Question 1

How does Cabbage compare to using AVFoundation directly for video editing?

Accepted Answer

Cabbage abstracts AVFoundation's low-level APIs into a Timeline-based model, making it easier to implement composition features like transitions and custom filters, but it adds an abstraction layer that might be overkill for simple playback tasks.

Question 2

Can I add custom video filters with Cabbage in Swift?

Accepted Answer

Yes, by implementing the VideoConfigurationProtocol and adding it to TrackItem.configuration.videoConfiguration.configurations, as shown in the advance usage section for custom image filters like KeyframeVideoConfiguration.

Question 3

Is Cabbage good for real-time video processing apps?

Accepted Answer

No, Cabbage is designed for video composition and editing, not real-time streaming; it relies on AVFoundation which can introduce latency, so it's better suited for post-processing or export scenarios.

Question 4

Does Cabbage support GIF resources natively?

Accepted Answer

Not out of the box, but it allows creating custom resource subclasses, so you can implement a GIFResource by extending the Resource class, as mentioned in the extensible resource types.

Question 5

What iOS versions does Cabbage work with?

Accepted Answer

Cabbage requires iOS 9.0 or later and is built with Swift 4.x, so ensure your project meets these requirements for compatibility, as stated in the README.

Question 6

How do I export a video using Cabbage framework?

Accepted Answer

Use CompositionGenerator to build an AVAssetExportSession from the Timeline, set the render size, and configure export settings, as demonstrated in the basic usage example with preset names like AVAssetExportPresetMediumQuality.
