  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • FFMPEG "Error setting GOP size" when converting from mp4 to ogg

    25 avril 2014, par gCardinal

    I built a little internal website to upload and convert videos using Symfony2, PHP-FFMPEG (via this bundle : https://github.com/pulse00/ffmpeg-bundle). It worked fine on my dev machine, a PC, but it refuses to work on my prod machine, a ubuntu server, outputting "[libtheora @ 0x17f7380] Error setting GOP size" whenever I run the command.

    Here is said command :

    ffmpeg -y -i url/to/input.mp4 -vcodec libtheora -acodec libvorbis -b:v 1000k -refs 6 -coder 1 -sc_threshold 40 -g 30 -flags +loop -me_range 16 -subq 7 -i_qfactor 0.71 -qcomp 0.6 -qdiff 4 -trellis 1 -b:a 128k url/to/output.ogg

    This is generated by PHP-FFMPEG so I don’t really have any control over it.

    I’ll admit that I don’t really understand ffmpeg, so my knowledge is limited, but I don’t see any -g parameter where it could be trying to set the GOP size and anyways, I’m guessing, if it worked on my dev, it should also work on the prod machine, right ?

    I figured I should maybe include an output of both ffmpeg versions : http://i.imgur.com/ec4MnKl.png

    I don’t feel like this is the source of the problem, but like I said, I know little about ffmpeg so it could be !

    Thanks a lot to anyone reading this and even more to those taking the time to answer :)

    Edit : I tried running the most basic command I could

    ffmpeg -i foo.mp4 foo.ogg

    And it outputs the same error. Again, with my limited knowledge, I’m starting to think my install of ffmpeg just can’t handle the ogg format. I’ll keep digging.
