[theora] Why Our Civilization's Video Art and Culture is Threatened by the MPEG-LA

Hi All,

On camera issue

few additional thoughts.

there are efforts to create open source camera


and as we know - digital camera is well suited to capture video ( many
cams have camcoder feature ).

then, next step it looks like  on 4 core Cortex-A9 MPCore   it is
possible to encode even 1080p video.

so the steps could be - look closely at arm codec, help to develop
multithreaded capability, contact those developing open source camera
and combine video encoding part with their efforts.

another issue might be moving step by step: offer net web cam
producers ability to stream in theora ( though fixing rtsp stream will
be needed ) - at least - the more theora is used, the better.

as for patent claims - so far nothing except threats.

basic features - like DCT, I frames, motion estimation etc - are well
outside patent time frame.
then VP3 appeared in 2000 - so any futher patents will have a well
established prior art.

now - there are no known patents since 1993 to 2000 which VP3/theora
might infringe.

so let us wait and if any threat - fight.

but - the idea to create open source camcoder should move and theora
is a great candidate for being a base codec for that.
