Hello,

Since the video codec issue has been reopened I'd like to make a quick
comment. 

http://lists.w3.org/Archives/Public/public-html/2009Jul/0408.html

Vorbis and Theora being lossy codecs, reusing them over and over would
result in poor quality.

Adding fade in/out attributes to the audio/video elements, would make it
possible for content creators (everybody) to reuse vorbis/theora files.
They could cut the files without re-encoding
and HTML fade in/out would smooth out the ends. 

With copyright license permitting, all the vorbis/theora media on the
Web would become reusable media objects.

The idea for fade in/out attributes comes from SMIL.
SMIL 2 had fade in/out for visual media, SMIL 3 added it for audio:

Thanks for re-opening video.

Jose
