Original commit message from CVS: 2006-01-30 Andy Wingo <wingo@pobox.com> * ext/theora/gsttheoraenc.h: * ext/theora/theoraenc.c: Same changes as were done to vorbisenc, although theoraenc was timestamping correctly. Added handling of streams that start with nonzero timestamps. * tests/check/Makefile.am: * tests/check/pipelines/theoraenc.c: New file, basically does same tests as vorbisenc. * tests/check/pipelines/vorbisenc.c: I claim these bugs.
