更新：下载最新的 Windows 版本 (3.2.2)、使用基准 3.0 编码视频并将该视频上传到我们的测试环境后，最新视频确实可以在 OSX/Safari 以及 iPhone 6 上的 iOS/Safari 上播放。我认为唯一的解决方案就是催促我们的公司高层升级服务器上的 ffmpeg。感谢您的所有帮助，如果我在这件事上浪费了任何人的时间，我深表歉意。
在 iPhone（目前只尝试过 iPhone 6）和 MacBook 上的 Safari 上播放视频时遇到问题。这些视频在 Android 设备和 Windows 上的 IE11/Chrome 以及 Chrome/OSX 上播放正常。
仅供参考，这是视频播放器：
<video style="width:480px; height:320px" controls preload >
<source src="my_source_variable" type="video/mp4" >
</video>
这是我当前的编码：
ffmpeg -y -i #arguments.input# -c:v libx264 -crf 23 -profile:v baseline -level
3.0 -pix_fmt yuv420p -c:a aac -ac 2 -strict experimental -b:a 128k -s 480x274
#arguments.output#
以下是 ffmpeg 输出的示例：

由于我在这方面完全是新手，所以我只能依靠我的 Google 朋友的建议。上述编码是来自
并按建议使用，减去 faststart 标志。编辑：我删除了 faststart，因为使用“faststart”和“+faststart”编码均失败。相关输出示例：
[mp4 muxer @ 0x75d200] [Eval @ 0x7ffc607b1ae0] Undefined constant or missing '(' in 'faststart'
[mp4 muxer @ 0x75d200] Unable to parse option value "faststart"
[mp4 muxer @ 0x75d200] Error setting option movflags to value +faststart.
我将继续搜索和实验，同时等待答案的出现；-)但我现在唯一的线索是“不兼容的样本格式”警告，因为它只是一个警告，所以可能并不那么重要。
当我在 Web Inspector 中检查网络流量时，我发现状态、大小和传输字段为空白。没有控制台错误。
另外，当我尝试在 MacBook 上的 Safari 中直接访问该文件时，它无法加载，但在 Chrome 中可以加载。
PS 如下所述，我们的 ffmpeg 已经很古老了；我无法控制这一点。
编辑：根据建议，添加了 -an 标志；仍然无法在 iPhone 上播放；接下来转到 -vn 标志；
