On phones and tablets, the app now asks Android for the display's fastest refresh rate (120Hz or 144Hz, for example) each time it comes to the foreground. A WebView never asks for this itself, so many phones were keeping the app at 60Hz.

Frame-rate matching fix: this one is for the player. It only runs during playback when "match frame rate" is turned on, and it picks the refresh rate used while the video plays.

Summary by CodeRabbit

• New Features
  • Non-TV displays can now select the highest supported refresh rate matching the display’s dimensions.
  • On resume, the app checks for the fastest suitable refresh rate. TV displays retain their existing matching behaviour.

Walkthrough

FrameRateMatch now selects display modes with TV-specific behaviour and can prefer the fastest supported mode at the active display dimensions. MainActivity passes the TV-mode value and invokes this method when a started activity resumes.

Changes

Refresh-rate selection

Layer / File(s)	Summary
Refresh-rate mode selection packages/android/app/src/main/kotlin/io/github/viren070/aiostreams/FrameRateMatch.kt	FrameRateMatch accepts a TV flag. For non-TV displays, choose() first searches integer multiples from 1× to 6×. If no mode matches, it uses the existing 1×, 2×, and 2.5× search. TVs use only that existing search. preferFastest() selects the highest-refresh-rate supported mode at the active display dimensions unless the device is a TV or an original preferred mode is saved.
Activity resume integration packages/android/app/src/main/kotlin/io/github/viren070/aiostreams/MainActivity.kt	MainActivity passes its TV-mode value to FrameRateMatch. When a started activity resumes, it resumes the updater and posts a call to preferFastest() on the window decor view.

Merge Risk: Low · previous review 91fd4

Returning to background playback can request a refresh rate that no longer matches the video. This is a narrow, device-dependent playback-quality risk; preserving the active match is a localized fix.

Full details: Title check

Explanation

The title clearly describes the Android frame-rate matching change. It accurately refers to selecting the fastest whole-multiple display mode on phones, although it does not mention the foreground refresh-rate request for phones and tablets.

Full details: Docstring Coverage

Explanation

Docstring coverage is 20.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 5 functions across 2 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

preferFastest() treats original == null as permission to override the window preference, but match() leaves original null when its chosen mode is already active. A resume request may therefore undo a valid playback match.

The activity can request 144 Hz during playback instead of retaining the matched 100 Hz mode.

This can occur when: On a non-TV display supporting 100 and 144 Hz, a 50 fps video is matched while 100 Hz is active; a posted preferFastest() then runs.

Update `match()` so selecting a playback mode already active still records that
mode as the original preference or otherwise prevents `preferFastest()` from
overriding it. Preserve the matched 100 Hz mode when a posted `preferFastest()`
runs during playback, rather than switching to the fastest supported mode.
