#11480: Support or ignore Iphone16 spatial Apple apac audio
-------------------------------------+-------------------------------------
Reporter: emcodem | Type:
| enhancement
Status: new | Priority: normal

-------------------------------------+-------------------------------------
Ever since the release of Iphone 16 we get lots of transcoding errors from
these files because the apac track is being analyzed as valid audio track
but when using -map 0:a and decoding the audio, ffmpeg command fails.
Example file (consider this file GPL Licensed):
