 Posted: Thu Jul 08, 2004 2:35 pm Post subject: [Utilizzo]Come posso estrarre una immagine da un avi? [RIS] |
 |
|
Dunque ho un file .avi generato dalla mia macchinetta digitale.
Vorrei estrarre da esso qualche fotogramma e non so cosa usare.
Ho provato ad emergere cinelerra ma l'ebuild non ebuilda bene, kino ma non mi riconosce l'.avi...
Ho provato ad usare aviplay, kplayer e kmplayer in combinazione con ksnapshot.
Ma quando gli dico di recuperarmi l'immagine, in ksnapshot, la regione interessata, in kplayer/kmplayer/avifile diviene tutta blu.
aviplay mi riporta:

berardi@pcberardi berardi $ aviplay foto/dscf0702.avi

Ed ovviamente mi funzionano 'na meraviglia in play-mode
Qualche suggerimento?
Anche un programmino non in portage va bene (tanto c'e' stow...)
Ciao,

Grazie Fedeliallalinea,
fine (works)
Se a qualcun altro interessa: con le safe flag non compila, ho eliminato tutte le opzioni (a parte -march) e messo -O2
