I know about the AVVideoCompositionCoreAnimationTool method to use Core animations and I made it work using AVMutableComposition, but I'm looking for a way to do the same animations through AVAssetWriter. Basically I want to create CAAnimation(s) and use the AVAssetWriter's buffer timestamp as the animation timing method. Then pull the animated properties for each frame.
Is this possible at all? Any guide to the proper direction will be appreciated.
Edit: If you're wondering why not just use AVAssetExportSession instead, it's because my requirements prevent me from using the compression presets, plus I need to use CIFilters which cannot be used currently with CALayers on iOS.
