Strano problema mplayer e vob/ac3
Ciao a tutti,
dopo l'ultimo aggiornamento di mplayer che io ho fatto oggi
(1:1.0.rc2svn20080417-0.0) mplayer non legge più un file vob.
Purtroppo questo è l'unico file vob che ho. Fino a ieri sono sicuro che
funzionava. E' uno spezzone di un film.
Lanciando
# mplayer file.vob
mplayer esce ma non ottengo messaggi di errore (sotto l'intero output).
Se lancio
# mplayer file.vob -nosound
funziona correttamente (solo video).
La cosa strana è che ffplay funziona correttamente (audio+video).
Quindi sembrerebbe un problema di mplayer che non legge l'audio in ac3.
Però se estraggo l'audio dal file con:
# ffmpeg -i file.vob -y -ab 384k audio.ac3
mplayer lo legge correttamente. Il file è:
audio.ac3: ATSC A/52 aka AC-3 aka Dolby Digital stream, 48 kHz,,
complete main (CM) 3 front/2 rear, LFE on,, 384 kbit/s reserved Dolby
Surround mode
Cosa può essere successo?

- MPlayer crashed by bad usage of CPU/FPU/RAM.
Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
disassembly. Details in
DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
gcc version. If you think it's MPlayer's fault, please read
DOCS/HTML/en/bugreports.html and follow the instructions there. We
can't and
won't help unless you provide this information when reporting a
possible bug.
