Support de tous types de médias

10 avril 2011

Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)
Ajouter notes et légendes aux images

7 février 2011, par kent1

Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

Python Subprocess with ffmpeg & django file (video) object thumbnail generation error

12 juin 2018, par denbot
I am trying to re-write the currently outdated easy-thumbnails-ffmpeg and have made some progress. However, I am currently getting the error "no such file or directory" when attempting to send a stream of bytes (mp4 video) into ffmpeg, a frame at 00:01 to an image and output it as a stream of bytes.
```
from PIL import Image

from subprocess import Popen, PIPE

from django.utils.six import BytesIO



def ffmpeg_frame(source, frame='00:00:01', **options):



    if not source or not source._file:

        return



    source._file.seek(0)

    cmd = ['ffmpeg','-i','-f','h264','-','-ss',frame,'-vframes','1','-f','image2' ,'-']

    data = Popen(cmd, stdin=PIPE, stdout=PIPE, stderr=PIPE).communicate(source.read())



    print('Output:', data)



    if not data[0]:

        return



    image = Image.open(BytesIO(data[0]))

    image.load()



    return image
```
I’m unsure if the issue is to do with my use of ffmpeg flags or how I am piping in/out byte data.

When placing the flags ’-f’,’h264’ before ’-i’, I also get the following error : Error while opening decoder for input stream #0:0 : Invalid data found when processing input

Removing the -f h264 flag gives the following error :
annot determine format of input stream 0:0 after EOF\nError marking filters as finished\nConversion failed !

Error : mingw32/bin/ld.exe : cannot find -lavformat when compiling goav

18 avril 2018, par nevernew

I’m trying to compile goav on Windows and I’ve got quite far I’ve compiled the ffmpeg libraries in MSYS2 and linked the packages with :

set CGO_CFLAGS=-IC:\path\to\FFmpeg\

set PKG_CONFIG_PATH=%~dp0FFmpeg\libavformat;%~dp0FFmpeg\libavcodec;%~dp0FFmpeg\libavutil;%~dp0FFmpeg\libswresample;

which has worked !

However, I’m now getting the error could not determine kind of name for ...

A Fix

I added the sub folders of FFmpeg to LDFLAGS and it’s not getting errors for those libraries anymore.

@set CGO_LDFLAGS=-L%~dp0FFmpeg\ -L%~dp0FFmpeg\libavformat -L%~dp0FFmpeg\libavcodec -L%~dp0FFmpeg\libavutil -L%~dp0FFmpeg\libswresample

I also found GNUWindows ports for zlib and bzip2, so their errors have disappeared.

But I’m still getting errors for -lbcrypt. anyone know where/how to go about getting this lib ?
