[theora] Add an intro to a theora file without re-encoding?

Hi Michael,

I don't want to bother the theora guys with stuff from the Ogg Video Tools. There is a mailing list hosted with the sourceforge project, that may be more appropriate.

Maybe we could discuss any details and bugs there.   

However ...

I actually have two main categories in the build process: 
The simple tools (oggJoin, oggSplit, oggCut, oggCat) they do not need any additional libraries like theora or vorbis.
And additional tools, that have dependencies to both libraries. (named WANT_OGGSLIDESHOW, as this was the first one)

I should have added a third, that only depends on vorbis, but I was lazy and put oggSilence into the second category.

I use pkg-config to identify if theora is available (so most things are done automatically). Is your path to the package configuration not set correctly?

You may try to set PKG_CONFIG_PATH by hand to the place where theora.pc is placed (something like /usr/lib/pkgconfig/).

PS: I'm just setting up a virtual machine with ubuntu to test the new release 0.8, so I'll gonna test this as well.
