FFMPEG流错误：无法使用正确的文件大小和持续时间

标签： ffmpeg streaming vlc

我正在尝试将mp4流式传输到本地计算机上的vlc播放器，地址为127.0.0.1:48550，但遇到此错误。 

Failed to update header with correct duration.
Failed to update header with correct filesize.

我在Mac上流式传输时没有遇到此问题，但是遇到了Windows PC。

在我的Mac上我正在运行ffmpeg 3.2.4，并在PC上使用gcc 7.1.0构建的ffmpeg版本N-86755-g0780ad9。

以下是VLC媒体播放器调试日志：

关于为什么会这样的想法？以及如何解决这个问题？

我在另一个线程中找到了这个问题的答案。

在混合flv文件结束时，FFmpeg使用持续时间和文件大小值更新标头（在文件的开头）。但是，当您进行流媒体播放时，ffmpeg无法向前搜索，因此会显示警告。

您可以通过添加一个标志（-flvflags no_duration_filesize）来禁用此功能，例如：
