Original commit message from CVS: 2005-05-06 Andy Wingo <wingo@pobox.com> * gst/gstquery.h * gst/gstquery.c (_gst_query_initialize): Extend GstQuery from GstData, init a memchunk. (standard_definitions): Add a few query types, deprecate a few. (gst_query_get_type): New proc. (_gst_query_copy, _gst_query_free, gst_query_new): GstData implementation. (gst_query_new_application, gst_query_get_structure): New public procs. * docs/design/draft-query.txt: Removed LINKS from the query types, because all the rest can be dispatched to other pads -- seemed ugly to have a query that couldn't be dispatched. internal_links is fine as a pad method. * gst/gstpad.h: Add query2 as a pad method, add the new functions in gstpad.c, but maintain binary compatibility for the moment. Will fix before 0.9 is out. * gst/gstqueryutils.c: * gst/gstqueryutils.h: New files, implement 3 methods for each query type: parse_query, parse_response, and set. Probably need an allocator as well. * gst/gst.h: Add gstquery.h and gstqueryutils.h to the list. * gst/elements/gstfilesink.c (gst_filesink_query2): * gst/base/gstbasesrc.c (gst_basesrc_query2): Replace old query, query_types, and formats methods. * gst/gstpad.c (gst_pad_query2, gst_pad_query2_default) (gst_pad_set_query2_function): New functions. (gst_real_pad_init): Set query2_default as the default query2 function. Basically just dispatches to internally linked pads. Needs review! * gst/gstdata_private.h (_GST_DATA_INIT): Set data->refcount to 1 without using the atomic operations. Only one thread can possibly be accessing the data at this point. Changed so as to avoid gst_atomic operations. |

WHAT IT IS ---------- This is GStreamer, a framework for streaming media. The fundamental design comes from the video pipeline at Oregon Graduate Institute, as well as some ideas from DirectMedia. It's based on plug-ins that will provide the various codec and other functionality. The interface hopefully is generic enough for various companies (ahem, Apple) to release binary codecs for Linux, until such time as they get a clue and release the source. COMPILING FROM SOURCE --------------------- - check output of ./configure --help to see if any options apply to you - run ./configure make to build GStreamer. - if you want to install it (not required), run make install - You should create a registry for things to work. If you ran make install in the previous step, run gst-register as root. If you didn't install, run tools/gst-register as a normal user. - try out a simple test: gst-launch fakesrc num_buffers=5 ! fakesink (If you didn't install GStreamer, again prefix gst-launch with tools/) If it outputs a bunch of messages from fakesrc and fakesink, everything is ok. - After this, you're ready to install gst-plugins, which will provide the functionality you're probably looking for by now, so go on and read that README. COMPILING FROM CVS ------------------ When building from CVS sources, you will need to run autogen.sh to generate the build system files. GStreamer is cutting-edge stuff. To be a CVS developer, you need what used to be considered cutting-edge tools. ATM, most of us have at least these versions : * autoconf 2.52 (NOT 2.52d) * automake 1.5 * libtool 1.4 (NOT Gentoo's genetic failure 1.4.2) * pkg-config 0.8.0 autogen.sh will check for these versions and complain if you don't have them. You can also specify specific versions of automake and autoconf with --with-automake and --with-autoconf Check autogen.sh options by running autogen.sh --help autogen.sh can pass on arguments to configure - you just need to separate them from autogen.sh with -- between the two. prefix has been added to autogen.sh but will be passed on to configure because some build scripts like that. When you have done this once, you can use autoregen.sh to re-autogen with the last passed options as a handy shortcut. Use it. After the autogen.sh stage, you can follow the directions listed in "COMPILING FROM SOURCE"
