http://techcrunch.com/2010/05/01/h-264-66-percent-web-video/ H.264 has already won, makes up 66% of online videos, and Adobe Flash encoding plummets Sunday, May 02, 2010 "Earlier this week, Steve Jobs kicked the debate about the need for Flash into high gear, especially for Web video," Erick Schonfeld reports for TechCrunch. "So how much video exactly is available in H.264? I asked Encoding.com, which has encoded 5 million videos over the past year for a variety of Websites and customers," Schonfeld reports. "In the past four quarters, the H.264 format went from 31 percent of all videos to 66 percent, and is now the largest format by far. Meanwhile, Flash is represented by Flash VP6 and FLV, which combined represent only 26 percent of all videos. That is down from a combined total of 69 percent four quarters ago. So the native Flash codecs and H.264 have completely flipped in terms of market share." Schonfeld reports, "Another data point that Steve Jobs mentions: All YouTube videos are available in H.264, which alone represents 40 percent of all videos on the Web. So these numbers from Encoding don’t seem so crazy." EDIT: The conclusions in the original article seem questionable. Unless this post sparks interesting debate I'll have it removed.
