问题 Problem statement: Intel hardware MFT is not honoring the GOP setting, resulting in more bandwidth consumption in realtime applications. The same code works fine on Nvidia hardware MFT. Background: I'm trying to encode NV12 samples captured through DesktopDuplication APIs to video stream using MediaFoundation H264 hardware encoder on Windows10 machine, stream and render the same in real-time over LAN. Initially, I was facing too much buffering at the encoder as the encoder was buffering up to

How to create IMFSample for WindowsMediaFoundation H.264 encoder MFT

问题 I'm learning to use the H.264 encoder in Windows Media Foundation. What I currently have are media samples in YUV420p format, so that's buffers containing YYYYYYYYUUVV data. Since the H.264 encoder MFT requires input in form of IMFSample, I'm not sure how to convert the data in buffer into IMFSample. May I just do like this: IMFMediaBuffer *pBuffer = NULL; MFCreateMemoryBuffer(cbSize, &pBuffer); BYTE *pData = NULL; pBuffer->Lock(&pData, NULL, NULL); memcpy(pData, bufferIhaveinYYYYUV format,

问题 I'm struggling with mixing two audio streams into single output stream. MFNode has an AudioMixerMFT but TopoEdit crashes when I try to build a topology like this & execute it: Note: I tried TopoEdit that comes with Windows SDK 7.1 & also the one with few fixes by the author of "Developing Microsoft® Media Foundation Applications" I thought it could be some issue with TopoEdit so I built the Topology in code (by modifying the code from Ch#9 of "Developing Microsoft® Media Foundation
