<li>
<p>
Adobe FMS (RTMP Server) fix: Invoke server-side <code>getStreamLength()</code> call to determine duration. (Red5 and other free RTMP servers use NetStream <code>onMetaData()</code> to pass duration.)
</p>
</li>
<li>
<p>
Fix <code>html5Unload()</code> by loading a tiny base64-encoded data: URI WAVe file where supported. Elsewhere, use <code>about:blank</code>. This fixes errors in Chrome where the browser attempts to load the url "null" (a string.)
</p>
</li>
<li>
<p>
D'oh! Fix HTML5 sprite regression where <code>_oncanplay()</code> was not being picked up &amp; fired, sound would not play on first click.
</p>
</li>
<li>
<p>
HTML5: Fix double-play bug with <code>autoPlay: true</code>. Correct edge case where <code>onposition()</code> items would sometimes be cleared if called/assigned before <code>play()</code>.
</p>
</li>
<li>
<p>
<code>ontimeout: function(status) {}</code> callback parameter corrections. Fix missing error { <code>type: 'INIT_TIMEOUT'</code> } for missing/404 SWF case, and <code>INIT_FLASHBLOCK</code> for flashblock-specific case.
</p>
</li>
<li>
<p>
HTML5: Apply volume to cloned sounds in HTML5 <code>multiShot</code> case.
</p>
</li>
<li>
<p>
Fixed issue in <code>_processOnPosition</code> where the item in <code>onPositionItems[i]</code> can be undefined mid-loop if the callback that is triggered changes the length of the <code>onPositionItems</code> array, where <code>onPositionItems.length</code> becomes zero and there's an uncaught <code>TypeError</code> when trying to access <code>item.fired</code> the next time around.
</p>
</li>
<li>
<p>
Fixed mute in HTML5.
</p>
</li>
<li>
<p>
Fix <code>onload</code> in Firefox 3.6 with no flash (and yes, Firefox 25 is the current release. :D)
</p>
</li>
<li>
<p>
Correct event removal (cloned HTML5 nodes) - <code>onended</code> &rarr; <code>ended</code>

Use 100% HTML5 mode by default, where available. <code>preferFlash: false</code> is now the default setting. Firefox does MP3 on Vista (and newer) via HTML5, and recently (via Firefox Aurora builds) on OS X - the last major hold-out. The vast majority of browsers now support MP3 via HTML5, thus reducing the reliance on Flash.

Reboot into 100% HTML5 mode where supported if flash fails after loading, i.e., local/offline/file:// or other edge case.

Init enhancement: If <code>preferFlash: true</code> but <code>useFlashBlock: false</code> (the default SM2 config) and flash timeout / blocked case occurs, SM2 will reboot reboot into 100% HTML5 mode if available so init can succeed. If flash block handling is enabled, user interaction will be required to whitelist the flash movie and init will be delayed until the SWF loads.
</p>
</li>
<li>
<p>
Correct <code>reboot()</code> to allow 100% HTML5 mode when Flash was previously required due to <code>preferFlash: true</code>. Previously, <code>soundManager.audioFormats.mp3.required = false; soundManager.reboot()</code> did not result in 100% HTML5 mode under Firefox. Now works as expected.
</p>
</li>
<li>
<p>
HTML5 unloading: Firefox was supposed to like assigning <code>''</code> to <code>Audio().url</code> for canceling requests, unloading and destroying the decoder (perhaps only on <code>&lt;audio&gt;</code>, in retrospect?) - similarly, <code>.src = null</code> did not seem to work, possible request to <code>./</code> - undesirable.
</p>
<p>
Now using more-conservative <code>null</code> URL for unload / destruct on webkit, iOS and others, and <code>emptyURL</code> for Firefox (user-customizable, <code>'about:blank'</code> by default.)

More HTML5 safety checks so that <code>buffered</code> can't go beyond 100%.

Improve Flash 9 <code>load()</code> -&gt; <code>onload()</code> failure case, when loading a non-404 (eg., HTTP 301 -&gt; 200) with non-audio content. Improved messaging for Flash 8, Flash 9 + HTML5 with zero-duration (invalid / unsupported sound) case.

Fix flash-only (no HTML5 / <code>useHTML5Audio: false</code>) init case, e.g., running under IE 8.

HTML5: Fix legacy "overloaded" case when <code>soundManager.play('someID', 'some.mp3');</code> is called twice, second call would fail. This shortcut method is deprecated, and not recommended for use other than a conveience when in development / testing.

<code>createSound()</code> no longer requires an <code>id</code> property. If omitted, a unique <code>id</code> will automatically be generated for the new sound object with a prefix based on the SM2 setup option <code>idPrefix</code>.
</p>
<p>
Specifying an <code>id</code> is useful if you want to look up the sound via <code>getSoundById()</code> - otherwise, you can simply use the object returned by the <code>createSound()</code> call.

