VLC does not open 2nd, 3rd, 4th, ... movie when double-clicking the movie
I'm have Linux Mint 20 (ulyana), x86_64, fully patched. The machine has been through a upgrade and dist-upgrade. The machine has 3.0.9.2-1 installed.
VLC is the default media player. I copied two DVDs to my hard drive. The first movie is THE_PATRIOT.mov. The second movie is THE_NATURAL.mov.
I double click THE_PATRIOT.mov the media player opens and plays the movie. Everything is OK. Next I close the player by clicking 'X' in the upper right hand corner of the window.
Next, I double click THE_NATURAL.mov. The media player fails to open and play the movie. I'm not sure where the failure is, but there is no error displayed to me.
I find if I perform a ps -A | grep vlc
and then kill -9 <pid>
the VLC player will start working again. I also find if I choose Media->Quit the media player does exit, and the VLC player will start working again.
I noticed there's a Tools->Preference setting about minimizing the player in Interface->Main Interface->Qt. Unchecking "Systray icon" does not help. The same behavior is present.
The bigger problem I have is, the machine is for my parents. They are getting off Windows. They don't know how to use the Linux command line. They are barely qualified to use Linux, and that's why they are getting a Linux-on-Training-Wheels via Linux Mint.
The ps/grep/kill chain is too complicated for them. And I probably won't be able to break their habit of clicking "X" to close an app. They spent years learning it, and they probably won't be able to unlearn it for this one program.
It would be incredibly helpful for beginners if clicking the "X" button actually closed the media player. That way, the media player is ready for the next movie.
If you can't fix the "X" button, then please consider fixing the communication problem that's getting in the way of opening the 2nd, 3rd, 4th, ... movie when a user double clicks on a movie.
Finally, the issue may be present when clicking on songs in the Music folder. I did not test it.
