ogg dev - May 2009 - Convert skeleton to "regular" format

Hi there,

we just encountered a problem with some tools obviously encoding into
the skeleton format by default, which leads to problems with several
other tools, in that particular case it's oggCut. When we try to
edit/cut an ogg file with it, the program crashes with a segfault.

I was able to locate and fix the problem in the oggCut source but I am
wondering how to convert my ogg files to a non-skeleton version in general.

Thanks for your help
Oliver

oggz rip -c theora -c vorbis -o file-without-skeleton.ogg file-with-skeleton.ogg

This tool is from liboggz, git.xiph.org. You need a -c option for each stream
type you might have you want to keep (eg, Speex, etc).

Thanks for the quick response. What about multiple theora files? From
what I read it is possible to embed several theora streams in a
skeleton. How to you discern them with that tool?

Thanks

just a quick addition for the mailing list archive: You can achieve that
with the tool "oggz-rip" from the package "oggz-tools" in
Debian and
Ubuntu distros. So the command line becomes:

oggz-rip -c theora -c vorbis -o file-without-skeleton.ogg
file-with-skeleton.ogg

Thanks again for your quick help

Hi Oliver,

I thought I fixed the problem with oggCut and ogg skeleton. What version of the
Ogg Video Tools are you actually using? If you fixed the problem, I would be
happy for a patch :-).

Can you provide me the file that causes the crash for debugging?

Best Regards - Yorn

Well, the fix was more of a hack :) I was using oggvideotools 0.7a and
the fix is removing the output from lines 189-191 in oggCut.cpp. The
toString() method seems to trigger the segfault.
