• error = "sh : /root/bin/ffmpeg : Permission denied

  6 août 2015, par user1503606

  Ffmpeg install location.

  Hi All i am running Centos 6.6 and i installed ffmpeg using this guide following each step.

  http://trac.ffmpeg.org/wiki/CompilationGuide/Centos

  But when i try and run.

  $output = shell_exec("cd {$targetDir} && /root/bin/ffmpeg -i {$fileName} {$wav} 2>&1");

  I get

  sh : /root/bin/ffmpeg : Permission denied

  After reading through lots of post i believe i should not have installed ffmpeg in /root/bin/

  How do i install it in say /usr/local/bin ?

  I ran this.

  PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure
  —prefix="$HOME/ffmpeg_build" —extra-cflags="-I$HOME/ffmpeg_build/include" —extra-ldflags="-L$HOME/ffmpeg_build/lib" —bindir="$HOME/bin" —pkg-config-flags="—static" —enable-gpl —enable-nonfree —enable-libfdk-aac —enable-libfreetype —enable-libmp3lame —enable-libopus —enable-libvorbis —enable-libvpx —enable-libx264 —enable-libx265

  Can someone let me know who i would do this thanks.

• nomenclature #3324 : Déplacer les fonctions typographiques dans un plugin séparé

  29 octobre 2014, par Fil Up

  Quelques autres améliorations à faire (pas très difficile, mais pointilleux : faire des cas tests).

  1. toujours rendre les espaces insécables (même en anglais) quand l’espace est déjà présente (a ! => a !)

  2. en français-français, ajouter les espaces insécables, mais pas en français-suisse (enfin, différemment)
  http://fr.wikipedia.org/wiki/Comparatif_des_différents_codes_typographiques_francophones#Diff.C3.A9rences_entre_les_typographies_fran.C3.A7aise_et_suisse

  3. remplacer les insécables qui vont bien par des fines (en option avec réglage ou define). Le code est déjà fait, il suffit de l’intégrer (avec les tests idoines) cf. http://core.spip.org/issues/1461

• parallel ffmpeg filter complex pipelines

  3 septembre 2021, par Paul Eppner

  Is there a possibility to run ffmpeg filter_complex filter in parallel pipelines ?
On the page http://trac.ffmpeg.org/wiki/Creating%20multiple%20outputs you can find an example under the heading "One filtering instance per each output". However, the filters mentioned there (boxblur,negate,yadif) are executed one after the other, although they could also all be executed simultaneously. I have quite complex filters and therefore long delays when the filters are executed one after the other.

  


  I hope there is another solution.
Cheers

  A few hours later I realised that the delay was probably not due to the pipeline, but to the analysis of the imports. However, I then only use the video and audio of the 1st stream. nevertheless, the delay time is then enormously high. Are there any ideas on how I can prevent this delay ?
