About Hardware Acceleration#
This topic discusses the platforms and the codecs for which hardware acceleration is supported.
How To Enable Hardware Acceleration#
See Hardware Acceleration for an example on how to enable the hardware accelerated codecs in your code.
Supported Codecs#
HEVC / H.265 Encoding#
Hardware acceleration for HEVC H.265 video encoding is currently supported only on NVIDIA 2nd generation Maxwell GPUs.
AVC / H.264 Encoding#
Hardware acceleration for AVC / H.264 video encoding is supported on Intel CPUs with Intel® Iris and Intel® HD Graphics technology, NVIDIA GPUs, and AMD GPUs and APUs.
Hardware Platforms#
Hardware acceleration is supported on following platforms:
Intel® Quick Sync Video (QSV) on Windows
NVIDIA NVENC fixed-hardware encoder on Windows
AMD Video Coding Engine (VCE) on Windows
Intel® Quick Sync Video#
Intel® QSV is available on select Intel processors with integrated Intel® Iris and Intel® HD Graphics technology. To use Intel® QSV, you must install the correct Intel® HD Graphics Driver for Windows.
If you are uncertain which Intel® Processor is in your computer, we recommend using the Intel® Processor Identification Utility or Intel® Driver Update Utility to identify your Intel Processor.
Available on:
Intel® Core 3rd, 4th, 5th, and 6th generation processors
Intel® Core M processors
Intel® Celeron processors with Intel® QuickSync Video
Intel® Pentium processors with Intel® QuickSync Video
Intel® Atom processors with Intel® QuickSync Video
