Hi,

In order to properly determine why this is occurring, would you be able to collect traces while reproducing the error you have mentioned.

Instructions are as follows:

Logs Using latest mftracelog.exe

1. Download  
    - Download mftracelog.zip https://github.com/microsoft/media-foundation/releases/download/V1/mftracelog.zip
    - Unzip the downloaded file to obtain mftracelog.exe for x86, arm64 and amd64 platforms
    - Identify your machine's platform (amd64, x86, arm64) and open the corresponding folder   
2. Start tracing and reproduce the issue
    - If the repro involves Edge browser, close all Edge browser sessions
    - Launch mftracelog.exe by double-clicking on the file in File Explorer
    - Select "Simple" and "Full Traces" radio button in the mftracelog.exe UI and click "Start Tracing" button. 
    - Reproduce the issue. Try to capture the repro in less than 2 minutes, if possible, to avoid large trace file.
3. Stop tracing:
    - Click "Stop Tracing" button.  
    - This will generate several output files. File Explorer will automatically open to show four files. 
    - Select all four files and select "compress to zip file" through right-click menu to create a zip file  
4. Share the zip file

You can just change the file name in MediaEngineDCompWin32Sample.cpp to repro the issue. That is what this trace is from.

MPEG2 video playback via the store codec pack is not supported in the sample app as it configures the MediaEngine to run in a browser compatibility mode:

THROW_IF_FAILED(creationAttributes->SetGUID(MF_MEDIA_ENGINE_BROWSER_COMPATIBILITY_MODE, MF_MEDIA_ENGINE_BROWSER_COMPATIBILITY_MODE_IE_EDGE));

You should be able to get MPEG2 video to play by removing the above line from MediaEngineWrapper::CreateMediaEngine in MediaEngineWrapper.cpp.

[DougRogers]

When that line is removed, the playback rate cannot be changed for videos that have played with no issues.

The video uploaded to this report does not play, either. Did you test it?
