[MPlayer-users] mplayer ( and transcode ) can't detect sound in a VOB file

[Daniel Kasak]

Hi all.

I have a couple of vob files ( 8 Mile ) taking up a LOT of room on my 
hard disk :)
I'd like to encode them so I can burn the movie onto CD and free some 
space, but mplayer, mencoder and transcode all have problems with the 
audio of the 3rd and 4th VOB file - ie they can't play it at all.

Transcode gives some cryptic error about there being no audio track.

However xine plays all of the VOB files with no issues. When I 
right-click the video window in xine and ask for details of the current 
stream, I'm told the audio is:
Codec: A/52 5.1
Channels: 2
Bitrate: 384000
Bits: 16
Samplerate: 48000

Below is the output of mplayer -v -vo xv -ao alsa9 VTS_01_3.VOB.
Areas of note are:

- audio detected as 'AC3: 2.0 (stereo)  11025 Hz  144.0 kbit/s'
- 'a52: CRC check failed!'   //  'a52: error at resampling' errors 
scattered around the place

Does anyone know what's up, or how I might go about extracting the audio 
into a more mencoder-friendly format so I can encode it?

Thanks!

Dan

Too many video packets in the buffer: (4096 in 8261791 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.
