第三篇、vlc-android之UDP组播使用
来源：互联网 发布：如何进入投行 知乎 编辑：程序博客网 时间：2024/05/17 02:13
vlc-android 非常的强大，目前我们主要是使用vlc来播送组播UDP TS流。类似地址：udp://@239.1.1.0:2860这样的地址。在此之前发现声音会卡顿，效果不太好。今天发现是底层驱动的问题。
但是在进行vlc stop时候不能进行资源释放，很是奇怪。明天解决这个问题。文章后续会继续整理！！！
---------------------------------------------------------------------------
针对此前遇到vlc stop时候不能进行资源释放，后来是参考了VLC-android的源码，
具体类文件目录是：
类的代码：看一下VLC是如何释放的，这样处理逻辑比较好。
