Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

ffmpeg isn't accepting "%d" format ?
7 janvier 2017, par Tim WescottSo, I have a directory full of files named
motor_animate_000.gif,motor_animate_001.gif, etc.I run :
ffmpeg -r 30 -i motor_animate_%03d.gif -r 30 motor.mpgI expect to get a file called
motor.mpg, but instead I get the usual bunch of printout, ending with :motor_animate_%03d.gif: No such file or directoryWhat ? This worked in Ubuntu 14.04, but doesn’t work now. What I’m doing appears to be consistent with the ffmpeg man page. I’m now officially clueless. Thanks in advance.
Here’s what I get when I try the alternate suggested below :
tim@Servo:~/Documents/Movies/dcmotor/animation$ ffmpeg -f image2 -framerate 30 -i motor_animate_%03d.gif motor.mpg

How to add a Poster Frame to an MP4 video by timecode ?
25 mai 2020, par CrissovThe
mvhdatom or box of the original Quicktime MOV format supports aposter timevariable for a timecode to use as a poster frame that can be used in preview scenarios as a thumbnail image or cover picture. As far as I can tell, the ISOBMFF-based MP4 format (.m4v) has inherited this feature, but I cannot find a way to set it using FFmpeg or MP4box or similar cross-platform CLI software. Edit : Actually, neither ISOBMFF nor MP4 imports this feature from MOV. Is there any other way to achieve this, e.g. using something like HEIFʼs derived images with athmb(see Amendment 2) role ?





The original Apple Quicktime (Pro) editor did have a menu option for doing just that. (Apple Compressor and Photos could do it, too).






To be clear, I do not want to attach a separate image file, which could possibly be a screenshot grabbed from a movie still, as a separate track to the multimedia container. I know how to do that :



- 

- Stackoverflow #54717175
- Superuser #597945







I also know that some people used to copy the designated poster frame from its original position to the very first frame, but many automatically generated previews use a later time index, e.g. from 10 seconds, 30 seconds, 10% or 50% into the video stream.
