Firefox plays all videos from YouTube, Twitter, facebook and etc.....but with error message

hi

Firefox plays all videos from YouTube, Twitter, facebook and etc…but with error message when opened by terminal or application icon. Is there any correction that needs to be made?

That comes from this code:

and it’s caused by:

https://github.com/MPEGGroup/FileFormat/issues/35

so it’s caused by the clip you play as it may contain some wrong data. But Firefox may not throw that info to terminal.
