使用 Flash Media Server，我有一个预制的应用程序，它从网络摄像头和麦克风记录并将其作为 FLV 文件发布到 FMS 服务器。

这很好用，但我现在需要将录制的视频流式传输到 iOS 设备。我有 FMS 工作，它可以将 hls-record/sample.f4v.m3u8 文件流式传输到 iOS / quicktime 设备。

我已经在线阅读了一些教程，并将 publish(filename, "record") 更改为 publish("mp4:" + filename + ".f4v", record)

它记录将文件存储在 FMS 服务器上（我在那里看到它，带有我给它的文件名，并作为 .f4v 文件），它有内容。当我开始播放它时（通过 quicktime 或 safari），我看到了视频的长度（4 秒作为测试）但没有视频。跟踪栏不移动，等待图标等待。

FMS 版本 4.5 和 Flash 11.3 安装在我的 Mac 上。（CentOS 5.8 服务器）

我肯定错过了什么。

我决定创建一个 php 脚本，该脚本位于包含 FLV 文件的文件夹中。通过 cron 作业，此 php 文件检查 mysql 数据库中进程标签为 1 的新视频。找到新视频了吗？对 FLV 文件执行 ffmpeg 以将其转换为 mp4 并将进程标记设置为 0。这样，我维护了用于桌面浏览器流式传输的 FLV 和用于 iOS 流式传输的 MP4 文件。如果我需要为 android 或任何可能出现的文件创建另一种文件类型，我可以在 cron 作业触发时简单地进行另一个 ffmpeg 转换。

这也将减少服务器上的开销。mp4 由 ffmpeg 编码一次 - 不是每次请求通过 FMS 流式传输文件时。现在 MP4 只是 Web 服务器上的另一个文件。
