Video with rotation metadata is stretched

[cvn]

Hello all,

I'm processing some vertical videos shot on an iPhone. With moviepy 0.2.3.2 and this code:

with VideoFileClip("ficus_vertical.mp4") as clip:
    clip.write_videofile('output.mp4')

I get this output	I expected this

Source file: ficus_vertical.mp4

The problem is that ffmpeg is autorotating the video according to the metadata, but moviepy is sizing it to the pre-rotated frame size. This problem is also mentioned by #577. Autorotate has been enabled by default since ffmpeg 2.7.

I have a branch that fixes the issue, and also allows for autorotate to be disabled. I will submit a PR after my test media is added to the moviepy_media repo.

There is a workaround described here:

Thanks, @pkarp0. I hope the issue will be fixed soon, whether by my PR or another means, but the workarounds are useful in the meantime.

@cvn Awesome. Perhaps you could take a look at my issue next:
