我想使用ffmpeg将RTP流转码为MP4（HTTP）流，因此我可以在html视频标签中播放，

但我只能成功转码为flv格式。

以下是我的设置：

[在/ etc / ffserver.conf] 

...

<Feed feed1.ffm>
  File /tmp/feed1.ffm
  FileMaxSize 5M
  ACL allow localhost
</Feed>

<Stream flv>
  Feed feed1.ffm
  Format flv
  VideoFrameRate 40
  VideoBitRate 128
  VideoSize 1920x1080
  AVOptionVideo flags +global_header
  AudioBitRate 24
  AudioChannels 2
  AudioSampleRate 44100
  AVOptionAudio flags +global_header
</Stream>

<Stream mp4>
  Feed feed1.ffm
  Format mp4
  VideoFrameRate 40
  VideoBitRate 128
  VideoSize 1920x1080
  AVOptionVideo flags +global_header
  AudioBitRate 24
  AudioChannels 2
  AudioSampleRate 44100
  AVOptionAudio flags +global_header
</Stream>

<Stream avi>
  Feed feed1.ffm
  Format avi
  VideoFrameRate 40
  VideoBitRate 128
  VideoSize 1920x1080
  AVOptionVideo flags +global_header
  AudioBitRate 24
  AudioChannels 2
  AudioSampleRate 44100
  AVOptionAudio flags +global_header
</Stream>

[命令] 

$ ffserver -d -f /etc/ffserver.conf

$ ffmpeg -i MY_RTP_SOURCE  http://localhost:8090/feed1.ffm

[其他信息]

  1. 输入格式
    2. 
$ ffprobe -i MY_RTP_SOURCE

我终于得到了解决方案！

使用ffserver（将rtp流转换为http）+ videojs（以html播放flv视频）

我的/etc/ffserver.conf 

HTTPPort 8090
HTTPBindAddress 0.0.0.0
MaxHTTPConnections 2000
MaxClients 1000
MaxBandwidth 40000
CustomLog -

UseDefaults

<Feed feed1.ffm>
    File /tmp/feed1.ffm
    FileMaxSize 50M
</Feed>

<Stream stream>
    Feed feed1.ffm
    Format flv
    VideoFrameRate 24
    VideoBitRate 32768
    VideoSize 1280x720
    AVOptionVideo flags +global_header
    AudioBitRate 24
    AudioChannels 1
    AudioSampleRate 44100
    AVOptionAudio flags +global_header
</Stream>

我的命令

ffserver的

$ ffserver -d -f /etc/ffserver.conf

的ffmpeg

$ ffmpeg -i rtp://MY_RTP_RESOURCE http://localhost:8090/feed1.ffm

这可能会对您有所帮助：FFMPEG - RTMP to HLS no audio output

您可以使用rtp输入从这里开始工作，检查分段选项，因为您需要的是HLS输出格式
