• You need to go to https://ffmpeg.org/download.html to download the latest version of ffmpeg's shared libraries (the current version of ffmpeg is 4.4). Extract it to /L7Player/external_dependencies/ directory and rename it to ffmpeg.

• You have to create before running the test case /L7Player/resource/media directory and prepare test.mp4 file.

The dir is:

L7Player
----bin
----external_dependencies
--------ffmpeg # download and extract by yourself
--------glad
--------glfw
--------glog
--------googletest
--------sdl
----inc
----lib
----multimedia
----resource
--------media
------------test.mp4 # prepare by yourself
