请教 opus 音频 数据格式 网络传输
有人知道opus 吗
我网络抓包了一段数据 怀疑是opus 但不确定是否正确
有人帮我看看否
每个包数据 比较短
我打算把多个包的数据 头尾去掉
只保留裸数据 到一个文件尝试播放
但是我却不知道 opus 的数据结构 所以无法定位头从什么地方开始.
我每天都会来 看一次回复 如果能帮我 进行进一步分析可以加 华子N
留下联系
下图只包含了部署数据

Opus 的头部信息是固定的，由一个字节的版本号、一个字节的头部长度以及一个字节的保留位组成。可以查看 Opus 的协议规范文档了解更多有关 Opus 头部信息的细节。
在你的数据中，可以看到第一个字节是版本号，第二个字节是头部长度。可以通过这些信息确定头部信息的长度。例如，如果版本号是 100，头部长度是 2，则头部信息的长度是 3 字节（1 字节版本号 + 1 字节头部长度 + 1 字节保留位）。
接下来可以去除头部信息，只保留裸数据，然后将裸数据写入文件并尝试播放。
