Installation en mode ferme
4 février 2011, parLe mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
C’est la méthode que nous utilisons sur cette même plateforme.
L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...) -
Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...) -

Send info from ffmpeg to text file & then parsing into a new file
26 octobre 2023, par PrestonI am trying to scan a directory of .mkv files and output the volume information to out.txt and then parse out.txt for volume_max and send it to log.txt using


for %i in (*.mkv) do ffmpeg -i "%i" -af "volumedetect" -vn -sn -dn -f 1>> out.txt 2>&1 | findstr max_volume out.txt > log.txt



but I keep getting the error(s) :


Missing argument for option 'f'.
Error splitting the argument list: Invalid argument



when it runs the ffmpeg command.


I do get the out.txt file but it's not complete information for each file that's processed. Also, the log.txt file is always 0 bytes, I assume because out.txt doesn't get to the point of generating the max_volume information for each file before erroring.


I know it's got to be something simple but I can't see it. Can anyone shed a bit of light on what I might be doing wrong here ? Thanks !

Split VFR video into CFR chunks ?
17 janvier 2021, par Daniel L.Is there a good way to split a VFR video into chunks that split whenever the framerate changes ?


I have a video that I want to edit that is VFR but my editor doesn't support VFR. I don't want to set a constant framerate and convert it because that could degrade some sections of the video.


I was thinking that one way working with it would be to take it and split it into chunks that are CFR to work on separately (hopefully they'll be large sections).


I haven't found a good way to do it though, ffmpeg at least doesn't seem to have something built in to let me do it.


An alternative question would be : is there some software that would let me easily scan the video to find the framerates used ? If it's not too crazy, I can convert to a common multiple framerate, edit and then remove the duplicate frames with Avisynth later.

problem : FFMPEG seeking with av_seek_frame using byte positions
16 juillet 2012, par Nick VerlindenI am trying to get the av_seek_frame() function to go to a byte position I specify. I am implementing a frame accurate seeking mechanism for my application, and the way I see it, I will scan the entire video file, and store byte positions for each keyframe in a struct. I found out where to get the current byte position : AVPacket.pos. I now test this position with
av_seek_frame
like this :av_seek_frame( pFormatCtx, videoStream, 110285594, AVSEEK_FLAG_BYTE);
However, this does not seem to do the right thing, when I call
av_read_frame
, it just starts with frame 23. If I do not seek, it starts at frame 1.
