• How to stream to the stream name come in response from Youtube livestream api

  7 décembre 2018, par Anirudha Gupta

  I am calling this API https://developers.google.com/youtube/v3/live/docs/liveStreams/insert ? to get stream name from Livestream API

  {
  
   "kind": "youtube#liveStream",
  
   "etag": "\"etag"",
  
   "id": "-ABa1o",
  
   "snippet": {
  
    "publishedAt": "2018-12-07T05:41:12.000Z",
  
    "channelId": "UC-
  
    "title": "Hello World",
  
    "description": "Snippet description of testing",
  
    "isDefaultStream": false
  
   },
  
   "cdn": {
  
    "format": "360p",
  
    "ingestionType": "rtmp",
  
    "ingestionInfo": {
  
     "streamName": "9qq0-ct85-ctub-",
  
     "ingestionAddress": "rtmp://a.rtmp.youtube.com/live2",
  
     "backupIngestionAddress": "rtmp://b.rtmp.youtube.com/live2?backup=1"
  
    },
  
    "resolution": "360p",
  
    "frameRate": "30fps"
  
   },
  
   "status": {
  
    "streamStatus": "ready",
  
    "healthStatus": {
  
     "status": "noData"
  
    }
  
   },
  
   "contentDetails": {
  
    "closedCaptionsIngestionUrl": "http://upload.youtube.com/closedcaption?cid=9qq0-ct85-ctub-",
  
    "isReusable": true
  
   }
  
  }

  I see a response like this, When I use OBS to stream to this RMTP URL it doesn’t have the title I set in the stream as you can see come in response. I am getting stream name but not sure if I do it correctly.

  If I call the path as rtmp://a.rtmp.youtube.com/live2/steamnamefromurl/mykey
  it’s work but not have the title I set by call API. Anyone please check the page and help what I am going wrong. What I am looking for is get the title and description set for stream, or verified that I am doing it correctly.

• No Audio when streaming to Youtube from ffmpeg

  11 février 2019, par Sindre Svendby

  So I’m not able to get sound to youtube when streaming with ffmpeg.

  The command I try to run ;

  ffmpeg \
  
   -f v4l2 \
  
   -vcodec h264 \
  
   -video_size 864x480 \
  
   -r 24 \
  
   -i /dev/video1 \
  
   -f alsa \
  
   -thread_queue_size 1024 \
  
   -ac 2 \
  
   -i plughw:CARD=C920,DEV=0 \
  
   -c:a aac \
  
   -filter:a "volume=1.5" \
  
   -b:a 128k \
  
   -ar 44100 \
  
   -vcodec copy \
  
   -b:v 2000k  \
  
   -r 24 \
  
   -g 48 \
  
   -x264opts no-scenecut \
  
   -bufsize 4096k \
  
   -maxrate 2048k \
  
   -f flv \
  
   rtmp://a.rtmp.youtube.com/live2/STREAM_KODE

  if I switch out the rmtp stream, with a file, like test.flv.
  And then I try to watch this with VLC I do get sound.

  If I check the audio codec in VLC I do see that the codec is aac.
  And as far as I can see from their help pages it is aac that is the correct audio codec to send in.

  I’m not sure how to continue debug this issue, and ideas on this would be great.

• exec RTMP stream to HLS nginx server not working

  26 février 2019, par Serg Port

  I’m trying to convert an RMTP stream to HLS using ffmpeg in an nginx server
  This is my basic nginx configuration.
  If use push rtmp ://localhost/show/ instead of exec is saving data, but exec it’s not doing nothing.
  I can see the stream with ffplay,
  error —> RTMP_ReadPacket, failed to read RTMP packet header
  rtmp ://localhost/live/key : Invalid data found when processing input
  To test it I’m using OBS and ffplay

  #user  root;
  
  worker_processes  auto;
  
  
  
  
  
  events {
  
      worker_connections  1024;
  
  }
  
  
  
  
  
  # RTMP configuration
  
  rtmp {
  
      server {
  
          listen 1935; # Listen on standard RTMP port
  
          chunk_size 4000; 
  
  
  
          # This application is to accept incoming stream
  
          application live {
  
              live on; # Allows live input
  
  
  
              # Once receive stream, transcode for adaptive streaming
  
              exec ffmpeg -i rtmp://localhost/$app/$name -async 1 -vsync -1 -c:v libx264 -c:a libvo_aacenc -b:v 256k -b:a 32k -vf "scale=480:trunc(ow/a/2)*2" -tune zerolatency -preset veryfast -crf 23 -f flv rtmp://localhost/show/$name_low 2>>/tmp/ffmpeg.error; 
  
          }
  
  
  
          # This application is for splitting the stream into HLS fragments
  
          application show {
  
              live on; # Allows live input from above
  
              hls on; # Enable HTTP Live Streaming
  
  
  
              hls_path /mnt/hls/;

              hls_variant _low BANDWIDTH=288000; # Low bitrate, sub-SD resolution
  
          }
  
      }
  
  }
