IPTV Live Video Encoding & Streaming with Intel Quick Sync Video

Intel Quick Sync Video is powered by Intel CPU integrated graphics, which is available on most Intel Core processors starting with Sandy Bridge, and some Celeron & Pentium processors starting with Haswell. Visit Intel Product Specifications to find out if your processor is capable of Quick Sync Video.

Set up Intel Quick Sync Video Streaming on Windows

To set up Intel Quick Sync Video streaming on Windows, desktop OS like Windows 10 against server OS is recommended. Make sure to install latest Intel HD Graphics driver. Outdated video driver could cause unexpected encoding problems.

Set up Intel Quick Sync Video Streaming on Linux

Setting up Intel QSV on Linux platform is painful and we STRONGLY recommend NOT doing this. If you are using recent Linux distros like Ubuntu 22.04, it is lucky to have driver packages in release repos so you can just apt-get to install them. On older distros, you may need to download and build drivers from sources on your own. For detailed instructions, visit Intel Client GPU Installation.

After installation, enter vainfo in command console to make sure Intel driver working correctly. If not, try environment values LIBVA_DRIVER_NAME like iHD or i965. And set LIBVA_DRIVERS_PATH if driver files cannot be found.

Set up Intel QSV Video Encoding

IPVTL supports H.264, HEVC, MPEG-2, VP9 and AV1 encoding with Intel QSV. In channel config, choose encodings with qsv to enable it.

IPVTL Intel QSV Encoding

Note different Intel processors have different capabilities of video encodings. For example 9th/10th generation Intel Core processors (Intel UHD Graphics 630) supports HEVC/H.265 main profile only, while 11th (Intel UHD Graphics 750) and above generations support HEVC main and scc (screen content coding) profile. For details please visit Media Capabilities Supported by Intel Hardware.

Set up Intel QSV Video Decoding

If the channel source video is encoded in H.264, HEVC or AV1, it is recommended to enable QSV decode to make pure GPU transcoding. To do that, select QSV H.264 or HEVC (as per source video format) in advanced video options -> Misc. -> GPU Decoding. This will make video decoding, resizing and encoding process (with deinterlacing if required) all in GPU, avoiding unnecessary picture data copy between system memory and video memory.
