Is it possible to replace WMP EVR presenter with a custom one? RRS feed

  • Question

  • Hi,

    I am looking for a way to get the window size, location and clipping when I play a video on WMP using media foundation.

    I was able to write my own custom MFTransform and get WMP to use it, but I didn't find a way to replace WMP EVR or customize it.

    I tried to get access to the EVR interface from my custom MFT without success.

    any idea of how to approach this issue?

    Cheers

  • WMP does not support a custom presenter or EVR.  You might be able to navigate the window hierarchy (using ::FindWindowEx or similar APIs) but it would not necessarily be easy or performant to navigate the window heirarchy down to the WMP rendering window.
