第 3 部分。 M4V 和 FLV 格式之间的差异

M4V 存储在您的 Apple iTunes 商店下载的最高视频质量。这种格式类似于 MP4，因为它们使用 MPEG-4 编解码器作为压缩器。但 M4V 视频受 Apple FairPlay DRM 版权保护。因此，以这种格式播放视频是很棘手的，因为如果您将它们插入到 iTunes 或 Quicktime Player 以外的媒体播放器上，它不会立即播放。通过将文件扩展名更改为 .mp4，可以在您的媒体播放器上访问未受保护的 M4V 文件。

相比之下，FLV 用于尽快通过网络传输视频和音频数据。 Flash Video 是每个 HTML 5 网站上最受青睐的格式。但是，由于 Adobe Flash 已经淘汰，这种格式已停止使用。但是，您仍然可以在下载或转换后在所需的媒体播放器插件上播放它。
