Video recording saves the files in m4a instead of video formats

[Enayat]

Hi,

I have been working on a recording application. The camera is analog and its data is converted to digital using ADV7280m in embedded linux. I am supposed to record the camera data with some overlay including text and some PNG files. I can display the camera feed with overlays on the screen, but when I execute recorder.record() and afterwards, recorder.stop() functions, I see a record_001.m4a file written at $HOME directory instead of a video file.

First of all, how can I specify the output file format in QML?
Secondly, how can I record the cameraItem view in QML with the overlays I mentioned?

Thanks in advance.

@Enayat I see mediaFormat mentioned in the doc for MediaRecorder but the documentation appears to be incomplete. Perhaps dig into this a bit?
