AVAudioPlayer Streaming Support
AVAudioPlayer provide support for streaming audio content?
AVAudioPlayer class does not provide support for streaming audio based on HTTP URL's. The URL used with
initWithContentsOfURL: must be a File URL (
file://). That is, a local path.
As mentioned in Core Audio Essentials, the
AVAudioPlayer class is ideal for applications that require a simple Objective-C interface for audio playback, are not concerned about audio positioning or precise synchronization, and are not playing audio from a network stream.
To play streamed audio, connect to a network stream using the
CFNetwork interfaces from Core Foundation, such as those in
CFHTTPMessage. Parse the network packets into audio packets using Audio File Stream Services (
AudioToolbox/AudioFileStream.h) and play the audio packets using Audio Queue Services (
AudioToolbox/AudioQueue.h). You may also use Audio File Stream Services to parse audio packets from an on-disk file.
AVPlayer (available in iOS 4.0 and later) may also be used to stream audio content.
A sample called
AudioFileStreamExample demonstrates the use of Audio File Stream APIs and can be found in the Mac OS X Reference Library.
