What are VDPAU drivers?
The VDPAU interface is to be implemented by device drivers, such as Nvidia GeForce driver, nouveau, amdgpu, to offer end-user software, such as VLC media player or GStreamer, a standardized access to available video decompression acceleration hardware in the form of application-specific integrated circuit (ASIC) blocks …
What is Libva VDPAU driver?

How do I enable MPV hardware acceleration?
mpv. mpv has good hardware acceleration support, although it is not enabled by default. To enable it, use the –hwdec command line switch. It can also be made the default by adding a line like “hwdec” to the mpv configuration file (e.g., $HOME/.
What is hardware accelerated video decode?
Hardware video acceleration makes it possible for the video card to decode/encode video, thus offloading the CPU and saving power. Video Acceleration API (VA-API) is a specification and open source library to provide both hardware accelerated video encoding and decoding, developed by Intel.
What is GPU decoding?
By leveraging the video graphics card to decode video and keeping the CPU available for other processes to run the system, GPU decoding makes it possible to display a greater number of cameras using off-the-shelf graphics hardware, and without having to invest in additional workstations.
How do I enable Vaapi?
Enable or disable VA-API in Firefox
- Start by launching Firefox.
- In the preferences search bar, type vaapi .
- Once it’s been toggled on (or off, if you prefer), close all Firefox instances and open the browser back up.
Can mpv play HDR?
mpv has an OpenGL, Vulkan, and D3D11 based video output that is capable of many features loved by videophiles, such as video scaling with popular high quality algorithms, color management, frame timing, interpolation, HDR, and more.
Where is mpv config?
According to mpv’s documentation, the CONF file is stored in the “\AppData\Roaming\mpv”.
How do I get unlimited fps in Chrome?
Adjust the frame cap to “0” or “1200” (both will provide unlimited FPS since the game is capped at 1200 currently). In settings, search “FPS”. Check the “Unlimited FPS” box. The client will now restart and unlimited FPS is enabled.
How to use VDPAU on an AMD Radeon?
Systems using an AMD Radeon graphics driver will need to do the following. By default applications such as mplayer,vlc,vdpauinfo,… make VDPAU specific calls via libvdpau library. This library then dynamically loads appropriate back-end driver ( VDPAU driver specific to your hardware read more… ).
Are there any open source drivers for VDPAU?
ATI/AMD released an open source driver for Radeon HD 4000+ graphic cards featuring VDPAU acceleration. Intel does not offer VDPAU drivers, they only support their VA-API. It is, however, possible to use Intel’s VA-API drivers by way of libvdpau-va-gl .
How to use VDPAU as a back-end driver?
By default applications such as mplayer,vlc,vdpauinfo,… make VDPAU specific calls via libvdpau library. This library then dynamically loads appropriate back-end driver ( VDPAU driver specific to your hardware read more… ). At the time of writing the mechanism to automatically decide which back-end driver needs to be loaded was not established.
When did Nvidia release VDPAU version 1.0?
On March 9, 2015, Nvidia released VDPAU version 1.0 which supports High Efficiency Video Coding (HEVC) decoding for the Main, Main 4:4:4, Main Still Picture, Main 10, and Main 12 profiles. VDPAU is implemented in X11 software device drivers, but relies on acceleration features in the hardware GPU.
