Also the people form Elphel are working in a cinema camera:<br><a href="http://cinema.elphel.com/">http://cinema.elphel.com/</a><br><br><div class="gmail_quote">2010/5/4 Sergey Kurdakov <span dir="ltr"><<a href="mailto:sergey.forum@gmail.com">sergey.forum@gmail.com</a>></span><br>

<br>
On camera issue<br>
<br>
<br>
few additional thoughts.<br>
<br>
there are efforts to create open source camera<br>
<br>
<a href="http://news.stanford.edu/news/2009/august31/levoy-opensource-camera-090109.html" target="_blank">http://news.stanford.edu/news/2009/august31/levoy-opensource-camera-090109.html</a><br>
<br>
and as we know - digital camera is well suited to capture video ( many<br>
cams have camcoder feature ).<br>
<br>
then, next step it looks like on 4 core Cortex-A9 MPCore it is<br>
possible to encode even 1080p video.<br>
<br>
so the steps could be - look closely at arm codec, help to develop<br>
multithreaded capability, contact those developing open source camera<br>
and combine video encoding part with their efforts.<br>
<br>
another issue might be moving step by step: offer net web cam<br>
producers ability to stream in theora ( though fixing rtsp stream will<br>
be needed ) - at least - the more theora is used, the better.<br>
<br>
as for patent claims - so far nothing except threats.<br>
<br>
basic features - like DCT, I frames, motion estimation etc - are well<br>
outside patent time frame.<br>
then VP3 appeared in 2000 - so any futher patents will have a well<br>
established prior art.<br>
<br>
now - there are no known patents since 1993 to 2000 which VP3/theora<br>
might infringe.<br>
<br>
so let us wait and if any threat - fight.<br>
<br>
but - the idea to create open source camcoder should move and theora<br>
is a great candidate for being a base codec for that.<br>
<br>
