Video Editing On Android With Media3
summary
Media3’s Transformer module claims to cut editing boilerplate (example: grayscale drops from ~300 to ~30 lines) and already sees broad usage (v1.0.0, ~30% of top‑1000 apps). It supports API 21+ (covers ~99% of devices), is tested on ~170 devices, and performs transmuxing to avoid re‑encode loss or full transcode when needed. Built examples: format conversion, trimming with trim optimization for low latency, image‑to‑video, overlays, custom GL shader effects, MediaPipe/TFLite integration, and two‑sequence compositions (video + background audio).
