The pyrowave passthrough rode VAAPI's LINEAR-only modifier policy, which starves it on Mutter+NVIDIA (tiled-only allocations → the compositor declines the offer → CPU capture fallback). The encoder imports through VK_EXT_image_drm_format_modifier, not libva, so the capture now extends the advertisement with every single-memory-plane modifier the PyroWave device samples from (probed via DrmFormatModifierPropertiesListEXT with the same device selection as the encoder). Live on .21 (Mutter+NVIDIA, RTX 5070 Ti): 7 modifiers advertised, the compositor negotiated block-linear (216172782120099861), no CPU downgrade, and the encoder's per-buffer import cache populated exactly as designed (8 PipeWire pool buffers imported once, silent reuse after). Zero-copy session numbers: static 60 fps, e2e 2.9-3.0 ms p50 (p95 3.4), host stage 1.6 ms; full-window motion 60 fps at ~80 Mb/s all-intra, decode ~1 ms. Also neutralizes the VAAPI-specific wording in the passthrough hand-off log. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
