Below are some simple instructions to generate doxygen documentation for Libjingle/WebRTC. It took me a while to figure this out and hopefully this can help someone save some time.
1. Get code from google code
svn checkout http://libjingle.googlecode.com/svn/trunk/ libjingle-read-only
2. Create docs folder and create doxygen file "libjingle.doxy" with the following configurations
INPUT = talk/app talk/base talk/media talk/p2p talk/session talk/sound talk/xmllite talk/xmpp talk/examples
FILE_PATTERNS = *.cc *.h
RECURSIVE = YES
EXCLUDE_PATTERNS = *_unittest.cc
EXTRACT_ALL = YES
SOURCE_BROWSER = YES
INLINE_SOURCES = YES
REFERENCED_BY_RELATION = YES
doxygen docs/libjingle.doxy
Enjoy.
