c# - 使用 MediaFoundation 渲染 h264 视频时 SharpDX 崩溃

Question

我在 SharpDX 应用程序中循环播放 h264 视频，有时我会遇到无法找到原因的崩溃。

SharpDX.SharpDXException: HRESULT: [0xC00D36BA], Module: [Unknown], ApiCode: [Unknown/Unknown], Message: Unknown
at SharpDX.Result.CheckError()
at SharpDX.MediaFoundation.MediaFactory.GetService(ComObject unkObjectRef, Guid guidService, Guid riid, IntPtr& vObjectOut)

在这个函数中调用它：

    public static Surface GetSurfaceFromMediaBuffer(MediaBuffer videoBuffer)
    {
        IntPtr surfacePtr;

        MediaFactory.GetService(videoBuffer, mMrBufferService, typeof (Surface).GUID, out surfacePtr);

        return new Surface(surfacePtr);
    }

是否有与 Surface 或 MediaBuffer 相关的东西需要处理？
