Question

我正在尝试使用ffmpeg和ffserver来传输我目录中的文件。但是ffmpeg和ffserver都发生错误。以下是我的ffserver配置文件。

HTTPPort 8092
 HTTPBindAddress 0.0.0.0
 MaxHTTPConnections 2000
 MaxClients 1000
 MaxBandwidth 2000

</Stream>

我可以正常启动ffserver但没有问题，但是当我尝试使用ffmpeg为文件服务ffserver时，会发生这种情况

当ffmpeg发生此错误时，这是我在ffserver中收到的消息。

有人可以帮帮我吗？

Answer 1

如果您的目录中有该文件，则可以尝试跳过供稿部分。这样，ffserver将使文件在服务器启动时为流式传输做好准备，而您不必使用ffmpeg - 命令。

而不是：

<Stream live.webm>      
Feed feed1.ffm
...

使用：

<Stream live.webm>
Format webm         #if needed
File "sam.webm"
...

如果您想先操作文件，可能需要浏览Feed。

ffmpeg和ffserver抛出错误，而不是获取流
