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. -

How to detect anamorphic video with FFProbe ?
29 mai 2015, par FlavorScapeThis is the output I get using FFProbe for a video I’m certain is anamorphic. I’ve converted it as a test with ffmpeg and the results are consistent with the video having a different PAR and DAR (video is squished). I ran some command line params to fix anamorphic video and it worked. Possibly my diagnosis is incorrect, the PAR and DAR are just plain wrong ?
The code I used to "correct" the anamamorphic is
--custom-anamorphic --display-width 1280 --keep-display-aspect --modulus 8 --crop 0:0:0:0Is there an additional command with FFProbe to detect for anamorphic ? So far I’m just seeing if the sample_aspect_ratio and display_aspect_ratio are the same or not.
Additionally, a ratio of 0:1 seems incorrect. My video is not infinitely wide. Is there a bug with FFProbe output ?
This is the command

ffmpeg frame rate issue h264+ass to mkv
27 juin 2013, par user2529661I'm using this command for ffmpeg :
ffmpeg -i 1.h264 -i ass1.ass -map 0 -map 1 -c copy test.mkvThe h264 file is 30 fps... the mkv plays at 25fps so it runs slow
The h264 come off my hd webcam. If i change the frame rate on the camera to 25 it works fine and 15fps wilk play at high speed. I can force the frame rate ? Every if i need a different command line tool to change it that is acceptable. But if i could fix it form ffmpeg that would be ideal. I'm running the commands from vb.net.
command output
