Dotaz: SAA7133/SAA7135

[ziki18]

Zdravim. Do ruky sa mi dostala TV karta :

00:0a.0 Multimedia controller: Philips Semiconductors SAA7133/SAA7135 Video Broadcast Decoder (rev d1)
        Subsystem: KWorld Computer Co. Ltd. Unknown device 7253
        Flags: bus master, medium devsel, latency 32, IRQ 18
        Memory at ea010000 (32-bit, non-prefetchable) [size=2K]

Moduly sa mi zaviedli automaticky:

V /dev/ mam vytvorene :

$ ls /dev/ | grep video
video0

Dalo by sa to neakym programom vyskusat okrem xawtv. Ten mi tam nesiel. A distro je MythBuntu 7.10. V kdetv sa mi zobrazi iba cierna orazovka.

A skusal som aj tvtime

# tvtime-scanner

    No tuner found on input 0.  If you have a tuner, please
    select a different input using --input=< num >.

Možná se kouknout do logu zda to správně poznalo kartu zda se tam při ladění neoběvují errory - potom by to chtělo zavádět modul s parametrama....

Jinak co třeba mplayer ?

mplayer tv://E5 -tv driver=v4l2 místo E5 zadej tvůj kanál který chceš přijímat.

Jinak tvtime, kdetv.

No nepoznalo to kartu třeba zadat správný parametr card=x a možná to je problém pak neví jaký tuner tam je a skolabuje to.

přesně jak je výše. nepoznalo to tu kartu. musí vám to ukázat něco jako

[   37.420152] saa7130/34: v4l2 driver version 0.2.14 loaded
[   37.420266] saa7133[0]: found at 0000:00:0c.0, rev: 209, irq: 19, latency: 32, mmio: 0xe6001000
[   37.420276] saa7133[0]: subsystem: 1461:f01d, board: Avermedia Super 007 [card=117,insmod option]

pro to je třeba zadat do parametru modulu příslušné číslo karty. u mě (ubuntu/avermedia) to znamená do /etc/modprobe.d/options dopsat řádek "options saa7134 card=117 tuner=55". dokud to nebude vědět jaká karta to je, nic nepůjde naladit!
