Crno-beli svet (Leadtek WinFast tv2000 xp expert)

^{29.10.2005. u 00:11 - pre 224 meseci}

Pozdrav,
U naslovu navedena tv kartica (Leadtek WinFast tv2000 xp expert), u odnosu na predjasnje tri tv kartice, koje sam pokusavao da doteram da rade pod Linux-om, pokazuje vise "zivosti", ali ipak ne i dovoljno da bi bio potpuno funkcionalan.

Pre nego sto me neko uputi da pretrazim forum za starijim temama, evo spiska tema na ovom forumu koje sam procitao:

http://www.elitesecurity.org/tema/6900/0
http://www.elitesecurity.org/tema/135314/0#881123
http://www.elitesecurity.org/tema/57878/0#369986

Pokusao sam verovatno sve sugestije (mala je verovatnoca da mi je nesto bitno promaklo) u navedenim temema, ali bez uspeha.

Naime u pitanju je, verovatno, uobicajen problem da je slika crno-bela, ali ne samo u "tvtime" programu vec i u programu "zapping" ("xawtv" i nakon uspesne detekcije kanala komandom `scantv -o .xawtv` i izborom "2: PAL-BG" i "6: europe-east", odbija da prikaze bilo sta drugo osim plavog ekrana).
Ako se neko mozda pita sta je sa zvukom, u pocetku ga nije bilo, ali sam onda povecao jacinu tona u "Volume Control" programu, CD izlazu, i od tada je zvuk u redu.

Karticu je sistem (ubunutu, hoary 5.04) pronasao i pravilno oznacio:

Code:

$ lspci -vv
...
0000:00:0e.0 Multimedia video controller: Conexant Winfast TV2000 XP (rev 05)
        Subsystem: LeadTek Research Inc.: Unknown device 6611

        Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR-

        Region 0: Memory at e5000000 (32-bit, non-prefetchable) [size=16M]

...

takodje je i ucitao, po mom misljenju, potrebne module jezgra:

Code:

$ lsmod | grep -i cx
cx8800                 29196  1
cx88xx                 46868  1 cx8800

ide_core              118988  4 ide_cd,ide_generic,via82cxxx,ide_disk

dok `dmesg` prikazuje sledece, opet ako se ne varam, pravilno:

Code:

$ dmesg
...

...

koji, nakon nekog vremena prikazuje sve vise linija, nalik sledecim:

Code:

$ dmesg
...
cx88[0]/0: AUD_STATUS: 0x1132 [mono/no pilot] ctl=BTSC_AUTO_STEREO
cx88[0]/0: AUD_STATUS: 0x17b2 [mono/no pilot] ctl=BTSC_AUTO_STEREO
cx88[0]/0: AUD_STATUS: 0x1df2 [mono/no pilot] ctl=BTSC_AUTO_STEREO
...

U Knoppix-u 3.8, izlazi programa ("lspci", "lsmod" i "dmesg") su uglavnom, u delu koji se neposredno tice kartice, isti, s tim sto u Knoppixu "xawtv" prikazuje sliku _sa_ bojom, iako se zvuk cesto poremecuje.

Da li neko ima neki predlog, za povratak boje na tv slici, od ove tv kartice?