<p>
<code>multiShot</code> + <code>multiShotEvents</code> for HTML5 <code>Audio()</code>-based sounds, allowing layered / "chorused" playback if <code>play()</code> is called and <code>multiShot: true</code> has been specified to either <code>createSound()</code> or <code>play()</code>. Behaviour should mimic that of Flash 9. If <code>multiShotEvents: true</code> is specified, <code>onfinish()</code> will fire for each instance. Does not apply to mobile clients (e.g., iOS and Android) which only allow one sound to be played at a time.
</p>
<p>
Implementation summary: A <code>new Audio(src)</code> instance is created with an <code>onfinish</code> listener, and played immediately. It is unloaded and destroyed when playback finishes.
</p>
<p>
Caveat #1: If a position argument is provided eg., <code>play({ position: 1000 })</code>, the cloned <code>Audio()</code> instance must wait for a HTML5 <code>canplay</code> event before a seek and playback can begin. This may mean playback *could* have a slight delay vs. playing without the position offset.
</p>
<p>
Caveat #2: The from/to parameters used for "sound sprites", e.g., <code>{ from: 500, to: 1500 }</code>, are not presently supported under multiShot.
</p>
<p>
Caveat #3: multiShot is not supported where only a single audio instance can be playing at once, e.g., iOS (iPhone/iPad) and some Android devices.
</p>
<p>
Secondary instances are "fire-and-forget", similar to the Flash 9 implementation, and fire no events other than <code>onfinish()</code>. They do not respond to position, volume etc. after playback has begun.
</p>

<!-- not quite stable/finished yet. -->

<p>
<b>Experimental</b>: <code>createSound()</code> can be called without a <code>url</code> property, and will work in most cases (excluding old Flash 8-based edge cases of <code>.load({url:...}).play()</code> or <code>.play({url:...})</code>, which didn't work previously anyways.)
</p>
<p>
Currently, sounds determine their HTML5/Flash requirements at <code>createSound</code> time based on <code>url</code> or <code>type</code>. Some refactoring needs to be done to allow sound objects to dynamically switch between HTML5 + Flash, so omit <code>url</code> with caution. If you intend to play only a particular MIME type and the <code>url</code> is not known in advance, you can specify <code>type</code> to <code>createSound()</code> in the event mixed-mode HTML5/flash switching problems are encountered.

<h3><b>V2.97a.20130324</b> - Fix for playlist/event chaining when using <code>flashVersion = 8</code> with Flash Player 11.6.602.171. HTML5 iOS <code>load()</code> fix. Added Opus to audio formats. (<a href="../../download/soundmanagerv297a-20130324.zip" class="norewrite">Download archived version</a>)</h3>
<ul>
<li class="in">
<p class="compact">Bug fixes</p>
<ul class="nested compact flat">
<li>
<p>
Flash Player 11.6.602.171, released by Adobe on 02/26/2013, introduced an issue with SM2's default Flash 8 (<code>flashVersion: 8</code>) API-based JS/Flash interaction, where SM2 methods called from callbacks such as <code>onfinish()</code> would not work. This primarily broke methods used for playing sounds in sequence, serially loading a series of sounds and so on. (See <a href="https://getsatisfaction.com/schillmania/topics/recent_chrome_update_seems_to_have_broken_my_sm2_audio_player">discussion</a> for more.)
</p>
<p>
Note that this does not affect cases where <code>soundManager.setup({ flashVersion: 9})</code> is being used; however, SM2 does use <code>flashVersion: 8</code> by default.
</p>
<p>
Specifically, Flash-initiated events (such as a sound finishing) make Flash -&gt; JS calls to the SM2 API, which subsequently call user-specified event handlers. If the user-specified SM2 <code>onfinish()</code> handler immediately calls a SM2 method like <code>play()</code> that makes a JS -&gt; Flash call, this call either silently fails or is blocked. Other JS + Flash libraries that use similar callback patterns may also be affected, if their SWF is built targeting the Flash 8 API.
</p>
<p>
Suspecting a timing or recursion/stack issue, it was found that introducing a <code>setTimeout(callback, 0)</code> to user-specified SM2 callbacks like <code>onfinish()</code> restored sequential/playlist functionality.
</p>
<p>
Flash Player 11.6.602.180, relased by Adobe on 3/12/2013, exhibits the same behaviour. To avoid additional hacks, SM2 applies this to all Flash 8-based API callbacks regardless of what version of Flash Player is installed. No regressions are anticipated as a result of this change.
</p>
<p>
Alternately, this issue can be avoided by using <code>soundManager.setup({ flashVersion: 9 })</code> as the Flash 9-based API does not appear to have this problem.
</p>
</li>
<li>
<p>
HTML5: Fix for iOS <code>load()</code> case when using an auto-load and looping pattern (related <a href="https://getsatisfaction.com/schillmania/topics/autoload_on_ipad_loop_error">discussion</a>).

