[BUG] m2ts was not created

[LaurentS]

What is the difference with developping for Windows, as long as you're also dependant to the bugs from tsmuxer, ffmpeg and others tools ?

Often bugs are MacOS only bugs. Like in the font issue in tsMuxeR.
Problem with that for me is that I have a hard time reporting and reproducing those bugs since I only run MacOS in a VM (without hardware accelleration).
Also:

• lots of developers do not own a Mac or even a VM running a Mac but crosscompile on a Linux system.
  
• MacOS has it's own development enviroment XCode where the from time to time change stuff that breaks compatibility with for example Qt.
  
• Not much folks on MacOS run freeware tools and report problems so you often run into bugs that have been around for ages, but nobody reported them.
  

Thanks a lot for all these explanations.
I understand you for the problems with using a VM, especially to emulate a recent macOS system, which maybe a lot cpu using.
I had to do the same myself when my mac was too old to install recent macOS. tsMuxer and other tools were too old and too buggy for my 10.11 system.
So I found the latest versions were able to work on Windows 7. That I could manage on a VM. But it was hard for my cpu: VM + video encoding for Blu-ray -> ouch!
But at least it could work on an old Windows version.
Then I could buy a 4-years old iMac and install a more recent macOS.

Apple seems to pretend to make a revolution every year with all its systems. And some good things don't work anymore.
I could install BigSur on my iMac but I really don't want to go beyond Mojave. Catalina seems to be a breaker and would make me lose more than what I would earn.

I always forget that you use an old MacOS.
Yes, Apple changed their font handling in Catalina.

Yet another reason not to go Catalina
