YouTube is now using HTML5 video on all web browsers that can support it, though it will continue to use Flash video for browsers without suitable HTML support. On my computer, Google Chrome and Safari now use HTML5, while Firefox and Opera use Flash. But Firefox should use HTML5 before long. To see whether some video is in HTML5 or Flash, right-click or control-click on it. A popup menu should appear. If the video is in Flash, you should see some Flash options.



Being good for YouTube required the addition of variable bitrate and encryption. The latter is good for Digital Restrictions Management, er, Digital Rights Management (DRM). Not only YouTube, but also Vimeo and Netflix and possibly other online video sites are moving to HTML5. Also, both Apple and Microsoft now support it.



What's next for Flash?



There was already some trouble for it a few years back.

Did Steve Jobs kill Adobe Flash? - CNN.com "Flash is a spaghetti-ball piece of technology that has lousy performance and really bad security problems."

Steve Would Be Proud: How Apple Won The War Against Flash | TechCrunch Flash for Android briefly came and went.

Then Steve Jobs's famous 2010 Thoughts on Flash He listed what he considered 6 major problems.

1. Openness.

2. The Full Web.

3. Reliability, security, and performance.

4. Battery life.

5. User interface: "Touch".

6. Not taking full advantage of iOS.



#6 seems a bit like protectionism, and #5 represents something that Apple itself had overcome with Cocoa, creating the smartphone-friendly Cocoa Touch user-interface widgets. #3 and #4 are rather damning, suggesting either that Adobe's management doesn't consider those items high priorities, or else that Flash has some difficult-to-overcome architectural flaws. #2 is about Flash potentially being superfluous for online video, something that is now happening. About #1, SJ concedes that Apple has plenty of proprietary products, but prefers open standards about what's on the Internet.





Without video, Flash could retreat into being a platform for online animations and games. But even there, it may be possible for the HTML5-CSS-JavaScript troika to challenge it. HTML5 includes the "canvas" and "svg" elements, and both of them are usable for online animations and games.



Canvas: raster graphics, like a paint program

SVG: vector graphics, like a draw program (SVG = scalable vector graphics)
