All large companies have begun to adopt HTML 5 instead of Flash as a video player .
Facebook has moved to HTML5 by default in all browsers for web videos that appears on its News Feed, Pages and the embedded Facebook video player.
Setting Adobe’s Flash aside for video marks a significant change for the company, which built its first HTML5 video player five years ago. Back then it only supported iPhones and iPads, but retained Flash for other mobile browsers due to it outperforming HTML5.
Despite seeing promise in HTML5 for video, Facebook has outlined the numerous challenges that have kept it from making a complete switch from Flash across all platforms.
“In theory, most browsers in use support HTML5 video. However, in practice we noticed that a lot of the older browsers would simply perform worse using the HTML5 player than they had with the old Flash player. We saw more errors, longer loading times, and a generally worse experience,” Facebook engineer Daiel Baulig wrote in a blog post last week.
