应用错误收集

我正在实施应该播放视频的应用程序（某种视频播放器）。我使用MediaFoundation进行视频播放，它适用于大多数视频，但未能通过某些视频。

我创建了以下MF拓扑：MF_TOPOLOGY_SOURCESTREAM_NODE - ＆gt; MF_TOPOLOGY_TRANSFORM_NODE（Microsoft H264视频解码器MFT） - ＆gt; MF_TOPOLOGY_TRANSFORM_NODE（Resizer MFT） - ＆gt; MF_TOPOLOGY_TRANSFORM_NODE（Color Converter MFT） - ＆gt; MF_TOPOLOGY_OUTPUT_NODE（SampleGrabberSink）。

当我在我的应用程序中播放某些视频时，会发生以下情况（通过mftrace工具从MF跟踪中获取）：

MF为Resizer MFT创建变换节点，MFTransform和MEdiaObject：

COle32ExportDetours :: CoCreateInstance @ Created {1EA1EA14-48F4-4054-AD1A-E8AEE10AC805} Resizer DMO（C：\ Windows \ SysWOW64 \ vidreszr.dll）@ 0561F060 - 跟踪接口：IMFTransform @ 0561F060，IMediaObject @ 0561F078
MF设置缩放器变换的输入类型和输出类型：

CMFTransformDetours :: SetInputType @ 0561F060成功MT： MF_MT_MAJOR_TYPE = MEDIATYPE_Video; MF_MT_SUBTYPE = MFVideoFormat_YV12; MF_MT_FRAME_SIZE = 3092376453526（720,406）; MF_MT_FRAME_RATE = 107374182401（25,1）; MF_MT_PIXEL_ASPECT_RATIO = 1743756722581（406405）; MF_MT_INTERLACE_MODE = 7; MF_MT_AVG_BITRATE = 639540; MF_MT_DEFAULT_STRIDE = 720; MF_MT_ALL_SAMPLES_INDEPENDENT = 1; MF_MT_FIXED_SIZE_SAMPLES = 1; MF_MT_SAMPLE_SIZE = 438480

用户开始播放视频。
MF再次设置缩放器变换的输入类型和输出类型：

调整器转换器的MediaObject无法处理输出：

在第二次设置输入和输出类型后，ResizerMFT无法处理输出的原因是什么？它是关于输出类型属性的东西吗？有没有办法获得有关此失败的更多信息？

任何答案都将不胜感激。
