this one will be useful after adding one new overlay for each join live from a new person : when a given person speaks, the wave reacts only for the overlay of the speaking user.

oh excellent if i can apply that one for people who have already joined in the live https://obsproject.com/forum/resources/muted-notification.1706/

this one is even better : https://obsproject.com/forum/resources/scale-to-sound.1336/

ok alors là voilà clairement un plugin qui permet de faire du join live, en collaboration avec un serveur annexe, qui lui permet de chatter en vidéo audio : https://obsproject.com/forum/resources/camerapro-io-add-remote-video-feeds-into-obs.1578/

voilà un autre candidat encore plus sérieux :

• https://github.com/steveseguin/vdo.ninja apparrement ça ce serait la partie serveur séparée qui permet de faire un join live
• oui j'ai vérifié e c'est certain, ça marche

très intéressant celui là aussi pour lancer un compte-à-rebours: https://obsproject.com/forum/resources/boxing-rounds-browser-source-timer.1699/

[Jean-Baptiste-Lasselle]

celui là à la place de StreamFX : https://obsproject.com/forum/resources/3d-effect.1692/

[Jean-Baptiste-Lasselle]

pour que quelqu'un de la régie ait le contrôle uniquement sur une seule overlay, afin d'apporter des éléments à l'antenne, comme d'afficher un numéor , une adresse email, ou encore des données statistiques, ou aller sur google pour faire une recherche ?

séparer l'audio de la vidéo: https://obsproject.com/forum/resources/obs-recording-demuxer.1524/

[BorisTherin]

j'ai fouiller la doc de https://github.com/datarhei/restreamer ils utilsent ce player qui semble tres complet: https://github.com/clappr/clappr demo

concernant un pitch-meter: (detection de l'activité vocale pour le rendu cote overlay intervenants) https://makitweb.com/demos/pitch-volume-detection-in-speech-recognition-javascript

la page traite aussi de reconnaissance voicetotext (en anglais) mais on s'en fout.

leurs volume-meter.js script recupere un context audio (voir video pour nos besoin) & de là on pourra equiper notre overlay intervenants pour render qui s'exprime.

• volume-meter.js

Usage: audioNode = createAudioMeter(audioContext,clipLevel,averaging,clipLag);

audioContext: the AudioContext you're using. clipLevel: the level (0 to 1) that you would consider "clipping". Defaults to 0.98. averaging: how "smoothed" you would like the meter to be over time. Should be between 0 and less than 1. Defaults to 0.95. clipLag: how long you would like the "clipping" indicator to show after clipping has occured, in milliseconds. Defaults to 750ms.

Access the clipping through node.checkClipping(); use node.shutdown to get rid of it. */