New <code>soundManager.reset()</code> method. Similar to <code>reboot()</code>, but also nukes any registered <code>onready()</code> and related callbacks.

Prerelease Firefox builds can play MP3 audio via HTML5 in some cases, as part of a move to support H.264 video (see <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=799318">Bugzilla #799318</a> for details). Firefox 20 (nightlies, and Aurora channel builds in January 2013) can get native MP3 support via Windows Media Foundation (OS-level codec support) components on Windows 8, Windows 7, and <a href="http://news.ycombinator.com/item?id=4944080">soon</a>, Windows Vista. As of 12/2012, OS X support <a href="http://news.ycombinator.com/item?id=4945149">is planned</a>, and Windows XP support <a href="http://news.ycombinator.com/item?id=4944080">is not</a>. <span class="sidenote">(Disclaimer: Vista, OS X and XP notes sourced from comments on Hacker News; see links).</span>
</p>
<p>
When enabled with <code>media.windows-media-foundation.enabled = true</code> under <code>about:config</code>, Firefox may be able to play MP3s via HTML5 and thus get "100% HTML5 mode" when <code>soundManager.setup({preferFlash: false})</code> is used.

At time of writing (12/30/2012), Firefox 20 (nightly) returns <code>""</code> for <code>canPlayType('audio/mpeg; codecs="mp3"')</code>, a test commonly used to query for MP3 support under HTML5 and one which works in other modern browsers. Firefox's behaviour differs because it is trying to follow the MPEG spec, which does not include an explicit MP3 MIME type. Instead, <code>canPlayType('audio/mpeg')</code>, which is in-spec, presently returns a "maybe" when MP3 is supported under Firefox.

Windows 8 Store Apps (IE 10/"MSAppHost" in UA) don't support Flash or ActiveX, except for (at time of writing), three special ActiveX controls.

Improve HTML5 audio load/playback reliability + stability on iOS, and for object reuse cases (<code>play()</code> -&gt; <code>load({url: ...})</code>. Prior behaviour was making initial HTTP request when object was created (meta/preload, not necessarily loading entire file.) Request now only happens with preload/load/play-related calls.
</p>
</li>
<li>
<p>
HTML5: Firefox seems to have changed when unloading HTML5 audio, <code>url = ''</code> now loads hosting page HTML (boo) instead of <code>null</code> / no request. Changed to <code>about:blank</code> like everyone else. Also fixed boolean logic on <code>isMovieStar</code> assignment.
</p>
</li>
<li>
<p>
Add <code>audio/mp3</code> and related MIME checks for flash, correct edge case where <code>play({type:'audio/mp3'})</code> would use HTML5 when <code>preferFlash = true</code>, due to seeming lack of Flash support for the MIME type.
</p>
</li>
<li>
<p>
Fixed old Flash 8 <code>onload()</code> edge case where loading from cache might return incorrect <code>didLoad: false</code> result - corrected by checking for a non-zero sound duration.
</p>
</li>
<li>
<p>
Properly reset <code>SMSound.id3 = {}</code> with internal resetProperty and public methods like <code>load()</code>.
</p>
</li>
<li>
<p>
Edge case fix: Don't attempt to remove flash unless reference exists (prevent false warning when <code>reboot()</code> called in 100% HTML5 mode.)
</p>
</li>
<li>
<p>
Correct empty options JS error on internal <code>_setup_html5()</code> when reusing HTML5 audio object per <a href="https://getsatisfaction.com/schillmania/topics/possible_bug_when_html5_audio_tag_is_reused_20120527_release">V2.97a.20120527 bug report</a>
</p>
</li>
<li>
<p>
Fix minor false positive (undocumented error handler case) with HTML5 <code>play()</code> falsely reporting 32-sound ceiling edge case and calling <code>SMSound.onplayerror()</code> (if assigned) when using flashVersion = 9. Should only apply when flash 9 is being used for playback, and ceiling hit.

