Streamer

Streamer是SRS作为服务器侦听并接收其他协议的流(譬如RTSP,MPEG-TS over UDP等等),将这些协议的流转换成RTMP推送给自己,以使用RTMP/HLS/HTTP分发流。

Use Scenario

常见的应用场景包括:

  • Push MPEG-TS over UDP to SRS:通过UDP协议,将MPEG-TS推送到SRS,分发为RTMP/HLS/HTTP流。
  • Push RTSP to SRS:通过RTSP协议,将流推送到SRS,分发为RTMP/HLS/HTTP流。
  • POST FLV over HTTP to SRS: 通过HTTP协议,将FLV流POST到SRS,分发为RTMP/HLS/HTTP流。

备注:Streamer将其他支持的协议推送RTMP给SRS后,所有SRS的功能都能支持。譬如,推RTSP流给Streamer,Streamer转成RTMP推送给SRS,若vhost是edge,SRS将RTMP流转发给源站。或者将RTMP流转码,或者直接转发。另外,所有分发方法都是可用的,譬如推RTSP流给Streamer,Streamer转成RTMP推给SRS,以RTMP/HLS/HTTP分发。

Build

编译SRS时打开StreamCaster支持,参考Build

./configure --with-stream-caster

Protocols

目前Streamer支持的协议包括:

  • MPEG-TS over UDP:已支持,可使用FFMPEG或其他编码器push MPEG-TS over UDP到SRS上。
  • Push RTSP to SRS:已支持,可以使用FFMPEG或其他编码器push rtsp to SRS
  • POST FLV over HTTP to SRS: 已支持,可用于AndroidPublisher推流。

Config

The config for stream casters:

# the streamer cast stream from other protocol to SRS over RTMP.
# @see https://github.com/simple-rtmp-server/srs/tree/develop#stream-architecture
stream_caster {
    # whether stream caster is enabled.
    # default: off
    enabled         off;
    # the caster type of stream, the casters:
    #       mpegts_over_udp, MPEG-TS over UDP caster.
    #       rtsp, Real Time Streaming Protocol (RTSP).
    #       flv, FLV over HTTP POST.
    caster          mpegts_over_udp;
    # the output rtmp url.
    # for mpegts_over_udp caster, the typically output url:
    #       rtmp://127.0.0.1/live/livestream
    # for rtsp caster, the typically output url:
    #       rtmp://127.0.0.1/[app]/[stream]
    #       for example, the rtsp url:
    #           rtsp://192.168.1.173:8544/live/livestream.sdp
    #           where the [app] is "live" and [stream] is "livestream", output is:
    #           rtmp://127.0.0.1/live/livestream
    output          rtmp://127.0.0.1/live/livestream;
    # the listen port for stream caster.
    #       for mpegts_over_udp caster, listen at udp port. for example, 8935.
    #       for rtsp caster, listen at tcp port. for example, 554.
    #       for flv caster, listen at tcp port. for example, 8936.
    # TODO: support listen at <[ip:]port>
    listen          8935;
    # for the rtsp caster, the rtp server local port over udp,
    # which reply the rtsp setup request message, the port will be used:
    #       [rtp_port_min, rtp_port_max)
    rtp_port_min    57200;
    rtp_port_max    57300;
}

Push MPEG-TS over UDP

SRS可以侦听一个udp端口,编码器将流推送到这个udp端口(SPTS)后,SRS会转成一路RTMP流。后面RTMP流能支持的功能都支持。

配置如下,参考conf/push.mpegts.over.udp.conf

# the streamer cast stream from other protocol to SRS over RTMP.
# @see https://github.com/simple-rtmp-server/srs/tree/develop#stream-architecture
stream_caster {
    enabled         on;
    caster          mpegts_over_udp;
    output          rtmp://127.0.0.1/live/livestream;
    listen          1935;
}

参考:https://github.com/simple-rtmp-server/srs/issues/250#issuecomment-72321769

Push RTSP to SRS

SRS可以侦听一个tcp端口,编码器将流推送到这个tcp端口(RTSP)后,SRS会转成一路RTMP流。后面RTMP流能支持的功能都支持。

配置如下,参考conf/push.rtsp.conf

# the streamer cast stream from other protocol to SRS over RTMP.
# @see https://github.com/simple-rtmp-server/srs/tree/develop#stream-architecture
stream_caster {
    enabled         on;
    caster          rtsp;
    output          rtmp://127.0.0.1/[app]/[stream];
    listen          554;
    rtp_port_min    57200;
    rtp_port_max    57300;
}

参考:https://github.com/simple-rtmp-server/srs/issues/133#issuecomment-75531884

Push HTTP FLV to SRS

SRS可以侦听一个HTTP端口,编码器将流推送到这个http端口后,SRS会转成一路RTMP流。所有RTMP流的功能都能支持。

配置如下,参考conf/push.flv.conf

# the streamer cast stream from other protocol to SRS over RTMP.
# @see https://github.com/simple-rtmp-server/srs/tree/develop#stream-architecture
stream_caster {
    enabled         on;
    caster          flv;
    output          rtmp://127.0.0.1/[app]/[stream];
    listen          8936;
}

这个配置时,客户端推流的地址,例如:http://127.0.0.1:8936/live/sea.flv
播放RTMP流地址是:rtmp://127.0.0.1/live/sea
播放HLS流地址是:http://127.0.0.1:8080/live/sea.m3u8

注意:需要配置HTTP服务器和HLS,参考conf/push.flv.conf
