• Live streaming Rmtp node-media-server real server not creating video files but wont fail (OBS)

  3 octobre 2020, par Orgil

  I have made a live streaming server with node-media-server and it works well in local but when i put it on a real server (ubuntu, nginx) its just creating the folder but not creating video files and no errors given OBS the streaming sofware not failing. is it something to do with ffmpeg ? maybe needed packages didnt install or ? idk whats going on :D

  


  Cofig of node-media-server :

  


  rtmp_server: {
    rtmp: {
        port: 1935,
        chunk_size: 60000,
        gop_cache: false,
        ping: 60,
        ping_timeout: 30
    },
    http: {
        port: 8088,
        mediaroot: '/home/ubuntu/projects/amjilt_media/media',
        allow_origin: '*'
    },
    trans: {
        ffmpeg: '/usr/bin/ffmpeg',
        // ffmpeg: 'C:/Users/User/Desktop/ffmpeg/bin/ffmpeg.exe',
        tasks: [
            {
                app: 'live',
                hls: true,
                hlsFlags: '[hls_time=2:hls_list_size=3:hls_flags=delete_segments]',
                dash: true,
                dashFlags: '[f=dash:window_size=3:extra_window_size=5]'
            }
        ]
    }

  libavformat/dashdec : Support negative value of the @r attrbute of S in SegmentTimeline element.
  The following patch supports parsing negative value of the @r attribute of S in SegmentTimeline element.
  Example streams :
  
  1. http://dash.edgesuite.net/dash264/TestCases/1c/qualcomm/1/MultiRate.mpd
  
  2. http://dash.edgesuite.net/dash264/TestCases/1c/qualcomm/2/MultiRate.mpd

• FFMpeg command line to create specific MPD Manifest

  22 février 2024, par Seth Haberman

  I have tried to get an FFMpeg command to yield the below manifest. Right below is the FFmpeg command that I have tried to make but it has not created the same manifest file as what I am trying to replicate a stream from a third party system to add my own stream to their system so that it will actually play back.

  


  "$ffmpeg_path" \
    -i "$input_file" \
    -r 30000/1001 \
    -vf "scale=3840:1080" \
    -c:v libx265 \
    -c:a aac -b:a 128k \
    -ar 48000 \
    -f dash \
    -use_timeline 1 \
    -use_template 1 \
    -init_seg_name "init-stream\$RepresentationID\$.m4s" \
    -media_seg_name "chunk-stream\$RepresentationID\$-\$Number%05d\$.m4s" \
    -seg_duration 3 \
    "$output_file"


  


  The code above yields a manifest that is structured like below.

  


  &lt;?xml version="1.0" encoding="utf-8"?>&#xA;<mpd xmlns="urn:mpeg:dash:schema:mpd:2011" profiles="urn:mpeg:dash:profile:isoff-live:2011" type="static" mediapresentationduration="PT1M35.1S" maxsegmentduration="PT3.0S" minbuffertime="PT16.8S">&#xA;    <programinformation>&#xA;    </programinformation>&#xA;    <servicedescription>&#xA;    </servicedescription>&#xA;    <period start="PT0.0S">&#xA;        <adaptationset contenttype="video" startwithsap="1" segmentalignment="true" bitstreamswitching="true" framerate="30000/1001" maxwidth="3840" maxheight="1080" par="32:9">&#xA;            <representation mimetype="video/mp4" codecs="hev1" bandwidth="2227590" width="3840" height="1080" sar="1:1">&#xA;                <segmenttemplate timescale="30000" initialization="init-stream$RepresentationID$.m4s" media="chunk-stream$RepresentationID$-$Number%05d$.m4s" startnumber="1">&#xA;                    <segmenttimeline>&#xA;                        <s t="0" d="247247"></s>&#xA;                        <s d="250250" r="9"></s>&#xA;                        <s d="104104"></s>&#xA;                    </segmenttimeline>&#xA;                </segmenttemplate>&#xA;            </representation>&#xA;        </adaptationset>&#xA;        <adaptationset contenttype="audio" startwithsap="1" segmentalignment="true" bitstreamswitching="true">&#xA;            <representation mimetype="audio/mp4" codecs="mp4a.40.2" bandwidth="128000" audiosamplingrate="48000">&#xA;                <audiochannelconfiguration schemeiduri="urn:mpeg:dash:23003:3:audio_channel_configuration:2011" value="1"></audiochannelconfiguration>&#xA;                <segmenttemplate timescale="48000" initialization="init-stream$RepresentationID$.m4s" media="chunk-stream$RepresentationID$-$Number%05d$.m4s" startnumber="1">&#xA;                    <segmenttimeline>&#xA;                        <s t="0" d="143360"></s>&#xA;                        <s d="144384" r="29"></s>&#xA;                        <s d="93120"></s>&#xA;                    </segmenttimeline>&#xA;                </segmenttemplate>&#xA;            </representation>&#xA;        </adaptationset>&#xA;    </period>&#xA;</mpd>&#xA;&#xA;

  


  The problem is that I I need it to create a stream where the manifest looks like the manifest below. If it doesn't look or function as below, it will not playback correctly on this third parties system.
