In the linked question origin/master is not a remote branch — it's local remote-tracking branch. If you don't have the branch locally you need to fetch it first:

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.

You don't get to decide what port to run on Heroku. Heroku will tell you the correct port to use via an ENV variable. You can get this and then run:

Solution-1:

Use single quotes

add vendor folder to your .gitignore. someone can use (composer install) and (composer dump-autoload) for install your dependencies to project.

Firstly you missed "AND". Secondly to make a bit nicer use "Select Case"

You're creating the variable right there. You can even name it something else if you want (eg. $update_checker), that shouldn't cause any issues in this particular case as the variable isn't being used anywhere else (according to your own words.)

For more details: PHP variables.

You have the same kind of error in sass/node-sass issue 2447, with as a solution:

I upgraded to the latest webpacker gem and the error went away

The reason why there's an infinite render loop in your code when you include the onChange handler in the effect dependencies is because when whenever the handleCheckboxChange function is called, the handleCheckboxChange function is redefined due to state.identifiers_checkbox.selected_checkboxes and state.identifiers_checkbox.options_checkbox in the dependency array since both of them are updated in the redux state every time handleCheckboxChange is called.

Then, when you pass onChange into the dependency array of the useEffect, it runs the effect every time the onChange changes which is every time handleCheckboxChange is run - hence the infinite render loop.

So, the easiest way of fixing this would be to put onChange into a ref in the child component so you don't need to include it in the dependency array, that way it remains up-to-date in the effect, and doesn't cause an infinite render loop of doom.
