• Connecting Firebase to a Computer to Run Programs for It [closed]

  29 mars 2020, par Rainbow Luv Sheep

  Currently I’m using Firebase to store video files sent by an app so that then ffmpeg can stitch them together and send a completed video back. However, ffmpeg will apparently sap up all of the allocated CPU usage of Firebase’s cloud functions since video files are large, and could possibly timeout. Because of that, I want to have Firebase sent a request to a computer that will download the video files, run ffmpeg to stitch them together, then upload that finished file back up to Firebase. App Engine and Compute Engine are out of scope due to cost .

  Is there any way to do that ?

  Sorry if I missed some obvious solution. I’m very new to working with servers in general.

• Encode and stream from Xbox 360 kinnect using ffmpeg

  17 juin 2015, par user3288346

  I want to live stream content obtained from Kinect onto my internal network.

  I have one physical machine which is my server and has ubuntu 14.04 on it. I connect remotely to it. I have installed ffmpeg and ffserver and can encode and stream stored video files on the server. However, I have a few problems when using the Xbox Kinect.

  I have xbox 360 kinect which I have attached through usb. I have followed this https://bitbucket.org/samirmenon/scl-manips-v2/wiki/vision/kinect, however I couldn’t get through the OpenCV part. When I run

  $ cmake-gui ..

  I get

  cmake-gui: cannot connect to X server 

  I don’t have physical access to the machine. Probably, its due to accessing it remotely.

  When I do

  test@cloud-node-2:~/kinnect$ lsusb

  Bus 002 Device 004: ID 045e:02b0 Microsoft Corp. Xbox NUI Motor

  Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub 

  When I do

  test@cloud-node-2:~/kinnect$ ls -ltrh /dev/video*
  
  ls: cannot access /dev/video*: No such file or directory

  Therefore, I am not able to capture the video using ffmpeg. I have only begun to work on this. Can someone help me to guide through this ?

• Anomalie #3418 : Les tables des plugins ne s’installent pas

  4 juin 2015, par b b

  Bon, j’ai une mauvaise nouvelle, je confirme ce qu’annonce Franck.

  Installation de SPIP 3.1.0-beta [22198] sur un mutu ovh avec la config suivante :

  app.engine=php
  app.engine.version=5.4
  http.firewall=none
  environment=production
  

  Après l’installation du plugin Agenda, j’ai l’erreur suivante quand je tente d’accéder à l’exec des événements :

  Erreur SQL HY000 / 1
  no such table : spip_evenements
  SELECT evenements.date_debut FROM spip_evenements AS ’evenements’ ORDER BY evenements.date_debut LIMIT 0,1

  La bonne nouvelle, c’est que si on ajoute +1 à la $duree comme le suggère Franck, ça fixe le bug. L’explication pourrait être que comme on fait un sleep de la durée de la fréquence d’invalidation du cache, et bien on retombe dedans. Non ?
