How to locate the xoverlay of gstreamer to an area in some browser.

Hi stefan,

Nice to see your reply!

Cause it is a test code ,so I use the "xvimagesink".
Anyway ,this videosink support this function.

yes ,in this way ,without "gst_x_overlay_set_*" , it works.

My code about the gstreamer is such like below:


-----------------------------------------
gst_init (NULL, NULL);

    player->pipeline = gst_element_factory_make ("playbin2", "playstation");
    LOGMSG("create playbin2");
    player->audio_sink = gst_element_factory_make ("alsasink",
"audio-sink");
    if (NULL == player->audio_sink)
    {
        player->audio_sink = gst_element_factory_make ("autoaudiosink",
"audio-sink");
        g_warning ("Could not create a GST audio_sink. Audio unavailable.");
    }

    player->video_sink = gst_element_factory_make ("xvimagesink",
"video-sink");
    if (NULL == player->video_sink)
    {
        //pvrvideosink is used for some special solution ,but this case
never used
        player->video_sink = gst_element_factory_make
("pvrvideosink","video-sink");

        g_warning ("Could not create a GST video_sink. Video unavailable.");
    }
   g_object_set (player->video_sink, "force-aspect-ratio", TRUE, NULL);
   
    sprintf(buff," \n pipleline:%p\n video:%p\n audio:%p\n uri:%s\n xid:%d",
           
player->pipeline,player->video_sink,player->audio_sink,player->uri,player->xid);
    LOGMSG(buff);
// log shows all the content is ok
    g_object_set (player->pipeline, "video-sink", player->video_sink, NULL);
    g_object_set (player->pipeline, "audio-sink", player->audio_sink, NULL);
    g_object_set (player->pipeline, "uri",player->uri, NULL);

    player->bus = gst_element_get_bus (GST_ELEMENT (player->pipeline));
    gst_bus_add_watch(player->bus,(void *)process_events,player); 

    LOGMSG("start set winid");
/*
chrome can not get the browser xid ,so it display the image in fullscreen
way with the player 's own window. The firefox can not display the image at
all. It crashed here.
*/
    if (player->xid != 0 )
    {
       
gst_x_overlay_prepare_xwindow_id(GST_X_OVERLAY(GST_ELEMENT(player->video_sink)));
       
gst_x_overlay_set_xwindow_id(GST_X_OVERLAY(GST_ELEMENT(player->video_sink)),player->xid);

        gboolean spt = gst_x_overlay_set_render_rectangle
                      
(GST_X_OVERLAY(GST_ELEMENT(player->video_sink)),10,10,480,270);
        if (!spt)
        {
            LOGMSG("not support the rectangle");
        }
       
gst_x_overlay_expose(GST_X_OVERLAY(GST_ELEMENT(player->video_sink)));

    }

    LOGMSG("set xwinid finished");
    gst_element_set_state(player->pipeline,GST_STATE_PLAYING);

    loop = g_main_loop_new (NULL, FALSE);
    LOGMSG("start player loop"); 
    g_main_loop_run (loop);

------------------------------------------
The code is ugly , but just for test. I don't know what went wrong.

Please give me a hand.

Best Regards!
