GStreamer-sharp无法创建管道 [英] GStreamer-sharp failed to create pipeline

问题描述

我尝试在WPF应用程序中使用Gstreamer显示RTSP流.

I try to display RTSP stream using Gstreamer in my WPF application.

所以我到目前为止:

• 将GStreamer安装到Lo文件夹F:/gstreamer
• 创建了新的WPF应用程序
• 添加了glib-sharp和gstreamer-sharp作为依赖项.

以下我用来初始化库的代码:

The code below I use to init the library:

Gst.Application.Init(); // (1)

mainLoop = new GLib.MainLoop();
mainGLibThread = new System.Threading.Thread(mainLoop.Run);
mainGLibThread.Start();

Element uriDecodeBin = ElementFactory.Make("playbin", "uriDecodeBin0"); // (2)

无法加载DLL'libgstreamer-1.0-0.dll':找不到指定的模块.

Unable to load DLL 'libgstreamer-1.0-0.dll': The specified module could not be found.

在行(1)上

.如果我将所有gstreamer dll复制到bin/Debug文件夹中，则该异常消失了，但第(2)行中的ElementFactory.Make总是返回null，而没有任何异常.如果我尝试做类似

on line (1). If I copy all the gstreamer dlls into bin/Debug folder the exception gone but ElementFactory.Make in line (2) always returns null without any exception. If I try to do something like

Parse.Launch(@"videotestsrc ! videoconvert ! autovideosink")

要测试库功能，我会收到错误消息:

to test the library functionality I get error:

没有元素"videotestsrc"

no element "videotestsrc"

但是如果我从命令行运行它:

but if I run it from command line:

gst-launch-1.0 videotestsrc！视频转换！自动视频接收器

gst-launch-1.0 videotestsrc ! videoconvert ! autovideosink

可以正常工作.

所以我的问题-如何使GStreamer锐化工作?

So my question - how to get GStreamer-sharp work?

推荐答案

将路径更改为GStream并在开始之前添加此代码

Change path to GStream and add this code before start

        string path = @"G:\gstreamer\1.0\x86\"; // path to your gstream
        string pluginpath = @"G:\gstreamer\1.0\x86\lib\gstreamer-1.0\"; // path to your gstream
        string registry = System.IO.Path.Combine(path, "registry.bin");

        Environment.SetEnvironmentVariable("PATH", Environment.GetEnvironmentVariable("PATH") + ";" + path);
        Environment.SetEnvironmentVariable("GST_PLUGIN_PATH", pluginpath + ";" + Environment.GetEnvironmentVariable("GST_PLUGIN_PATH"));
        Environment.SetEnvironmentVariable("GST_PLUGIN_SYSTEM_PATH_1_0", pluginpath + ";" + Environment.GetEnvironmentVariable("GST_PLUGIN_SYSTEM_PATH_1_0"));
        Environment.SetEnvironmentVariable("GST_PLUGIN_SYSTEM_PATH", pluginpath + ";" + Environment.GetEnvironmentVariable("GST_PLUGIN_SYSTEM_PATH"));
        Environment.SetEnvironmentVariable("GST_DEBUG", "*:4");
        Environment.SetEnvironmentVariable("GST_DEBUG_FILE", System.IO.Path.Combine(path, "gstreamer.log"));
        Environment.SetEnvironmentVariable("GST_REGISTRY", registry);
