When people buy a computer or laptop with a video card that supports hardware acceleration of the HD video stream, they often face the problem of significant inhibition when viewing video files that have the MKV extension. To fix this annoying flaw, you need to know how to enable hardware acceleration. It will be able to solve your problem once and for all.
This feature is present in most modern video adapters that are equipped with computers and laptops. Let's first figure out how this works, and then I'll talk about how to enable hardware acceleration. This option can transfer the processing of the video stream to the video card from the central processor of the computer. This reduces the overall system load. It also increases even the battery life, and it is also possible to play Full HD video, which is not able to be processed normally by many models of the younger dual-core “stones”.
Before enabling hardware acceleration, we need to make sure whether this feature is supported by a laptop or computer. We specify which model of the video adapter is installed in the device. This is done by calling the start menu, in which you need to run the runtime application and enter the following command in it: dxdiag. When the DirectX Diagnostic Tool window appears , go to the display tab.
Now you need to make sure that the equipment belongs to the appropriate generation. For IT, this is a series of HD 2xxx and higher; for NVidia, this is GForse 8 and higher. As for the Intel GMA video devices, this acceleration is not fully supported in them.
So how to enable hardware acceleration? First you need to install the latest drivers for the video card. They can be found on the official websites of manufacturers. After this step is completed, download and install a special codec on your computer, which includes the Media Player Classic. This codec is called K-Lite Mega Codec Pack. When you install this software, in the installation window you must select an option called Lots of Stuff. As soon as the installation is completed, the computer must be restarted, after which we launch the above player and go to the view menu, go to the options and select the internal filters.
In the window that opens, in the right part of it, you should check the box opposite the Matroska format, as well as H264 / AVC (DXVA) and VC1 (DXVA). Next, in the Playback and Output functions section, you need to set a "default system" for each of them. If in the future you wonder how to disable hardware acceleration, do everything in the reverse order. Now you can check your actions.
Run MKV video in a new player, open the task manager. Go to the performance tab and see how much your CPU load has decreased. Just do not confuse Chrome hardware acceleration with this action. This is completely different and is a topic for another discussion.
