MediaConvert - Rotate option "Auto" does not work

[MondQ]

Describe the bug

When supplying the rotate option auto using the .NET SDK no rotation is applied. If I use the AWS console to process the same file and specify the "Auto" rotation option my video is in the correct orientation.

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

My portrait video is still in portrait orientation after conversion with MediaConvert.

Current Behavior

My portrait video is sideways after conversion.

Reproduction Steps

Specify the Rotate property on the VideoSelector class as InputRotate.AUTO.

Input input = new Input
{
    FileInput = s3InputFilePath,
    VideoSelector = new VideoSelector()
    {
        Rotate = InputRotate.AUTO
    }
};

Possible Solution

No response

Additional Information/Context

When I go to the console and check the JSON of the job that was triggered via the SDK the 'Rotate' property is not listed.

AWS .NET SDK and/or Package version used

AWSSDK.MediaConvert 3.7.409.3

Targeted .NET Platform

.NET 8

Operating System and version

Per VideoSelectorMarshaller, rotate property is set if the request field is not null. AWSSDK.MediaConvert package is auto-generated from service models and simply translates user's request to invoke a service API operation. So as such, this doesn't appear to be AWS .NET SDK issue.

Using example at Use CreateJob with an AWS SDK or CLI (code repository) and setting Rotate as InputRotate.AUTO at:

...
input.VideoSelector = new VideoSelector
{
    ColorSpace = ColorSpace.FOLLOW,
    Rotate = InputRotate.AUTO
};
...

marshalls request into below JSON:

Notice:

                    "rotate": "AUTO"
                }

From AWS Console, clicking on View JSON option for the job shows Rotate setting:

@MondQ Good afternoon. This doesn't appear to be SDK issue. SDK is creating job with proper rotate setting in input JSON. This setting is retained when viewed from AWS Console. If you refer service API documentation for InputRotate, it states that The rotation must be within one degree of 90, 180, or 270 degrees. If the rotation metadata specifies any other rotation, the service will default to no rotation. By default, the service does no rotation, even if your input video has rotation metadata. The service doesn't pass through rotation metadata.. Hence, this explains the behavior that you are noticing for your use case.

Thanks,
Ashish

I can confirm that everything works as expected and this was user error. I accidentally overwrote the video selector containing the rotate instruction.

Thank you for your time.
