Unsolved Record sound and video using QMediaRecorder

[ClementD]

Hello,

I am using Win 10 and I would like to record video from a camera and sound-using microphone.
I have tried to use QMediaRecorder but it do not record.

Code: I’ll put the code tonight because I am not home.

Always return no recording state, no error and empty output location

Do someone have a working example?
Is QMediaRecorder is working on windows?
Do I have to be careful to each codec? Which I can use to record in avi/ mp4?

I had another Idea.
I succeed at recording audio using QAudioRecorder and at recording video using OpenCV

Do someone knows how I can merge sound and video into one file?
