If http://www.mars.org/mailman/public/mad-dev/2001-May/000262.html is
to be believed, the last buffer must be followed by a number of 0 bytes
in order for the last frame to be decoded (at least in some cases).
Doing so seems to work here, fixing a missing 1152 samples when using
mp3parse before mad (not using mp3parse would yield the correct amount
of samples, if there's extra non-MP3 data after (eg, tag data)).
ID3 tags are usually handled by id3demux, and should be handled
by id3demux. Tag handling in mad based on libid3tag is very basic
and mostly unnecessary really, so just build this plugin without
ID3 tag support if libid3tag is not available.
Original commit message from CVS:
* ext/mad/gstmad.c: (gst_mad_src_event), (gst_mad_chain),
(gst_mad_change_state):
* ext/mad/gstmad.h:
track discont on incomming buffers and set discont on outgoing
buffers.
Pass unknown events upstreams instead of dropping them.

Cache all events except EOS if we still have to send a NEWSEGMENT
event. This will let TAG events be forwarded until after decodebin
to an encoder for example as decodebin only links the pads
after NEWSEGMENT. Fixes bug #518933.

Add id3demuxbin (which is a simple bin consisting of id3demux
and typefind), take over rank from id3demux, remove typefind
code from id3demux. Makes all broken mp3s that I know of work,
and thereby fixes#152688.

deprecate id3tag element and replace with id3demux/id3mux.
great side effect: this ugly file is now even uglier, yay!

remove non-available function
update for new get_type
Original commit message from CVS:
rework id3tag plugin to work as
a) parser - just strip id3 tags
b) tag reader - extract tags and go EOS
c) tag writer - change id3 tags
Included is some revamping to ease code to make it possible to strip id3tag from its mad dependency (without ID3v2 support), which would still make the parsing bits work. This is however not done yet.
This plugin supercedes the id3types plugin.
Original commit message from CVS:
tagging stuff and build fixes. In detail:
- make gdk-pixbuf loader work when distchecking
- fix invalid syntax in ffmpeg Makefile. wildcards for EXTRA_DIST are not allowed. This broke builds where distdir != srcdir
- fix ffmpeg cvs grabbing when srcdir != distdir
- new id3tag plugin for id3 tag reading/writing (uses mad's libid3tag)
- mad and libid3tag require mad/libid3tag v0.15. Fixed configure to require that
- added ogg demuxer in ext/ogg. The demuxer does not handle events yet. Especially getting seeking right will require some effort or code copying from libvorbis.
- added raw vorbis detection to typefinding. oggdemux requires a typefind function to detect its contents.
- tags plugin in gst/tags. Provides API in <gst/tags/gsttagediting.h>. API includes tag matching GStreamer <=> ID3 and GStreamer <=> vorbis and writing/reading vorbiscomments or ID3v1 tags. Also included is a simple vorbiscomment reader/writer. Writing will not really work though until someone writes oggmux.
- various build fixes. Mostly missing (DIST)CLEANFILES.
- vorbisenc handles tag writing.
Now it's YOUR turn to fix and write more plugins that handle writing/reading of tags. :)
