Public bug reported:
The ffmpeg version distributed via apt on Ubuntu 20.04 LTS cannot
correctly decode AAC audio in MP4 container when the file is generated
by iOS.
The ffmpeg version on Ubuntu 18.04 LTS results in correct parsing.
Here's working version from Ubuntu 18.04 LTS:
$ apt policy ffmpeg
ffmpeg:
Installed: 7:3.4.8-0ubuntu0.2
Candidate: 7:3.4.8-0ubuntu0.2
Version table:

Here's not-working version from Ubuntu 20.04 LTS:
$ apt policy ffmpeg
ffmpeg:
Installed: 7:4.2.4-1ubuntu0.1
Candidate: 7:4.2.4-1ubuntu0.1
Version table:
*** 7:4.2.4-1ubuntu0.1 500

The ffmpeg version distributed via snap does parse the file correctly
but snap version is much slower than the version distributed via apt so
I'd much prefer using the apt version if it worked correctly.
