m4a reported as 3:50 but only plays for 2:17

Postby jgn » Fri Jun 26, 2020 1:04 am

In the regular interface, a song (an .m4a) is listed as being 3 minutes and 50 seconds.

Then when I use the built-in player, it flashes 3:50. Then it goes to 0:00 and quickly interates up, stopping at 2:17.

Other songs show the same pattern, but with different final lengths.

The track plays the full 3:50 in the MacOS Music (formerly iTunes).

The install is standard. Haven't changed the ffmpeg settings.

In short:

Track is 3:50.
After a time, it shows 2:17, and only plays for 2:17.

Ah, weird tidbit: Only Firefox. Duration is correct in Chrome and Safari.
