streaming-media-architecture

streaming-media-architecture is a skill for Claude Code, Codex from sunnat629/android-media-pack. It costs 40 tokens per session (1,136 once invoked), scanned A, original, Apache-2.0.

A guide for structuring production Android and Kotlin Multiplatform video apps with Media3, Android's media playback library. It covers player ownership, shared playback state, preloading, offline data, short-video feeds, and measurement.

In plain words
What is it for?
Use it as the starting point for Media3 architecture, reels and short-video feeds, Kotlin Multiplatform boundaries, playback ownership, preloading, and production readiness.
Why use it?
It prevents common architecture problems such as creating a player for every feed item, letting the interface call the network directly, or loading too much video for the device's battery, memory, or connection.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

streaming-media-architecture scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Trigger

Use first for Media3 architecture, reels/short-video feeds, KMP split decisions, player ownership, preloading, and production streaming readiness.

Rules

  • Baseline: Media3 1.10.1; use version catalog, no hardcoded Gradle versions.
  • KMP/common: domain models, repositories, playback policy, feed ranking, state, events, analytics contracts.
  • Android source set: ExoPlayer, MediaSessionService, MediaController, Media3 UI, DataSource, cache, DRM.
  • UI is UDF: immutable state down, events up. Repositories own truth; UI never calls network directly.
  • One playback owner per screen/session. Do not create/release a player per feed row.
  • Short feed uses bounded sliding window. Preload next/prev only; respect data saver, battery, thermal, memory.
  • Telemetry comes from AnalyticsListener, PlaybackStatsListener, player callbacks, and measured UI handoff points.

Short-Video Feed Pattern

  • A playback service or screen-scoped owner manages one Android ExoPlayer and optional MediaSession.
  • Common/KMP-safe controller APIs build a video-only media queue from feed items.
  • Active page is guarded by stable media identity; database id is best, URI is acceptable fallback.
  • State contract includes mediaUri and renderedMediaUri.
  • Compose attaches the player surface as soon as the active item owns the player.
  • Keep thumbnail above the player until onRenderedFirstFrame reports the same media identity.
  • Remove thumbnail only when activeItem == mediaUri == renderedMediaUri.
  • Keep ContentFrame/player surface in the composition. If it is hidden until ready, first-frame callback may never arrive.
  • Inline scrollers can use TextureView for overlay/thumbnail handoff. Prefer SurfaceView for stable fullscreen/HDR surfaces.
  • Use setPauseAtEndOfMediaItems(true) so pager navigation controls item advance.
  • Use small ExoPlayer.PreloadConfiguration, then graduate to DefaultPreloadManager when queue/window telemetry proves it is needed.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
