Video \Audio Container是什么？
视频、音频和容器是多媒体文件的三个主要组成部分：
-
视频（Video）：视频是由一系列连续的图像帧组成的，每秒播放的图像帧数称为帧率。视频可以使用不同的编码格式进行压缩，以减小文件大小并提供更高的传输效率。
-
音频（Audio）：音频是由声波信号组成的，包括声音的振幅、频率和持续时间等信息。音频也可以使用不同的编码格式进行压缩，以减小文件大小并提供更高的传输效率。
-
容器（Container）：容器是一种文件格式，用于封装和存储视频、音频和其他多媒体元素。容器格式可以同时包含视频、音频、字幕、元数据等多个流，并提供对这些流进行管理和同步的功能。常见的容器格式有MP4、AVI、MKV、MOV等。
容器格式提供了一种结构化的方式来组织和管理视频、音频和其他相关数据，使其能够在各种设备和平台上进行播放和交互。它们还支持各种编解码器和音视频参数设置，以适应不同的需求和场景。
