如何将gstreamer videosink嵌入浏览器

Question

我正在开发一个webkit-kernel-browser插件。 大部分插件都遵守NPAPI的规则。 在调用NP_new函数后，浏览器应调用Npp_setwindows等。 但Chrome浏览器不运行此操作。 它调用Np_destory直接完成实例。 所以我无法让浏览器的xid设置它的视频链接。 如何解决？

而当我使用firefox浏览器时，我可以得到xid。 不幸的是，当我使用gst_x_overlay_set_xwindow_id嵌入到浏览器。 浏览器崩溃。 以下是一些测试代码。

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);enter code here 
// 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);

谁能给我关于这些的一些信息？

最好的问候， 森林
