WD tv Live - Audio non sincronizzato (?)

WD Forum Italiano WD TV Riproduttori Multimediali
1

Ciao a tutti,

sono possessore da poche settimane del WD Tv Live (Firmware aggiornato alla 1.15.10), e ho un problema di questo tipo:

Su diversi file video (episodi di telefilm nello specifico) l’audio è in anticipo di diversi secondi rispetto al video :confounded:

Cosa che non capita se per esempio li guardo al pc (VLC)…

per caso è un problema noto e/o è capitato già a qualcuno qualcosa di simile ?

sono file .flv, non dovrebbero esserci problemi, boh… :flushed:

ty per qualsiasi spunto…

Riscontri questo problema solo con file FLV?

Hai provato altri tipi di video?

Intanto grazie per aver risposto (son passati un po’ di giorni ma ero all’estero e, oltre a non avere sempre internet easy, non avevo lo scatolino con me per fare prove…)

Tornando al problema, in realtà non su TUTTI i file flv c’è questa anomalia.

Nell’Hd ho tanta roba (tra film e serie tv);

-Film, a priama vista  fila tutto liscio (flv ma anche altri formati). Non li ho ovviamente provati tutti ma sembrerebbo ok.

-Serie tv, su diversi file c’è questo problema dell’audio che va per conto suo (nello specifico molto in anticipo)

Purtroppo l’unico punto in comune che ho trovato a prima vista è che sono flv (ma non ha senso immagino, dato che altri flv filano lisci).

Se c’è un modo un pelo piu’ approfondito per analizzare questi file e vedere se hanno qualche caratteristica in comune identificabile…(c’è sicuro, ma io sono un po’ “basico” e oltre a quello che leggo sul video non sono andato :manembarrassed:)

grz!

Ty!  Scaricato e fatto un po’ di prove…
Provo a copiare sotto le info per 4 files, due sono sincornizzati ok mentre per due sul TV live l’audio va nettamente in anticipo… (a prima vista non trovo grosse differenze :flushed:)

Sry se è  lungo ma non so cosa “ripulire”…
