IWMWriter::EndWriting() hanging in vista for bigger files RRS feed

  • Question

  • I'm using IWMWriter to save a WMV movie and it is hanging when writing out files > about 2 megs when I call EndWriting(). The same program works fine in XP.

    Is IWMWriter supported in Vista? How would I go about debugging this problem?

  • Becky: thanks for your reply!

    The problem happened to be that I was using the WMSDK 9 dlls, which are not supported on Vista.

    Now I'm no longer linking or copying the WMSDK dlls. Instead, I'm just calling LoadLibraryEx and GetProcAddress to use whatever Windows Media the user has currently installed.
