Getting an error about writing opus headers, the codec is listed as available since enabling qputenv("QT_ENABLE_EXPERIMENTAL_CODECS", "1"_L1);

But I am getting an error could not write header, error: -1094995529 "Invalid data found when processing input"
QUrl("file:///C:/Users/Music/record_0001.ogv")

With

mediaFormat.setFileFormat(QMediaFormat::Ogg);
mediaFormat.setAudioCodec(QMediaFormat::AudioCodec::Opus);

Using wave works just fine:

mediaFormat.setAudioCodec(QMediaFormat::AudioCodec::Wave);

mediaFormat.setFileFormat(QMediaFormat::Wave);
