mam problem - trhane video ked ho prehravam na fullscreen. Ci uz je to v mplayeri, toteme alebo vlc. Ci je compiz zapnuty alebo nie je. A to mam VGA i945, ktora by mala byt podporovana bez problemu. Nasiel som na forach info ze s tym ma problemy vela ludi. Otazka je ci sa snazit to riesit (uz hladam ale 2 dni riesenie a bez vysledku) alebo jednoducho to nepojde?
V zobrazeni v okne pri 100% to netrha. Len ked je okno vacsie alebo na fullscreen tak pri rychlejsich scenach to horizontalne trha (ako ked v hrach nebolo nastavene vertical synch.). V compiz nastaveni som skusal zapnut/vypnut volby "sync to vblank", ale bez vysledku.
moj hw je Dell Optiplex 620 P4 3GHz, 2.5GB DDR2, i945, Ubuntu 8.10
Intel 945 a trhane video v ubuntu

i945 sú 2 typy - laptop a pre PC
Preto sa pozri do "xorg.conf", ako ti detekovalo graf. kartu-chipset a napíš.
možno tam je problém.

A ide normalne. Je to mpeg4 ale napr x264 v 720p uz mi seka (mam 1.6 GHz intel atom a na to vraj 720p treba 1.8 GHz core duo alebo 3 GHz pentium 4)
Mozes poskytnut vzorku toho videa? Staci povedzme 10s
mencoder -oac copy -ovc copy -ss 5:00 -endpos 30 vstup.avi -o sample.avi
-ss 5:00 je posun na 5 minut
-endpos 30 znamena ze vyrezat 30s

vo viste na tom istom stroji to ide ok, cize to nie je hw problem
- cista instalacia 8.04
- odkomentovanie zakomentovanych veci v /etc/apt/sources.list
- sudo apt-get update
- nainstalovanie aktualizacii
- doinstalovanie kodekov podla navodu na medibuntu (pozor na spravnu verziu ubuntu!)
- sudo apt-get install mplayer
Takto som instaloval vsetky pocitace a na vsetkych kde bola intel karta to takto islo. Ziadne dalsie veci nedoinstalovavam.
