Original commit message from CVS:
Add some sanity tests to gstpad.c. Check that pad is linked before
calling gst_pad_try_set_caps() on it in spideridentity.

* gst/autoplug/gstsearchfuncs.c: (gst_autoplug_caps_intersect):
* gst/autoplug/gstspideridentity.c: (gst_spider_identity_link),
(gst_spider_identity_getcaps), (gst_spider_identity_change_state),
(gst_spider_identity_sink_loop_type_finding):
* gst/autoplug/gstspideridentity.h:
Fix autoplugging in spider element, so it works with new caps.
This was mainly caused by identifying empty caps incorrectly.
Original commit message from CVS:
merge TYPEFIND branch. Major changes:
- totally reworked type(find) system
- bytestream is out of the core again
- typefind element is now part of gstelements
Original commit message from CVS:
s/GstBuffer/GstData/ in the API where you can pass events. Fix the plugins to deal with that. Fixes#113488. Also includes scheduler patches, and probably fixes some queue bugs relating to events and buffers.
Original commit message from CVS:
New typefind system:
* bytestream is now part of the core
* all plugins have been modified to use this new typefind system
* asf typefinding added
* mpeg video stream typefiding removed because it's broken
* duplicate typefind entries removed
* extra id3 typefinding added, because we've seen 4 types of files
(riff/wav, flac, vorbis, mp3) with id3 headers and each of these needs
to work. Instead, I've added an id3 element and let it redo typefiding
after the id3 header. this needs a hack because spider only typefinds
once. We can remove this hack once spider supports multiple typefinds.
* with all this, mp3 typefinding is semi-rewritten
* id3 typefinding in flac/vorbis is removed, it's no longer needed
* fixed spider and gst-typefind to use this, too.
* Other general cleanups
Original commit message from CVS:
implement translatable error messages using gerror.
Includes bugfixes for:
- crash when unlinking Ghostpads
- make *_PAD_* macros use glib casts
- make spider typefinding merge buffers correctly
Original commit message from CVS:
GST_DEBUG reorganization
This is a big diff (ca 450k), containing loads of stuff:
- gstinfo.[ch] complete rewrite
- changing of all GST_DEBUG messages to reflect that change
- reorganization of subsystem disabling
- addition of gstconfig.h.in so we can track the disablings
- <gst/gst.h> does not include <unistd.h> and <config.h> anymore
- documentation updated for gstinfo stuff (build the docs yourself to know what changed)
- bugfixes for making of the docs (files from CVS are not deleted anymore
- testsuite for debugging changes in testsuite/debug
expect breakage
Original commit message from CVS:
some minor improvements:
- better debugging output
- don't set state to paused when plugging anymore
- bugfix: set typefind caps on srcpad, not sinkpad
- remove unnecessary check for right caps
Original commit message from CVS:
general fixes:
- changed newly added locked_state API to work like GStreamer does
- added gst_element_sync_state_with_parent function
- revert: pad linking does not require non-playing state
- updated spider and pipeline parsing to link elements in playing state
- bugfix: pads are now activated when added to a playing element (broke above change)
Original commit message from CVS:
- Use the eventhandler instead of the event function to send events.
- make the scheduler setup the eventhandlers
- intercept flush events on pads links that can potentially queue data
and flush it.
- some more debugging info in spider.
I can think of one case where this flush might fail: unconnected pads where
the scheduler has not set up the eventhandler yet. I'll come up with a
solution for that soon.
Original commit message from CVS:
first phase of spider cleanup
- get rid of the buffer cache for type finding
- do type finding within spider identity instead of in seperate element
- currently doing type finding with the first buffer only. will eventually merge buffer until there is "enough" data to typefind with
- spider now only has 1 sink instead of many. I don't believe it would be possible to mux with spider anyway
- if type finding fails, gst_element_error is called. Its up to the app to catch the error signal and stop the pipeline
Original commit message from CVS:
Add an event function so that seek events are not forwarded when we
have a cache, seeking in the cache still needs to be implemented though..
Original commit message from CVS:
a couple of fixes here:
- forward eos events to all src pads, even if spider didn't connect them. this ensures that the pipeline will stay in a consistant state even when not all pads are sent data
- don't check for nonnull spider until it is actually needed. it really is null when it has been disposed and this method is called.
Original commit message from CVS:
commit to make gstreamer follow the gtk function/macro naming conventions:
GstPadTemplate <-> gst_pad_template <-> GST_PAD_TEMPLATE
and the same for *factory and typefind.
Original commit message from CVS:
* warning fixes
* gst_object_set_name (name, NULL) uniquifies the name globally
- needs robusticizing
* gst_elementfactory_make can now take NULL as a second argument
Original commit message from CVS:
major rewrite of the spider.
Now uses GstSpiderConnection to track current connections and remember the way they're plugged.
Advantages of this approach:
- function prototypes are now much cleaner.
- Allow event propagation (EOS) to elements that are not connected but plugged.
- Allow deconstruction of plugged pipes. (not implemented)
Disadvantage:
- I screwed up naming (always get src and sink the wrong way). It's very inconsistent in the gstspider.[ch] files
- a little more time and memory are needed to manage the structs
Original commit message from CVS:
- use autoplugging instead of predefined way on sometimes pads
- exchange plugtype with factories in the spider
- revamp the spider, now messier than before...
- bugfixing
- style corrections
