ffmpeg 和 ffserver 抛出错误，未获取流

Question

我正在尝试使用 ffmpeg 和 ffserver 流式传输我目录中的文件。但是ffmpeg和ffserver都报错了。以下是我的 ffserver 配置文件。

HTTPPort 8092
 HTTPBindAddress 0.0.0.0
 MaxHTTPConnections 2000
 MaxClients 1000
 MaxBandwidth 2000
 CustomLog -

<Feed feed1.ffm>
  File /tmp/feed1.ffm

</Feed>

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

  AudioCodec vorbis

  VideoCodec libvpx

  AVOptionAudio flags +global_header
  PreRoll 15
  StartSendOnKey
  VideoBitRate 400
  AudioSampleRate 44100           
</Stream>

我能够毫无问题地正确启动 ffserver，但是当我尝试使用 ffmpeg 为 ffserver 提供文件时，会发生这种情况

这是在 ffmpeg 中发生此错误时我在 ffserver 中收到的消息。

有人可以帮我吗？

Answer 1

如果您的目录中有该文件，您可以尝试跳过提要部分。这样，ffserver 将使文件准备好在服务器启动时进行流式传输，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"
...

如果您想先处理文件，您可能需要浏览提要。
