Got this Dahua vto stream link: that works with omxplayer, but vlc won't play it:
rtsp://user:pass@ipadd:554/cam/realmonitor/channel=1&subtype=1
This is the output of vlc:

Main problem is omxplayer is deprecated but it play it fine, after 10 seconds of loading. Can someone let me understand why vlc doesn't at all?
So what happened is that the library in Debian providing support for live555 was removed in February of this year, this affects all downstream distros including but not limited to RPi OS and Ubuntu:
https://askubuntu.com/a/1363113
The 2 active versions were 2020.01.19-1 and 2018.11.26-1.1, Live555 has since added GPL license headers to the offending files, however the RFC issue remains.
Now you may be tempted to just download the latest Live555 source code and compile it... it does not work. There have been changes to function names and structures referenced by VLC, and as such VLC will not compile against the source. You need to get an older version, I specifically used this one, which is a tweaked snapshot from 2020 prior to the modifications that prevent VLC compilation:
https://github.com/rgaufman/live555
The configuration you want is ./genMakefiles linux-with-shared-libraries, I do not know if it is required but since my system is x86-64-bit I added -m64 to the compiler options first
After compilation and install, I went on to compile VLC, adding '--enable-live555' and '--with-live555-tree=extras/live555-master' after placing the root Live555 folder in the VLC extras folder, however VLC failed to compile, it turns out the Live555's make install does not copy all the header files needed to where VLC is looking. They were dropped as 4 subfolders into /usr/local/include/, and the actual libs into /usr/local/lib/. Adding the correct CXX/CPP flags will make it look where they were put, however I put them all in a single folder and used 1 flag.
I also had to '--disable-mod' to work around a dependency version issue that I had no interest in fixing, since I do not use modplug or any mod files.
50 minutes later... VLC successfully compiled! However it was expecting the libraries for Live555 to be in /usr/lib/ not /usr/local/lib/, since it took so long to compile I was just fine with linking or copying the libraries into the expected folder, and after that VLC works with RTSP when linked to the new file. Or you can choose to maintain the original VLC and run the new file directly if you need to load the camera feeds.
