I am testing the WebCam sample that comes with the SDK.  How do you make the captured  image/video smaller?  I have tried a couple of things but nothing happens.  Is it the resolutionfactor that needs changing?

Here is part of the code:

<rtc:ConnectSessionContainer id="cSession" authenticator="{auth}" width="100%"

height="70%" roomURL="https://collaboration.adobelivecycle.com/genius123/myfirstroom" >

<mx:Panel title="Webcam" width="100%" height="100%"

       paddingTop="10" paddingLeft="10" paddingRight="10" paddingBottom="10" creationComplete="onCreationComplete()">

  <rtc:WebcamPublisher id="webCamPub"  width="10" height="5" resolutionFactor="5" />

<mx:VBox width="100%" height="100%" id="clickedContainer"/>

        <mx:HBox horizontalGap="10" verticalGap="15" paddingLeft="10" paddingTop="10" paddingBottom="10" paddingRight="10" width="100%" height="25%">

            <mx:Repeater id="rp" dataProvider="{cSession.userManager.userCollection}" width="100%" height="100%" >

           <mx:VBox width="100%" height="15%" horizontalAlign="center" horizontalGap="5">

          <rtc:WebcamSubscriber webcamPublisher="{webCamPub}" width="100%" height="100%" publisherIDs="{[(rp.currentItem as UserDescriptor).userID]}" click="onClick(event)" userBooted="onBooted(event)" streamChange="onCameraPause(event)" />

           <mx:Button  label="Start"  click="onBtnClick(event)"  visible="{(rp.currentItem as UserDescriptor).userID==cSession.userManager.myUserID}" />

           </mx:VBox>

            </mx:Repeater> 

        </mx:HBox>

    </mx:Panel>

</rtc:ConnectSessionContainer>

Thanks

Hi ,

Normally, If you want to make the captured image/video bigger, you need to increase the resolutionFactor. The resolutionFactor gets multiplied with the default width and height ( the width and height is dependant on the aspect ratio value , the default is standard i.e. 128 X 128 ). The default value of resolutionFactor is 1. So, the captured image by default is 128 X 128. Now, since resolutionFactor is an integer and its already 1, you won't be able to lower it but you can only increase it.

So, to lower you can link your project to the source provided and change the updateCameraSettings function in WebcamPublisher to set the desired width and height you want. A look at this function will make things more clear too as this function sets the captured width and height values.

Or you can also lower the Standard aspect ratio values in StreamManager( currently it's 128). If you do not want to link project to the source, you would have to subclass WebcamPublisher and override the updateCameraSettings function in it.

We have never faced an use case before whereby user had to lower the captured image even from 128 , so we kept the factor as an int. However, in future, we might think of doing it as number to give users greater flexibility.

And as far as the display on the subscriber side is concerned, you need to change the width/height of WebcamSubscriber or WebCamera component depending on whatever you are using.

Hope this helps
