    Description

      I use Qt 4.7.3 to write an Video player based on Phonon::VideoWidget to play AVI files (with Motion JPEG codec). The player works fine in XP SP3 and Win7. However, in Vista, only sound is played and no video shows (only freeze picture of previous screen). Both mingw and vs2008 versions have the same problem.

      I also tried the demo program qmediaplayer and got the same result. The aspect ratio is not correct and the windows is froze after selecting an AVI file.

      I have tried to recompile phonen and phonon_backend with DirectX 2010 June. The DLLs are successfully built but the player still can't play video (Motion JPEG) in Vista.
