Zkus:

spcaview -o pokus.avi -s 640x480

[Gilhad]

S rozlisenim 640x480 spcaview udela okno s cimsi zelenym v horni casti (teda ony to jsou asi tak dve obrazy vedle sebe s dolni casti zmrsenou), pricemz pise mraky "cmcapture: Invalid argument"

S rozlisenim 320x240 to uz ukazuje dobre, ale ulozeny soubor neprehraje (cerne okno po prislusnou dobu) a mplayer to okno ani neotevre, i kdyz prislusnou dobu dole pocita framy .... prikladam zaznam jedne takove session ...
