Light up the dormant 10-bit/HDR path end to end on the Windows client. - core: NativeClient::connect gains a video_caps param threaded into the Hello. The Windows client advertises VIDEO_CAP_10BIT | VIDEO_CAP_HDR; every other caller (the C ABI shim, Linux, Android, host test connects) passes 0, so the 8-bit BT.709 path is unchanged. The host already gates a Main10/PQ encode on these bits + PUNKTFUNK_10BIT. - video.rs: a PQ frame (color_trc == SMPTE2084) converts 10-bit YUV → X2BGR10 (== DXGI R10G10B10A2) with the BT.2020 matrix via sws_setColorspaceDetails; swscale applies only the matrix + range, so the PQ-encoded samples pass through untouched. - present.rs: on an HDR frame the swapchain flips in place (ResizeBuffers) to R10G10B10A2 + DXGI_COLOR_SPACE_RGB_FULL_G2084_NONE_P2020 + HDR10 metadata; the passthrough shader is unchanged and the compositor maps PQ→display. Switched to ALPHA_MODE_IGNORE so the 10-bit padding bits don't render transparent. SDR stays 8-bit B8G8R8A8. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |

The "broken animations in HDR" was an encode-throughput cliff, not the ACCESS_LOST churn. Measured at 5120x1440@240 HEVC Main10 on the RTX 4090: forced 2-way split-encode = 7.6 ms/frame (~131 fps, well over the 4.17 ms/240fps budget → choppy), while SINGLE engine = 2.8-3.9 ms/frame (~256-357 fps, fits 240). The split/merge overhead dominates for 10-bit; a single Ada NVENC engine already handles 5K@240 Main10 comfortably. So the split decision now forces DISABLE for Main10 (bit_depth >= 10), keeping the existing forced-2 only for 8-bit above 1 Gpix/s. PUNKTFUNK_SPLIT_ENCODE still overrides. Added a split-mode log line. Validated live on the 4090: encode_us_p50 7.6 ms → 3.9 ms at 5K240 HDR with no env override. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |
