Actually, what got me onto this was trying to fix the breakage in the
ogt and cvd subtitles. So add those two the list. The test example I
tried was one mentioned in the past:
The above link is down, and it is unclear whether it will be
reinstated soon. So I've put it temporarily in
I hope someone can copy it to a videolan-centric test area if there is
one. I tried removing the ogt module libsvcdsub_plugin.so but that
didn't help. I get:
Xlib: unexpected async reply (sequence 0xfb7)!
 main decoder error: no suitable decoder module for fourcc `ogt '.
VLC probably does not support this sound or video format.

That's why I started on the ogt and cvd plugins ;-)

Things have been a little chaotic for me. There are a number of things
needing fixing - like how to just build vlc :-) Actually, I can now do
that thanks to your help. So I'll look at when I get a chance.
One of the things I'm working on is another release for libcdio, and
the next release will add CD-Text support, at least on most
OS's. Darwin remains difficult. So probably the libcdio cdda plugin
fixup will be done in conjunction to adding CD-Text support. (It's
there already in the libcdio xine cdda plugin.) Seems a pity to work
on cdda to basically get to the same place as before. May as well add
something new that's been missing.
I'm also waiting for a patch to be accepted to libmusicbrainz so that
it could be used in a cdda plugin. The xine non-libcdio plugin which
has musicbrainz support seems to cut-and paste from the libmusicbrainz
library. Depending on whether my patch or something similar gets in,
musicbrainz support will be added to the libcdio cdda plugin.

Okay thanks for the info. If there is a documentation location for
this kind of useful info (what a developer might need to know about
working with vlc) let me know and I'll add it.

Actually, after removing the old plugins I was getting core dumps when
run from the source tree. Perhaps it's because I didn't do the
"toolbox --distclean". On my 1GHZ athlon box it takes something like
20 minutes to build vlc, so this is not something I enjoy doing.

Yep. I fixed that sometime between my last post and your reply. I've
since remade vlc with wx. And although things are at least more
familiar now, alas I can't say that things by in large work any
better. I mentioned the problems not so much as disparaging remarks so
much as things seem broken and I don't know which of the error
messages are the ones that are relevant.
A small thing I've noticed is that although I can start svlc and wxvlc
okay, if I start wxvlc and then try to switch to the skinned version I
get a core dump. Here is a traceback.

For me this is not critical -- I just won't do the switching.

Okay. Again, since I don't know what's causing my problem I wasn't
sure if this was it or not. Ditto for the reduce_mousever.png, but
thanks for fixing.
