我想知道openlaszlo 4.9中getMCRef()。attachAudio()的等价物。之前我使用此方法将音频输入到视图以根据音频替换。但在最近的版本中,我尝试将它附加到精灵,但它不起作用。 有什么想法吗?

此代码段应该可以帮到您,它将向您展示如何在OpenLaszlo 4.9.0中从OpenLaszlo SWF8,SWF9和SWF10运行时访问Flash麦克风和Camera对象:

<class name="mediamanager">

  <when property="$as3"><!-- SWF9, SWF10 -->

    <passthrough>
      import flash.media.*;
    </passthrough>

    <!---
    Gets a reference to the camera.

    @returns object: reference to the camera object.
    -->
    <method name="getMicrophone">
      return flash.media.Microphone.getMicrophone();
    </method>

    <method name="getNumMics">
      return flash.media.Microphone.names.length;
    </method>   

    <method name="getMicNames">
      return flash.media.Microphone.names;
    </method>           

  </when>

  <when property="$as2"><!-- SWF8 -->

    <!---
    Gets a reference to the camera.

    @returns object: reference to the camera object.
    -->
    <method name="getMicrophone">
      return Microphone.get();
    </method>

   <method name="getNumMics">
     return Microphone.names.length;
   </method>        

   <method name="getMicNames">
      return Microphone.names;
   </method>        

</when>

&lt; when property =“$ as3”&gt;&lt;! - SWF9,SWF10 - &gt;

<passthrough>
  import flash.media.*;
</passthrough>

<!---
Gets a reference to the camera.

@returns object: reference to the camera object.
-->
<method name="getCamera">
  return flash.media.Camera.getCamera();
</method>

<method name="getNumCams">
  return flash.media.Camera.names.length;
</method>   

<method name="getCamNames">
  return flash.media.Camera.names;
</method>       

&LT; /时&GT;

&lt; when property =“$ as2”&gt;

 <!---
 Gets a reference to the camera.

 @returns object: reference to the camera object.
 -->
<method name="getCamera">
  return Camera.get();
</method>

<method name="getNumCams">
  return Camera.names.length;
</method>

<method name="getCamNames">
  return Camera.names;
</method>

&LT; /时&GT;

有关其属性和方法的完整详细信息,请参阅Flash麦克风和相机对象的Flash文档。此外,这不是在OpenLaszlo中访问麦克风和相机的官方方式,但我使用它们是因为并非所有属性都可以从OpenLaszlo相机和mic API获得,如果您想使用官方API,请参阅官方类文档, :
