Multitrack Audio Capability in the GStreamer FLV Muxer
https://centricular.com/devlog/2025-11/Multitrack-Audio-Capability-in-FLV/
For one of our recent projects, we worked on adding multitrack audio capabilities to the GStreamer FLV plugin following the Enhanced RTMP (v2) specification. All changes are now merged upstream (see MR 9682). As the name suggests, this is an ...
Finished my little tutorial as I got docker running on my 2014 macOS Ventura era iMac and then added some nginx-rtmp containers.

I'm getting closer with my nginx-rtmp-Docker-container-on-MacOS project!
I started from scratch on the mac a couple days ago, reinstalled docker with homebrew and then realized that part of my problem was that macOS (and windows) has to run docker in a virtual machine container of its own and *that* can mess with networking.
So I have now figured that out. Colima, the vm that seems most popular on macOS, needs a mac specific option (--network-attached) when starting so that it gets the mac network going. Major Aha! moment.
I also learned more completely how to build my own Docker images.
I've gotten to the point where nginx is definitely running, I know the port is open (via nmap on another device), I know nginx is accepting the stream, but nginx still refuses to publish that stream to Youtube (or at least youtube is not seeing it).
I also can ping apple.com and youtube.com from within the container, so access to the outside world is working.
I
So that's where I'm at.
I just figured out how to get into a container and examine the nginx log files now.
At this point I am going to rebuild the container with nginx configured for full debug level logging. Hopefully that provides some more clues on where it is getting stuck.
I give it a 50/50 chance that it is either an nginx configuration/installation problem or another colima virtual machine/networking issue.
I've learned a lot at least and feel better about my overall Docker knowledge!
And I'm documenting on my blog as I go so I'll have a howto produced from this when it finally works!
Still haven't figured out why I can't convince the nginx-rtmp docker container to relay my web stream. Annoying.
Anyway... in the meantime I've taken some other measures to try to take a load off #FootiMac so that my instance is more responsive (it's very laggy these days) and so I can test out the 4.5rc2 release.
Seems to be a little happier now.
Upgrade in progress. This account will likely be unavailable periodically today as I do the upgrade.
