Original commit message from CVS: 2006-02-25 Alessandro Decina <alessandro@nnva.org> * ext/annodex/Makefile.am: * ext/annodex/gstannodex.c: * ext/annodex/gstcmmldec.c: * ext/annodex/gstcmmlenc.c: * ext/annodex/gstcmmlparser.c: * ext/annodex/gstcmmlparser.h: * ext/annodex/gstcmmlutils.c: * tests/check/elements/cmmldec.c: * tests/check/elements/cmmlenc.c: Fix a memleak in gst_cmml_track_list_add_clip. Handle overflows in clip's start and end times. Add the "encoded" parameter to cmmldec and cmmlenc caps. Do not parse junk at the end of a CMML preamble buffer. Register a libxml error handler to not print stuff on stderr. Check for bad clip start and end times in the testsuites.
