Not a great help because I can't remember any product names, but there is all sorts of 'home security cam' software that only records movement in the frame - I think they are taking advantage of some aspects of MPEG encoding to acheive this so you can end up with an MPEG that only includes the 'interesting' bits
not sure if there's anything FOSS that does this, the software I've seen was either part of a home security package or was otherwise propriety so, um, hope that helps, despite it's vagueness :) On Tue, May 19, 2009 at 9:41 AM, david <[email protected]> wrote: > There is a thing called zoneminder which I've played with but not used > seriously.
