Specific Delegate Methods

[jrmsklar]

Added specific delegate methods so that the user of PBJVision can respond to specific changes to the camera. Prior to this change, the user would have needed to implement visionModeWillChange: or visionModeDidChange:, and respond to changes to multiple different camera settings within that one method, such as:

• Changing the camera device (front/back)
• Changing the camera mode (photo/video)
• Changing the output format (preset/square/widescreen)

I've added numerous new delegate methods:

- (void)visionCameraDeviceWillChange:(PBJVision*)vision;
- (void)visionCameraDeviceDidChange:(PBJVision*)vision;

- (void)visionCameraModeWillChange:(PBJVision*)vision;
- (void)visionCameraModeDidChange:(PBJVision*)vision;

- (void)visionOutputFormatWillChange:(PBJVision*)vision;
- (void)visionOutputFormatDidChange:(PBJVision*)vision;

so that the user of this class can respond to each individual action.

Thanks for merging @piemonte! Would you mind updating Cocoapods with this new addition?

[piemonte]

Yeah, not a problem.

Hello guys,

I was trying to play with the widescreen setting. If I wanted to change the size of the output video to a smaller width and height, I have been able to do it. However, the captured video is cropped in the output video. Is there a specific method I need to implement or make a change in a specifc file to ensure that the video capture size matches the final output video render size?

Thanks for your help.

So the question really is how to change the screen size and the square preview that we see when recording the video?
