On a Toshiba Encore tablet (Win 8.1), using ImageEn 5.1 Media Foundation.

When the tablet is in landscape orientation, the camera is fine.

When the tablet is in portrait orientation, the image is rotated 90 degrees (basically unusable).

As a comparison the Windows camera app shows the image correctly in both landscape and portrait orientations.

I have tried rotating the image in the TImageEnView.MediaFoundationNotify event using TImageEnView.IEBitMap.Rotate(-90) but this is way too slow. Yes it works on a desktop pc but not ion the reduced processing power of a tablet.

Media Foundation has some functionality which looks like what is needed (IMFVideoProcessorControl.SetRotation) but this is not encapsulated by TImageEnView.

What is the solution please.

Hi

We have not yet implemented rotation of captured video frames, but it is something we are working on.

Hello

Where do we stand with the functionality to rotate a captured video file? Will this include the ability to rotate *.mov files obtained from an IPhone?

TIA

Hi John

I'm afraid, this has not yet been implemented.

Is this available now? (rotate .mov file)

Also, related, when I try to get a thumbnail for a MOV file using ImageEnView.IO.LoadThumbnailFromExplorer the thumbnail is rotated 180. It is correct in Windows Explorer.

Any suggestions?

Thanks,
Tony

Hi Tony

MOV rotation has not been implemented.

I'm not sure why Explorer will rotate a thumbnail automatically. Perhaps it uses the MOV meta-data to determine it needs rotation. ImageEn is simply returning the thumbnail that Explorer supplies it, so it has not idea whether rotation is needed or not.
