RAW Image access at Objective-c level

[timeinpixels]

Hello,

What would be the best way to access the image data at Objective-c level? Our codebase is in c++ and obj-c and I was wondering how should I go about implementing it properly.

Any hints would be greatly appreciated.

Hi,

The SDK doesn’t currently offer this kind of access. Can you describe your use case in more detail and explain why you need the image data?

Perhaps your use case is already covered or will be covered by future additions to the SDK on our roadmap.

We would like to create an image analysis tool (port our existing desktop app). It heavily uses metal shaders for rendering and computation so ideally we would like to get each frame as Metal texture (or GPU buffer, IOSurface, etc).

Currently, the closest you can get to the image is by adding a CIFilter using the filters property of VideoViewController or VideoView. From there, you may be able to take the inputImage your filter receives and render it into a texture or buffer.

We’ll think about your use case and we’ll get back to you.

Thank you. I will try that. Need to figure out the proper way of bridging swift to Objective-C, but should be possible.
