• PC Video Conferencing in the Year 1999

  21 juin 2011, par Multimedia Mike — General

  Remember Intel’s custom flavor of H.263 cleverly named I.263 ? I think I have finally found an application that used it thanks to a recent thrift shop raid— Intel Video Phone :

  
  
  

  The root directory of the disc has 2 copies of an intro.avi video. One copy uses Intel Indeo 3 video and PCM audio. The other uses I.263 video and an undetermined (presumably Intel-proprietary) audio codec — RIFF id 0x0402 at a bitrate of 88 kbits/sec for stereo, 22 kHz audio. The latter video looks awful but is significantly smaller (like 4 MB vs. 25 MB).

  This is the disc marked as "Send it to a friend...". Here’s the way this concept was supposed to operate :

  • You buy an Intel Video Phone Camera Pack (forgotten page courtesy of the Internet Archive) which includes a camera and 2 CDs.
  • You install the camera and video phone software on your computer.
  • You send the other CD to the person whom you want to be able to see your face when you’re teleconferencing with them.
  • The other party installs the software.
  • The 2 of you may make an internet phone call presumably using commodity PC microphones for the voice component ; the person who doesn’t have a camera is able to see the person who does have a camera.
  • In a cunning viral/network marketing strategy, Intel encourages the other party to buy the physical hardware as well so that they may broadcast their own visage back to the other person.

  If you need further explanation, the intro lady does a great job :

  
  
  

  I suspect I.263 was the video codec driving this since Indeo 3 would probably be inappropriate for real time video applications due to its vector quantizing algorithm.

• Show Filename in Video ffmpeg batch script

  19 mars 2019, par Oli Shingfield

  I have a folder with around 10 different mov files. I would like to add the filename as text on each of the videos using ffmpeg in a bat file. Could someone help me achieve this please ?

  EDIT :

  I have tried using

  @ECHO OFF&Setlocal EnableDelayedExpansion
  
  Set INPUT=E:\\Users\\Oli\\Documents\\Projects\\v1.3.0\\downloads3
  
  Set OUTPUT=E:\\Users\\Oli\\Documents\\Projects\\v1.3.0\\downloads3
  
  for %%a in ("%INPUT%\*.*") DO ( 
  
      set "filename=%%~na"
  
      ffmpeg -i "%%a" -vf "drawtext=text=!fileName:.= !:x=105:y=120:fontfile=E:\\Users\\Oli\\Documents\\Projects\\v1.3.0\\downloads3\\impact.ttf:fontsize=25:fontcolor=white" -b:v 1M -r 60 -b:a 320k -ar 48000 -crf 17 "%%~na.mov"
  
  )`

  But it gives me the error :

   Cannot find a valid font for the family Sans
  
  [AVFilterGraph @ 0000026eb75a9f40] Error initializing filter 'drawtext' with args 'text=FileName1'

• Revision 101359 : Logiquement, il y a peu de chance qu’une personne ne mette pas à jour ...

  27 décembre 2016, par spip.franck@… — Log

  Logiquement, il y a peu de chance qu’une personne ne mette pas à jour facteur alors qu’elle mettrait les plugins le nécessitant, mais ainsi, cela réduit encore un peu plus le fait que des gens aient une version de facteur avec un problème de sécu !
  ​https://zone.spip.org/trac/spip-zone/changeset/101345
  Je n’ai fait que les plugins qui "necessite" facteur en 3.x.x. minimum de peur que cela pose problèmes avec les autres.
  Donc faudrait que les auteurs des plug qui "necessite" facteur en version mini 1.x.x. ou 2.x.x. sans borne max fasse la modif eux même ou me dise que je puisse le faire s’ils n’ont pas le temps
