  • Other interesting software

    13 avril 2011, par

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Mise à disposition des fichiers

    14 avril 2011, par

    Par défaut, lors de son initialisation, MediaSPIP ne permet pas aux visiteurs de télécharger les fichiers qu’ils soient originaux ou le résultat de leur transformation ou encodage. Il permet uniquement de les visualiser.
    Cependant, il est possible et facile d’autoriser les visiteurs à avoir accès à ces documents et ce sous différentes formes.
    Tout cela se passe dans la page de configuration du squelette. Il vous faut aller dans l’espace d’administration du canal, et choisir dans la navigation (...)

  • why doesn't ffmpeg name files with sequence after using strftime ?

    5 décembre 2016, par user2030856

    I would like to know why ffmpeg stops naming my files with a sequence number (%03d) when using -strftime 1 ?

    for example : filename_%Y-%m-%d_%03d.ts

    I need to get filename_YEAR_MONTH_DAY_SEQUENCE#.ts

  • Fast seeking ffmpeg multiple times for screenshots

    7 mars 2017, par user3786834

    I have come across http://askubuntu.com/questions/377579/ffmpeg-output-screenshot-gallery/377630#377630, it’s perfect. That has done exactly what I wanted.

    However, I’m using remote URLs to generate the screenshot timeline. I do know it’s possible to fast seek with remote files using https://trac.ffmpeg.org/wiki/Seeking%20with%20FFmpeg (using -ss before the -i) but this only runs the once.

    I’m looking for a way to use the

    ./ffmpeg -i input -vf "select=gt(scene\,0.4),scale=160:-1,tile,scale=600:-1" \
    
-frames:v 1 -qscale:v 3 preview.jpg

    command but using the fast seek method as it’s currently very slow when used with a remote file. I use PHP but I am aware that a C method exists by using av_seek_frame, I barely know C so I’m unable to implement this into a PHP script I’m writing. So hopefully, it is possible to do this directly with ffmpeg in the PHP system() function.

    Currently, I run seperate ffmpeg commands (with the -ss method) and then combine the screenshots together in PHP. However, with this method it will be refetching the metadata each time and a more optimized method would be to have it all happen in the same command line because I want to reduce the amount of requests made to the remote url so I can run more scripts in sequence with each other.

    Thank you for your help.
