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.

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

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.

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.
