Recording square video

[sethroot]

I'm having trouble configuring the recorder to capture and export video cropped to a square aspect ratio. Without expertise in AVFoundation I am having a hard time understanding whether this is currently possible to do. Is this currently a supported feature for iOS?

I can see that Issue #1 relates to this question but it was closed 7 months ago and the codebase has changed since that resolution. Specifically, it seems that the functionality associated with useInputFormatTypeAsOutputType has been rewritten.

I have tried to configure the recorder using the following methods without success:

• camera.videoEncoder.outputVideoSize
• camera.sessionPreset
• [camera setActiveFormatThatSupportsFrameRate:width:andHeight:error:]

Any information on this matter would be greatly appreciated.

I'm having a similar issue.

However, I'm using a fullscreen camera and have two black overlays on top & bottom for esthetic purposes. And I've been playing around with cropping to a square after the video has been recorded with the offset from top as high as my top overlay.

Specifically, in the showVideo method in SCViewController.m I've been playing around with cropping the videoUrl file with AVAssetWriter similar to this: http://stackoverflow.com/questions/17882871/how-to-crop-video-into-square-ios-with-avassetwriter

But to no avail. I'd appreciate any direction on this / advice on a more elegant solution.

Hey I just fixed that, sorry about that. You can now set the outputVideoSize to the value you want, it will crop the video automatically if the aspect ratio is different than the input aspect ratio from your camera. Though there is still no way of choosing where it should crop, it will be centered automatically.

Could you guys confirm that it works so I can close this issue? Thanks a lot!

I'd be happy to, but I'm not seeing any new commits at this point. Can you double check that they were pushed?

[rFlex]

Crap. There you go.

@rFlex thanks!
@sethroot mind sharing the code of the method you end up using?

[sethroot]

@rFlex thank you! this is working as intended now.

@dandoen i just copy and pasted code from SCViewController in the iOS example project and specified the CGSize for camera.videoEncoder.outputVideoSize. one thing i can suggest is that you probably don't need to use black overlays if you simply set your camera.previewView to a UIView with square dimensions.

This appears to affect the outputVideo size as stated. How would you
record in square format? Like vine.

You just have to set an outputVideoSize that has the same width and height
(640x640 for instance). Nothing else should be needed.

@rFlex do you know where I'd look if I wanted to try cropping the video from the top instead of the center?
