Win7 system N card, A card HD hard solution playback optimal settings

win7 problems, and most of them in the win7 installation and sound. I don't know how to enable the hard copy mode of HD video in Win7, because the same settings are very different under XP and Win7. This article summarizes the best setting scheme for Win7 system N card, A card HD hard solution playback. In this way, it is not difficult to set the optimal state of the Win system N card and the A card HD hard copy. The specific operation is as follows:

Step 1: How to harden the playback of MPEG2 video to start "Perfect decoding 20091225 version" set the center. If it is an N card, the decoding mode seeks to play HDTV (Nvidia PureVideo) “ and cancels the "automatic mode"; if it is an A card, then the HDTV (ATI UVD) is played, and cancels the "auto mode" ”. The main player finds kmplayer<quo;; video renderer finds VMR9 no rendering (correct black level) & rdquo;; MPEG2 TS/PS splitter seeks Haali<;&&&&&&&&&&&&&&&&&&&&&&" The decoder looks for Sonic“. Then run the perfect decoding test MPEG2 HD video & rdquo; sample.mpg“. Press the Tab key to display the playback information. The output mode is “DXVA”; the CPU usage is 5%, which means that the hard solution is successfully enabled.

Step 2: How to harden the playback of H.264 video to start the perfect decoding setup center. For the N card, the decoding mode seeks HDTV (Nvidia PureVideo) & rdquo; and cancels the "Auto mode"; if it is A card, it should play HDTV (ATI UVD) & ldquo; and cancel the "Auto mode" “. The main player seeks kmplayer>; video renderer finds EVR enhanced rendering (C/A) "; AVI splitter and MKV splitter both seek Haali"; H.264 video decoder seeks CyberLink (DXVA) & ldquo;; audio The decoder looks for CyberLink”. Then run the perfect decoding, open the HD video file “ HD car show. Mts” for testing. Press the Tab key to display the playback information. The output mode is “DXVA”; the CPU usage is 6%, which means that the hard solution is successfully enabled.

Step 3: Enable A-card hard-release playback VC-1 video to start the perfect decoding setup center, decode mode to find HDTV (ATI UVD) & ldquo;, and cancel the following  automatic mode“; The main player finds kmplayer>; the video renderer finds VMR9 without rendering (correct black level) "; AVI splitter and MKV splitter both seek Haali"; VC-1 video decoder seeks CyberLink (DXVA) & ldquo;; audio decoding Looking for CyberLink”. Then run the perfect decoding, open the video file “ HD album. Wmv” test. Press the Tab key to display the playback information. The output mode is “DXVA”; the CPU usage is 14%, which means that the hard solution is successfully enabled.

Which kinds of renderers support VC-1 hard copy playback?

In addition to the "VMR9 no rendering (fixed black)" renderer, "VMR9 no rendering" and "override synthesizer (default) & rdquo; mode also supports VC-1 hard solution .

Step 4: Use WMP12 hard solution to play VC-1 in the "perfect decoding" setting, VC-1 video decoder to find Microsoft ", and enable hardware acceleration function, can enable N card VC -1 hard solution. However, after the actual measurement, the N card plays VC-1 unstable in Win7, and often cannot be hard solved or error. Switching to the WMP12 that comes with the system is the simplest solution. Start WMP12, click & rdquo; Tools & ldquo; & rarquo; & rdquo; Options & ldquo; & rarquo; & rdquo; performance & ldquo;, tracing the DirectX video acceleration (X) enabled WMV file. Then open the “ HD photo album. Wmv” Test playback fluency. In the "Task Manager" view, the CPU usage of the WMP12 playing VC-1 video is about 5%, which indicates that the VC-1 hard solution is successfully enabled. (
