Subler" for MacOS,
