Bounty

Whoever fully implements MediaElement parity for this repository will receive a lifetime commercial license for InkkSlinger.

Objective

Implement a usable MediaElement control aligned with this project's WPF-parity target and architecture.

Scope

• Add MediaElement control type with core playback surface and lifecycle semantics appropriate for this framework.
• Integrate with layout/render/invalidation and input/event systems as needed.
• Expose XML/XAML parser + schema authoring support where applicable.
• Add focused tests and a minimal validation/demo surface if needed.

Acceptance Criteria

• Clean build: dotnet build InkkSlinger.sln -c Release -v minimal
• New deterministic tests in InkkSlinger.Tests/ for implemented playback/state behavior.
• Full test project remains green: dotnet test InkkSlinger.Tests/InkkSlinger.Tests.csproj -c Release -v minimal
• TODO.md, README.md, and UI-FOLDER-MAP.md updated for coverage/status changes.

Important: Media Decoding Strategy Must Be Agreed Before Implementation

This control is fundamentally a media pipeline integration problem, not just a control wrapper. Unlike the other bounty items, MediaElement requires audio/video decoding — there are no existing hooks in the codebase for this. On DesktopGL this will almost certainly require a third-party library dependency (e.g. an FFmpeg wrapper).

Before starting significant implementation work, open a discussion or comment on this issue to propose your decoding approach and dependency choice. The maintainer must approve the strategy upfront to avoid a rejection at PR review time on architectural or dependency grounds.

Notes

• Keep PR focused on MediaElement parity work and tests.
• Any platform constraints/limitations must be explicitly documented in the PR.
• Final reward determination is maintainer-approved based on merged implementation quality/completeness.
