Possible to support audio recording?

[shi-yan]

I'm implementing an AI agent with audio input. What I found was that the webview doesn't seem to support audio recording:

This is undefined:

navigator.mediaDevices

my code:

  async function startRecording(): Promise<void> {
    const stream = await navigator.mediaDevices.getUserMedia({ audio: true });
    mediaRecorder = new MediaRecorder(stream);

    mediaRecorder.ondataavailable = (event: BlobEvent) => {
      if (event.data.size > 0) {
        audioChunks.push(event.data);
      }
    };

    mediaRecorder.onstop = async () => {
      const audioBlob = new Blob(audioChunks, { type: 'audio/wav' });
      audioChunks = [];
      //uploadAudio(audioBlob);
      console.log(audioBlob);
    };

    mediaRecorder.start();
  }

  function stopRecording(): void {
    if (mediaRecorder && mediaRecorder.state !== "inactive") {
      mediaRecorder.stop();
    }
  }

I wonder if there is a way to work around this, (preferably in js (cross-platform), not in rust)?

I should mention that the failure is on iOS, not on Mac.
