Steps to reproduce:

  1. Install the sample app on Android 10 device
  2. Grant permissions
  3. Hit "Basic Usage" button
  4. Pick any video file from the list and hit "START CODEC !!" button

Expected result:

Video file is being processed

Actual result:

Mp4Composer.Listener gets an "onFailed()" callback, because the constructor of the FilePathDataSource fails with FileNotFoundException (EACCESS (Permission denied).

Workaround:

Add android:requestLegacyExternalStorage="true" to the application tag in the manifest. See https://commonsware.com/blog/2019/06/07/death-external-storage-end-saga.html for an in-depth discussion.
