Hi to All,

After the upgrade from Windows 8 pro to Windows 8.1 pro (i have done a fresh installation of Windows 8 pro and then i have upgraded to windows 8.1 pro) i get that ffmpeg.exe (64Bit version) uses all cpu ( Near to 100%) and i get in mezzmo the alert that the video conversion is too slow (under 23 fps).
I have installed the latest version of mezzmo available.

Before upgrading using the same pc with windows 8 pro i did not get this behavior. In this situation i got that ffmpeg process has used "only" 60% of cpu.

Another strange behavior is that if i stop to watch the movie (for example i stop the movie from the tablet) i get that in windows the ffmpeg.exe process is not stopped but it continues to transcode the movie . before this test I have unchecked the option to get that all the conversions in backgroud must be stopped.

Could you please help me to understand what is changed?

thanks for your help

Besta regards
