单击屏幕录制功能的“停止捕获”按钮时，弹出窗口不会消失

Question

I'm facing this trouble with popup. When I select "get audio from desktop" and click "Start Recording", another popup of browser appears, asking me for another decision ( It is about selecting the screen and sharing audio.I realize if I select "Sharing Audio" and click the blue button "share". It starts to record and a modal appears: "website is sharing the screen and audio " but If I stop the recording with clicking "Stop Capture" button, the modal of "Website is sharing... " still appearing. Could someone help me or explaining me if that is possible to disappear that modal when I click "Stop Capture". Thanks.

I leave the codepen link, the design is a bit disorder but It has the code about the functionality, thanks.

Answer 1

In your stop function, you stop all the tracks on this.stream . That includes the video tracks from the desktop stream, but only the audio tracks from the merged audio stream. The original, individual audio tracks from the desktop and the mic are not stopped, so as far as the browser knows they are still active.

Here is one way to stop the original streams:

new Vue({
  // ...
  data () {
    return {
      // ...
      individualAudioStreams: [],
      // ...
    }
  },
  methods: {
    startBtn() {
      // ...

      const mergeAudioStreams = (desktopStream, voiceStream) => {
        // ...
        if (desktopStream && desktopStream.getAudioTracks().length > 0) {
          // ...
          this.individualAudioStreams.push(desktopStream)
        }
        if (voiceStream && voiceStream.getAudioTracks().length > 0) {
          // ...
          this.individualAudioStreams.push(voiceStream)
        }
        // ...
      }

      // ...
    },

    stop() {
      // ...
      this.individualAudioStreams.forEach(s => s.getTracks().forEach(t => t.stop()))
      this.individualAudioStreams = []
      // ...
    }
  },
})
