虽然我可以对可以在本地 Windows 机器上播放的 mp4 文件进行编码，但我在将文件编码为 mp4 时遇到问题，这些文件在通过 safari 等流式传输时可读。
经过一番阅读，我相信我的问题是我必须将元数据从文件末尾移动到开头，以便转换后的 mp4 文件可以流式传输。
为此，我试图找出我当前使用的 ffmpeg 构建是否能够通过 php 使用 -movflags 快速启动选项 - 因为我当前输出的 mp4 文件在在线流式传输时不起作用。
这就是我现在呼应 -help、-formats、-codecs 的方式，但我在任何列表中都没有看到任何关于 -movflags faststart 的信息：
exec($ffmpegPath." -help", $codecArr);
for($ii=0;$ii<count($codecArr);$ii++){
echo $codecArr[$ii].'</br>';
}
是否有类似的方法来确定 -movflags fastart 是否可用于我的 ffmpeg 构建？还有什么办法吗？它是否应该与之前建议的任何命令一起列出？-帮助/-格式？
知道它在他们的 ffmpeg 版本中启用的人是否可以检查它是否列在 -help 或 -formats 等下？
TIA。
编辑：下面的转换命令和 -MOVFLAGS 命令的完整控制台输出：
命令：
ffmpeg -i C:\vidtests\Wildlife.wmv -s 640x480 C:\vidtests\Wildlife.mp4
