• Best and latest live video streaming soloution [on hold]

  3 avril 2015, par Ford

  I have read a few old posts on StackOverflow about live video streamins, but as they are from around 2008, i assume things have moved on from then... and wonder if a current thread will be useful to me and others.
  Also looking on google gives lots of stuff, but again i dont know who is best to listen to and who is trying to sell their stuff (not that i am against paying).

  Basically what are the main points i need to know in order to add/develope a feature to a website in order to offer "1 on 1" and "1 to many" MULTIPLE live streaming webcam, with voice and text chat.

  I am quiet competent with PHP, OK with basic JavaScript (of course fine with HTMLL/css), but do not know what code i would need for client side software, or if any "off the shelf" software is suitable.
  I have played with ffmpeg and noticed this offers streaming, but i dont know if it would be suitable or the best available option.?
  I have a dedicated server with virtualization so can add a dedicated box for streaming if needed/better.

  Any info that can point me off in the right direction of how to add a live streaming service to a website would be much appreciated !

• How to get latest video frame without errors with FFMpeg ?

  3 mai 2021, par Kyryl Zotov

  I'm getting frame from video with FFMPEG and its working great except this when I want to get latest second frame.

  


  Video is 15.000 seconds.
But when I want exact that one or even 14.950 its not working.
When I try to get 14.800 it works, is there any way to setup ffpmeg to give closes result if it can't get frame ?

  


  My android library :
implementation 'com.arthenica:ffmpeg-kit-min:4.4.LTS'

  


  My Command
ffmpeg -ss 00:15:00.000 -i input -vframes 1 -q:v 2 output.jpg

  


  Error messages are :

• Anomalie #3501 (Nouveau) : Les forums supprimés restent en base

  6 juillet 2015, par Franck Dalot

  Bonjour
  Spip 3.1 [22301] mais aussi spip 3.0.20

  Lorsque l’on va dans ecrire/ ?exec=controler_forum&statut=off

  Les messages supprimés même très vieux sont toujours présent (suffit de voir contrib (2611 supprimés) le plus vieux semble du 7 décembre 2002)
  Logiquement, il faudrait que cela fasse comme les articles, qui après un certain temps (24 ou 48h, je sais plus) sont supprimés de la base

  Le problème est également présent concernant les "spams"
