[Mplayer-felhasznalok] Re: fps problema

[Ivan Szanto]

 Hi,



koszi a valaszt.

> es ha -fps es -ofps is megadod?

nekem az -fps opcio ebben az esetben mar semmit nem valtoztat az mencoder
kimeneten.

probaltam a kovetkezoket:

meg tegnap (errol szol az elozo level)
mencoder -ofps 27.5 test.avi -o a -ovc lavc -lavcopts vcodec=msmpeg4:vbitrate=1800

mai probak -fps es -ofps megadasaval:

mencoder -fps 7.61 -ofps 27.5 test.avi -o a-fps7  -ovc lavc -lavcopts vcodec=msmpeg4:vbitrate=1800
mencoder -fps 27.5 -ofps 27.5 test.avi -o a-fps27 -ovc lavc -lavcopts vcodec=msmpeg4:vbitrate=1800
mencoder -fps 90   -ofps 27.5 test.avi -o a-fps90 -ovc lavc -lavcopts vcodec=msmpeg4:vbitrate=1800

utana:

{kvz063% szivan} cmp a a-fps27
{kvz063% szivan} cmp a a-fps7
{kvz063% szivan} cmp a a-fps90
{kvz063% szivan}

vagyis itt ugy tunik, mindegy, hogy megadom-e a -fps erteket, a kimenet
nem valtozik egy bitet sem.

sot, meg az stdout is majdnem ugyanaz, csak az aktualis tomoritesi
sebesseg ter el picit. A stdout eleje:

ettol kezdve az mencoder stdout-ok kulonboznek az fps-ben, de ez
a lejatszast persze nem befolyasolja, mert az eredemenykeppen
letrejovo file-ok bitre megegyeznek. Igy most nem is rakom be
ujra az mplayer -v outputjat, mert ugyanaz, mint az elozo levelben.

Megegyszer koszi, s ha meg van otleted, akkor meg foleg. ;-)
