> ISOBMFF does not allow AudioSampleEntryV1 in stsd version 0, so
> assume the descriptor format is QTFF SoundDescriptionV1. ISOBMFF does
> not define a version 2.
> This fixes audio decoding for some MP4 files generated with Apple
> tools. The additional fields present in SoundDescriptionV1/V2 need to
> be read in order to correctly read additional boxes that contain
> information required for decoding the stream.

Please mention ticket #7376 (and the Handbrake issue) in the commit

Thank you, Carl Eugen
