Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...) -
Emballe médias : à quoi cela sert ?
4 février 2011, parCe plugin vise à gérer des sites de mise en ligne de documents de tous types.
Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ; -
Menus personnalisés
14 novembre 2010, parMediaSPIP utilise le plugin Menus pour gérer plusieurs menus configurables pour la navigation.
Cela permet de laisser aux administrateurs de canaux la possibilité de configurer finement ces menus.
Menus créés à l’initialisation du site
Par défaut trois menus sont créés automatiquement à l’initialisation du site : Le menu principal ; Identifiant : barrenav ; Ce menu s’insère en général en haut de la page après le bloc d’entête, son identifiant le rend compatible avec les squelettes basés sur Zpip ; (...)

Youtube DL Unable to get local issuer certificate - CERTIFICATE_VERIFY_FAILED
24 novembre 2022, par Casper KristianssonI'm trying to use youtube DL with FFmpeg to download an m3u8 stream. Just recently I started receiving this error :


ERROR: Unable to download webpage: <urlopen error="error" verify="verify" unable="unable" to="to" get="get" local="local" issuer="issuer" certificate="certificate">
(caused by URLError(SSLCertVerificationError(1,
'[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed:
unable to get local issuer certificate (_ssl.c:992)')))
</urlopen>

I know Youtube DL supports an option for nocheckcertificate but by enabling this after a couple of minutes the target machine will refuse the connection. When trying to use the same m3u8 stream on another computer, I could download the stream without any issues.


I know that someone from Youtubedl CERTIFICATE_VERIFY_FAILED suggested fixing "your system's CA certificate list". What is the process of doing this ?


I tried upgrading/reinstalling python and reinstalling the latest Windows update


I also want to mention that there hasn't been any issue with downloading for the past year but recently stumbled upon this when switching proxy providers. But because the same setup works on another PC without any issue it's probably not the reason.


The system the program is running on is Windows


Edit : Another note is that downloading other public m3u8 streams works perfectly fine, so the problem is probably with the system CA SSL.

Pygame : Frame ghosting ?
5 octobre 2022, par Sam TubbI am working on a animation environment in python using pygame. The user draw's each frame, and then using ffmpeg the animation is saved as an .avi movie. I would like to implement a feature, but am not sure how.. frame ghosting. Like display the previous frame while you draw the current.



I tried creating a surface called
ghostthat copies the current frame when the next-frame key is pressed. Then draws it with an alpha level of 10, but this didn't work out correctly.


I am not sure what to do, here is the source code for anyone that thinks they have an idea :

 if pygame.mouse.get_pressed() == (1, 0, 0):
 pygame.draw.line(draw, color, lineStart, lineEnd, size)
 lineStart = lineEnd

 pygame.display.flip()



Oh, and on another note, just if anyone was curious, here is what the output looks like.. I made a little new year's animation :

Issues with using FFmpeg to generate MPEG-DASH files
26 septembre 2022, par Tina JI am using the following
ffmpegcommand to generate MPEG DASH files and manifest. I usesingle_file 1to have a single file for each representation ; so no chunking. But IDK why when I want to play the manifest using ExoPlayer, the video doesn't play from the beginning (rather it starts from around 50s).

ffmpeg -re -i .\video-h264.mkv -map 0 -map 0 -c:a aac -c:v libx264 -b:v:0 800k -b:v:1 300k -s:v:1 320x170 -profile:v:1 baseline -profile:v:0 main -bf 1 -keyint_min 120 -g 120 -sc_threshold 0 -b_strategy 0 -ar:a:1 22050 -use_timeline 1 -single_file 1 -use_template 1 -window_size 5 -adaptation_sets "id=0,streams=v id=1,streams=a" -f dash out.mpd


What is wrong with this ? Is the manifest correct ? Here is the generated mpd :
