GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

1. Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
2. Create or import a key -- see below for https://keybase.io
3. Run gpg --list-secret-keys and look for sec, use the key ID for the next step
4. Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

I have tried a lot of solutions for IP-camera streams.

Old solutions

1. Vitamio.https://github.com/yixia/Vitamio-iOS
   Result: random crashes and not working cameras

2. https://github.com/kolyvan/kxmovie
   Result: compile time error. I haven't successfully integrated it to my project.

3. GStreamer. https://github.com/sdroege/gst-player

// I just implemented that with Swift. So I would like to share my implementation.
