Summary of black screen problems in unity UMP packaging

What I'm using now Unity The version is 2019.4.16f, In the use of UMP There is a black screen problem when playing the surveillance video stream . Summarize the solution to the problem .

Question 1 ：UMP Plug in version issue

At first I used 2.0.2 Version of UMP I found this version in 2019 Of unity There are many problems in , Could have been in Resources->UMPSettings Configure related paths , But this version cannot . So please use 2.0.2 Plug ins above version .

The second question is ：dll File path problem of

This is what you will find , There is no problem playing it on your computer after packaging , But there will still be a black screen problem when sending the bag to colleagues . Because you have to VLC It's an absolute path , You can't find it on others' computers .

1. Uncheck the Use installed VLC

 2. Modify the code UniversalMediaPlayer->Editor->UMPPostBuilds Medium BuildWindowsPlayer64 function .

  public static void BuildWindowsPlayer64(string path, UMPSettings settings)
    {
        string buildPath = Path.GetDirectoryName(path);
        string dataPath = buildPath + "/" + Path.GetFileNameWithoutExtension(path) + "_Data";

        if (!string.IsNullOrEmpty(buildPath))
        {
            if (!settings.UseExternalLibraries)
            {
                CopyPlugins(settings.AssetPath + "/Plugins/Win/x86_64/plugins/", dataPath + "/Plugins/plugins/");
                // Modify the code 
                string[] files = Directory.GetFiles(dataPath + "/Plugins/x86_64/");
                foreach (string str in files)
                {
                    string file = Path.GetFileName(str);
                    Debug.LogError(file);
                    File.Copy(str, dataPath + "/Plugins/" + file);
                }
                Directory.Delete(dataPath + "/Plugins/x86_64/", true);



            }
            else
            {
                if (File.Exists(dataPath + "/Plugins/" + UMPSettings.LIB_VLC_NAME + ".dll"))
                    File.Delete(dataPath + "/Plugins/" + UMPSettings.LIB_VLC_NAME + ".dll");

                if (File.Exists(dataPath + "/Plugins/" + UMPSettings.LIB_VLC_CORE_NAME + ".dll"))
                    File.Delete(dataPath + "/Plugins/" + UMPSettings.LIB_VLC_CORE_NAME + ".dll");
            }
        }
        Debug.Log("Standalone Windows (x86_x64) build is completed: " + path);
    }
