Waylandsink 1.16.2
Locked
 
|
Dear all,
I have embedded multiple waylandsink overlays into GTK grid this way (the eventbox should be responsible for catching mouse clicks as events): for (int i = 0; i < numberOfRows; i++) { for (int j = 0; j < numberOfCols; j++) { if (counter <= numberOfStreams) { eventBox = gtk_event_box_new(); gtk_widget_set_app_paintable(eventBox, TRUE); gtk_widget_set_double_buffered(eventBox, FALSE); gtk_widget_set_can_focus(eventBox, FALSE); gtk_widget_set_hexpand(eventBox, TRUE); gtk_widget_set_vexpand(eventBox, TRUE); streamDataArray->streamDataArray[counter].video_widget = eventBox; g_print("widget: %d: %d\r\n", counter, eventBox); g_signal_connect(streamDataArray->streamDataArray[counter].video_widget, "draw", G_CALLBACK(video_widget_draw_cb), streamDataArray); g_signal_connect(streamDataArray->streamDataArray[counter].video_widget, "button_press_event", G_CALLBACK(hideWindow), streamDataArray); streamBox = gtk_box_new(GTK_ORIENTATION_VERTICAL, 0); gtk_widget_set_can_focus(streamBox, FALSE); gtk_widget_set_hexpand(streamBox, TRUE); gtk_widget_set_vexpand(streamBox, TRUE); gtk_box_pack_start(GTK_BOX(streamBox), GTK_WIDGET(streamDataArray->streamDataArray[counter].video_widget), TRUE, TRUE, 0); gtk_grid_attach(grid, GTK_WIDGET(streamBox), i, j, 1, 1); counter++; Upon click on the overlay I want to maximize single stream and hide all the others via method hideWindow. This code works for 1.14.5 version of Gstreamer, but does not work for 1.16.2. We wanted to have fully native Wayland application. Do you thing this could be a bug? Should I post code which enlights how the waylandsink is tight to GTK? -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Actually, it does not do anything.
I placed brakepoint on the first line of hideWindow method and it does not step in to the method, seems like the mouse click event is not propagated through eventBox. The stream is running within the window, but left mouse button does not do anything. No I realized I experienced the same problem long ago, described here, seems like it was necessary to resolve something more important, but anyway, it is mentioned here: http://gstreamer-devel.966125.n4.nabble.com/Explaining-Gstreamer-plugin-example-td4692177.html#a4692432 -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Anyway, I also tried to embed stream overlay within a simple application
which is supposed to show stream in first line of a gtkGrid and is followed by rows each containing gtkLabel and gtkDatabox aligned horizontally. But when running: gtk_widget_show_all() The application crashes yielding: setting window handle and size (1024 x 110) Gdk-Message: 19:43:29.156: Error 71 (Protocol error) dispatching to Wayland display. When I replace both rows containing label and graph with single gtkButton. I behaves properly. I am enclosing all all source files. graph.h <http://gstreamer-devel.966125.n4.nabble.com/file/t377705/graph.h> styles.css <http://gstreamer-devel.966125.n4.nabble.com/file/t377705/styles.css> gstreamerHandler.c <http://gstreamer-devel.966125.n4.nabble.com/file/t377705/gstreamerHandler.c> main.c <http://gstreamer-devel.966125.n4.nabble.com/file/t377705/main.c> -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

In reply to this post by horai
Just to note, without the stream, the application works correctly showing
labels and graphs in two rows. Adding streams results in a crash, maybe I did something wrong, but when graphs replaced by gtkButton, it works correctly, but why gtkDatabox (graph) makes such a difference to gtkButton. -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
