Recording Speex audio & Sorenson Spark "type 0" video

[David Nault]

Hi,

I'd like to use the OpenLaszlo to record Speex audio and Sorenson  
Spark "type 0" video (the defaults are Nellymoser Asao and "type 1",  
respectively). I tried poking around in extensions/av/microphone.lzx,  
but the object returned by Microphone.get() doesn't seem to have a  
"codec" property. Can someone kind media expert give me a push in the  
right direction?

Thanks,
David

Wikipedia sez:
Because of some bugs in Flash Player, the first recommended version for
Speex support is 10.0.22.87 and later.

See the docs here:
http://help.adobe.com/en_US/AS3LCR/Flash_10.0/flash/media/Microphone.html
and
http://help.adobe.com/en_US/AS3LCR/Flash_10.0/flash/media/SoundCodec.html

Your best bet would be overriding the _makeDevice() method of
av/microphone.lzx, e.g.:

<microphone>
   <method name="_makeDevice"><![CDATA[
     var dev = super._makeDevice();
     // dev is the microphone
     dev.codec = 'Speex';
   ]]>
   </method>
</microphone>

Even better, enhance the class with a codec attribute, so _makeDevice()
does this automatically - then contribute it back to the platform!
Please file an improvement request if you're not up to doing that.

Let me know how it goes!

Thanks Max. Do you need to do anything special to get the Flash 10  
version of the Microphone class? Right now I'm using lzc (pagan-
deities) with "-runtime=swf8" and the object returned by "_makeDevice"  
doesn't seem to have a "codec" property. Debug.write("codec:",  
dev.codec) prints "codec: undefined" and assigning the value "Speex"  
doesn't have the desired effect). Flash player 10,0,32,18.

Yes, you'll have to compile with -runtime=swf10!
