Does HTML5 video replace Flash?
The short answer is, no. There are several things for which Flash is the only op-
tion now, and some things for which HTML5 video is never likely to be an option.
Flash has support for Real Time Streaming Protocol (RTSP) and the Real Time
Messaging Protocol (RTMP), which provide facilities such as adaptive streaming,
switching the bitrate of the video stream as the available bandwidth varies, and
digital rights management (DRM).
It's possible that HTML5 video will one day support adaptive streaming, but it's
extremely unlikely that it will ever support any features for DRM in a cross-
browser fashion. If you want to use DRM on your video and audio content, then
you'll need to continue using Flash.
As you may have guessed, browser support for audio and video is
something of a thorny subject. Let's look at the details.
Support for both <video> and <audio> elements is universal across all
current browsers. The problem at this point is finding the minimum
number of different encodings for maximum browser compatibility.
