Actually, I thought about that but found that the VideoDisplay didn't have that as a method so I found an example that used:
import mx.core.mx_internal; In the program I wrote... pubVideo.mx_internal::videoPlayer.clear(); pubVideo.attachCamera(cam); But that didn't have any effect on the VideoDisplay display. Don't know if I did that right but nothing yelled at me. ;-) sr --- In [email protected], Simon Bailey <[EMAIL PROTECTED]> wrote: > > At a very quick glance, have you tried: > > videoObj.clear(); > > before assigning and attaching you NetStream to the video Object? > > Cheers, > > Simon > > newtriks.com > > On 2 Sep 2008, at 21:43, stephendricketts wrote: > > I have a FB3 application that streams live video to a number of users > and periodically needs to change whose sending video.
