Using the event logger with a BC iOS Player
/* Create an event logger for a player. Note how we attach it to the event emitter for a player. You can attach the logger to the catalog's event emitter as well! */
BCEventLogger *playerLogger = [[BCEventLogger alloc]initWithEventEmitter:player.playbackEmitter];
/* If you're in verbose mode, this string will be prepended to all the logging */
[playerLogger setLoggingPrefix:@"Player"];
/* The logger is verbose by default and prints out every event and all the properties of that event. Non-verbose mode just prints out the event name */
playerLogger.verbose = false;
/* We don't recommend leaving this on for "production" code but it can be handy to know what component sent a particular event when debugging. If you add this line, the sender will be printed out as well. */

Results from performance testing methods of converting a UInt8Array into a base64-encoded string in Firefox 28/OS X.

Converting the Uint8Array to a "binary string" with String.fromCharCode and then using btoa:
