Will send message to -devel list later with details on the changes and what they mean for Makefile.am writers. Check docs/random/omega/build/TODO for a list of things that I had to make sure of. NOTE: this requires a complete rebuild of all plugins, since I also changed the STATE enum to a bitfield instead of sequential numbers.

Original commit message from CVS: Header cleanup: try to include as little as possible; this will probably speed up compilation a bit. changed the .c files to use #include "..." Fix for the 'plugins are loaded twice' bug. Fix 22186: GstObject flags are now used everywhere. Added *_FLAG_LAST so elements do not use the same flags. Added some padding in the flag enum for future expansion.

Original commit message from CVS: Snapshot of work-in-progress do deal with out-of-bin elements. Current system is very likely going to be ditched due to its complexity and the fact that it doesn't work right now. More than that, it's generating some really odd results in my test program, which aren't readily explainable. If you want to keep a working copy of your working copy (heh), don't update until this is replaced with a hybrid approach. This approach will be the beginning of a plan generator that can construct full hybrid schedules given hints from various places. Hybrid means that cothreads are used, but there are chunks of the pipeline that are actually dealt with by chaining. This can improve speed by reducing cothread switches (which are much cheaper than thread switches, but still far from free, about 570 cycles on my PIII), but does carry a complexity burden. Luckily, the structure of GStreamer allows that burden to live entirely in create_plan. Luck? I think not ;-)

WARNING: Don't grab this updated unless you're really, REALLY sure. Original commit message from CVS: WARNING: Don't grab this updated unless you're really, REALLY sure. WARNING: Wait for the next one. Whole lotta changes here, including a few random bits: examples/*/Makefile: updated to use `libtool gcc`, not just `gcc` gst/ gstbuffer.h: updated to new flag style gst.c, gstdebug.h: added new debugging for function ptrs gstpipeline.c: set type of parent_class to the class, not the object gstthread.c: ditto plugins/ cdparanoia/cdparanoia.c: added an argument type, updated some defaults cobin/spindentity.c: updated to new do/while loopfunction style mp3encode/lame/gstlame.c: argument types, whole lotta lame options tests/: various changes Now, for the big changes: Once again, the scheduling system has changed. And once again, it broke a whole bunch of things. The gist of the change is that there is now a function pointer for gst_pad_push and gst_pad_pull, instead of a hard-wired function. Well, currently they are functions, but that's for debugging purposes only, they just call the function pointer after spewing lots of DEBUG(). This changed the GstPad structure a bit, and the GstPad API as well. Where elements used to provide chain() and pull() functions, they provide chain() and get() functions. gst_pad_set_pull[region]_function has been changed to get_pad_set_get[region]_function. This means all the elements out there that used to have pull functions need to be updated. The calls to that function have been changed in the normal elements, but the names of the functions passed is still _pull[region](), which is an aesthetic issue more than anything. As for what doesn't work yet, just about anything dealing with Connections is hosed, meaning threaded stuff won't work. This will be fixed about 12 hours from now, after I've slept, etc. The simplefake.c test works in both cothreaded and chained cases, but not much else will work due to the Connection problem. Needless to say, don't grab this unless you *need* these features *now*, else wait to update this stuff until tomorrow. I'm going to sleep now.

Original commit message from CVS: Changed the way things are scheduled, especially sources. A Src used to have a push() function, and optionally a pushregion() to deal with async reads, etc. That whole thing has gone away, in favor of providing a pull() function for the output (Src) pad instead, ala chain functions. This makes constructing cothreaded schedules out of non-loop elements somewhat easier. Basically there was always a question as to which pad was being dealt with. In the pullregion case, cothread-specific data was used to try to pass the region struct to the right place, which is a slow hack. And in general, the push function severely limited the kind of tricks that could be played when there's more than one output pad, such as a multi-out file reader with async capabilities on each pad independently. This changes the way cothread scheduling occurs. Instead of the hack to deal with Src's by calling their push() function (or optionally the pushregion(), in certain cases), we now are working towards a general mechanism where pads are the only thing that are dealt with directly. An optimization was made in the process of doing this: the loopfunction actually run as the outer [stack] frame of the cothread is now set more intelligently in create_plan() based on what kind of element it is. We now have: loopfunc_wrapper: used for loop-based elements, it simply calls the loopfunc in a loop, paying attention to COTHREAD_STOPPING (see below). It currently does other, soon to be depracated, stuff. pullsrc_wrapper: wraps a Src that's not loop-based (since your options are now loop- or pull-based) There will be a couple more to deal with other cases, such as Connections and chain-based elements. The general idea is that it's a lot more efficient to make the decisions once in create_plan than to keep doing this huge if/else chain in the wrapper. Just choose the right wrapper up front. It'll be most apparent performance-wise in the case of whichever element context is switched to first for each iteration, since the whole wrapper setup is done for every iteration. The tricky part is that there is now a bit of overloading of the function pointers in a pad. The current meanings (possibly to change a bit more soon) are: chainfunc: as always, chainfunc pointer is mirrored between peer pads (this may change, and the chain func may end up in pushfunc) pushfunc: SrcPad: gst_pad_pushfunc_proxy, cothread_switch to peer SinkPad: none (may take over chainfunc, see below) pullfunc: SrcPad: Src or Connection's function to construct buffers SinkPad: gst_pad_pullfunc_proxy, cothread_switch to peer There are a number of issues remaining with the scheduling, not the least of which is the fact that Connections are still dealt with the old way, with _push() functions and such. I'm trying to figure out a way to unify the system so it makes sense. Following the scheduling system is hard enough, trying to change it is murder. Another useful scheduling addition, mentioned above, is COTHREAD_STOPPING. It's an element flag that's used to signal whatever code is running in cothread context that it should be finishing up and exiting soon. An example of this is in plugins/cobin/spindentity.c. All the loops should now be composed of do/while loops, rather than while(1) loops: do { buf = gst_pad_pull(spindentity->sinkpad); gst_pad_push(spindentity->srcpad,buf); } while (!GST_ELEMENT_IS_COTHREAD_STOPPING(element)); The reason for this is that COTHREAD_STOPPING may be set before the above loop ever gets started. It wouldn't do for the body of the loop to never once get called, that would simply stall the pipeline. Note that only the core library code is ever responsible for setting and unsetting this flag. All elements have to do is respond to it by cleanly exiting the loop and the function holding it. This is needed primarily to allow iterations to occur properly. Basically, there's a single entry point in the cothread scheduling loop, gst_bin_iterate_func() simply switches to this cothread. If the element in this context is allowed to loop infinitely, nothing would even switch back to the context from which the iterate() was originally called. This is a bit of a problem. The solution is for there to be an implicit switch back to the originating context. Now, even I'm not sure exactly how this works, but if the cothread that's switched to actually returns, execution returns back to the calling context, i.e. iterate_func(). COTHREAD_STOPPING is therefore set just before switching into this (currently randomly chosen) context, on the assumption that it will return promptly after finishing its duties. The burden of clearing the flag falls to the various wrapper functions provided by the Bin code, thus element writers don't have to worry about doing that at all (and simply shouldn't). Related changes: All the sources in elements/ have been changed to reflect the new system. FIXMEs: 1) gstpipeline.c calls gst_src_push at some point, dunno why, it's commented out now. 2) any other sources, including vcdsrc, dvdsrc, and v4lsrc will break badly and need to be modified to work as pull-based sources.

This is a megapatch with the following changes: Original commit message from CVS: This is a megapatch with the following changes: - moved the gchar *name to GstObject, removed the ones in GstElement and GstPad. - moved the parent handling completely into GstObject. This cause *all* of the plugins to fail (except those that used gst_pad_get_parent) - rearanged the XML save handling. - GstObject now has a class function save/restore_thyself. - GstObject has a generic method gst_object_save_thyself, this makes it possible to fire a signal wehever a new object is loaded. This is needed so we can add XML save hooks. - GstXML API has changed slightly. You now have to create a GstXML object first before you can actually load something. This makes it possible to attach a signal to GstXML whenever an object is loaded. I'm not sure we will keep this interface. - GstObject can now print the path_string without knowing about the GstPad and GstElement types. - Added gst_bin_get_by_name_recurse_up to lookup an element in the current element hierarchy. - added XML namespaces to the saved pipelines the namespace is: http://gstreamer.net/gst-core/1.0/ namespaces are needed to distinguish user generated XML from the core XML. Note that the plugins still contain a macro GST_OBJECT_PARENT that will be replaced with gst_pad_get_parent shortly.

Changed the GstPadFactory and added the GstPadTemplate. Original commit message from CVS: Changed the GstPadFactory and added the GstPadTemplate. The GstPadFactory is an easy way to define a pad with capabilities. The GstPadFactory is converted into a GstPadTemplate. The template is used to create new pads and to expose the possible pads used in an element to the plugin system. updated mp3parse, mpg123, cdparanoia to the new API. Rerun gstreamer-register because the XML definition has changed.

The objects are in place, I now need to go and get all the Bin end of things worked out. Testing should be fairly easy, at least for verification. Everything I've tried so far works with no changes, with is amazing. That's just cool. Once again we rewrite an entire subsystem, and nothing else notices anything but the new features ;-)

This is a megapatch with the following changes: Original commit message from CVS: This is a megapatch with the following changes: - moved the gchar *name to GstObject, removed the ones in GstElement and GstPad. - moved the parent handling completely into GstObject. This cause *all* of the plugins to fail (except those that used gst_pad_get_parent) - rearanged the XML save handling. - GstObject now has a class function save/restore_thyself. - GstObject has a generic method gst_object_save_thyself, this makes it possible to fire a signal wehever a new object is loaded. This is needed so we can add XML save hooks. - GstXML API has changed slightly. You now have to create a GstXML object first before you can actually load something. This makes it possible to attach a signal to GstXML whenever an object is loaded. I'm not sure we will keep this interface. - GstObject can now print the path_string without knowing about the GstPad and GstElement types. - Added gst_bin_get_by_name_recurse_up to lookup an element in the current element hierarchy. - added XML namespaces to the saved pipelines the namespace is: http://gstreamer.net/gst-core/1.0/ namespaces are needed to distinguish user generated XML from the core XML. Note that the plugins still contain a macro GST_OBJECT_PARENT that will be replaced with gst_pad_get_parent shortly.

And once again, it broke a whole bunch of things. The gist of the change is that there is now a function pointer for gst_pad_push and gst_pad_pull, instead of a hard-wired function. Well, currently they are functions, but that's for debugging purposes only, they just call the function pointer after spewing lots of DEBUG(). This changed the GstPad structure a bit, and the GstPad API as well. Where elements used to provide chain() and pull() functions, they provide chain() and get() functions. gst_pad_set_pull[region]_function has been changed to get_pad_set_get[region]_function. This means all the elements out there that used to have pull functions need to be updated. The calls to that function have been changed in the normal elements, but the names of the functions passed is still _pull[region](), which is an aesthetic issue more than anything. As for what doesn't work yet, just about anything dealing with Connections is hosed, meaning threaded stuff won't work. This will be fixed about 12 hours from now, after I've slept, etc. The simplefake.c test works in both cothreaded and chained cases, but not much else will work due to the Connection problem. Needless to say, don't grab this unless you *need* these features *now*, else wait to update this stuff until tomorrow. I'm going to sleep now.

If such an element is found in the pipeline, seeking is disabled for the complete stream (avidecoder cannot deal with seeking until we convert it to a loop based element with pull_region to fetch the indeces etc...)

Region is now specified by a type (OFFSET_LEN, TIME_LEN, etc.) and two guint64's. They are offset and len, where offset can be used for the time field, and len would be zero or the time unit (say, 33ms for video).

WARNING: Don't grab this updated unless you're really, REALLY sure. Original commit message from CVS: WARNING: Don't grab this updated unless you're really, REALLY sure. WARNING: Wait for the next one. Whole lotta changes here, including a few random bits: examples/*/Makefile: updated to use `libtool gcc`, not just `gcc` gst/ gstbuffer.h: updated to new flag style gst.c, gstdebug.h: added new debugging for function ptrs gstpipeline.c: set type of parent_class to the class, not the object gstthread.c: ditto plugins/ cdparanoia/cdparanoia.c: added an argument type, updated some defaults cobin/spindentity.c: updated to new do/while loopfunction style mp3encode/lame/gstlame.c: argument types, whole lotta lame options tests/: various changes Now, for the big changes: Once again, the scheduling system has changed. And once again, it broke a whole bunch of things. The gist of the change is that there is now a function pointer for gst_pad_push and gst_pad_pull, instead of a hard-wired function. Well, currently they are functions, but that's for debugging purposes only, they just call the function pointer after spewing lots of DEBUG(). This changed the GstPad structure a bit, and the GstPad API as well. Where elements used to provide chain() and pull() functions, they provide chain() and get() functions. gst_pad_set_pull[region]_function has been changed to get_pad_set_get[region]_function. This means all the elements out there that used to have pull functions need to be updated. The calls to that function have been changed in the normal elements, but the names of the functions passed is still _pull[region](), which is an aesthetic issue more than anything. As for what doesn't work yet, just about anything dealing with Connections is hosed, meaning threaded stuff won't work. This will be fixed about 12 hours from now, after I've slept, etc. The simplefake.c test works in both cothreaded and chained cases, but not much else will work due to the Connection problem. Needless to say, don't grab this unless you *need* these features *now*, else wait to update this stuff until tomorrow. I'm going to sleep now.

This cause *all* of the plugins to fail (except those that used gst_pad_get_parent) - rearanged the XML save handling. - GstObject now has a class function save/restore_thyself. - GstObject has a generic method gst_object_save_thyself, this makes it possible to fire a signal wehever a new object is loaded. This is needed so we can add XML save hooks. - GstXML API has changed slightly. You now have to create a GstXML object first before you can actually load something. This makes it possible to attach a signal to GstXML whenever an object is loaded. I'm not sure we will keep this interface. - GstObject can now print the path_string without knowing about the GstPad and GstElement types. - Added gst_bin_get_by_name_recurse_up to lookup an element in the current element hierarchy. - added XML namespaces to the saved pipelines the namespace is: http://gstreamer.net/gst-core/1.0/ namespaces are needed to distinguish user generated XML from the core XML. Note that the plugins still contain a macro GST_OBJECT_PARENT that will be replaced with gst_pad_get_parent shortly.
