Chrome crashes on h.264 dual stream

[uctakeoff]

When I run the sample code basicVideoCall.js with some modifications, and repeat Join and Leave, Google Chrome often freezes.

OS: Windows 10 Pro
Chrome Version: 92.0.4515.131（Official Build） （64 bit）

The modifications are as follows.

• Create an RTC client with h.264, dualstream

  var client = AgoraRTC.createClient({ mode: "rtc", codec: "h264" });
  client.enableDualStream().then(() => {
    console.log("Enable Dual stream success!");
    client.setLowStreamParameter({
      bitrate: 256,
      framerate: 1,
      width: 160,
      height: 90,
    });
  }).catch(err => {
    console.err(err);
  });

• Add parameters to AudioTrack and VideoTrack.

    [ options.uid, localTracks.audioTrack, localTracks.videoTrack ] = await Promise.all([
      // Join the channel.
      client.join(options.appid, options.channel, options.token || null, options.uid || null),
      // Create tracks to the local microphone and camera.
      AgoraRTC.createMicrophoneAudioTrack({
        AEC: true,
        AGC: true,
        ANS: true,
        encoderConfig: {
          bitrate: 128
        }
      }),
      AgoraRTC.createCameraVideoTrack({
        encoderConfig: {
          width: 1920,
          height: 1080,
          bitrateMin: 1000,
          bitrateMax: 2000,
          frameRate: 30,
        }
      })
    ]);
