Examples

To wechat

• -vf scale=960:-1: scale the resolution to 960*a (a is calculated automatically)
• -b:v: set video bitrate in bps
• -r: framerate in FPS
• -b:a: set audio bitrate in bps

Motivation

The example CMakeLists.txt in PCL’s doc is a bit outdated. Commands like include_directories, link_directories, add_definitions should be replaced or avoid. Instead, in modern CMake we should use target-specific commands like target_include_directories, target_link_libraries.
