Stackoverflow

All source codes I've provided on stackoverflow as an answer, usually under tags ms-media-foundation. Most of the source codes here are quick fixes to source code from people asking for help. So be careful, it's not necessarily the most appropriate way to do it. That just answers the question. It' s up to the user to improve the code.

In the programs below, some values are harcoded, like video file path for example :

#define VIDEO_FILE L"C:\\Users\\Public\\Videos\\Sample Videos\\Wildlife.wmv"

Dont't forget to change them, if you use a different video file, in a different path.

AudioSourceReaderSeek

This program uses SourceReader to check seek position with audio file.

CustomVideoMixer

This program shows the basic essentials for implementing a custom video mixer, to be used by a media session.

You must register the CustomVideoMixer.dll with this command, and with the administrator rights : regsrv32 CustomVideoMixer.dll.

Be careful, the width and height of both videos are hardcoded (320x240). See VIDEO_WIDTH_1 and VIDEO_HEIGHT_1, change it if necessary.

In this example, I use two identical mp4 files, big_buck_bunny_240p_5mb.mp4 and a copy of itself. the two videos use NV12 video format as input. therefore, there is no real alpha mix, but both videos can be displayed next to each other, as the picture below.

FrameRateConverterDSP

This program shows how to use the Frame Rate Converter DSP (CLSID_CFrameRateConvertDmo), using a Source Reader. You can change the frame rate of a video stream. For example, if the video has 30 fps, you can get 60 fps.

MinimalSinkRenderer

This program shows the basic essentials for implementing a custom sink renderer, to be used by a Media Session. The stream sink format is MFVideoFormat_RGB32.

You must register the MinimalSinkRenderer.dll with this command, and with the administrator rights : regsrv32 MinimalSinkRenderer.dll.

TranscodeMp4ToMp4

This program transcode a mp4 video file into a new mp4 file, using mp4 Sink Writer and a Media Session with topology. There is no real encoding process, because output file has the same format as input file. The concept was to show how to setup IMFTopologyNode for both audio and video.
