• Anomalie #3452 (Nouveau) : L’image jointe à un message de forum n’est pas prise en charge (bug SPI...

  18 mai 2015, par Pascal Verrier

  Bonjour,

  Depuis la MAJ toute récente de SPIP 3.0.19 je constate que l’image jointe à un message de forum n’est plus affichée après enregistrement du message.

  Le document est cependant bien créé dans la médiathèque mais n’est plus associé au forum.

  J’ai identifié le code responsable, dans plugins-dist/medias/action/editer_document.php lignes 260 à 267 : il s’agit d’un ajout depuis la 3.0.17 (ajout du même type également quelques lignes plus haut L252 avec "dissocierdocuments") :

     // verifier les droits d'associer<br />    foreach($objets_parents as $objet=>$ids){<br />        foreach($ids as $k=>$id){<br />            if (!autoriser('associerdocuments',$objet,$id)){<br />                unset($objets_parents[$objet][$k]);<br />            }<br />        }<br />    }<br />

  L’utilisateur courant devrait donc avoir le droit "associerdocuments" pour que l’image soit associée au forum. Or je suis connecté en tant que webmestre. Notez que par ailleurs notre forum peut également être utilisé par des "visiteurs" qui peuvent également joindre des images.

  En supprimant ce code l’image est de nouveau prise en charge normalement.

• Projecting camera feed with a delay

  28 septembre 2022, par Viktor Vošček

  I'm working on a project which involves capturing output from a camera via HDMI (Sony Alpha A7 IV), and projecting it via a laser/lamp projector, but the catch is that the stream which is going into the projector should be delayed by 4 minutes. (If you start recording something at 10:00am, it will start playing back at 10:04am, etc.) It should be capturing and playing back the feed non-stop for the whole day.

  


  First I was thinking of using FFplay to display a DirectShow stream from a HDMI capture card (like the Elgato 4K60 Pro) and opening the FFplay window on the 'projector screen', but I wasn't able to find any way to manually add delay to the stream. My second idea was to record the actual feed to a video file, and then immediately play it back in intervals (still using FFmpeg+FFplay).

  


  Any other ideas/thoughts ?

  


• Stream video and commands on same connection or split connections ?

  10 mai 2013, par bizzehdee

  Background

  I am in the middle of writing a client/server app that i will install on every machine within my office (roughly 30 - 35 machines). I currently have the client connecting to the server and it has an ability to send mouse movement, mouse clicks, key strokes and execute certain commands. The next step is to stream back a video output of the screen, i am using the GDI method from Fastest method of screen capturing to capture the entire screen and will be using the x264 encoder to compress the frames and transmit them back to the client which will then decode and display the stream.

  Question

  is it best (by means of reducing lag, ensuring all commands are delivered as fast as possible and that streaming is as live as possible) that i transmit back along the same connection that i established for the commands, or, should i establish a separate connection on the same port, or on a different port to stream back the video ?

  P.S.

  i am aware that VNC, RD and other things such as TeamViewer already exist and already do this sort of thing, but none of these support all the requirements needed for what we need within this system.
