Plugin source boilerplate not registering correctly
 
|
Hi, Looking for guidance here... I played with the gst-element-maker to generate a single element. It seems to work fine and gst-inspect detect it fine. However, when I try to replicate decklink and aja plugins where 2 sub plugins needs to get loaded it fails with this error when running gst inspect-1.0:
Failed to load plugin '/usr/local/lib/gstreamer-1.0/libgstadv.so': /usr/local/lib/gstreamer-1.0/libgstadv.so: undefined symbol: gst_audio_src_get_type At this point I'm just trying to load an empty audio source. It is likely something stupid... What I'm missing? I have placed the code here for convenience if somebody can highlight what's wrong. https://github.com/FredT2020/gsPlay FredT _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

You need to link against libgstaudio-1.0, so add gstreamer-audio-1.0 to your pkg-config / dependencies list. (You didn't post your build files, so can only give generic guidance here, details will depend on the build system used of course).

Thanks for the pointer. I switched to meson since it seems more appealing to me. Once i added the dependency I get a different error. It is not seeing the element. Here's the skeleton with meson https://github.com/FredT2020/gstadv (gst-inspect-1.0:12378): GLib-GObject-WARNING **: 09:10:56.321: specified class size for type 'GstAdvAudioSrc' is smaller than the parent type's 'GstAudioSrc' class size (gst-inspect-1.0:12378): GLib-CRITICAL **: 09:10:56.322: g_once_init_leave: assertion 'result != 0' failed (gst-inspect-1.0:12378): GStreamer-CRITICAL **: 09:10:56.322: gst_element_register: assertion 'g_type_is_a (type, GST_TYPE_ELEMENT)' failed Plugin Details: Name adv Description FIXME Template plugin Filename /usr/local/lib/gstreamer-1.0/libgstadv.so Version 0.0.FIXME License LGPL Source module gst-project-plugin Binary package GStreamer Origin URL http://gstreamer.net/ 0 features: On Fri, Jan 10, 2020 at 1:56 AM Tim Müller <[hidden email]> wrote: On Thu, 2020-01-09 at 17:33 -0800, Frederic Turmel wrote: _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
