VDPAU on Radeon R600 and newer GPUs is supported by mesa-vdpau.ĪMDGPU PRO proprietary driver is built on top of AMDGPU driver and supports both VA-API and VDPAU in addition to AMF.VA-API on Radeon HD 2000 and newer GPUs is supported by libva-mesa-driver.
#Steam link hardware encoding amd drivers
VDPAU on GeForce 8 series and newer GPUs ĪMD and ATI open-source drivers support both VA-API and VDPAU:.NVIDIA proprietary driver supports via nvidia-utils: Requires nouveau-fw AUR firmware package, presently extracted from the NVIDIA binary driver.GeForce 8 series and newer GPUs up until GeForce GTX 750 are supported by libva-mesa-driver and mesa-vdpau.Nouveau open-source driver supports both VA-API and VDPAU: Skylake or later also need linux-firmware.Īlso see VAAPI supported hardware and features.Haswell Refresh to Skylake VP9 decoding and Broadwell to Skylake hybrid VP8 encoding is supported by intel-hybrid-codec-driver-git AUR.GMA 4500 H.264 decoding is supported by libva-intel-driver-g45-h264 AUR, see Intel graphics#Hardware accelerated H.264 decoding on GMA 4500.GMA 4500 (2008) up to Coffee Lake (2017) are supported by libva-intel-driver.Intel Arc) are supported by intel-media-driver. HD Graphics series starting from Broadwell (2014) and newer (e.g.Intel graphics open-source drivers support VA-API: NVDEC/ NVENC - NVIDIA's proprietary APIs for hardware video acceleration, used by NVIDIA GPUs from Fermi onwards.įor comprehensive overview of driver and application support see #Comparison tables.Advanced Media Framework (AMF) is an open source framework which allows "Optimal" access to AMD GPUs for multimedia processing using the AMDGPU PRO Stack, Developed by AMD.Video Decode and Presentation API for Unix (VDPAU) is an open source library and API to offload portions of the video decoding process and video post-processing to the GPU video-hardware, developed by NVIDIA.Video Acceleration API (VA-API) is a specification and open source library to provide both hardware accelerated video encoding and decoding, developed by Intel.There are several ways to achieve this on Linux: I assume x264- CPU encoding would need a very strong processor to both run the game well and encode at same time.Hardware video acceleration makes it possible for the video card to decode/encode video, thus offloading the CPU and saving power. But it(Quck sync) provides best results at present. CPU encoding is x264, while Intel Quick Sync is also hardware encoding. The latency maybe because of the extra longer path, in case of hardware encoding,it communicates to your external GPU.Ĭorrection. you may be better off using CPU/H264 encoding. If your CPU is high end, your game is not very demanding and it is not doing any other background tasks. For example, the 30 series RTX cards have decent NVENC chips.
However, the dedicated GPU chip is different across different generations of GPU. The rationale behind using hardware encoding is that it frees up the CPU from doing it and dedicate resource towards gaming. In absence of hardware encoding, the computer will rely on CPU- internal GPU encoding. It does not come into factor for the gameplay, it is dedicated chip for this use only. The hardware encoding decoding chip is seperate on GPU.
