VLC 媒体播放器作为一款由志愿者开发团队精心维护的自由、开源且跨平台的多媒体播放器能轻松驾驭绝大多数多媒体文件无论是本地磁盘中的视频、音频还是来自网络的流媒体协议. VLC for Android 支持网络串流无论是基于 HLS 的自适应流媒体还是 DASH 流都能稳定播放。对于有 NAS网络附属存储设备或者需要访问共享驱动器的用户而言它也提供了便捷的浏览支持。在兼容性方面其早期版本支持 Android 2.2 及以上而当前版本则要求 Android 4.2 及更高版本同时对 ARM v7、ARMv8/A arch 64、MIPS 和 x86 等多种硬件架构提供支持甚至还兼容 Android TV 大大拓展了其使用场景。
