Nos vegul megvettem a kartyat. A tuner mukodik rendesen, szep a kep, de sajnos nem tudom ravenni, hogy legyen hangja.

Igy probalkoztam mplayer-el:

a kerdes jo, a valasz engem is erdekel. be kell tolteni az saa7134_alsa modult, akkor lesz egy device (pl. nalam oss emulacioval /dev/dsp3) amibol lehet kiolvasni a hangot (pl. bele cat-olod egy fileba, aztan play-jel lejatszod). na most mencoder veszi is, viszont az mplayer-t nem tudtam ravenni, hogy olvassa ki a hangot, aztan kuldje ki a /dev/dsp-n (forceaudio, meg ilyesmiket probaltam). meg meg az is van, hogy a mencoder-rel egyszer sikerult felvenni, aztan rebootig elment a hang (modul ujrabetoltese sem segitett).

- Use the Source Luke ! -

Koszi. Azt hiszem az immediatemode=0 hianyzott. Most igy hasznalom:

mplayer -tv driver=v4l2:device=/dev/video0:adevice=/dev/dsp2:audiorate=32000:forceaudio:immediatemode=0 tv://

viszont ha nem "q"-val hanem ctrl+c-vel lepek ki az mplayerbol, akkor elmegy a hang rebootig...

Hi,

Ezzel a paranccsal mar hallani valamit de masodpercenkent megszakad a kep es a hang egy pillanatra: 


mplayer -tv driver=v4l2:device=/dev/video0:amode=1:alsa:audiorate=32000:forceaudio:immediatemode=0:adevice=hw.1 tv:// -ao alsa

Itt az output:

koszonom a segitseget, sokat haladtam a beuzemelesben. az akadozo kep es hang problemat (video buffer full) a buffersize=32 megoldotta, igy most jonak tunik minden.
Most mar a mencoder-t kostolgatom, szeretnem felvetelre hasznalni a kartyat. egyenlore csuszik a hang es kep, de amint olvasgatom itt a forumtemakat ez mindennapi problema es hamar talalok ra megoldast.

Udv,

ha rá van kötve a hang az aux-ra (szal nem sw-vel nyeri ki a hangot), akkor milyen sebességen megy a csatorna váltás?

van egy Pinnacle PCTV Hybrid Pro PCI kártyám, de a csatornaváltás cefettül lassú, amíg pl egy Leadtek WinFast TV 2000XP esetén nagyon gyorsan váltja a csatornát az mplayer (igaz, a másodiknál minden csatornaváltásnál eléggé "felcsattan" a hang)
