我该如何修复这个问题？由于这种情况发生在 .mov 源文件而不是 .mp4 源文件上，我认为我没有设置正确的解码器。那么我需要重新编译吗？我需要使用什么设置？
我正在尝试使用 ffmpeg 将大多数用户上传的电影处理成所有 HTML5 支持的编解码器。当我上传 mp4 时它可以工作，但在 .mov 视频上会死机并显示错误。这是从终端运行相同命令时的完整输出。我使用的是 centos 6.3 64 位，因为我使用的是 cPanel。
ffmpeg -i Vails_in_the_Field.mov -b:v 300k -vcodec libx264 -g 30 -s 640x360 Vails_in_the_Field.mp4

我也尝试使用从 ffmpeg 页面链接的静态二进制文件，结果完全相同。

自 2013 年 5 月 17 日起，ffmpeg支持解码 Apple Intermediate Codec，标识为icod。
