Bug στον mplayer, δεν παίρνει screenshots: Could not open libavcodec PNG encoder

[markelos]

Αντιμετωπίζει κανένας άλλος το ίδιο πρόβλημα; Χρησιμοποιώ σαν frontend τον smplayer. To log του mplayer είναι το εξής

Όπως παρατηρείτε,

Couldn't open video filter 'screenshot'.[/b]

 

παρ' όλο που έχω την τελευταία έκδοση του libavcodec51, δεν παίρνει screenshots. Υπ' όψιν ότι το πρόβλημα δεν υπήρχε στην αρχή που πρωτοέστησα τo debian. Έχει αναφερθεί σαν bug στο forum του smplayer καθώς και στο debian-bugs-dist.

και γω το ιδιο προβλημμα ειχα και μετακομισα σε xine

το mplayer ειναι για εξωτικες κωδικοποιησεις μανουλα

αντιθετα το χινε ειναι ιδανικο για dvd

απο τα δυο πιο ωριμο θεωρω το χινε και τα παμπολα fronted

[markelos]

Έλα όμως που το θέλω για High Definition ταινίες....

Αν αλλαζες την video output παραμετρο σε gl ή gl2, μηπως το κανει?

Μπα τίποτα... Δοκίμασα και άνοιξα μια ταινία με

>mplayer -vf screenshot "movie"

αλλά εξακολουθεί και δε βγάζει screenshot εμφανίζοντας το μήνυμα
