FFMpeg v2.7 auto rotation feature breaks scaling

[sujayjaju]

Starting v2.7 FFmpeg automatically rotates videos based on metadata
So if a rotated video is converted using a resize filter, the aspect ratio gets inverted.

Please let me know if more information is required on this.

@sujayjaju Docs in FFmpeg documenting this automatic rotate? Has FFmpeg a flag/option to disable it?

[sujayjaju]

Under change log: https://raw.githubusercontent.com/FFmpeg/FFmpeg/master/Changelog it says:
version 2.7:
...

• Automatically rotate videos based on metadata in ffmpeg
  ...

Thats the only documentation I found.

There is a "-noautorotate" option to disable it.

There is a "-noautorotate" option to disable it.
Thanks, this should be automatically incorporated, depending if the installed ffmpeg supports it to keep BC and maybe a autorotate filter or similar if autorotate is really needed..

[tengotengo]

was it ever fixed?

It doesn't seem so. @tengotengo Could you please send me any file you can reproduce with(preferably Public Domain)?

It is possible to disable the autorotation with this library already without changes.
As mentioned in the README, it is possible, to add custom parameters.
In this case, the following snippet will disable the autorotation:

$format = new FFMpeg\Format\Video\X264();
$format->setInitialParameters(array('-noautorotate'));
$video->save($format, 'video.avi');
