  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.

  • How to insert emote-like images among text with ffmpeg ?

    26 janvier 2020, par Vijay Bharadwaj

    I am using FFMPEG to recreate a twitch-like video chat for streaming overlay and wanted a way to insert twitch emotes into the chat that I have. The twitch emotes come in small png/jpg files.

    Currently, I use the drawtext command on several messages to get the text part of the chat, but the emotes are integral to make it look like twitch chat. Any idea how to do this ?

    If it helps, I have a working simulation of the twitch chat on a video in a webpage, using HTML, CSS, and javascript. All I’m trying to do is take what’s simulated and embed it into the video.
