Major Manufacturers Dropping MJPEG

Author: Ethan Ace, Published on Nov 04, 2016

MJPEG has hung on for years, still in use in some systems despite H.264's dominance for the better part of the past decade. However, now some manufacturers have removed MJPEG from their cameras and recorders, forcing users to stream H.264.

We look at this issue, products potentially affected, and its impact on applications in this note.
