非标准分辨率下MFCreateSinkWriterFromURL调用失败，MFCreateMPEG4MediaSink正常

创建IMFSinkWriter有两种实现方式：

一、使用MFCreateMPEG4MediaSink #

winrt::com_ptr<IMFByteStream> outputStream;
winrt::check_hresult(MFCreateFile(MF_ACCESSMODE_READWRITE, MF_OPENMODE_DELETE_IF_EXIST, MF_FILEFLAGS_NONE, L"D:\Documents\test.mp4", outputStream.put()));
winrt::com_ptr<IMFMediaSink> mp4StreamSink;
winrt::check_hresult(MFCreateMPEG4MediaSink(outputStream.get(), m_videoOut.get(), NULL, mp4StreamSink.put()));
winrt::com_ptr<IMFSinkWriter> sinkWriter;
winrt::check_hresult(MFCreateSinkWriterFromMediaSink(mp4StreamSink.get(), m_containter_attributes.get(), sinkWriter.put()));
sinkWriter->SetInputMediaType(0, m_videoIn.get(), nullptr);

二、使用MFCreateSinkWriterFromURL #

winrt::com_ptr<IMFSinkWriter> pSinkWriterVideo;
winrt::check_hresult(MFCreateSinkWriterFromURL(L"D:\Documents\test2.mp4", NULL, m_containter_attributes.get(), pSinkWriterVideo.put()));
winrt::check_hresult(pSinkWriterVideo->AddStream(m_videoOut.get(), &m_videoStreamIndex));
// 当尺寸非标准时出错
winrt::check_hresult(pSinkWriterVideo->SetInputMediaType(m_videoStreamIndex, m_videoIn.get(), nullptr /*编码器属性*/));

兼容性问题 #

当MF_MT_FRAME_SIZE设为{1920, 1080}时，两种方式均可正常运行；但将其设为{1922, 1089}这类非标准尺寸时，仅MFCreateSinkWriterFromURL方式会在调用IMFSinkWriter::SetInputMediaType时执行失败。
