[QUOTE="Joutungwu, post: 1091085, member: 147600"] I have to correct my previous comparison because i found out that Hardware Acceleration could be used with the LAV Filters as well. Running Software during the testing were: Common Windows services, MS Security Essentials, SmartDVB. SmartDVB is a great DVB-Applikation for desktop usage and makes comparisons like these easier for me. So here are the cpu usage results during h.264 decoding of BBC One HD (1920x1080) for different decoder settings with Enhanced Video Renderer: [LIST] [*]Microsoft DTV-DVD Video Decoder (v.12.0.9200.16426); HW Acceleration [B]on[/B]: [B][COLOR=#00ff00]1 [/COLOR][/B]to[B][COLOR=#00ff00] 5 %[/COLOR][/B] [*]LAV [COLOR=#00ff00][COLOR=#000000]Video Decoder (v.0.62.0); HW Acceleration [B]on[/B]; HW Decoder NVIDIA CUVID: [COLOR=#00ff00][B]3[/B][/COLOR] to[COLOR=#00ff00][B] 8 %[/B][/COLOR][/COLOR][/COLOR] [*]LAV Video Decoder (v.0.62.0); HW Acceleration [B]on[/B]; HW Decoder NVIDIA CUVID with "Adaptive HW Deinterlacing" (50p/60p) and "High Quality Processing" on: [COLOR=#00ff00][B]6[/B][/COLOR] to [COLOR=#00ff00][B]12 %[/B][/COLOR] [*][COLOR=#00ff00][COLOR=#000000]LAV Video Decoder (v.0.62.0); HW Acceleration [B]off[/B]: [COLOR=#ff0000][B]30[/B][/COLOR] to [COLOR=#ff0000][B]40 %[/B][/COLOR][/COLOR][/COLOR] [/LIST] [COLOR=#00ff00][COLOR=#000000][COLOR=#ff0000][COLOR=#000000]Now it seems that the LAV Filters could be a good alternative for the unavailable MS Decoders in Windows 8.x. The HW Acceleration for the LAV Video Decoder is turned off by default, so i recommend to turn it on if it is available. My (human) eyes can't see a video quality difference between "Adaptive HW Deinterlacing" turned on or off. In conclusion the unavailable MS Decoders could be replaced by LAV Filters after changing from Windows 7 to Windows 8.x.[/COLOR][/COLOR][/COLOR][/COLOR] [/QUOTE]
