TV-Out na Matrox G400 DualHead

[Vlada Macek]

Sen:

    Xka na monitoru pro normalni praci, nezavisly vystup videa vc.
    titulku na druhem konektoru do televize. Je to vubec technicky
    mozne? Pokud ano, jak jste toho dosahli?

Konfigurace:

    Matrox G400 DualHead, Debian Sarge jadro 2.6.8-2-686 z balicku, Xka
    1600x1200, D: 229.516 MHz, H: 106.257 kHz, V: 85.006 Hz

Situace:

Zatim jsem ve stavu, kdy mi TV-Out mi "nejak funguje". Pri bootu delam:

    mknod /dev/mga_vid c 178 0  
    chown root:video /dev/mga_vid
    chmod 0660 /dev/mga_vid  

    modprobe mga_vid
    modprobe i2c-matroxfb
    modprobe matroxfb_maven
    modprobe matroxfb_crtc2

Coz mi z konzole udela pokazde  jinou zmet barevnych bodu, takze zivorim
v Xkach bez moznosti konzole. Pomoci prilozeneho skriptu poustim filmy.

Ten skript jsem vydestiloval z ruznych navodu na netu a ze skriptu ve
zdrojacich mplayeru. Pomoci -vf expand=0:x:0:y nastavuju hodnoty pro
kazdy film tak, abych nemel kolem filmu rozhazene smeti, jen cerne pruhy.

Po skonceni filmu zustane video v Xkach v nejakem divnem stavu a musim
nekolikrat prepnout CtrlAlt+-. Pak musim vynutit prekresleni aplikaci,
abych zrusil pozustatky, ktere samy uplne nezmizi.

Jak jiste uznate, je to znacne neprakticke. Je mozne dosahnout
prehravani videa na druhem vystupu karty za soucasneho zcela nezavisleho
fungovani v Xkach? To by bylo idealni. Ocenim vsak i prispevky k me
soucasne situaci, jak ji zlepsit.

Diky predem za rady!
