Win 8 camera metro application fails to record video RRS feed

  • Question

  • The camera metro application in win 8 sometimes, about 20%, fails to record video. In this case I got pop up with the following error: "This file can't be saved. Something went wrong while recording this video".  

    I have another application in which I don't see this error.

    May you please help analyzing this error:

    1. How can I know what causes this error? Is it user or kernel space error?

    2. Which trace/logging tools can I use for analysis? Can windows event viewer give initial indication?

  • I found that windows does not invoke the DispatchState, with KSSTATE_PAUSE, AQUIRE and RUN (of the video pin) of the AVStream driver at all.

    Although it does invoke DispatchCreate and DispatchSetFormat.

    What may cause this behavior?
