PersistentStreamPlayer

Handles the playing of an audio file while streaming, and saves the data to a local URL as soon as the stream completes.

Installation

Add this to your Podfile

pod 'PersistentStreamPlayer'

Usage

PersistentStreamPlayer *remoteAudioPlayer = [[PersistentStreamPlayer alloc] initWithRemoteURL:myHTTPURL
                                                                                     localURL:myFileURL];
remoteAudioPlayer.delegate = self;
[remoteAudioPlayer play];

Features

streaming of audio file, starting playback as soon as first data is available
also saves streamed data to a file URL as soon as the buffer completes
simple play, pause and destroy methods (destroy clears all memory resources)
ability to seamlessly loop the audio file. call player.looping = YES
exposes timeBuffered, helpful for displaying buffer progress bars in the UI
handles re-starting the audio file after the buffer stream stalls (e.g. slow network)
does not keep audio file data in memory, so that it supports large files that don't fit in RAM

The PersistentStreamPlayerDelegate protocol has some helpful event indicators, all optional:

/* called when the data is saved to localURL */
- (void)persistentStreamPlayerDidPersistAsset:(PersistentStreamPlayer *)player;

/* called when the audio file completed */
- (void)persistentStreamPlayerDidFinishPlaying:(PersistentStreamPlayer *)player;

/* called when the play head reaches the buffer head */
- (void)persistentStreamPlayerStreamingDidStall:(PersistentStreamPlayer *)player;

/* called as soon as the asset loads with a duration, helpful for showing a duration clock */
- (void)persistentStreamPlayerDidLoadAsset:(PersistentStreamPlayer *)player;

/* on failure to load asset */
- (void)persistentStreamPlayerDidFailToLoadAsset:(PersistentStreamPlayer *)player;
