Other interesting software
13 avril 2011, parWe 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.

Configuration spécifique d’Apache
4 février 2011, parModules spécifiques
Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

Adding a custom filter to FFmpeg
16 juillet 2024, par AbhimanyuI am looking to configure and compile FFmpeg with custom filter.
custom filters are available on this git repository which is compiled with older ffmpeg version
https://github.com/numberwolf/FFmpeg-PlusPlus


I am following the steps mentioned on the ffmpeg official website
https://github.com/FFmpeg/FFmpeg/blob/master/doc/writing_filters.txt


I am getting warning plusglshader filter is unknown and same for all other filters


Here are my steps :


First, create your filter source files in the libavfilter directory :


`libavfilter/vf_plusglshader.c
libavfilter/vf_pipglshader.c
libavfilter/vf_lutglshader.c
libavfilter/vf_fadeglshader.c`



Update the FFmpeg build system by adding your new filter files to libavfilter/Makefile :


I am getting following below steps


First, create your filter source files in the libavfilter directory :


`libavfilter/vf_plusglshader.c
libavfilter/vf_pipglshader.c
libavfilter/vf_lutglshader.c
libavfilter/vf_fadeglshader.c`



Update the FFmpeg build system by adding your new filter files to libavfilter/Makefile :


`OBJS-$(CONFIG_PLUSGLSHADER_FILTER) += vf_plusglshader.o
OBJS-$(CONFIG_PIPGLSHADER_FILTER) += vf_pipglshader.o
OBJS-$(CONFIG_LUTGLSHADER_FILTER) += vf_lutglshader.o
OBJS-$(CONFIG_FADEGLSHADER_FILTER) += vf_fadeglshader.o`



In libavfilter/allfilters.c, add your filter declarations :


`extern const AVFilter ff_vf_plusglshader;
extern const AVFilter ff_vf_pipglshader;
extern const AVFilter ff_vf_lutglshader;
extern const AVFilter ff_vf_fadeglshader;`



In libavfilter/filter_list.c (not allfilters.c), add your filters to the filter_list array :


`static const AVFilter * const filter_list[] = {
 // ... existing filters ...
 &ff_vf_plusglshader,
 &ff_vf_pipglshader,
 &ff_vf_lutglshader,
 &ff_vf_fadeglshader,
 NULL
};`



In libavfilter/allfilters.c, add your filter declarations :


`extern const AVFilter ff_vf_plusglshader;
extern const AVFilter ff_vf_pipglshader;
extern const AVFilter ff_vf_lutglshader;
extern const AVFilter ff_vf_fadeglshader;`



In libavfilter/filter_list.c (not allfilters.c), add your filters to the filter_list array :


`static const AVFilter * const filter_list[] = {
 // ... existing filters ...
 &ff_vf_plusglshader,
 &ff_vf_pipglshader,
 &ff_vf_lutglshader,
 &ff_vf_fadeglshader,
 NULL
};`

Is there a way to use ffmpeg to determine the encoding of a file before transcoding ?
8 février 2016, par Bill NobleI am planning to use ffmpeg to ensure all video files uploaded to my website are encoded as mp4 h264.
Rather than automatically processing every file I would like to minimise the processing overhead by only processing those files that are not already mp4 h264. Is there an easy way to do this either with ffmpeg or with another command line utility ?
