 Summary of the bug:

 I've been using ffmpeg 5.1.1 to convert open exr file sequences and audio
 wav files to prores movs. We were trying to update to 7.0.2 to deal with
 the issue where ffmpeg generated prores movs would sometimes not decode on
 apple silicon macs. However we noticed the files being output were longer
 than they should be which seems to be due to using apad and shortest and
 ffmpeg generating random length audio streams in the resulting mov. I've
 also tested with static builds of git master on windows and linux.

 Possibly related to defect #11061
