Chrome Working On JPEG Encode Accelerator With VA-API/V4L2 Support
Chrome already offers JPEG decode acceleration while this encode accelerator interface is intended for use-cases like still image capture directly within the web browser.
This JPEG encode accelerator interface is being initially implemented with the Video Acceleration API (VA-API) as is widely supported on the Linux desktop with Intel graphics or the Gallium3D VA-API work. VA-API has supported MJPEG hardware acceleration with Broadwell hardware and newer for faster encode performance. There's also V4L2 support being worked on as well.
The basic details via this commit.
