Plugin Requirements

Some SocialEngine plugins have optional requirements:

Chat Plugin

VPS or dedicated server - budget/shared servers may not handle a high volume of users chatting at the same time.

Video Plugin

  • FFmpeg (for encoding video; click here to read more on how to set it up correctly) - without ffmpeg, users can still post YouTube and Vimeo videos.
  • allow_url_fopen enabled for video sharing from sites such as YouTube, Vimeo, etc. Note that shared hosting may not allow this and you would want to seek other hosting options.
