[QUOTE="anony, post: 856889, member: 86664"] In the past I used ffdshow DXVA and could get hardware acceleration when playing MPEG4 avi files, but recently I installed MediaPortal 1.2.2.0 and it seems to have lost this ability, even though I selected "ffdshow DXVA video decoder" in Codecs and Renderer in MediaPortal. I did select EVR under Video Renderer settings and in ffdshow DXVA options I checked "DXVA codecs enabled: H264 / VC1", just like before. I see "LAV Video Decoder" in my list of codecs, which someone else said may break DXVA, but I'm not sure if that's true: [url]https://forum.team-mediaportal.com/threads/please-stop-including-lavfilters-in-plugin-it-breaks-my-dxva-acceleration.106449/[/url] [Update: I removed LAV Video Decoder which was a part of the CCCP package, which I used to enable ffdshow in Windows 7. That didn't help enabling DXVA] Anyone has a clue? ...well, I'm not sure if I am getting acceleration or not. It seems like I'm not because I don't see the ffdshow DXVA logo in the start menu when I play videos in MediaPortal, and my CPU usage stays at 99-100%. My videos don't seem to be stutter at the moment, but that might just mean the CPU is powerful enough to play the scene at the moment. [/QUOTE]
