@Olivier-Duguay can you update to a more recent version of Qt ? Since 6.5, the default backend has been switched to ffmpeg which may give better results.

@SGaist That is correct. The same application tested on different Windows machines presents exactly the same behavior.

@Chris-Kawa said in QMediaRecorder(QMediaFormat) not support wave format:

Is that on Windows? By default Qt uses Windows Media Foundation backend, which does support PCM audio in WAV containers, but for some reason this format doesn't seem to be mentioned in the windows platform plugin. I don't know if it's a omission by mistake or intentional. You might want to ask the developers on the mailing list.

Qt 6.4 introduced experimental ffmpeg backend that seems to at least mention this format in the code. It's a technology preview, so you might need to compile it yourself though. Target platform and backend notes.

Yes, I use Qt6.2.4 on Win 11.

Thanks for you reply.

I'm as surprised as you that I don't have at least one codec... I'll try installing other codecs packages and have a look at VLC's Qt Wrapper but I mainly choose to use QMediaRecorder to reduce any other inclusion of librairies.

Thanks for the info, I'll keep you up-to-date.

Hi and welcome to devnet,

You have an example on how to use QAudioProbe in the detailed documentation of the class. As for measuring the level of a silent user, it's a completely other topic, you'll have to take into account the noise of the environment of the user.

You might want to check the libqtavi library: https://iondev.ro/qtavi/

It enables Qt based applications to easily save video files in the AVI container format and is available under two licenses: open-source (GPL v. 3.0) and commercial.

Hi and welcome to devnet,

The nicest thing to do would be as stated in the TODO: get the information from the video encore settings control and rebuilt the plugin.

From a quick look at the sources, it seems so yes currently
