Actual Behavior

php-ffmpeg distorts video (iphone)

Expected Behavior

Hello. There is a problem with the horizontal video received from the iphone.
This is a problem for me. I now need to check every video before converting.

ffmpeg -i input.mov -vf 'scale = 320: 320: force_original_aspect_ratio = decrease' output.mp4

This works fine and I expected this behavior for php-ffmpeg, but this does not happen.

Instead, php-ffmpeg thinks this is in the AspectRatio class, instead of doing system ffmpeg.

\ Sorry for my English

Could you send us the code you are using?

Video source:
FF2KWhaOXoyp.mov.zip

require 'vendor/autoload.php';

$ffmpeg = FFMpeg\FFMpeg::create();
$video = $ffmpeg->open('video.mov');
$video->filters()
    ->resize(
        new FFMpeg\Coordinate\Dimension(600, 600),
        FFMpeg\Filters\Video\ResizeFilter::RESIZEMODE_INSET
    )
    ->synchronize();

$video
    ->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(10))
    ->save('frame.jpg'); // bad orientation
$video
    ->save(new FFMpeg\Format\Video\X264(), 'export-x264.mp4'); // bad orientation

What is happening if you replace RESIZEMODE_INSET with RESIZEMODE_SCALE_WIDTH?

[1271]

It does not change anything. The problem is not in the size of the video, but in the fact that it has the wrong orientation.

[jens1o]

But when you try to resize it to 600 x 600, it should be a square and RESIZEMODE_SCALE_WIDTH tries to further optimize it?

[1271]

The problem is not that the video will be square.
The problem is that it is rotated 90 degrees

In this case, if this video is converted using ffmpeg from the terminal, everything is fine.

try playing the video using mplayer and ffplay

I'm experiencing the same issue with vertical iPhone videos.
