ffmpeg - 如何确定是否启用了 -movflags 快速启动？菲律宾比索

虽然我能够对可以在本地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等进行流式传输时可读。

经过一些阅读，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文件可流式传输。

为此，我试图找出我当前使用的ffmpeg版本是否能够通过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无法正常工作。

这就是我现在呼应 -help、-formats、-编解码器的方式，但我在任何列表中都没有看到任何关于 -movflags 快速启动的内容：

exec($ffmpegPath." -help", $codecArr);
for($ii=0;$ii<count($codecArr);$ii++){
    echo $codecArr[$ii].'</br>';
}

有没有类似的方法来确定 -movflags fastart 是否可用于我的 ffmpeg 构建？还有其他方法吗？它是否应与任何先前建议的命令一起列出？-帮助/-格式？

知道它已在其版本的ffmpeg中启用的人是否可以检查它是否列在-help或-formats等下？

编辑：转换命令和 -MOVFLAGS 命令的完整控制台输出如下：

命令：

ffmpeg -i C:\vidtests\Wildlife.wmv -s 640x480 C:\vidtests\Wildlife.mp4 

输出：
