I want capture with MHL cable.

Hi.

I want to capture the screen of smart phone using MHL cable.

But I don't know how to set the device.

I use DeckLink HD Extreme 3D+ and Galaxy S3.

Galaxy S3 support 1080p 30hz so i connect phone to DeckLink with MHL cable.

But any screen not appear in Media Express.

I have some question.

1. Does the DeckLink support the capture with MHL?

2. How to capture the screen of smart phone(Galaxy S3) with DeckLink?

Are you sure the Galaxy S3 will produce a 'desktop' clone (for want of a better phrase) from the MHL output (to HDMI, presumably)?
Or will it just output video from a media player application?

I succeeded in producing the 'desktop' clone from the MHL output to HDMI of Monitor which is support MHL input.

Galaxy S3 have the 720p resolution but it is support the 1080p output, even if you need HDTV Adapter.

How to do that capture the screen of phone?
