Huawei Freebuds Pro - Linux (KDE Neon) configuration and AAC audio

The default configuration of KDE Neon does not work with the headphones. I have managed to connect them doing some changes, and adjusting some configurations. This resumes that, to keep it if I need to reconfigure them in the future.

This configuration has worked for me using the following setup:

• KDE Neon 5.20, kernel 5.4.0
• Freebuds Pro version 1.9.0.256

An overview of recent action recognition datasets and their detection classes

Concepts & terminologies:

• Action: Atomic low-level movement such as standing up, sitting down, walking, talking etc.
• Activity/event: Higher level occurence then actions such as dining, playing, dancing
• Trimmed video: A short video clip containing event/action/activity of interest
• Untrimmed video: A video clip of arbitrary length potentially containing durations without activities of interest
• Localization: locating an instance of event/action/activity within a video at a spatial or temporal scale
• Spatial localization: Locating the region/area of an instance of action/activity within a video
