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 (...)

Trouble with the ffmpeg -ss flag when capturing one frame from a Macbook iSight webcam
1er mars 2014, par AndyFor about five years I've used ffmpeg in a shell script to grab one frame from my linux'd-up Macbook's iSight :
ffmpeg -f video4linux2 -s 640x480 -r 15 -i /dev/video0 -an -vframes 1 -vcodec mjpeg -y -sameq -ss 1.5 snapshot.jpg
I just upgraded my Ubuntu distro from Lucid to Natty (ffmpeg ver. 0.6.2-4:0.6.2-1ubuntu1).
Now that syntax turns the iSight on but hangs indefinitely.[output snipped, ending with:]
frame= 0 fps= 0 q=0.0 Lsize= -0kB time=10000000000.00 bitrate= -0.0kbits/s
video:0kB audio:0kB global headers:0kB muxing overhead -inf%Without the '-ss' flag it seems to successfully grab the first frame and exit immediately - the only difference in output being :
frame= 1 fps= 0 q=0.0 Lsize= -0kB time=0.07 bitrate= -2.6kbits/s
video:16kB audio:0kB global headers:0kB muxing overhead -100.132730%However, the '-ss 1.5' was necessary to delay the frame capture by 1.5 seconds to allow the cam sufficient time to adjust the exposure.
The -itsoffset flag seemed promising, but doesn't seem to change ffmpeg's behavior (ie doesn't hang, but no delay).
Any ideas ?

Revision f872a98b1b : Adds speed 8 to vp9 as reference Adds a speed 8 to VP9 where only the nearestmv

Adds speed 8 to vp9 as referenceAdds a speed 8 to VP9 where only the nearestmv (0 mv) is searched.
This seems to be about the same speed as vp8 speed 5.Adds a new speed feature to disable inter modes based on a mask for
each blocksize.Adds code for having lower complexity motion search methods
in nonrd pick mode function, even though speed 7 still uses DIAMOND
search for now.Also uses HEX search for speed 6 rather than FAST_HEX which improves
psnr by 0.56% without any noticeable speed drop (tested on gipsmotion).Change-Id : Ic13176572dbd3aed5884a26786940a4b1bbd8a75

Modify /vp9/encoder/vp9_rdopt.c
cost_coefs approximation speed upThis patch adds a new speed feature which doesn't do the rather
expensive entropy context lookup or save to the table, while
doing costing.The speed up on desktop36p.y4m is around 10% other clips much less.
On the RTC test set this was + 1% in overall datarate.
