Le plugin : Podcasts.
14 juillet 2010, parLe problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;

Anomalie #3607 : Problème de compatibilité avec mysql 5.7 pour SPIP 3.1
26 avril 2016, par Guillaume FahrnerLe format est correct, la valeur ne convient par contre pas. La changer parait suffisant :
https://github.com/concrete5/concrete5/issues/3185 :
The DATETIME type is used for values that contain both date and time parts. MySQL retrieves and displays DATETIME values in ’YYYY-MM-DD HH:MM:SS’ format. The supported range is ’1000-01-01 00:00:00’ to ’9999-12-31 23:59:59’.

ffmpeg - scaling and stacking 2 videos ?
25 mai 2016, par Gambit2007I have 2 inputs and i want to scale, crop and put them on top of each other at the same time. My command should look something like this :
ffmpeg -i input1 -i input2 -filter_complex crop=10000:5000:1000:0,scale=3840:1536 vstack output.mp4
I know i need to use chaining (?) but i tried to look it up online and couldn’t really get it to work.
So what would be the correct syntax the scale and crop both inputs and then put them vertically on top of each other while using ’-filter_complex’ only once ?
Thanks !

.mov
to.mp4
the conversion halts at 98%.Almost all of our other preferred formats encode flawlessly. Anyone has any clue on where we went wrong ? We are struggling on this for a while now so we want to ask the experts, thanks in advance for any help.
