如何讓NGINX RTMP模塊存儲流式HLS？

Question

我正在使用帶有 RTMP 模塊的 NGINX 到 HLS 格式的 stream 視頻。 我想讓它以 HLS 格式存儲正在流式傳輸的實時視頻。 我知道 RTMP 模塊的hls_cleanup指令，但是關閉清理並不能阻止.m3u8被一遍又一遍地覆蓋。 如何為.m3u8文件制作 NGINX append 新塊而不是覆蓋它？ 如果這不是解決此問題的正確方法，我還有哪些其他選擇？

Answer 1

雖然答案可能有點晚，但我面臨同樣的挑戰，因此考慮回答。 總之hls_playlist_length是解決方案。

hls_playlist_lenght 100d; #d = days y = years

您可能還想關閉hls_continious 。

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

但是，請注意，播放列表時間過長會很快使m3u8文件膨脹到一個巨大的大小。 因此，擔心直播可能對服務器端和客戶端都產生負面影響，我采用了以下方法。

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;
}

直播設置（低延遲）

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 以備后用

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;

}
