In Nexuiz svn, you'll now find a neat tool called "demotc.pl". It allows some sort of "cutting" of demos (actually, it works by speeding up the part you do NOT want by 100), and it can also insert capturevideo on/off marks.

Usage:

demotc.pl cut infile.dem outfile.dem time_start time_end
demotc.pl cut infile.dem outfile.dem time_start time_end --capture
demotc.pl uncut infile.dem outfile.dem (undoes cut's operation)
demotc.pl grep infile.dem "all-time fastest lap record with (.*)\n"

The latter looks for the given string in the demo, and prints whatever is inside parentheses (the .*).

A demo generated with --capture will set capturevideo 1 when the time_start comes, and capturevideo 0 at the end.

cool cool
can we have in the menu a demo section where you can play them and with buttons on the top or somewhere like "capture video On" , "capture video Off " , "stop demo" etc. uh just an idea for 2.5
i would be happy if the Demo menu of 2.3 will be back.. new guys wouldn't have problems in watching demos

Well, the demo menu should make a comeback at some time, just making it flexible is not that easy..

I added userbinds for 'toggle capturevideo' so you can bind them to a key and just enable/disable creating .avi files.

yes i have bind some cmds
just an idea to make it more comfortable for new guys

well the extra bind in the svn menu is a start. lets see what can be added till the new release
