    <p>I want to play *.spx files which encoded by <a href="http://www.speex.org" rel="nofollow">Speex</a> on the Web.<br> But I have no knowledge of Flash/Flex or any Flash Audio codec. After Google search for a whole day, I got some solutions, that is:</p> <ol> <li><p>Do something wrapping Speex files with a FLV container because that the Speex is only playable as the audio codec in a FLV container.<br> Now I can play a SPX-Audio-Only FLV file in Flex, I use <code>netStream.play("audio-only-speex.flv")</code>, But I donot know how to wrap a Spx file with FLV container using ActionScript.<br> Any example project?</p></li> <li><p>Decode Spx using AS.<br> I checked out the fllowing pages that they all decoded OGG Vorbis but no Speex :(<br> <a href="http://barelyfocused.net/blog/2008/10/03/flash-vorbis-player" rel="nofollow">http://barelyfocused.net/blog/2008/10/03/flash-vorbis-player</a><br> <a href="http://www.exswap.com/?p=132" rel="nofollow">http://www.exswap.com/?p=132</a><br> <a href="http://mauft.com/2010/11/ogg-vorbis-in-flash" rel="nofollow">http://mauft.com/2010/11/ogg-vorbis-in-flash</a><br> Adobe also provides a AS3 OggVorbis Library which ported by Alchemy:<br> <a href="http://labs.adobe.com/wiki/index.php/Alchemy:Libraries" rel="nofollow">http://labs.adobe.com/wiki/index.php/Alchemy:Libraries</a></p></li> <li><p>FMS: do a server streaming using FMS or Red/Xuggle. I have never heard FMS stuffs before, as well as I'm not sure whether my virtual host can support or not...</p></li> <li><p>Convert every Spx files to MP3.</p></li> </ol> <p>I think the best solution is decoding Spx in AS3, Yes, I'd like to make a Spx Flash Player.</p> <p>So, I downloaded Speex Library from speex.org, installed Adobe Alchemy. After <code>./configure;make</code> the libspeex, build libspeex/speex.c out a <i>libspeex.swc</i> via Alchemy. then, I donot know how to do next. How can I decode the speex audio with AS3?<br> My libspeex.swc: <a href="http://demo.0x123.com/libspeex.swc" rel="nofollow">http://demo.0x123.com/libspeex.swc</a></p> <p><b>In addtion</b>, should I rewrite the libspeex using <a href="http://labs.adobe.com/wiki/index.php/Alchemy%3aDocumentation%3aDeveloping_with_Alchemy%3aC_API" rel="nofollow">Alchemy API</a> before build the libspeex.swc?</p> <p>Although I am not professional in AS, but I have a strong ability to learn. <b>Any advice will be greatly appreciated, Thanks very much.</b></p>

    2. CO@kapep: if you compile against FP 10.x, Alchemy will work in FP 11.x. To quote the [release notes](http://blogs.adobe.com/flashplayer/2011/09/updates-from-the-lab.html): `Existing Alchemy experiments targeting Flash Player 10.x and AIR 2.x are unaffected`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
