看了你的代码，用canvas获取图片上传，那么音频怎么采样呢？

当网页通过websocket接收的图片数据，加载到img标签中时，网页内存占用率一直在增加，楼主有没有遇到这个问题，怎么解决的呢？

看了一下代码，发现用的是间隔截图发送服务器，再由服务器返回到其他页面，那么请问如果要有声音呢？

本地虚拟机CentOS 7，部署到服务器中时，关闭防火墙可以正常直播和观看，但是开启防火墙甚至设置防火墙规则就不行，观看页面无法收到数据。（没有更改代码的前提下，开放了8080和8088端口）
部署到阿里云的服务器上时，就算我完全关闭了防火墙，观看页面也无法显示视频。

手机firefox进行拍摄，WEB端看到的视频是倒着的，求大神解释下这个。

有明显卡顿，延迟，虽然知道这是个老项目了

cd /Users/ding/Desktop/live-camera

然后临时有事情走开了。

一个多小时后回来，我mac就报磁盘空间不足，我就奇了怪了，之前看还有一百多G，
于是查看了下，开始以为mac的bug。因为Machintosh HD 管理显示系统用了188G，然后过一会看，190G，就说明还在持续增加中。。。

后来，我找到/private/var/tmp/ 这个目录下占了一百多G，类似于/private/var/tmp/script.00785e 这类文件。
查了内容，就是一些xdebug对应php的信息，应该是调试信息吧

最后直接清掉/private/var/tmp/目录下的所有文件就搞定了。然后想起php相关的就是跑了下live-camera。
停止后没有问题了。

举个例子：
cat /private/var/tmp/script.0a6c3e
