This code is a UserScript designed to be used with browser extensions like Tampermonkey or Greasemonkey. Here's a breakdown of what it does:
High-Level Function:
The script is intended to optimize video playback on the kaa.to
website by dynamically adjusting playback speeds (6x–14x) based on the state of the video player's buffer, using a "quantum stabilization" mechanism. It attempts to ensure smooth playback by monitoring and responding to buffer levels in real time.
Detailed Breakdown:
Metadata:
@name
and@description
: The script's name is "Kaa.to Quantum Stabilizer 6x-14x". Its purpose is described as adaptive buffer-tier acceleration with "quantum response".@match
: The script is only executed on URLs matching*.kaa.to/*
.@require
: jQuery 3.6.0 is included as an external dependency.@run-at
: The script executes at thedocument-start
, meaning it activates as soon as the page begins loading.
Core Functionality:
-
Acceleration Tiers:
- The script defines several tiers of acceleration with different multipliers (6x to 14x), buffer thresholds, cooldown periods, and stabilization factors.
- These tiers represent possible playback speeds the video player can switch to, aiming for smooth operation under varying conditions.
-
QuantumBufferTracker
Class:- This class tracks buffer dynamics and determines the current buffer health of the video player(s).
- It continuously analyzes:
- Overall and minimum buffer levels.
- Trends in buffer level changes (whether the buffer is "rising" or "falling").
- Based on the collected metrics, it calculates the optimal acceleration tier for smooth playback.
-
QuantumAccelerator
Class:- This class handles the core logic for adapting the playback speed based on buffer health.
- Key Steps:
- Detect video players on the page (
detectPlayers()
). - Periodically analyze buffer dynamics and determine the appropriate playback tier (
quantumAdaptationCycle()
). - If necessary, prepare a transition to a new tier (
executeTierTransition()
). - Stabilize playback speed by applying a fine-tuned playback rate (
applyStabilizedSpeed()
).
- Detect video players on the page (
- It makes use of a
setInterval
loop (running every 250ms) to continuously monitor and adapt playback behavior.
-
Interaction With Video Players:
- The script leverages a hypothetical
quantumAPI
on video elements to interact with the buffering and playback speed of each video. - Functions such as
getBufferHealth()
,smoothTransition()
, andsetPlaybackRate()
are used to read buffer data, enable smooth speed transitions, and adjust playback rates.
- The script leverages a hypothetical
-
Event Listeners:
- The script listens for
DOMContentLoaded
to start the adaptation process (initiateQuantumAcceleration()
). - A
beforeunload
listener ensures the cleanup of thesetInterval
loop when the user leaves the page.
- The script listens for
Purpose/Outcome:
-
Adaptive Playback Optimization:
- The script continuously monitors buffer health and dynamically adjusts playback speed to maintain smooth playback at high acceleration tiers (up to 14x speed).
- It reacts to small buffer changes and minimizes playback interruptions by adjusting both speed and transition durations.
-
Intelligent Stabilization:
- Stabilization factors and trends ("rising" or "falling" buffers) affect how aggressively or cautiously the script adjusts playback rates.
-
Real-Time Adaptation:
- Frequent updates (every 250ms) ensure that the script responds quickly to changing conditions, such as network fluctuations affecting the buffer.
Conclusion:
This script is intended for advanced control of video playback on the kaa.to
website. It dynamically adjusts playback speeds using buffer-aware logic, ensuring smooth and efficient operation even at very high speeds (6x–14x).
