On some of our systems (Windows) we get better MP4 playback performance in the CatDV client with Windows Media Framework instead of QT. Only real drawback is that clicking on the Set Poster button gives a "Thumbnail not created" error.
Of course, we could switch to FFMPEG or QT playback momentarily, create the poster, and then switch back. But I'm wondering if there is a way to get get poster/thumbnail creation working with WMF?
I'm 24 hours from putting this puppy into production environment...lots of work to get to this point! Just tidying up a few loose ends.
