MediaSPIP v0.2
21 juin 2013, parMediaSPIP 0.2 est la première version de MediaSPIP stable.
Sa date de sortie officielle est le 21 juin 2013 et est annoncée ici.
Le fichier zip ici présent contient uniquement les sources de MediaSPIP en version standalone.
Comme pour la version précédente, il est nécessaire d’installer manuellement l’ensemble des dépendances logicielles sur le serveur.
Si vous souhaitez utiliser cette archive pour une installation en mode ferme, il vous faudra également procéder à d’autres modifications (...) -

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 (...)

ffmpeg undefined reference to sws_getContext
23 septembre 2021, par Wenfei ZhuI am learning to use ffmpeg libraries, and have successfully compiled and run a program that demuxes and decodes a video. However, when I was trying to use the swscale library, I got a linking error "undefined reference to sws_getContext". There are similar problems on the Internet but none of them solves my problem.


The full error message is


/usr/bin/ld: CMakeFiles/ffmpeg_test.dir/main.cpp.o: in function `main':
main.cpp:(.text+0x44f): undefined reference to `sws_getContext'
collect2: error: ld returned 1 exit status
make[2]: *** [CMakeFiles/ffmpeg_test.dir/build.make:93: ffmpeg_test] Error 1
make[1]: *** [CMakeFiles/Makefile2:76: CMakeFiles/ffmpeg_test.dir/all] Error 2
make: *** [Makefile:84: all] Error 2


Here is my Dockerfile, source file and CMakeList.

Generating video from images and audio by FFmpeg
24 mars 2020, par CodyI am new to FFmpeg and video/audio encoding. I try to use Fluent ffmpeg to generate a MP4 video from images and audio.
There are 2 inputs only :
- JPG images with filename NOT in numbering sequence (e.g. foo.jpg, bar.jpg)
- .wav audio
If the audio duration is longer video length, just discard the excessive part of audio at the end.
And all the images have to be shown in same duration.(i.e. The video should be inn/dFPS fornimages and video withdsecond)Since the image input are not in number sequence, I use concat demuxer as input :
let VIDEO_DURATION = 8;
let ffmpeg = await FfmpegUtil.createCommand();
let imageFiles: string[] = ["foo.jpg", "bar.jpg", ...]; //assume there are 67 image files
let demuxerFile = await FfmpegUtil.createConcatDemuxerFile(imageFiles);
let audioFile: string = "path/to/audio.wav";
ffmpeg.input(demuxerFile)
.inputOption(
"-f", "concat",
"-safe", "0",
)
.input(audioFile)
.outputOption(
"-r", `${imageFiles.length}/${VIDEO_DURATION}`,
)
.duration(VIDEO_DURATION)
.save("path/to/output.mp4")
;it will spawn a ffmpeg command :
ffmpeg
-f concat
-safe 0
-i path/to/demuxerFile.txt
-i path/to/audio.wav
-y
-r 67/8
-t 8
path/to/output.mp4However the output file cannot be played.
I also tried
"-framerate", ${imageFiles.length}/${VIDEO_DURATION}in.outputOption(), it still output a file cannot be played and I found the frame rate always be 25 in its file property.Update 1 (added spawned command & ffmpeg console log) :
spawned ffmpeg command & console log (
"-r", `${imageFiles.length}/${VIDEO_DURATION}`asoutputOption) :ffmpeg -f concat -safe 0 -i path/to/demuxerFile.txt -i path/to/audio.wav -y -r 67/8 -t 8 path/to/output_r.mp4
