What made HTML successful?

• Anyone could publish to the web
• Anyone could build tools

Apply to Video

• Allow anyone to produce and contribute video
• Allow anyone to build tools

How to do this?

• Dedicated HTML markup
• DOM interfaces specific to video
• As easy as using <img>
• Scripting not required but supported
• Integrate into rendering pipeline

How can anyone build tools?

• Baseline codec to work across all implementations
• No royalties required to create encoders/decoders
• Open source reference implementations
• Javascript, DOM and HTML on the client side

WHATWG <video> Proposal

• Specification for <video>
• Based on public discussion and feedback
• Multiple browsers working on implementations
• (Firefox, Webkit, Opera)
• Need to define a baseline codec

Codecs

• Anyone can implement
• Anyone can freely distribute
• Royalty free patent licensing
• Baseline codec must be supported
• Other codecs can be optionally supported

Codecs - Ogg Vorbis and Theora

• Ogg is the container
• Vorbis is the audio codec
• Theora is the video codec
• Open source BSD-style licensed implementation
• Firefox and Opera have experimental implementations

Codecs - Issues to be solved

• Patent Risk
• License payments
• DRM
• Is a baseline codec needed?
