• Evolution #3692 : Suivre les évolution de MediaJS

  28 juin 2017, par Franck D

  Hello, juste pour dire que la version 4.2.2 vient de sortir https://github.com/mediaelement/mediaelement/blob/master/changelog.md
  J’ai pas fait de test, Il y a pas mal de corrections de bugs, mais aussi la mise à jour de l’API Facebook. Elle était en 2.6 et passe en 2.9 !
  https://github.com/mediaelement/mediaelement/commit/8a5760dc6ca3fe5c32eb26f44142e579d718128a
  L’intérêt de mettre à jour la lib, c’est que cela fonctionne, après le 13 juillet 2018 https://developers.facebook.com/docs/apps/changelog

  Nous ne mettons pas souvent à jour les libs, (sauf sécu ou gros bug) dans les versions mineures de spip, et nous ne sortons pas souvent de mise à jour "majeure" (avec un peu de chances, la 3.3 sortira d’ici juillet 2019), c’est pour cela que je pense que cela serait une bonne idée de mettre la nouvelle lib, car sinon, une fonction ne fonctionnera plus dès l’année prochaine :-(

• ffmpeg input image list with timestamp in filename

  21 juillet 2019, par leonard vertighel

  How can I convert a list of input .png images which contain an ISO time stamp in their filename ?

  ffmpeg -y -f image2 -pattern_type glob -i '*.png' output.mp4

  do not manage colons : in a ISO-format filename such as 2018-01-29T06:43:21.png, and other solutions only allow aaa%03d.png file names such as aaa001.png.

• ffmpeg version 2.6.8 : Stream specifier ':a' in filtergraph description matches no streams

  16 décembre 2020, par Ashitaka

  I am not getting why this isn't working.. I have tried to get the video streams with [0:v]/[0:1]/[0:v:0] & the audio streams with [0:a]/[0:0]/[0:0:0].
nothing worked.

  


  Explaining the inputs :

  


  1.1st input stream is a video that can be of varying resolution on which the filter adds a padding on to make it 600:480.

  


  2.2nd input is an overlay png which is already at 5:4 ratio.. just making it 600:480 before it gets overlaid in the filter.

  


  3.3rd & 4th ones are also videos which I don't care if they get stretched.. n they are getting stretched to 600:480.

  


  4.so finally there are 3 streams 1 overlaid video 2 stretched videos which needs to be concatenated.

  


  here's the command :

  


  ffmpeg 
-i '/home/vidinflux/public_html/assets/temp/2018020116464612/2018020116464612.mp4'
