My DirectShow Audio Renderer filter doesnt get called from WMP Sasha Nikolic 11/21/2008 1:24:05 PM Hi, I have implemented one audio source filter and one audio renderer filter. If I connect & play them in GraphEdit all works ok. Now I want to use them both in WMP, the source filter gets called since I registerered extension at: HKEY_CLASSES_ROOT\Media Type\Extensions\.myextension\Source Filter... But my renderer filter is not called from the WMP, instead I am getting the WMP error "cannot play the file" (I have created my own CLSID's for media subtypes). Does anyone have ideas why WMP refuses to talk to my renderer filter? Actually, I am not sure how WMP decides which renderer to use (besides "merit"), does it probes all installed renderers for a given media type? Thanks, Sasha

If you hack WMP to overwrite this choice, you will break it. Which means, you can make WMP use third-party renderers. WMP is not a generic DirectShow frontend, it's a player. -- // Alessandro Angeli // MVP :: DirectShow / MediaFoundation // mvpnews at riseoftheants dot com // http://www.riseoftheants.com/mmx/faq.htm
