== SoundManager 2: JavaScript Sound for the Web
|
|
|
|
By wrapping and extending HTML5 and Flash Audio APIs, SoundManager 2 brings reliable cross-platform audio to JavaScript.
|
|
|
|
== HTML5 Audio() Support (Beta-ish)
|
|
|
|
* 100% Flash-free MP3 + MP4/AAC where supported, compatible with Apple iPad 3.2, iPhone/iOS 4
|
|
* Fallback to Flash for MP3/MP4 support, as needed
|
|
* SM2 API is unchanged, transparent; HTML5/flash switching handled internally
|
|
* HTML5 API support approximates Flash 8 API features, minus ID3, plus buffering
|
|
* Some other formats (WAV/OGG) supported via HTML5, depending on browser
|
|
* See soundManager.useHTML5Audio for implementation details.
|
|
|
|
== Basic API Features (Flash 8)
|
|
|
|
* Load, stop, play, pause, mute, seek, pan and volume control of sounds from Javascript
|
|
* Events: onload, whileloading, whileplaying, onfinish and more
|
|
* ID3V1 and ID3V2 tag support for MP3s (title, artist, genre etc.)
|
|
|
|
== Shiny Flash 9 Features
|
|
|
|
* RTMP / Flash Media Server streaming support (new, experimental)
|
|
* MPEG-4 (AAC, HE-AAC, H.264) audio support
|
|
* "MultiShot" play (layered/chorusing effects)
|
|
* Waveform/frequency spectrum data
|
|
* Peak (L/R channel volume) data
|
|
* Audio buffering state/event handling
|
|
|
|
== General Tech Stuff
|
|
|
|
* Full API Documentation with examples and notes
|
|
* console.log()-style debug output and troubleshooting tools
|
|
* Community-based discussion/support
|
|
|
|
== As heard on The Internets
|
|
|
|
A few nifty sites that have implemented SM2 for driving audio:
|
|
|
|
* Muxtape
|
|
* SoundCloud / The Cloud Player
|
|
* 8tracks
|
|
* Last.fm
|
|
* Opera (media player component)
|
|
* Discogs
|
|
* Mixcrate

== Merged fork ( kjvarga: http://github.com/kjvarga/SoundManager2/ )
|
|
|
|
This SM2 fork contains the SoundManager2 implementation that is used on http://www.kazaa.com.
|
|
|
|
We added RTMP support to SM2 which is now part of the SM2 (experimental) branch as of V2.96a.20100606.
|
|

|
For more background on the addition of RTMP check out http://getsatisfaction.com/schillmania/topics/soundmanager_doesnt_support_rtmp
|
|
|
|
Our old branch of development has been moved to http://github.com/kjvarga/SoundManager2/tree/pre_merge.

|
== Changes
|
|
|
|
In addition to the documented SM2 options, we have added the following.
|
|
|
|
New options to SM2:
|
|
|
|
* <tt>ondebuglog</tt> callback called with every debugging message. Useful if you need to programatically have access to the debug logs. We use this in our automated reporting of stream failures for QA.
|
|
|
|
New options to createSound:
|
|
|
|
* <tt>bufferTimes</tt> optional array of buffer times for double/multiple-buffering. Just specify an array of incrementing buffer sizes (in seconds) e.g. [0.5, 2, 8] for a half-second, then 2 second, then 8 second buffer. Buffers increment when full and reset to the smallest buffer when empty, or when starting to play an unbuffered portion of the stream.
|
|
* <tt>onstats</tt> callback called with statistics including how long it took to connect to the server, and how long it took to play (useful for QA).
|
|
|
|
Our FMS server has some peculiarities that we have to deal with:
|
|
* bytesLoaded is always 0 for a streaming sound
|
|
* NetStream.Play.Stop is sent when it shouldn't
|
|
* We cannot get the stream length using a typical <tt>getStreamLength</tt> call
|
|
* We cannot get bandwidth information
|
|
|
|
== Debugging
|
|
|
|
1. Set <tt>soundManager.debugFlash = true;</tt>
|
|
2. Use a debug version of the SWF e.g. soundmanager2_flash9_debug.swf
|
|
3. Open the Flash IDE. Open the SM2 source code files. Start a remote debugging session.
|
|
4. Refresh the application in the browser (make sure caching is off).
|
|
5. The SWF should connect to Flash and allow you to step through the source.
|
|
|
|
If it doesn't:
|
|
1. Make sure that the Flash version you have installed supports debugging
|
|
2. Make sure that the Flash debugger application is using the same version of Flash.
