我正在尝试开发和应用程序，允许医生和患者能够使用名为 connectycube 的 Api 进行通信，聊天和视频通话工作，问题在于静音和视频。我已经实现了静音声音和视频的按钮，所有这一切都使用 jQuery 对话框，我第一次静音音频或视频作品，但是当我关闭对话框完成会话然后我用新会话打开对话框时，静音音频和视频不再工作，控制台中的消息是This.localStream is null
我的源代码：
const CREDENTIALS = {
appId: 'xxxxx',
authKey: 'xxxxx',
authSecret: 'xxxxx'
};
ConnectyCube.init(CREDENTIALS);
//This is a button in a main jquery dialog, this is the beginning of all
{
text: 'VideoCall',
click: function () {
$('#dv_progess').html('<div class="dv_progress">Connecting</div>').dialog('open');
ConnectyCube.createSession().then((session) => {
$('#dv_progess').dialog('close');
signup_user();
$('#dv_videocall').dialog('option', 'position', {my: 'right top', at: 'right top', of: window}).dialog('open');
}).catch((error) => {
console.log('Error=>' + JSON.stringify(error));

当我清理视频标签时，我认为问题出在函数finishCall()中，我不知道这是否是释放资源的正确方法。尽管如此，聊天和视频通话仍然有效。
如果有人有经验请帮助我，因为我没有找到任何解决方案，在此先感谢。
