Project Memory — screen_cast

Last updated: initial scaffold.

Project state

• Phase 1 complete: Meson build, C++20 module headers, agent workflow, clock utility, and a passing unit test.
• Active phase is now Phase 2 (software H.264 encode/decode).
• No implementation yet for capture/codec/network/render.

Decisions

• Language: C++20 with explicit modern-C++ guidelines in AGENTS.md and cpp-meson-build/SKILL.md.
• Build system: Meson.
• Capture: PipeWire + xdg-desktop-portal.
• Encode/Decode: FFmpeg (libavcodec, libavutil, libswscale).
• Transport: RTP over UDP; signaling via WebSocket/JSON.
• Discovery: mDNS/Avahi.
• Rendering: SDL2 or SDL3 + OpenGL.
• Namespace: sc.

Active blockers

None.

Open questions

• GUI framework (Qt6 vs. none / CLI only) — deferred to later phase.
• Hardware acceleration strategy (VAAPI / Vulkan Video / NVENC) — evaluate after software encode path works.
