MediaRecorder iOS 14.6: mimeType не поддерживается ⇐ IOS

[Гость]

I am recording and sending audio via a website. For that purpose I use the MediaRecorder API.
There are no issues when using the site on desktop or Android devices and according to the MediaRecorder documentation, since a release in September 2020, iOS 14 should be supported as well.
The MediaRecorder is instantiated like this:

Код: Выделить всё

navigator.mediaDevices.getUserMedia({ audio: true, video: false })
.then((stream) => {
// Some validation and other processing. Omitted for brevity.

const mediaRecorder = new MediaRecorder(stream, { mimeType: 'audio/webm' });

// Using the mediaRecorder. Omitted for brevity.
});

When doing this on an iPhone 12 with iOS 14.6, i get the following error from that instantiation line:

Код: Выделить всё

NotSupportedError: mimeType is not supported

I get the same error when trying other formats (these are the ones I found and tried):

• Код: Выделить всё

  audio/webm

  (as shown in example above)

• Код: Выделить всё

  video/webm

• Код: Выделить всё

  audio/ogg

  (also errors on desktop)

• Код: Выделить всё

  audio/ogg; codecs=opus

  (also errors on desktop)

Is there any mimeType for MediaRecorder that lets me use audio on iOS devices?
Am I getting something else entirely wrong?
