DirectShowSource with Karaoke-DX?

[mc510]

I'm trying to open a karaoke CDG file with avisynth and am getting "the script's return value was not a video clip." I've got Karaoke-DX installed, which is a DirectShow filter for CDG files, and it is working -- I can view the CDG file properly in Windows Media Player. But not with avisynth?

My script has only this one line:

DirectShowSource("test.cdg")

Thanks for any help!

1) Does your cdg file play in GraphEdit?

2) If so, post a screenshot of its graph.

Yep, graphedit is able to render it. The karaoke-dx settings allow you to choose whether or not to use the Microsoft Video Mixing Renderer 9 ... I don't know that that is, but I tried it both with and without; graphs are attached.

Save a graph with the test.cdg, CDG Parser and CDG2Video Transform filters (delete the Video Renderer and the other redundant stuff). Open the grf in AviSynth:

DirectShowSource("file.grf", audio=false)

Does that work?

[mc510]

Yes it does! Thanks, Wilbert!

I still need to bring in the mp3 audio; can I do that in my avisynth script or do I need to do that at virtualdub?

Okay, I figured that last bit out on my own:

v = DirectShowSource("test.grf", audio=false)
a = DirectShowSource("test.mp3", video=false)
AudioDub(v,a)
