Dotaz: Nahrávání z A/V in Pinacle 330e

[Lukáš Benda]

Ahoj,

prave se mi podarila rozchodit digitalni cast meho (uz dlouhou dobu meho) pinacle 330e, jedna se o hybridni USB TV tuner, ktery zvlada i analog, coz nemuzu vyzkouset, protoze sem v Praze, kde uz nic takoveho neni. Ale presto chci analog pouzit pro nahravani z UPC set topo boxu, ze ktereho mam analogovy vystup a tahle karta ma mini-usb a do neho se daji strcit analogove konektory (s-video i video-audio jack). Nevite nekdo jak tohle rozchodit na Pinnaclu?

P.S.: Chodi vam nekomu taky EPG s touhle kartou?

Tak sem zjistil ze se ten konektor jmenuje Composite a je dostupny na input=1 (resp.2 pokud chci pouzivat s-video). Ale stale se k signalu z toho mista neumi dostat.

Kdyz spustim mplayer dostanu dve chybove hlasky:

v4l2: ioctl query control failed: Invalid argument A taky: open: No such file or directory [MGA] Couldn't open: /dev/mga_vid open: No such file or directory [MGA] Couldn't open: /dev/mga_vid [VO_TDFXFB] This driver only supports the 3Dfx Banshee, Voodoo3 and Voodoo 5. [VO_3DFX] Unable to open /dev/3dfx.

Nevite jak tohle vyresit?

Takze na druhem pocitaci (s Gentoo) sem pouzil primo ovladace v kernellu (tuxonice-2.6.36) ktery nema sice dobrou podporu pro digitalni cast (tu sem tam nerzchodil, ale jinak chodi, to mam zase rozchozeno na ubuntu), ale zato sem tam rozchodil analogovou cast. A pak uz slo nahravat jak z S-video tak z composite (jack, je jenom pro stereo zvuk, cichn je composite a s-vide, pro s-video). Jediny problem je z nekvalitou signalu (behaji mi po tom svetle pruhy, ale jenom hodne jemne), ale hlavne zvuk hodne brumi, a nevim presne cim to je zpusobeho (samotny vystup z UPC nebrumi). Mozna nejaky relikt sitoveho 50Hz.

Oproti tomu co se pise tady na netu sem musel pridat jeste paramter fps=24:framebuffer=64 do mplayer-u (resp. mencoderu), jinak se to seka.
