Summary of the bug: For some mp4 uploads from native android apps
(probably using a weird and/or broken encoder), ffmpeg interprets the
rotation differently from Chrome/Quicktime and autorotates the video
incorrectly, despite the rotation/display matrix appearing correct via
ffprobe.
How to reproduce:
Given video in this unusual format (attached) with rotation = 90
ffmpeg -i upsidedown-original.mp4 -y upsidedown-out.mp4
Upside down video results with rotation = 0
Patches should be submitted to the ffmpeg-devel mailing list and not this
bug tracker.
