Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...) -

YouTube Live Broadcast silence detect
12 mai 2020, par MarkusI'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 ?
