I am trying to get alpha transparent videos working with openFrameworks, preferably with 0.8.1, but version 0.9.0 would also be fine. I am unable to get the VideoPlayerExample working. It compiles no problem but the video that is played is not transparent. I do uncomment the fingerMovie.setPixelFormat(OF_PIXELS_RGBA); line.
I am trying two different videos, one encoded with ProRes4444 and one with RLE.
Both of which works with the same example project when compiled in ofv_9 on MacOSX in Xcode 7. However when compiled in Visual Studio the videos play with a black background instead of what is supposed to display behind it.
My guess is that I do not have something configured correctly in Windows to let this work. However when I open both videos using QuickTime or MediaPlayer Classic they both run fine (with the default black background).
I have installed both the ProRes Decoder and the KLite Codecs.
What steps am I missing in order to get this the video to play correctly on Windows.
