• How to fix "FFmpeg command cannot work when multiple mp3 file to process into one" on server side

  9 février 2019, par Harshil Dholakiya

  I am using FFmpeg in my php yii2 project. FFmpeg working fine in my project but one major problem is execute FFmpeg command with multiple input file. When i try to use single file to process in ffmpeg command then it works. so, how can i fix this problem ? I am using hostGator shared plan for my project. Please, help if is there any process limit or file open limit on server that i don’t know.

  I have tried using this command in php exec() :

  ffmpeg -y -i /uploads/ac/10122018-09351115-a94rlvlawvikskb4vdrca.mp3 -i /uploads/ac/09012019-035928988-assknyrk8oujccwevir7.mp3 -f lavfi -i anullsrc -filter_complex "[2]atrim=duration=3[g0];[2]atrim=duration=1[g1];[2]atrim=duration=5[g2];[g0][0][g1][1][g2]concat=n=5:v=0:a=1" /uploads/jm/concat.mp3 2>&1

  Above command works local side but not working on server side.

  output on server side with error code 1:

• Evolution #4300 (Nouveau) : Rendre facultatif les plugins-dist

  1er mars 2019, par Franck D

  Hello :-)
  Le commit de toutati https://zone.spip.net/trac/spip-zone/changeset/114194/spip-zone m’a fait repenser à ce vieux sujet (2009) https://blog.spip.net/SPIP-Core-tout-change-rien-ne-change.html
  Jluc avait fait un sujet à ce propos https://contrib.spip.net/plugins-dist-indispensables-ou-non
  Je me doute que cela représente un boulot de malade... mais ne faudrait’il pas dire au moins dans la F.A.Q. https://www.spip.net/fr_rubrique170.html les plugins-dist qui sont encore obligatoire ?

  J’ai fait le choix de "evolution" et non de "documentation" concernant le ticket, car sans ticket personne n’y pense :-D
  Pour spip 3.3, c’est sans doute un peu tard, mais à chaque sortie majeure, ne serait’il pas possible de rendre au moins "un" plugins-dist optionnel ?

  Pour le moment, en spip 3.3 [24240], il y a comme plugins-dist https://zone.spip.net/trac/spip-zone/browser/spip-zone/_core_/plugins
  Mais tous ne sont pas obligatoirement installer avec la dist (grenier, ?)
  Faudrait rayer les plugs qui sont en options

• FFMPEG fails with only two input frames

  3 mars 2019, par JeffThompson

  I’d like to use ffmpeg’s great frame interpolation to blend two images. I get great results when testing with about a dozen frames, but when only using two it finishes immediately and I get a video file that can’t be opened.

  My command :

  ffmpeg -y -r 24 -pattern_type glob -i "TestFrames/*[0-1].png" -pix_fmt yuv420p -filter:v "minterpolate='mi_mode=mci:mc_mode=aobmc:me_mode=bidir:vsbmc=1:fps=1024'" -vsync 2 8.mp4

  Output from ffmpeg :

  (Why fps=1024 ? I wanted to generate a a bunch of frames between the two images, so I plan to later separate the resulting video into separate images.)
