• Using ffmpeg to restream youtube videos

  2 juin 2020, par ILoveCake

  I want to restream 3 youtube videos (each one is a live webcam) in this way : they would run one after the other, but each one runs for only 1 minute. All this in a loop. So my live stream would eventually look like this :
cam1, cam2, cam3, cam1, cam2, cam3, ...
I have tried to used youtube-dl and ffmpeg (these are my preferred command line tools) to download each stream, let it run for 1 minute and restream it. The problem is that I have to start ffmpeg each time. So when it stops and starts again, the live stream stops and starts again (after about 15 seconds). Here is my code (for bash) :

  



  The main script : (FILE is an array with the 3 URLs for the videos)

  



  for URL in "${FILE[@]}"
do
  timeout 1m /usr/local/bin/get_livestream.sh $URL
done



  



  and get_livestream.sh :

  



  youtube-dl -q -o - -- $1 | ffmpeg -re -loglevel warning -hide_banner \&#xA;  -i - -s 960x540 -c:v libx264 -b:v 2M -c:a copy \&#xA;  -strict -2 -flags &#x2B;global_header -bsf:a aac_adtstoasc -bufsize 2100k \&#xA;  -f flv rtmp://live.twitch.tv/app/<key>&#xA;</key>

  


• Discord.js Music Bot ffmpeg not found ?

  13 octobre 2020, par cccmdm

  I just started learning javascript with node.js and I am attempting to create a music bot, I've set up the command handler and everything, however, I keep getting this error when I try to run the play command

  



  


  Error : FFmpeg/avconv not found !

  I'll post my play function below

  



  async function playMusic(vc,songId) {
    const stream = await ytdl(songId,{type: 'opus',filter : 'audioonly'});
    vc.join().then(connection => {
        const dispatcher = connection.play(stream,{volume: 1});
        dispatcher.on('end', end => {
            console.log("Song ended!");
            vc.leave();
        }).catch(err => console.log(err));
    }).catch(err => console.log(err));
}

  Update 1 : I'm still looking for others with this specific problem and can't find anything.

  


• FFMPEG stream RTSP to RTMP (Youtube) add logo

  16 juin 2017, par Māris Purviņš

  To stream video from IP cam to Youtube I’m using code (through Ubunu) :
  ffmpeg -f lavfi -i anullsrc -rtsp_transport tcp -i rtsp ://user:psw@192.168.0.100:554 -tune zerolatency -vcodec libx264 -pix_fmt + -c:v copy -c:a aac -strict experimental -f flv rtmp ://a.rtmp.youtube.com/live2/ -nostdin -nostats /dev/null 2>&1 &

  It is a bee project for school
  I have two cameras and two streams :
  https://www.youtube.com/watch?v=ws-VcLXo-hI

  Everything is ok, but... I would like to know :
  1. How to add png logo to this strem. I have tried -i /home/user/rvvg_logo_round.png -codec:v libx264 -preset ultrafast -filter_complex overlay and another methods but without a result.
  2. Sometimes there is some problem during night and video streaming stops. How to automatically check process status and restart stream.
  I have tried to create sh file as described in http://videos.cctvcamerapros.com/raspberry-pi/ip-camera-raspberry-pi-youtube-live-video-streaming-server.html and put in cron job, bet that is only to check one cam process. Is there some better idea ?
