Thriving 
SW Media player engine for iOS, tvOS, macOS and visionOS. FFmpeg demux, VideoToolbox / dav1d / libavcodec decode (HEVC, H.264, AV1, VP9, MPEG-2, VC-1), live TV with DVR timeshift and hardware deinterlace, Dolby Atmos passthrough, HDR10 / HDR10+ / Dolby Vision / HLG, text + bitmap + teletext subtitles, plus a lean audio-only path. You ship the UI.

A media player engine for Apple platforms.
FFmpeg demuxes. VideoToolbox decodes. AVPlayer handles Dolby Atmos.
Video, live TV with DVR timeshift, or a lean audio-only path with system Now-Playing. You ship the UI.
A player engine that gets the hard parts right (HDR, Dolby Vision, Dolby Atmos, container coverage, codec coverage) and exposes a single AetherPlayerView (UIKit / AppKit) or AetherPlayerSurface (SwiftUI) plus a handful of async methods. No AVPlayerViewController. No opinionated controls. No analytics. Bind the view, call play(), read the published properties for state.
The view is polymorphic: under the hood the engine swaps the hosted CALayer (AVPlayerLayer for the native AVPlayer path, AVSampleBufferDisplayLayer for the SW dav1d fallback path) per session without the host having to know.
You provide the transport bar. You provide the dropdowns. You provide the pretty.
How much a project earns versus how much attention it actually gets. Above 50 means the work is outrunning its audience. Recomputed nightly from commit velocity, contributor effort, issue resolution, fork utility, release cadence, and project maturity — divided by a logarithmic reach factor.
score = signal / reach
signal = 0.25·commit_velocity // commits in last 90 days (cap 30)
+ 0.20·contributor_work // unique authors × velocity (cap 100)
+ 0.20·issue_resolution // closed ÷ total issues
+ 0.20·fork_ratio // forks ÷ stars (proxy for real usage)
+ 0.10·release_cadence // releases in 90 days (cap 3)
+ age_bonus // +0 to +0.30 after 6 months
+ homepage_bonus // +0.05 if homepage is set
reach = log₁₀(stars + watchers + 10)█ Is the project alive and maintained right now? A 0–100 pulse recomputed nightly from commit recency, rhythm, how fast issues close, and how quickly PRs get merged.
health = 0.35·recency // days since last commit (90d decay)
+ 0.25·cadence // commit rhythm consistency
+ 0.20·issue_health // closed ÷ total issues
+ 0.20·pr_health // merged ÷ total PRs█ The colour and label on every card come straight from the health score.
Healthy 80 – 100 active, responsive, regular releases
Stable 60 – 79 maintained, steady, no alarms
Quiet 40 – 59 slowing down — watch this one
At Risk 0 – 39 going dark · candidate for rescue█ Tags are independent behavioral signals computed nightly. A project can hold multiple at once. They drive the home page sections.

funded maintainer has active funding channel█ Stars are an outcome, not effort. A project with 8 stars and daily commits is doing more interesting work than one coasting on 8k. We measure the building, then divide by the attention already received — so the genuinely undervalued rise to the top.
