Finding which process to profile

If your system is running slowly, perhaps a process is using too much CPU time and won't let other processes run smoothly. To find out which processes are taking up a lot of CPU time, you can use Apple's Activity Monitor.

Installing Arch Linux on VirtualBox in Windows 10

I recently upgraded to a new system, and instead of running Arch Linux natively I've decided to run it inside VirtualBox on Windows 10.

Old solutions

Vitamio.https://github.com/yixia/Vitamio-iOS
Result: random crashes and not working cameras
https://github.com/kolyvan/kxmovie
Result: compile time error. I haven't successfully integrated it to my project.
GStreamer. https://github.com/sdroege/gst-player

These links no longer work. Springer have pulled the free plug.
