• Anomalie #3697 (Fermé) : Bug svn10000 SPIP 3

  14 février 2016, par MiKaël Navarro

  Bonjour,

  Je suis tombé sur un bug sur le processus de mise-à-jour de la base lors d’une migration vers SPIP3.

  En effet lorsque un dossier n’est pas présent (comme dans le cas d’une installation fraiche de SPIP 3.1 à partir du fichier Zip) on obtient des erreurs PHP qui remplissent les logs du serveur Web (dans mon cas Nginx) et saturent le disque.

  D’après la doc http://php.net/manual/fr/function.opendir.php, la fonction opendir renvoie False en cas de soucis et non une ressource. Il faut soit ignorer ce warning soit contrôler préalablement que le dossier existe :

  Cannot find a matching stream for unlabeled input pad 1 on filter Parsed_blend_1

  I’m a little noob with ffmpeg and I tryed to find a solution with google and don’t find.

  Without setsar=sar=1 I got the error about two different sar

  [Parsed_blend_0 @ 0x14bb0e0] First input link top parameters (size 1080x720, SAR 8:9) do not match the corresponding second input link bottom parameters (1080x720, SAR 1:1)
  
  [Parsed_blend_0 @ 0x14bb0e0] Failed to configure output pad on Parsed_blend_0

  Thanks for your help

• multiple ffmpeg instance with zmqsend

  6 février 2018, par liewjls

  By any chance anyone would able to point to the right direction, I have multiple ffmpeg instances running on the server and i need to change the configuration (for example change the volume) on the fly while the ffmpeg instance is running. I found this https://lists.ffmpeg.org/pipermail/ffmpeg-user/2016-September/033777.html which the zmqsend is the tool do the job.

  But how can i point the zmqsend sending the command to a specific ffmpeg instance ?

  I tried to run the zmqsend, but it got hanged.

  thanks.
