Mplayer i postprocessing raz jeszcze.

[Jacek Sobczak]

Po przeczytaniu wątku z początku maja spróbowałem uruchomić u siebie
postprocessing w mplayer. Skompilowałem go bez wykrywania CPU przy
starcie licząc, że zacznie działać. Niestety dostaję co następuje:

[sopel w speedy Matrix]$ mplayer -vo xv -pp 63 matrix.avi

Zastanawiają mnie trzy podkreślone fragmenty:

Po pierwsze to SSE? W logu zamieszczonym przez Marcina Wojtczuka jest co innego:
> Testing OS support for SSE... yes.
> Testing OS support for SSE unmasked exceptions... yes.
> Tests of OS support for SSE passed.
Jak to uzyskać? Zależy to od karty video? Ja mam Intel 815. No ale to
chyba kwestia procesora (Pentium III).

Potem ta rzecz dotycząca RTC. Jak na to zezwolić dla zwykłego usera?

No i ostatecznie brak postprocessingu - może ma to związek z tym SSE?

Dodam, że jest to samo przy -vo xv, sdl czy x11.
