In the SDK, static plugins are built in the following way: * Using GST_PLUGIN_DEFINE2 instead of GST_PLUGINS_DEFINE [1] * Adding the cflag -DGST_PLUGIN_BUILD_STATIC When GST_PLUGIN_BUILD_STATIC is defined, a funtion to register this plugins statically is defined with the name: gst_plugin_foo_register. To check that this function is define properly you can use nm in the following way: arm-linux-androideabi-nm $CERBERO/PREFIX/lib/gstreamer-0.10/static/libgstfoo.a | grep gst_plugin_foo_register Your plugin should be therefore built with -DGST_PLUGIN_BUILD_STATIC and installed to lib/gstreamer-0.10/static/ together with its libtool library. In case you are adding a new plugin to an existent gstreamer project, you will only to need to configure with the options " --enable-static-plugins --enable-static --disable-shared" and make sure your plugins is installed in lib/gstreamer-0.10/static/ instead of lib/gstreamer-0.10/ Cheers, Andoni [1] <a class="moz-txt-link-freetext" href="http://cgit.freedesktop.org/gstreamer-sdk/gst-plugins-base/tree/gst/volume/gstvolume.c#n1046">http://cgit.freedesktop.org/gstreamer-sdk/gst-plugins-base/tree/gst/volume/gstvolume.c#n1046</a> [2] <a class="moz-txt-link-freetext" href="http://cgit.freedesktop.org/gstreamer-sdk/gst-plugins-base/tree/configure.ac#n375">http://cgit.freedesktop.org/gstreamer-sdk/gst-plugins-base/tree/configure.ac#n375</a> [3] <a class="moz-txt-link-freetext" href="http://cgit.freedesktop.org/gstreamer-sdk/gstreamer/tree/gst/gstplugin.h#n341">http://cgit.freedesktop.org/gstreamer-sdk/gstreamer/tree/gst/gstplugin.h#n341</a> </pre> <blockquote type="cite"> <pre wrap=""> ----- Mail original ----- De: <a class="moz-txt-link-abbreviated" href="mailto:stic@free.fr">stic@free.fr</a> À: "Discussions about GStreamer on Android" <a class="moz-txt-link-rfc2396E" href="mailto:gstreamer-android@lists.freedesktop.org"><gstreamer-android@lists.freedesktop.org></a> Envoyé: Mardi 19 Mars 2013 11:19:43 Objet: Re: How to provide a custom plugin to gstreamer in Android ?
