FFmpegWrapper

FFmpegWrapper 是一些 FFmpeg libav 函数的轻量级 Objective-C 包装器。

安装

注意：此项目包含作为子模块的 FFmpeg-iOS，您需要单独构建。

1. 将此作为 git 子模块添加到您的项目中。

   $ git submodule add Submodules/FFmpegWrapper https://github.com/OpenWatch/FFmpegWrapper.git
   

2. 将 FFmpegWrapper.xcodeproj 拖入您的项目文件中。

3. 在构建阶段将 FFmpegWrapper 添加到您的目标的 Target Dependencies。
4. 在构建阶段将 libFFmpegWrapper.a 添加到您的目标的 Link Binary with Libraries。

用法

FFmpegWrapper.h 包含最新的文档，因此建议首先检查那里，因为此文档可能会由于快速开发而过时。

使用在 options 字典中指定的参数将位于 inputPath 的文件转换为位于 outputPath 的新文件。这两个可选回调用于监视排队任务的进度和完成，并且总是在主线程上调用。目前所有对此函数的调用都排队在同步的内部分发队列中。

- (void) convertInputPath:(NSString*)inputPath outputPath:(NSString*)outputPath options:(NSDictionary*)options progressBlock:(FFmpegWrapperProgressBlock)progressBlock completionBlock:(FFmpegWrapperCompletionBlock)completionBlock;
