Configuration spécifique pour PHP5

PHP5 est obligatoire, vous pouvez l’installer en suivant ce tutoriel spécifique.
Il est recommandé dans un premier temps de désactiver le safe_mode, cependant, s’il est correctement configuré et que les binaires nécessaires sont accessibles, MediaSPIP devrait fonctionner correctement avec le safe_mode activé.

Déploiements possibles

31 janvier 2010, par kent1

Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

ffmpeg - splitting, overlaying and selecting frame range in multiple input/outputs with complex video filter producing empty output

11 octobre 2017, par Josep Carner

I am trying to use ffmpeg to apply multiple filters -single input, multiple outputs-. In concrete, I am splitting the output in two, then applying an overlaying patch to one of those streams, split again and select a time range. The command I am using is :

   ffmpeg \

    -i ./dataset_test/videos/jz_10_huron_barstow.mkv \

    -an \

    -sn \

    -loglevel error \

    -filter_complex \

        "[0:v]split=2[L_in][F_in];

         [L_in]

            crop=226:307:21:74,scale=200x200,setdar=200:200,split=2\

         [L_in_0][L_in_1];\

         color=#808080:226x307,setpts=PTS-STARTPTS[L_PATCH];\

         [F_in][L_PATCH]

            overlay=21:74:shortest=1,scale=200x200,setdar=200:200,split=2\

         [F_in_0][F_in_1];\

         [F_in_0]select='between(t\,32\,212)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[F_0];\

         [F_in_1]select='between(t\,213\,393)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[F_1];\

         [L_in_0]select='between(t\,32\,212)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[L_0];\

         [L_in_1]select='between(t\,213\,393)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[L_1]\

         "\

    -map [F_0] -an -sn ./out/jz_10_huron_barstow/F/0_F.mp4\

    -map [F_1] -an -sn ./out/jz_10_huron_barstow/F/1_F.mp4\

    -map [L_0] -an -sn ./out/jz_10_huron_barstow/L/0_L.mp4\

    -map [L_1] -an -sn ./out/jz_10_huron_barstow/L/1_L.mp4\

For some reason, 0_F.mp4 is empty and 1_F.mp4 is cropped. My intuition is that it has something to do with applying splitting + overlaying + selecting. I think at some point some filter before select is changing the PTS of the frames in some way select is not properly discarding them, but I honestly don’t know how to solve it. Some insights :

L_0 and L_1 are fine (no overlay is used in those two)
If I suppress L outputs everything works fine (no "split" is needed at the beginning)

Could someone provide some light ? I don’t really know what else to try.
The logs with loglevel 40 are (some repeated lines ommited) :
