I have tried these tests using both ffdshow and CoreAVC codecs in both MediaPortal, GraphEdit and MediaPlayer Classic. What i've found is that MediaPortal doesn't seem to use as much of the hardware accleration in my ATI 2600 Pro card as MediaPlayer Classic does using the same codecs playing the exact same files. Its very confusing. Here's some stats etc when i play a 720p and 1080p file using CoreAVC codec through MediaPlayer Classic and then the same thru MediaPortal on my Windows XP set-up. Heres the results through MediaPlayer Classic: [U]720p MKV File[/U] 1280 x 528 5853 bitrate MPEG4-AVC Video 5.1 AC3 Audio CPU Usage: 25% GPU Usage: 45% [U]1080p MKV File[/U] 1920x800 10675 bitrate MPEG4-AVC Video DTS Audio CPU Usage: 55% GPU Usage: 65% Heres the results through Media Portal: [U]720p MKV File[/U] 1280 x 528 5853 bitrate MPEG4-AVC Video 5.1 AC3 Audio CPU Usage: Upto 35% GPU Usage: Upto 17% [U]1080p MKV File[/U] 1920x800 10675 bitrate MPEG4-AVC Video DTS Audio CPU Usage: Upto 70% GPU Usage: Upto 30% So as you can see, by playing the 1080p files through MediaPlayer Classic I get a 15% reduction in CPU usage and a 35% increase in GPU usage compared to playing them through MediaPortal. Why is this? Why does MediaPortal use less of the hardware acceleration of my card compared to MediaPlayer Classic? Are there some settings that i need to apply in MediaPortal to enable the hardware acceleration? Any help, advice, tips and tricks would be very much appreciated. :thx: [/QUOTE]
