Thanks for reporting. Can you add some logs for the crash? https://elementary.io/docs/code/os-dev#inspecting-crashes

I also have this problem. It's a segmentation fault.

With gdb the application plays a video without crashing (the same video that crashed it without gdb). However towards the end of the video, the app freezes. This is the output of gdb:

When the app freezes write bt. It will generate the backtrace.

[ezeveliz]

Here you have
video.log

[arshubham]

Can you reproduce it on all files or is limited to a type of files. Does it play correctly if you open files specifically in open file option on welcome view?

Edit: I am unable to reproduce it. Can you share a sample file you are experiencing crash on?

[ezeveliz]

They're all mp4 files, I realized that if I play files from the file explorer(play a movie, return to file explorer, choose another movie to play) it works fine.
If I open the video app, choose something from the inbuilt library, then go back to the library and choose something else, it dies.

[arshubham]

I am unable to reproduce your exact crash. However there is a similar issue where videos doesn't crash but doesn't play the file as well. #158

Can you test it with both Auto Queue enabled and disabled?
