Comment (by tamc):
Sorry my original ticket wasn't clear.
Tested against current git head.
Steps to reproduce:
1. Download the attached original.mp4 (or any other h264 file with a
"rotate : 90" in its metadata
2. `ffmpeg -noautorotate -i original.mp4 -metadata:s:v rotate=0 -vf
scale=640:480,transpose=clock -f mp4 -y rotated.mp4`
3. `ffprobe -i rotated.mp4`
4. Note the (for me, unexpected) presence of `Metadata: rotate : 90` in
the output.
That metadata was not there in previous versions of ffmpeg.
Full output:
{{{
ffmpeg -noautorotate -i original.mp4 -metadata:s:v rotate=0 -vf
scale=640:480,transpose=clock -f mp4 -y rotated.mp4
