GStreamer multimedia framework
d6443170cf
Original commit message from CVS: 2004-07-14 Andy Wingo <wingo@pobox.com> * gst/gsttag.c: Add a tag merge func for pointers. The header was there all along, but the function wasn't. (guile-gstreamer's build system uses the address of the function -- I wasn't actually trying to use this.) 2004-07-13 Andy Wingo <wingo@pobox.com> * gst/gstpad.c (gst_pad_try_set_caps): Naive link functions (such as gst_pad_proxy_pad_link) just link to every other pad when they are called. In the case where the graph has cycles, this will mean that a call to try_set_caps will recurse. Allow this recursion and return OK, while we wait for the first try_set_caps to give a proper return value. (gst_pad_link_call_link_functions): Since this function is the only one to set the NEGOTIATING flag on a pad, if the flag is set it means that the link functions have indirectly recursed. If this happens, error out to avoid infinite recursion and an eventual SEGV. (gst_real_pad_class_init): Remove a crufty GtkObject comment. (gst_pad_proxy_getcaps): Intersect the result with the template caps to ensure that the return value is valid. 2004-07-11 Andy Wingo <wingo@pobox.com> * gst/gstdata.c (gst_data_is_writable): s/>=/>/. If there is only one refcount, the calling function is the owner of the buffer. |

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"
