ffmpeg - ffserver - 无效的编解码器名称 libvpx

Question

我有以下 ffserver.conf 配置:

Port 8090                      # Port to bind the server to
BindAddress 0.0.0.0
MaxHTTPConnections 2000
MaxClients 1000
MaxBandwidth 10000             # Maximum bandwidth per client
                               # set this high enough to exceed stream bitrate
CustomLog -
NoDaemon                       # Remove this if you want FFserver to daemonize after start

<Feed feed1.ffm>               # This is the input feed where FFmpeg will send
   File ./feed1.ffm            # video stream.
   FileMaxSize 1G              # Maximum file size for buffering video
   ACL allow 127.0.0.1         # Allowed IPs
</Feed>

<Stream test.webm>              # Output stream URL definition
   Feed feed1.ffm              # Feed from which to receive video
   Format webm

   # Audio settings

   AudioBitRate 64             # Audio bitrate

   # Video settings

   VideoSize 720x576           # Video resolution

   AVOptionVideo flags +global_header  # Parameters passed to encoder
                                       # (same as ffmpeg command-line parameters)
   AVOptionVideo cpu-used 0
   AVOptionVideo qmin 10
   AVOptionVideo qmax 42
   AVOptionVideo quality good
   AVOptionAudio flags +global_header
   PreRoll 15
   StartSendOnKey
   VideoBitRate 400            # Video bitrate
</Stream>

<Stream status.html>            # Server status URL
   Format status
   # Only allow local people to get the status
   ACL allow localhost
   ACL allow 192.168.0.0 192.168.255.255
</Stream>

当我使用该配置文件运行服务器时，出现以下错误:

ffserver.conf:8: NoDaemon option has no effect. You should remove it.
ffserver.conf:13: ACL refers to invalid host or IP address '#'
ffserver.conf:26: Invalid codec name: 'libvpx'
ffserver.conf:31: Option not found: 'cpu-used'
ffserver.conf:31: If 'cpu-used' is a codec privateoption, then prefix it with codec name, for example 'vp8:cpu-used 0' or define codec earlier.
ffserver.conf:34: Option not found: 'quality'
ffserver.conf:39: Setting default value for audio sample rate = 22050. Use NoDefaults to disable it.
ffserver.conf:39: Setting default value for audio channel count = 1. Use NoDefaults to disable it.

我怎样才能成功运行它？我想流式传输实时 webm 视频，但到目前为止，我一直停留在启动 ffserver 的点上。

ffmpeg 列出任何调用的配置选项，并且没有 --enable-libvpx您的配置中的选项。尝试使用 --enable-libvpx 构建 ffmpeg .
