How to Add a Watermark to Video

FFMPEG filters provide a powerful way to programmatically enhance or alter videos, and it’s fairly simple to add a watermark to a video using the overlay filter. The easiest way to install ffmpeg is to download a pre-built binary for your specific platform. Then you don’t have to worry about including and installing all the right dependencies and codecs you will be using.

Once you have ffmpeg installed, adding a watermark is as easy as passing your existing source through an overlay filter like so:

ffmpeg -i test.mp4 -i watermark.png -filter_complex "overlay=10:10" test1.mp4

Basically, we’re passing in the original video, and an overlay image as inputs, then passing it through the filter, and saving the output as test1.mp4.

Third Party Authentication Features in Open edX: Technical Knowledge Transfer

Part 1: Background / Notes

• Open edX has full, integrated support for three different types of third party auth provider:
  1. OAuth based providers (OAuth2 and the older OAuth v1). Google, Facebook, LinkedIn, and Azure Active Directory are available by default. Any other OAuth backends supported by python-social-auth v0.2.12 can be enabled by changing a configuration setting. Contributed by Google (John Cox).
  2. SAML / Shibboleth. SAML is an SSO standard mostly used by universities and corporations. Shibboleth is the name of a particular implementation of SAML, commonly used by higher ed. institutions.
  3. LTI. Users can use Learning Tools Interoperability® (LTI®) to authenticate. Support for this was contributed by UBC.
• The Open edX platform also includes limited support for the following SSO providers.

1. Take a backup of docker.service file.
   $ cp /lib/systemd/system/docker.service /lib/systemd/system/docker.service.orig

2. Modify /lib/systemd/system/docker.service to tell docker to use our own directory 
   instead of default /var/lib/docker. In this example, I am using /p/var/lib/docker
   
   Apply below patch.

   $ diff -uP -N /lib/systemd/system/docker.service.orig /lib/systemd/system/docker.service
