With a combination of a slightly modified nuppelvideo port, a buffering script and mencoder it is possible to capture and compress to AVI from a bktr tuner at full PAL resolution (768x576) *with make buildworld running* on an AMD2000+ - and probably on much less powerful hardware, certainly if you don't run make buildworld while recording :) The test run dropped a few frames, which it seems can be avoided if the make buildworld is run under nice :) The bits to make it happen can be found on ftp.sohara.org in /pub: nuppelvideo.1.1-1.2.patch Patch for nuppelvideo port to enable using stdout. nuppelvideo.tar.gz Version of the Nuppelvideo port with this patch applied.
