6. 重构 MP4Clip.tick 支持获取任意时刻的图像帧、音频 PCM 数据

破坏性更改

1. MP4Clip 构造函数移除 start、end 字段
   • 迁移方法：新支持 deleteRange 方法，用于支持更灵活、性能更好地裁剪片段
2. MP4Clip 构建函数参数 audio 字段默认值变更 false -> true，默认保留 MP4Clip 的音频
   • 迁移方法：搜索 new MP4CLip 关键字，需要移除音频的素材添加参数 { audio: false }
3. 废弃 MP4Previewer；1.0 将删除该该 API

Support for basic clipping functionality

1. Added MP4Clip.deleteRange to remove unwanted segments.
2. Added MP4Clip.thumbnails to return thumbnails of all keyframes.
3. Added asset cloning with IClip.clone.
4. Added MP4Clip.splitTrack to split video tracks into separate assets.
5. Added three new clip demos: thumbnails, preview trimming, and video track splitting.
6. Refactored MP4Clip.tick to support retrieving image frames and audio PCM data at any given moment.

Breaking Changes

1. Removed start and end fields from the MP4Clip constructor.
   • Migration: Use the new deleteRange method for more flexible and better performing clip trimming.
2. Changed default value of audio parameter in MP4Clip constructor from false to true, preserving audio by default.
   • Migration: For assets where audio should be removed, add the parameter { audio: false } when creating a new MP4Clip.
3. Deprecated MP4Previewer; it will be removed in version 1.0.
   • Migration: Replace MP4Previewer.preview with MP4Clip.tick.
