Question

我正在尝试在使用webkitgtk并用C语言编写的程序中播放html5视频。

为了测试html5视频，我设置了一个带有网页的服务器：

<!DOCTYPE html>
<html>
 <head>
</head>
<body>
<video autoplay="autoplay" >
<source src="./movie.ogv" type="video/ogg">
Your browser does not support the video tag.
</video> 
</body>
</html>

并且它在firefox中有效，但是当我使用我的程序显示该网页时，视频无效。

我的C程序：

#include <gtk/gtk.h>
#include <webkit/webkit.h>


static void destroyWindowCb(GtkWidget* widget, GtkWidget* window);
static gboolean closeWebViewCb(WebKitWebView* webView, GtkWidget* window);

int main(int argc, char* argv[])
{
    // Initialize GTK+
    gtk_init(&argc, &argv);

    // Create an 800x600 window that will contain the browser instance
    GtkWidget *main_window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_set_decorated(main_window, false);
    gtk_window_move(main_window,0,0);
    gtk_window_set_default_size(GTK_WINDOW(main_window), 800, 600);

    // Create a browser instance
    WebKitWebView *webView = WEBKIT_WEB_VIEW(webkit_web_view_new());

    // Create a scrollable area, and put the browser instance into it
    GtkWidget *scrolledWindow = gtk_scrolled_window_new(NULL, NULL);
    gtk_scrolled_window_set_policy(GTK_SCROLLED_WINDOW(scrolledWindow),
            GTK_POLICY_AUTOMATIC, GTK_POLICY_AUTOMATIC);
    gtk_container_add(GTK_CONTAINER(scrolledWindow), GTK_WIDGET(webView));

    // Set up callbacks so that if either the main window or the browser instance is
    // closed, the program will exit
    g_signal_connect(main_window, "destroy", G_CALLBACK(destroyWindowCb), NULL);
    g_signal_connect(webView, "close-web-view", G_CALLBACK(closeWebViewCb), main_window);

    // Put the scrollable area into the main window
    gtk_container_add(GTK_CONTAINER(main_window), scrolledWindow);

    // Load a web page into the browser instance
    webkit_web_view_load_uri(webView, "http://localhost/");
    //webkit_web_view_load_uri(webView, "http://www.shastaherps.org/sampleHTML5.html#multimedia");

    // Make sure that when the browser area becomes visible, it will get mouse
    // and keyboard events
    gtk_widget_grab_focus(GTK_WIDGET(webView));

    // Make sure the main window and all its contents are visible
    gtk_widget_show_all(main_window);

    // Run the main GTK+ event loop
    gtk_main();

    return 0;
}


static void destroyWindowCb(GtkWidget* widget, GtkWidget* window)
{
    gtk_main_quit();
}

static gboolean closeWebViewCb(WebKitWebView* webView, GtkWidget* window)
{
    gtk_widget_destroy(window);
    return TRUE;
}

任何消化？

感谢。

P.D我从Ubuntu存储库安装了libwebkitgtk。

来自资源文件的支持：

〜$ sudo apt-get install libgtk-3-dev libwebkitgtk-3.0-dev

〜$ gcc -Wall -o videoplayer main.c pkg-config gtk+-3.0 --cflags --libs pkg-config webkitgtk-3.0 --cflags --libs

示例：

/ *在webkit2gtk-4.0 * /

中不可用

不支持资源文件：

〜$ sudo apt-get install libgtk-3-dev libwebkit2gtk-4.0-dev

〜$ gcc -Wall -o videoplayer main.c pkg-config gtk+-3.0 --cflags --libs pkg-config webkit2gtk-4.0 --cflags --libs
