Description
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.
