RecordRTC issue while using it with Angular material and universal (SSR)

[rajibhalder]

Is RecordRTC not compatible with Angular material and universal (SSR). Though with Angular material and CSR it is working fine. I added a conditional check isPlatformBrowser(platformId) for initializing recordRTC, but it seems the error occurs if i uncomment below code:

  this.recorder = new RecordRTC.StereoAudioRecorder(this.stream, {
        type: "audio",
        mimeType: "audio/webm",
      });

or
this.recorder = new RecordRTC();

Getting some CSS related error.
