ios - iOS AVAsset integrating with C++ code

Question

Use-case

1. Existing C++ code working with stdio files ( FILE* )
2. To be integrated into an iPhone Objective-C app
3. Should be used to read media files from the Asset Library

Is it possible to get the NSFileHandle/Descriptor for an AVAsset object such that it'll be readable using stdio 'fread'/'read' ?

Any help will be appreciated.

Answer 1

简单，而不是使用assetWithURL 创建一个AVAsset，使用[NSFileHandle fileHandleForReadingFromURL]。
