7-我看错了,我找不到为什么会发生这种事,也找不到我哪里出错了!

到目前为止,我阅读了许多有关ffserver的示例和教程,但大多数都是关于实时流的,但我只想流一些mp4文件。

编辑:

我安装了真正的ffmpeg,如以下链接: https://askubuntu.com/questions/373322/how-to-replace-avconv-with-the-real-ffmpeg-and-have-it-work-right ,但同样的错误(只需将ppa更改为 ppa:mc3man/trusty-media ,以便最后发布):

有人能给我准确的命令,我应该运行测试吗?

(我知道这就像初学者的问题,但我读了文档,并尽我所能测试一切,但仍然没有运气)

您不能使用ffserver对 mp4 进行流处理,因为它在文件头中包含全局元数据,这使得随机流访问变得不可能。您可以选择另一种格式,如 webm 或使用MPEG-2传输流(Apple的HLS).See https://superuser.com/questions/563591/streaming-mp4-with-ffmpeg
