• avconv on debian jessie throws error when trying to convert raw video to mp4

  20 août 2017, par Vinay Divakar

  I am trying to convert a raw video captured using a Logitech USB Cam(YUYV) to mp4 using avconv. I have tried the below to do so :

  avconv -i out.raw -c copy output.mp4
  
  avconv -i out.raw -vcodec copy -acodec copy output.mp4

  but I get an error as shown below.

  root@beaglebone:~/BBB_CV/boneCV# avconv -i out.raw -c copy output.mp4
  
  avconv version 11.9-6:11.9-1~deb8u1, Copyright (c) 2000-2017 the Libav developersbuilt on Apr 23 2017 23:00:54 with gcc 4.9.2 (Debian 4.9.2-10)
  
  out.raw: Invalid data found when processing input

  I have checked here, but did not find any relevant examples for the above purpose.

  Edit : Added more details—

  I tried doing the below by adding the infile options as suggested :

  root@beaglebone:~/BBB_CV/boneCV# avconv -s 640x480 -framerate 30 -pix_fmt yuyv422 -f rawvideo -i out.raw -c copy output.mp4

  This got me rid of the previous error and some new ones popped up as shown below.

• Evolution #3751 : Ajouter le support du SNI au proxy connect

  24 août 2017, par - Equipement

  Je viens d’effectuer un test (en PHP 5.6) avec la version SPIP SVN du 24/08/2017. Lorsque je clique sur le bouton "Essayer le proxy", il n’y a plus de message d’erreur.
  Merci d’avoir résolu ce problème.
