Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

Is Electron using a custom-licensed libx264 variant ?
13 septembre 2016, par JohnWElectron is providing a few variants of FFmpeg.
The variant I have seems to handle H264 just fine, which it does using libx264 apparently.
The question is simple : Do electron developers have a special deal with VideoLan to provide an MIT licensed FFmpeg with x264 ?
I am asking because VideoLan seems to dual-license libx264 (GPL and custom license) so it is possible that there is a deal.
According to this link however the answer may very well be "no".

Layer black & white video over background so black pixels are transparent in FFMPEG
4 février 2018, par Dan WeaverI’m trying to blend a video containing black and white animated text over a static background image. I can successfully blend them but no matter what blend mode I use I can’t get the effect I want.
I’m looking for an effect similar to Photoshop’s ’Add’ blend mode where the color values of each pixel are added together. This results in no change where the top layer (video) has black pixels, effectively making the black background appear transparent.
This is what I’m trying to achieve :
ffmpeg -i text.mp4 -loop 1 -i image.jpg \
-filter_complex 'blend=all_mode=addition' -t 1 result.mp4I tried all the modes of the
blend
filter but none of them produce this effect. I thought Addition would be the one to work but the resulting video has a pink tint. Maybe there is some mismatch between color channels ?How can I get the result I’m looking for ?
