How to view the filter graph used by Windows Media Player

Question

i have a video that i cannot render in Graph Edit:

GSpot cannot render:

and AVISynth's DirectShowSource cannot open:

And yet Windows Media Player (12) can play it fine.

How can i figure out the filters that Windows Media Player is using, when DirectShow itself cannot render the file?

---

i tried running GraphEdit as an adminstrator and connecting to a remote graph, but Windows Media Player does not register its graph in the running objects table:

Answer 1

Based on the tag, I assume that this is a .mp4 video file?

Instead of DirectShow, WMP 12 can use the newer Media Foundation framework for rendering files. This is the case for MPEG-4 files.

For the Media Foundation equivalent of GraphEdit, see this question.
