Question

这有点长，所以请耐心等待。

我上周从Unity资源商店购买了一项资产，ump-pro-android-ios和ump-pro-win-mac-linux-webgl。我遵循将两种资产合二为一的规则。所以这就是事情。我有这个错误

异常：找不到LibVLCAttribute。 UMP.InteropLibraryLoader.GetInteropDelegate [libvlc_media_get_stats]（IntPtr处理程序）（在Assets / UniversalMediaPlayer / Scripts / Sources / InteropLibraryLoader.cs：149） Rethrow as MissingMethodException：函数的地址＆＃39;＆＃39;在1721499648库中不存在。 UMP.InteropLibraryLoader.GetInteropDelegate [libvlc_media_get_stats]（IntPtr处理程序）（在Assets / UniversalMediaPlayer / Scripts / Sources / InteropLibraryLoader.cs：173） UMP.VlcMethods.LoadMethodsFromVLCLibrary（IntPtr处理程序）（在Assets / UniversalMediaPlayer / StreamingWork / VlcMethods.cs：59） Rethrow as ArgumentException：在提供的路径中找不到合适的libvlc：函数的地址＆＃39;＆＃39;在1721499648库中不存在。参数名称：libvlcDirectory UMP.VlcMethods.LoadMethodsFromVLCLibrary（IntPtr处理程序）（在Assets / UniversalMediaPlayer / StreamingWork / VlcMethods.cs：64） UMP.VlcMethods..ctor（）（在Assets / UniversalMediaPlayer / StreamingWork / VlcMethods.cs：41） UMP.VlcMethods.get_Instance（）（在Assets / UniversalMediaPlayer / StreamingWork / VlcMethods.cs：19） DealerLiveCam + c__Iterator0.MoveNext（）（在Assets / UniversalMediaPlayer / StreamingWork / DealerLiveCam.cs：201） UnityEngine.SetupCoroutine.InvokeMoveNext（IEnumerator枚举器，IntPtr returnValueAddress）（在C：/buildslave/unity/build/Runtime/Export/Coroutines.cs：17） UnityEngine.MonoBehaviour：StartCoroutine（IEnumerator的） DealerLiveCam：OnPrepared（Texture2D）（在Assets / UniversalMediaPlayer / StreamingWork / DealerLiveCam.cs：154） UnityEngine.Events.UnityEvent`1：调用（T0） UniversalMediaPlayer：OnPlayerPrepared（Texture2D）（在Assets / UniversalMediaPlayer / Scripts / UniversalMediaPlayer.cs：1151） UMP.PlayerManagerEvents：CallEvent（）（在Assets / UniversalMediaPlayer / Scripts / Sources / Players / Managers / PlayerManagerEvents.cs：147） UMP.c__Iterator0：MoveNext（）（在Assets / UniversalMediaPlayer / Scripts / Sources / Players / Managers / PlayerManagerEvents.cs：118） UnityEngine.SetupCoroutine：InvokeMoveNext（IEnumerator，IntPtr）

这引导我进入资产脚本 InteropLibrary.cs

var attrs = typeof(T).GetCustomAttributes(typeof(InteropFunctionAttribute), false);
            if (attrs.Length == 0)
                throw new Exception("Could not find the LibVLCAttribute.");

当我在 PC 上构建它时，我的流媒体方法正在运行，当我在 Android 上试用它时它没有工作它告诉我 logcat的
