Hello All,
I am facing error in creation of the appsrc element. The pipeline is like this. appsrc ! encoder ! filesink when am creating the appsrc element as follows src = gst_element_factory_make("appsrc", "testsource") am getting the following error :- (appsrc:21208): GLib-GObject-CRITICAL **: g_object_set: assertion `G_IS_OBJECT (object)' failed ./appsrc: symbol lookup error: /lib/libgstapp-0.10.so.0: undefined symbol: g_once_init_enter_impl Can somebody please tell me what this error is all about ? I am using gst-plugins-bad-0.10.14.tar.gz.

This means that your GLib is too old (and older than the version that libgstapp was compiled against). > I am using gst-plugins-bad-0.10.14.tar.gz. appsrc has been in gst-plugins-base for some time. You should probably use newer versions of things.

You seem to have a broken installation. Likely it is using a too old glib version.

Thanks Wim and Tim.
Now I have installed the new glib, gstreamer and gts-plugin-base versions as follows glib - glib-2.22.4 gstreamer - gstreamer-0.10.26 gst-plugin-base - gst-plugins-base-0.10.26 Still I am getting the error as follows GLib-GObject-CRITICAL **: g_object_set: assertion `G_IS_OBJECT (object)' failed GStreamer-CRITICAL **: gst_bin_add_many: assertion `GST_IS_ELEMENT (element_1)' failed GStreamer-CRITICAL **: gst_element_link_many: assertion `GST_IS_ELEMENT (element_1)' failed symbol lookup error: /lib/libgstapp-0.10.so.0: undefined symbol: g_once_init_enter_impl However when I am creating the pipeline gst-launch appsrc name=testsource ! jpegenc ! fakesink the pipeline states are setting as follows Setting pipeline to PAUSED ... Pipeline is PREROLLING ... The same through the application is giving the errors as mentioned above. Please suggest if I am doing any thing wrong still. And thanks in advance for going through this long mail. For reference, I am attaching the application below __________________________________/* start of application */ int main(int argc, char *argv[]) { /* Initialize Gstreamer */ gst_init(&argc, &argv); /* Declare elements and variables */ GstElement *pipeline = NULL; GstElement *src = NULL ; GstElement *sink = NULL; GstElement *encoder = NULL; char *data = NULL; FILE *fp = NULL; int FileSize = 0; /* Create elements */ pipeline = gst_pipeline_new("testing appsrc"); if(!pipeline){ g_printf("pipeline could not be created\n"); } src = gst_element_factory_make("appsrc", "testsource"); if(!src){ g_printf("source element could not be created\n"); } sink = gst_element_factory_make("filesink", "file sink"); if(!sink){ g_printf("source element could not be created\n"); } encoder = gst_element_factory_make("jpegenc", "jpeg encoder"); if(!encoder){ g_printf("source element could not be created\n"); } /*set properties of the elements */ g_object_set(G_OBJECT(src), "caps", "ANY", NULL); g_object_set(G_OBJECT(sink), "location", "/root/image01.jpg", NULL); /* link the elements */ gst_bin_add_many(GST_BIN(pipeline), src, encoder, sink, NULL); gst_element_link_many(src, encoder, sink, NULL); /* set them to play */ gst_element_set_state(pipeline, GST_STATE_PLAYING); /* create buffer */ data = XXX; /* pass the buffer */ send_buffer_to_application(pipeline, data, FileSize); /* stop the pipeline */ gst_element_set_state(pipeline, GST_STATE_NULL); g_object_unref(pipeline); return 0; } _______________________________/* end of application */ regards, Arnab ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.

I am getting the same problem in my Ubuntu machine.
when I launch the plugin as $gst-launch -v playbin2 uri=file:/home/student/GStreamer/practice/Hello.ogg it is working fine. But when I am trying to run my application I am getting the error: $./prac2 Hello.ogg (prac2:1870): GLib-GObject-CRITICAL **: g_object_set: assertion `G_IS_OBJECT (object)' failed (prac2:1870): GStreamer-CRITICAL **: gst_element_set_state: assertion `GST_IS_ELEMENT (element)' failed I have installed in my Ubuntu machine (Ubuntu 10.04.2 LTS) the following GStreamer plugins : gstreamer0.10-tools 0.10.28.1 gstreamer0.10-alsa 0.10.28.1 gstreame0.10-ffmpeg 0.10.10.1 gstreamer-plugin-base 0.10.28.1 gstreamer-plugin-good 0.10.21 gstreamer-plugin-ugly 0.10.14.1 gstreamer-plugin-ugly-m 0.10.14 gstreamer-plugin-bad 0.10.18 totem 2.30.2 Please suggest .what am doing wrong??? |
Hi,
It seems to me that it comes from the setups of your compilation... Make sure you have edited your PATH correctly in .bashrc : "export GST_PLUGIN_PATH=/usr/local/lib/gstreamer-0.10 export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:usr/local/lib/gstreamer-0.10" What is going on is that the GstElement you need (playbin2) to build the pipeline is in a lib which is located in /usr/local/lib/gstreamer-0.10.... which has to be precised to your computer during the building of your application. You can check that by a gst-inspect-0.10 playbin2...... it show what library is used.... In your case : libgstplaybin.so.... Tell me if that works! |
