• Evolution #4559 : Découpage et rangement des CSS de l’espace privé

  29 avril 2021

  Bon, les divers ajustements des css du privé ont fait mettre le pied dans l’engrenage.

  J’en profite pour faire un tour d’horizon et noter ce qu’il resterait à faire.
  J’ajoute au cahier des charges le reformatage de css, si le but du rangement est de faciliter les interventions, la lisibilité du code en fait partie.

  Pour éviter les malentendus : la proposition est de rester en gros sur les bases du rangement actuel, en complétant et en ajustant un peu.
  Et plus loin dans le futur, en cas de tabula rasa je pousserais à adopter un rangement à la Integraal, pour ma part.

  Composant	Rangement	Formatage	Commentaire
  alertes	ok	ok
  bando	ok*	ok	Contient aussi les menus de navigation, à déplacer dans un composant dédié
  boutons	ok	ok
  box_skins	ok*	ok	À renommer en « box » tout court (le vieux box.css a été supprimé)
  clear	-	-	Contient quelques resets et des styles utilitaires (pour masquer, etc.). Doublon avec utils.css, fusionner les 2 ? Pour le reset, il y a déjà celui de meyer, par ailleurs.
  content	-	-	Contient beaucoup de choses. Les styles correspondant aux sections pourraient être rangées ailleurs (#pied, #chemin). Le #wysiwyg également sans doute.
  exceptions	-	-	S’il s’agit vraiment de règles spécifiques à des pages précises, renommer en « pages » ? Contient la liste des plugins → à déplacer ?
  forms	ok	ok
  grids	-	-	Encore utilisé ?
  icons	ok*	ok	Contient aussi les onglets, à déplacer dans un composant onglet.css
  layout	ok	-
  lists	ok*	-	Contient des composants qui pourraient être déplacés ailleurs : pagination, plan du site, menu-item + divers (.en-edition, ...)
  minipres	ok	-
  picker	ok	-
  reset	ok	-
  table	ok	-
  theme	-	-	Tout le contenu devrait être dispatché dans les composants adéquats. Ne laisser que des choses spéciales ne pouvant être rangées ailleurs.
  typo	ok*	-	Quelques styles pour les documents qui devraient être dans medias plutôt
  utils	ok	ok	Cf. commentaire sur clear.css
  vieilles_def	-	-	Vide (???)

• How to create readable file stream from multiple files

  9 septembre 2020, par lowcrawler

  Related to question : Add specific image files to ffmpeg video with fluent-ffmpeg

  


  Have array of file names that reside on network shares. Would like to turn them into a timelapse video with a process on a nodejs server. I plan to use ffmpeg to do this. FFMPEG doesn't allow file lists as input (as far as I can tell). They do, however, allow a 'readable file stream'.

  


  Is there a mechanism to create a readable file stream from an array of filenames ?

  


  The command they use in the fluent-ffmpeg example is : var command = ffmpeg(fs.createReadStream('/path/to/file.avi'));

  


  ... but obviously, this is only a single file.

  


• Is it possible to send a temporary slate (image or video) into a running Azure Live Event RTMP-stream ?

  15 novembre 2020, par Brian Frisch

  I'm currently building a video streaming app which leverages Azure Media Services Live Events.

  


  It consists of :

  


  

  1. a mobile app that can stream live video and.

  


  2. a web client that plays the live event video.

  


  3. a producer screen with controls to start and stop the web client access to the video.

  


  4. a server that handles various operations around the entire system

  


  


  It's working very well, but I would like to add a feature that would enable the producer to add some elegance to the experience. Therefore I'm trying to get my head around how I can enable the producer be able to switch the incoming source of the stream to a pre-recorded video or event a still image at any point during the recording, and also to switch back to live-video. A kill-switch of some kind, that would cover waiting-time if there's technical difficulties on the set, and it could also be used for pre-/post-roll branding slates when introing and outroing a video event. I would like this source switch to be embedded in the video stream (also so it would be possible to get this into the final video-product if I need it in an archive for later playback)

  


  I'm trying to do it in a way where the producer can set a timestamp for when the video override should come in, and when it should stop. The I want to have my server respond to these timestamps and send the instructions over RTMP to the Azure Live Event. Is it possible to send such an instruction ("Hey, play this video-bit/show this image in the stream for x-seconds") in the RTMP-protocol ? I've tried to figure it out, and I've read about SCTE-35 markers and such, but I have not been able to find any examples on how to do it, so I'm a bit stuck.

  


  My plan-B is to make it possible to stream an image from the mobile application that already handles the live video-stream, but I'm initially targeting an architecture where the mobile app is unaware of anything else than live streaming, and this override switch should preferably be handled by the server, which is a firebase functions setup.

  


  If you are able to see other ways of doing it, I'm all ears.

  


  I've already tried to build a ffmpeg method that listens to updates to the producer-set state, and then streams an image to the same RTMP-url that the video goes to from the mobile app. But it only works when the live video isn't already streaming - it seems like I cannot take over a RTMP-stream when it's already running.
