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/ffplay stream error using Windows 10
23 juin 2018, par AlanI’m using Android’s screenrecord to stream the device screen via adb and pipe the
output to ffplay 3.4. It works great using OS X via the command :adb shell screenecord --bit-rate=16m --output-format=h264 --size 800x600 - | c:\bin\ffplay.exe -framerate 30 -framedrop -bufsize 60M -
Windows 10 is a different story. I get a blurred out screen and the following stream of errors :

ffpmeg drops last frame when compressing from MP4 to MP4 (libx264)
28 octobre 2018, par UsoboiSo, I’m using this code to compress my *mp4 file. I need to get lower quality and decrease bitrate :
ffmpeg -i input.mp4 -c:v libx264 output.mp4
The problem is : the last frame of footage is dropped after ffmpeg compression.
Screenshot is here : screenshot_ffmpeg_drop frameI tried to use full preferences I need, but the problem is the same.
