Unable to read a specific file H.264 file using Media Foundation Library (Application stall)

Upanita Goswami 1

I am from MathWorks and using the Media Foundation Library for reading video files on Windows from MATLAB. Recently, a customer of ours reported a H.264 video file that is stalling MATLAB when reading the file. Debugging our code showed that the method ReadSample of IMFSourceReader is blocking the application forever. Is this a known issue and how to workaround the problem? I am attaching the video file with the ticket. Also Windows Media Player cannot open this file either.

The API that is blocking:
IMFSourceReader::ReadSample method from this page https://video2.skills-academy.com/en-us/windows/win32/api/mfreadwrite/nf-mfreadwrite-imfsourcereader-readsample,

Note that we can read many other files correctly using the ReadSample API.

I have the video file but I am unable to attach a .avi file here

Hello @Upanita Goswami , we need some information to narrow down this issue, can you help to confirm?

Where the H.264 file comes from? How does it generate?

Is this issue reproduced with all H.264 files or a specific one?

What condition triggers this issue recently? Any change made in the customer environment?
