Closed larvata closed 4 years ago

larvata commented 7 years ago 
const mediaRecorder = new MediaStreamRecorder(stream);
mediaRecorder.bitsPerSecond = 128000;

I want to set the bitrate for the webm audio, but the recording file is always use the default bitrate. It seems the "bitsPerSecond" property is not passed to the MediaRecorder.

var recorderHints = {
    mimeType: self.mimeType
};

...

// starting a recording session; which will initiate "Reading Thread"
// "Reading Thread" are used to prevent main-thread blocking scenarios
try {
    mediaRecorder = new MediaRecorder(mediaStream, recorderHints);
} catch (e) {
    // if someone passed NON_supported mimeType
    // or if Firefox on Android
    mediaRecorder = new MediaRecorder(mediaStream);
}
