Rotation support

[rromanchuk]

Rotation support via metadata override. Backwards compatible as leaves DEGREE_0 as default, which is current behavior

This requires #23 to actually work (well, for any metadata override besides

Should also probably mention using anything but default is going to cause the profiler to possibly select the wrong encoding profile as it's pixel math will be utilizing the pre-rotated dimensions.

For example, all ios videos record portrait (without the developer normalizing) videos with ROTATE 90, if AUTO were to be selected, without overriding the JobTemplate, the profiler doesn't know what the final dimensions after rotation may be.

If you know you have 16:9 portrait videos with ROTATION 90, you will need to intervene to help profiler out

if (event.srcWidth > event.srcHeight) {
      console.log('This video is most likely going to get rotated, swap width/height')
      event.srcWidth = mediaInfo.video[0].height;
      event.srcHeight = mediaInfo.video[0].width;
 }

This is new Rotate is a new VideoSelector key, and this will fail without using the latest version of MediaConvert

Thanks for opening a pull-request ticket. We will review the requests to be implemented in our next release.

Hi @rromanchuk,

We just released a new version of the solution (v5.0.0 - https://aws.amazon.com/solutions/video-on-demand-on-aws/), and support for the InputRotate parameter has been included.

Thanks!
