nginx - 如何让 NGINX RTMP 模块存储流式 HLS？

Question

我正在使用带有 RTMP 模块的 NGINX 以 HLS 格式流式传输视频。我想让它存储以 HLS 格式流式传输的实时视频。我知道hls_cleanupRTMP 模块的指令，但是关闭清理并不能防止.m3u8被一遍又一遍地覆盖。如何让 NGINX 将新块附加到.m3u8文件而不是覆盖它？如果这不是解决此问题的正确方法，我还有哪些其他选择？

Answer 1

虽然答案可能有点晚，但我面临同样的挑战，因此考虑回答。简而言之hls_playlist_length就是解决方案。

hls_playlist_lenght 100d; #d = days y = years

您可能还想关闭hls_continious.

hls_continious off; # plays video from the beginning I assume.

但是，请注意，冗长的播放列表时间会使m3u8文件迅速膨胀到庞大的大小。因此，担心直播可能对服务器端和客户端都产生负面影响，我采取了以下方法。

application live {
    live on;
    hls on;

    on_publish http://example.com/auth/onpublish;
    on_update http://example.com/auth/onupdate;
    on_done http://example.com/auth/ondone;

    # Use some encrypted channel name to avoid unwanted streaming
    # Make sure the push channels publish only from localhost
    # 
    push rtmp://<ip>/livechannel_8jzh%6ifu....DZBVzdbdg12; 
    push rtmp://<ip>/hls_raid_8jzh%6ifu....DZBVzdbdg12;
}

直播设置（低延迟）

application livechannel_8jzh%6ifu....DZBVzdbdg12 {

    # Only allow localhost to publish
    allow publish 127.0.0.1; #!important

    hls on; 
    hls_path /path/to/live/hls_storage;
    hls_cleanup on; 
    # set play from present segment or
    # right from beginning. Default off
    hls_continuous on;
    # push stream to stream key directory
    hls_nested on;

    # Low latency optimisation
    # hls_sync 2ms;
    hls_fragment 2s;
    hls_playlist_length 6s;
}

保存完整的 hls 以备后用

application hls_raid_8jzh%6ifu....DZBVzdbdg12 {

    # Only allow localhost to publish
    allow publish 127.0.0.1; #!important

    live on;
    hls on;
    hls_nested on;
    hls_path /another/path/to/hls_raid;
    hls_cleanup off;
    hls_fragment 10s;
    hls_playlist_length 100d;# choose any large number
    hls_continuous off;

}
