Install
Detailed instructions for building libopenshot and libopenshot-audio for each OS. These instructions
are also available in the /docs/ source folder.
Hardware Acceleration

decoding videos. When enabled, this can either speed up those operations or slow
them down, depending on the power and features supported by your graphics card.
Please see doc/HW-ACCELL.md for more information.
