Why and/or what is the origin of this resultcode?
I can't find anything that explains on docs what this result actually means and how to resolve this.
Thank you.
Could you please show a minimal, reproducible sample without private information to help us reproduce the issue?
Hi, I could, but that's not an answer to my question.
I only want to know what is causing this result code. Because it's not documented as a resultcode from IMFCaptureSource::GetAvailableDeviceMediaType nor what's the meaning or origine of this.
Thank you.
According to the information you provided, we couldn't determine what caused the MF_E_INVALIDREQUEST. So we need a sample to reproduce this issue, and to judge whether the document is missing or the call to the IMFCaptureSource::GetAvailableDeviceMediaType api is wrong.
Thank you.
The resultcode is not documented as a possible result of IMFCaptureSource::GetAvailableDeviceMediaType.
I can't give a sample without the whole code explained.
In the mean while this result is solved by implementing WaitForSingleObject(Event, INFINITE), before calling this method.
When IMFCaptureSource is created from IMFCaptureEngine::.GetSource the engine needs to sync because the IMFCaptureEngine methods are processed a-synchronous.
And that's the reason a HResult (0xC00D36B2) will be returned when IMFCaptureSource methods waits to be completed..
Now, it would be handy to add this resultcode and explanation here
Thank you.
I suggest you could submit a document feedback direct via click the icon button "This article is helpful/not helpful"
I think that's your job, otherwise this conversation had no meaning.

Hello, Tony.
Thank you for your decision! I'm facing the same problem. When I run "manually" through the code, the method IMFCaptureSource::GetAvailableDeviceMediaType works well, but when I start the program, I also get the error 0xC00D36B2. I suppose this is due to the fact that during manual debugging I slowly run through the instructions and some asynchronous methods have time to synchronize. If it's not too much trouble, could you describe in more detail what the problem is? For which event should WaitForSingleObject(Event, INFINITE) be called to solve the problem?
Thank you.
