利用 AVFoundation 和 Core Image 实现视频合成

百姓网在半年前启动了自己的短视频业务。经过多个版本的迭代,我们的移动端应用不光具备了短视频业务的基本能力, 还集成了一项杀手级功能——“魔力拍”。这项功能用起来大概是这样的:

魔力拍演示视频

“魔力拍”所做的事情简单来说就是视频合成。用户输入图片或文字,程序拿着用户的输入和原始视频模板经过一系列处理,最终生成目标视频。 业务流程看着非常简单:

Pegasus:基于 React Native 的 App 动态化方案(下)

上期,我们介绍了 RN 中 JS 和 native 的通信方案,并以 native library 形式在我们的 app 内顺利集成了 RN 模块。今天我们继续讨论:

  1. RN 模块对外依赖的解决方案;
  2. RN 模块的开发和调试问题;
  3. RN 模块代码的动态部署问题。

对外依赖

Pegasus:基于 React Native 的 App 动态化方案(中)

我们以 UIViewController 和 Activity 包裹 Component 的方式,迈出了百姓网主 app 接入 RN 的第一步。本期,我们将更具体地介绍 Pegasus 的设计和实现。着重回答以下问题:

  1. 怎么把 Pegasus 集成到已有的 native 项目?
  2. 怎么处理 RN 和 native 的互相通信?

集成

Pegasus:基于 React Native 的 App 动态化方案(上)

React Native 和 app 动态化一直以来都是业内的热门话题。百姓网移动技术团队在过去一段时间就这两个话题展开了积极探索,并积累一点宝贵的人生经验。虽然作为分享者,我希望一下子把事情全讲清楚,但是限于移动端阅读体验,此次我们还是会分上、中、下三篇文章陆续发布。

在系列文章里,我们将注重讨论以下几个话题:

  1. 百姓网的 React Native 之路;
  2. RN 模块集成到已有 native 项目的方案;
  3. RN 模块中 JavaScript 和 native 代码通信问题;
  4. RN 模块对外依赖的解决方案;
