VideoCore is a project inteded to be an audio and video manipulation and streaming graph. It currently works with iOS and periodic (live) sources. It is a work in progress and will eventually expand to other platforms such as OS X and Android. Contributors welcome!
Create a Podfile
with the contents
platform :ios, '6.0'
pod 'VideoCore', '~> 0.2.0'
Next, run pod install
and open the xcworkspace
file that is created.
The SampleBroadcaster project in the sample folder uses CocoaPods to bring in VideoCore as a dependency:
cd sample/SampleBroadcaster
pod install
open SampleBroadcaster.xcworkspace
... or you can build from the command-line:
xcodebuild -workspace SampleBroadcaster.xcworkspace -scheme SampleBroadcaster build

VideoCore's architecture is inspired by Microsoft Media Foundation (except with saner naming). Samples start at the source, are passed through a series of transforms, and end up at the output.
e.g. Source (Camera) -> Transform (Composite) -> Transform (H.264 Encode) -> Transform (RTMP Packetize) -> Output (RTMP)
