    10 décembre 2010, par

    Pour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.

  • YouTube Live Broadcast silence detect

    12 mai 2020, par Markus

    I'm trying to monitor a YouTube live broadcast for silence to be able to restart ffmpeg broadcast. How would you achieve that without breaking the YouTube ToS ?

    



    I tried with the YouTube API, but health.status is only supported for Live streams but not for broadcast.

    



    I came up with the idea of youtube-dl, grabing the m3u8 and the run ffmpeg with silencedetect but now I'm somehow stuck.

    



    Get the formats

    



    youtube-dl --list-formats https://www.youtube.com/watch?v=BiHequcIiNw


    



    Get the m3u8 manifest

    



    youtube-dl -f 91 -g https://www.youtube.com/watch?v=BiHequcIiNw


    



    Run ffprobe

    



    ffprobe -v quiet -print_format json -show_streams https://manifest.googlevideo.com/api/manifest/hls_playlist/expire/1588936061/ei/Hem0Xp35EZLl1wLLhYaYCA/ip/2a02:1205:c6bb:4590:301f:6186:c624:f2ba/id/BiHequcIiNw.0/itag/91/source/yt_live_broadcast/requiressl/yes/ratebypass/yes/live/1/goi/160/sgoap/gir%3Dyes%3Bitag%3D139/sgovp/gir%3Dyes%3Bitag%3D160/hls_chunk_host/r3---sn-nfpnnjvh-9and.googlevideo.com/playlist_duration/30/manifest_duration/30/vprv/1/playlist_type/DVR/initcwndbps/13630/mh/GY/mm/44/mn/sn-nfpnnjvh-9and/ms/lva/mv/m/mvi/2/pl/48/dover/11/keepalive/yes/fexp/23882513/mt/1588914375/disable_polymer/true/sparams/expire,ei,ip,id,itag,source,requiressl,ratebypass,live,goi,sgoap,sgovp,playlist_duration,manifest_duration,vprv,playlist_type/sig/AOq0QJ8wRgIhALApv3H2YEE2GLTXIyRxw8Fu8espLgRThUfhi97DIS6-AiEAsT_4bwAfsihK6zsrKgaxMYTemlAr8BXnBTwuhwe3aAE%3D/lsparams/hls_chunk_host,initcwndbps,mh,mm,mn,ms,mv,mvi,pl/lsig/AG3C_xAwRQIgRG3c1ww23Jokzk6vfAfeZlhwEanWG_9GmwRip81v65cCIQDg1Y9pXWS4bUjpKpZ90c3icp4slmAzhQJPn2gqW0UOeQ%3D%3D/playlist/index.m3u8


    



    But I haven't found a difference in the json if the stream is up or down. Any hint how I could monitor the m3u8 if it's up or down ?

    


  • How can I use ffmpeg with youtube-dl ?

    18 octobre 2018, par Dani

    I have this "setup", but it stopped working (I did not change anything in the code) :

      private Process StartFfmpeg(string URL)
    
    {
    
        string args = $"/C youtube-dl --ignore-errors -o - {URL} | ffmpeg -err_detect ignore_err -i pipe:0 -ac 2 -f s16le -ar 48000 pipe:1";
    
        return Process.Start(new ProcessStartInfo
    
        {
    
            FileName = "cmd.exe",
    
            Arguments = args,
    
            UseShellExecute = false,
    
            RedirectStandardOutput = true,
    
            RedirectStandardError = false,
    
            CreateNoWindow = true,
    
        });
    
    }

    (I get the stream by using
    Stream stream = StartFfmpeg(URL).StandardOutput.BaseStream;)
    It just freezes. It doesn’t throw any error (in a try/catch block) and I have the latest version of ffmpeg & youtube-dl. I’ve tried using older versions with no success.
    How can I get it working again ? (This is my first post, sorry if its very bad)

  • Youtube-dl convert to MP3 multi cores [on hold]

    1er janvier 2017, par Top Games a-Z

    Do you know how to tell to youtube-dl to use all cpu cores when convert music (using ffmpeg) to mp3 ? Because it downloads the song but when it has to convert it uses just one core. Thank you.
