FFmpegWrapper is a lightweight Objective-C wrapper for some FFmpeg libav functions.

Note: This project includes FFmpeg-iOS as submodule which you will need to build separately.

1. Add this as a git submodule to your project.

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

2. Drag FFmpegWrapper.xcodeproj into your project's files.

3. Add FFmpegWrapper to your target's Target Dependencies in Build Phases.

4. Add libFFmpegWrapper.a to your target's Link Binary with Libraries in Build Phases.

FFmpegWrapper.h contains the latest documentation so it would be advisable to check there first as this document may be out of date due to rapid development.

Converts file at inputPath to a new file at outputPath using the parameters specified in the options dictionary. The two optional callbacks are for monitoring the progress and completion of a queued task and are always called on the main thread. All calls to this function are currently queued in a synchronous internal dispatch queue.

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

Like FFmpeg itself, this library is LGPL 2.1+.
