Question

async toggleVideoCam() {

    if (this.rtc.localVideoTrack) {
      await this.rtc.client.localVideoTrack.setEnabled(false);
      this.rtc.localVideoTrack.close();
      document.getElementById('localvideo').remove();
    } else {
      await this.rtc.client.localVideoTrack.setEnabled(true);
    
      const playerContainer = document.createElement('div');
      const userIdContainer = document.createElement('span');
      userIdContainer.className = 'user-id-holder';
      playerContainer.className = 'localUserVideo';
      let liveStreamContainer = document.querySelector('.videoTracks-container');

      playerContainer.id = 'localvideo';
      userIdContainer.innerHTML = 'local video';
      playerContainer.append(userIdContainer);

      if (!document.getElementById(playerContainer.id)) {
        liveStreamContainer.append(playerContainer);
        // Play the local audio and video tracks
        // SDK dynamically creates a player in the container for playing the local video track
        this.rtc.localVideoTrack.play(playerContainer);
      }
    }
  }

现在我要切换发布localVideoTrack怎么办？是的，我在localVideoTrack上添加了setEnabled方法，但无法读取未定义的setEnabled属性。

您可以简单地使用适当的布尔值在本地轨道上调用@echo off echo Changing the Directory to Blue Prism Automate cd C:\Program Files\Blue Prism Limited\Blue Prism Automate echo Triggering CSM Validation Process and Storing the Session ID for /f %%i in ('AutomateC.exe /resource BWD14195034 /port 8215 /sso /run "CSMValidationInput"') do set RESULT=%%i For /f "delims=:" %%A in ("%RESULT%") do Set Session_ID = %%A echo %Session_ID% Pause方法来切换发布轨道。 https://agoraio-community.github.io/AgoraWebSDK-NG/api/en/interfaces/ilocalvideotrack.html#setenabled

第一件事是您必须将 await 与 setenabled 方法一起使用，第二件事是客户端对象中不存在轨道。

  try {
              if (this.rtc.localVideoTrack) await rtc.localVideoTrack.setEnabled(true);  // This is used to publish camera
          } catch (error) {
            console.log(error, 'error');
          }
        }
        else {
          try {
            if (this.rtc.localVideoTrack) await rtc.localVideoTrack.setEnabled(false); // With this you can close camera
          } catch (error) {
            console.log(error, 'error');
          }
        }

如何停止使用agora web sdk ng发布视频轨道/音频轨道？
