Video rotation metadata

I am getting this warning when reading videos from mobile phones

imageio_ffmpeg - WARNING - The frame size for reading (480, 720) is different from the source frame size (720, 480).

This means I have to rotate frames either 90º or 270º.

ffmpeg -i provides such rotation info of videos, For example:

ffmpeg -i myrotatedMOV.mov
....

Duration: 00:00:14.31, start: 0.000000, bitrate: 778 kb/s
    Stream #0:0(und): Video: h264 (Baseline) (avc1 / 0x31637661), yuv420p, 480x360, 702 kb/s, 29.98 fps, 30 tbr, 600 tbn, 1200 tbc
    Metadata:
      rotate          : 180
      creation_time   : 2013-01-09 12:47:36
      handler_name    : Core Media Data Handler
    Stream #0:1(und): Audio: aac (mp4a / 0x6134706D), 44100 Hz, mono, s16, 62 kb/s
    Metadata:
      creation_time   : 2013-01-09 12:47:36
      handler_name    : Core Media Data Handler

How can I get such information with imageio_ffmpeg? Tried get_meta_data() function but is not there

I think this can likely get closed.

As a first step, it should be possible to add code here to add the rotation info to the metadata. That way users at least have a way to deal with it.
