[MPlayer-users] DVD plays (and rips) without audio :-(

Mon Apr 15 02:16:02 CEST 2002

[sorry if this shows up in duplicate; I've got an error in my first
attempt to post, apparently because I mentioned that I had tried with
a forbidden version of the compiler in addition to one of the approved
ones :-), but I don't see the message in the archives, so I'm trying
again]

[please cc: me on replies; I'm not subscribed (yet? :-)]

Some of my DVDs play perfectly well, but some (e.g., Matrix) come out
without audio.  Even if I try to convert them to AVI first, it doesn't
work.

The problem appears to be correlated with the presence of an initial
copyright notice in the movie video stream, without associated audio
(as opposed to a copyright notice in the introductory video stream
displayed before the main menu).  When playing such VOBs, MPlayer
appears to fail to notice an audio track is introduced after 30
seconds of video or so.  The problem occurs both in mplayer and in
mencoder.

I've tried -ni, -aid {128,129,130}, and some other suggestions in the
on-line docs and in the mailing list, but nothing helped.

I was having this problem with the CVS snapshot of 2002-03-15, but
I've just upgraded today's snapshot without luck.  Built on Red Hat
Linux 7.2 using gcc3-3.0.4-1.

Here are details on what I get in my attempts to convert one of the
already-decrypted VOBs to AVI.  Note that only a small portion of the
VOB ends up being converted.

% mencoder -v -ni -oac copy -ovc copy -o rp1.avi video_ts/vts_01_1.vob

Suggestions on where to look at to try to nail down the bug?  I'm
totally unfamiliar with encoding formats and with MPlayer code :-(

BTW, I'd been able to use -sb in the previous snapshot of mencoder
that I used, to overcome this problem (just to get it again a couple
of megabytes down the road :-), but now mencoder rejects the -sb
option.  Same command line as above, except for `-sb 18000000' added
in the beginning of the argument list:

Error: 'sb' is not an mplayer option
command line: -sb
Exiting... (error parsing cmdline)

With judicious use of -sb and -endpos, it was possible to encode an
entire DVD, with a number of passes, but now, without -sb in mencoder,
it has become pretty much impossible.  Was this change intentional?

Another problem is that I've been unable to rip DVDs with subtitles.
Even though they show up well within mplayer, mencoder seems to be
ignoring the options -sid and -ifo.  It doesn't complain about them,
but the subtitles that show up with mplayer don't make it to the
resulting AVI file, or at least I wasn't able to figure out how to get
them displayed after the movie is converted to AVI.  I've tried using
-vobsub too after creating the AVI without success :-(

Can anyone suggest a procedure for ripping DVDs preserving subtitles
in some selected language that is known to work?

Thanks in advance,