Finally assign + use <code>SMSound.id</code> (instead of sID), matching <code>createSound({id: 'foo'})</code> pattern; maintain legacy sID property (ancient behaviour, originally intended to avoid potential namespace conflicts many years ago - now silly and not a concern.)
</p>
</li>
<li>
<p>
Improved handling of <code>whileloading()</code> vs. HTML5 <code>onload</code> (when using HTTP range/partial requests).
</p>
<p>
HTML5 <code>onload()</code> (now triggered via native <code>canplaythrough</code> event) may fire early, followed by numerous HTML5 <code>progress</code> requests during playback as the audio object requests and buffers more audio ranges (eg., 0-10 seconds), eventually matching the total sound duration.
</p>
<p>
Bytes loaded / total are not available, so bytesLoaded instead reflects a fraction of "duration loaded", between 0 and 1 as data is buffered in. Previously, <code>whileloading</code> events would not fire once <code>onload</code> had fired under HTML5.
</p>
</li>
<li>
<p>
New (undocumented, for now) <code>buffered</code> array on SMSound objects; list of objects following the pattern <code>SMSound.buffered = [{ start: 0, end: 706 }]</code> representing loaded time ranges (somewhat similar to HTML5 TimeRanges spec, but using static properties instead of method calls with an index parameter.) Array will initially be empty, zero-length. This can be looped through to show overlays of "loaded" time fragments on progress bars, for example.</p>
<p>SMSound <code>buffered</code> is updated during <code>whileloading()</code> calls, where values are provided by the browser. For flash, will always be one item with <code>{ start: 0, end: SMSound.duration }</code> assigned. Also stopped sending 1/1 values to <code>whileplaying()</code> at <code>onload()</code>, since HTML5 can fire <code>onload()</code> (via <code>canplaythrough</code>) very early followed by many progress (<code>whileloading()</code>) events.
</p>
<p>
<b>Support note:</b> Not all browsers (eg., Safari 5.1.7) appear to provide buffer / TimeRanges data for HTML5 audio objects. At time of writing (06/2012), Firefox, Chrome Canary, IE 9 and Opera provide TimeRanges alongside progress events.
</p>
</li>
<li>
<p>
Upgraded demos to use to <code>soundManager.setup({...})</code> for most configuration cases (vs. setting <code>soundManager.url</code>, <code>soundManager.defaultOptions.autoLoad</code> directly etc.)
</p>
</li>
<li>
<p>
Warn if <code>soundManager.setup()</code> called with <code>url</code> or <code>flashVersion</code>, and init has already fired (ie., flash options already set + movie already loaded) where changes will not take effect until <code>soundManager.reboot()</code>.
</p>
</li>
<li>
<p>
Assign top-level soundManager properties (eg. <code>soundManager.url</code>) from <code>soundManager.setupOptions</code> at <code>DOMReady</code> time; this allows legacy <code>soundManager.url = ...</code> assignment to work, and helps to ensure legacy-style, directly-assigned top-level property values get written back to <code>soundManager.setupOptions</code>.

Fix for <code>ontimeout()</code> regression seen when using lazy-loading / SM2_DEFER introduced with V2.97a.20120513; bug introduced when making edits to pass newer jslint rules regarding <code>return</code> within <code>if...else</code> blocks.
</p>
</li>
<li>
<p>
Replaced <code>instanceof Function</code> with "safer" <code>typeof x === 'function'</code> for <code>onready()</code>, <code>ontimeout()</code> and related callback argument checks as GWT + JSNI was passing arguments that failed the <code>instanceof</code> check.

</p>

Improved handling for special Safari page load case: When a new tab is opened that does not have focus, the Flash SWF does not load/init until the tab is brought to the foreground. SM2 now recognizes this special case and waits until <code>window.onfocus()</code> before attempting to do the JS/Flash part of init. Previously, it would fail with a timeout.
</p>
<p>
Code written to originally handle Safari 3.1, which did not support <code>document.hasFocus()</code>, was modified and updated for this purpose. The Safari 3.1 logic previously deferred SM2's start-up in a similar fashion. (The old Safari 3.1 <code>mousemove()</code> focus-detection hack has been removed as Safari 4 has been out since mid-2009, and Safari 5 since mid-2010.)
</p>
</li>
<li>
<p>
SM2 init process will now delay and retry if no Flash response, and SWF has loaded &gt; 0 and &lt; 100%. Timeout will now happen only after delay and when SWF has loaded 100%. Should help prevent first-visit (non-cached) failure on very slow or laggy connections.
</p>
</li>
<li>
<p>
Added note about potential Firefox regression: Offline JS/Flash start-up (viewing HTML pages via <code>file://</code> and/or <code>c:/</code> and so forth), possibly not working as of Firefox 9 and newer (at time of writing, also up to and including Firefox 12), even despite special security whitelisting under Flash Player "trusted locations" preferences / control panel.
</p>
<p>
After successful Flash -&gt; JS call, SM2's "return" JS -&gt; Flash call fails with unusual JS/Flash exception, "Error in ActionScript" error with no further detail. Offline viewing still works in other browsers.
