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. -

Remapping multiple Mp4 videos into a single one with ffmpeg
21 septembre 2016, par Josep BoschI’m interested in remapping multiple (6) MP4 videos into a high resolution final video according to lookup tables I calculated. The idea is convert 6 independent videos in a 360º video according to an equirectangular projection.
Example of equirectangular video hereIs there a way to do this remapping with ffmpeg or any other linux program ?
Right now I’m extracting all the frames from the videos, creating the equirectangular individual images and joining them again into a video. There must be a better way for this...UPDATE :
Following Mulyva’s suggestion I first remap each individual video using the remap filter. Those parts of the panoramic video not covered are interpreted like chromakey pixels using :
ffmpeg -i videos/camera1.MP4 -i camera0_map_x_radius5.pgm -i camera0_map_y_radius5.pgm -lavfi remap -qscale 1 out0.MP4
Then I try to overlay them using the chomakey filter :
ffmpeg -i out0.MP4 -i out1.MP4 -filter_complex "[1:v]chromakey=0x12da11:0.2:0.2[chromakey_res];[0:v][chromakey_res]overlay=eof_action=pass[out]" -map "[out]" out.mp4
As you can see, the final result has an undesirable green shadow. Any idea of how to remove it ?

Ffmpeg one image video convert faster
27 août 2015, par user997841At the moment I can convert a video with one image and an mp3. I was wondering how I can make the converting faster, because it takes 5min to render one image and place an mp3 of 3min.
ffmpeg -y -loop 1 -i image.jpg -i track.mp3 -c:v libx264 -tune stillimage -c:a aac -strict experimental -b:a 192k -pix_fmt yuv420p -shortest final.mp4
Thx !
