This Intel® Developer Zone document lists the media encode and decode capabilities for 7th generation Intel® Core™ processors and newer.
What is encoding/decoding?
Video content is typically compressed and encoded into a specific format when it's stored on hard drives, DVDs, Blu-ray* products, tablets, mobile devices, or broadcast media. When the content is played, uploaded on the Internet, or copied, it must first be decoded and then re-encoded into the relevant format for your browser, video application, or device.
The video encoding and decoding process uses video coding formats such as MPEG-4 Advanced Video Coding (MPEG-4 AVC or H.264), High Efficiency Video Coding (HEVC or H.265), VP8, and many more. These formats all adhere to standard specifications. The dedicated media processing capabilities of Intel® Graphics Technology decode and encode quickly, allowing the processor time to complete other tasks and improve system responsiveness.
