![]() ![]() The MPEG4 specification defines several profiles, each of which specifies the tools that an encoder can use to generate an encoded stream. ![]() You can obtain a pointer to the IMFRateControl or IMFRateSupport interface by calling MFGetService and passing the service identifier MF_RATE_CONTROL_SERVICE. You can obtain a pointer to the IMFQualityAdvise or IMFQualityAdvise2 interface by calling QueryInterface on the MFT. You can obtain a pointer to the IMFTransform interface by calling CoCreateInstance, and you can obtain a pointer to the IMFAttributes interface by calling IMFTransform::GetAttributes. If you create an instance of the MPEG2 Part 2 Video decoder as an MFT, the decoder exposes the following interfaces. You can obtain an IMediaObject interface by calling CoCreateInstance, and you can obtain an ICodecAPI interface by calling QueryInterface. If you create an instance of the MPEG4 Part 2 Video decoder as a DMO, the decoder exposes the following interfaces. MPEG2VIDEOINFO (Only the VIH2 portion of the header is used.).The MPEG4 Part 2 Video decoder accepts the following formats. The MPEG4 Part 2 Video decoder supports the following output media subtypes when it is acting as an MFT. The MPEG4 Part 2 Video decoder supports the following output media subtypes when it is acting as a DMO. The MPEG4 Part 2 Video decoder supports the following input media types. To create an istance of the decoder that behaves as a Media Foundation Transform (MFT), use the class identifier CLSID_CMpeg4sDecMFT. To create an instance of the decoder that behaves as a DirectX Media Object (DMO), use the class identifier CLSID_CMpeg4sDecMediaObject. You can create an instance of the MPEG4 Part 2 Video decoder by calling CoCreateInstance. If non of this alternatives fixes your issue, then download a DVD Decoder Plug-in,which i placed a link at the bottom of the post.Īlso here are some articles that will help you troubleshoot the problem as well as to find out the spefici codec needed to install to be able to play the MPEG File.The MPEG4 Part 2 Video decoder decodes video streams that were encoded according to the MPEG4 Part 2 standard. If by downloading the latest codecs automatically did not work, then you can try downloading Windows Encoder 9, Make sure you have your Media Player set to download codecs automaticallyĬlick the arrow below the Now Playing tab, and then click More Options. ![]()
