Windows meadia player and ActiveMovie Window David 6/15/2007 4:42:02 PM Hello all, I have a wmv file which has two video streams. When I play the file using Windows Media Player a second window, “ActiveMovie Window,” is created to show one of the video streams. Is it possible to control this window using WMP sdk. I am guessing the only way to control the window is by using WMP’s graph to gain access to IVideoWindow to set the size and location of the window. Is this possible or, does anyone know of another way to do this using WMP? I have a simi-working DShow application that will play both streams allowing me to have control of both windows. My manager wants the wmv file to play using WMP, and wants me to control the 2nd window. What I would like to do is have WMP and the ActiveMovie Window both be displayed on a C++ dialog. My hope is that I can get some good information from this message board that will help me find out whether this can be accomplished using WMP. -- Best Regards "Failure is the opportunity to begin again more intelligently" – Henry Ford

WMP relies on the filter graph manager and the FGM only knows how to manage the first video renderer, hence the only way to manage more than one renderer is by skipping both WMP and the FGM, which means a custom application that renders the file or one that embeds WMP hacking its way to WMP's internal graph. In any case, WMP itself will not support 2 video streams the way you want it to. You could also write a custom trans-in-place filter that accepts RGB or YUV video and only accepts to be connected to the VMR7 or VMR9: this filter can have multiple inputs and outputs connected to the VMR and can configure the VMR to display the streams side by side by setting the target rectangles in the media type. However it will not be easy to make it work in WMP and it may not work at all with WMV files. -- // Alessandro Angeli // MVP :: DirectShow / MediaFoundation // mvpnews at riseoftheants dot com // http://www.riseoftheants.com/mmx/faq.htm
