如何在videoCompositionWithAsset:applyingCIFiltersWithHandler方法中使用图层指令？

Answer to: How to Use Layer Instructions with videoCompositionWithAsset:applyingCIFiltersWithHandler: #

Based on insights from the engineering team, here's the key information you need to know:

• Core Image filters and layer-instruction-based composition are mutually exclusive when using +[videoCompositionWithAsset:applyingCIFiltersWithHandler:] to initialize an AVMutableVideoComposition. Any layer instructions you add to this composition will not execute—they'll be ignored entirely.
• If you require layer-related functionality in this scenario, you must migrate that layer logic directly into the handler block passed to the method, instead of adding layer instructions to the AVMutableVideoComposition instance itself.
