H264QpelContext.put_h264_qpel_pixels_tab[1][2] (8x8 luma horizontal half-pel, 6-tap "put" — the canonical representative of the H.264 luma motion-compensation family) now dispatches through daedalus_recipe_dispatch_h264_qpel_mc20 instead of ff_put_h264_qpel8_mc20_neon. Cycle 9 of the daedalus-v4l2#11 step 2 substitution arc; closes the 4-cycle libavcodec.so substitution sequence: cycle 6 (PR #76) H.264 IDCT 4x4 done cycle 7 (PR #85) H.264 IDCT 8x8 done cycle 8 (PR #86) H.264 luma-v deblock done cycle 9 (this) H.264 qpel mc20 Bumps daedalus-fourier pin d87239d → 209a421 (PR #2 — public API gains daedalus_recipe_dispatch_h264_qpel_mc20 + DAEDALUS_KERNEL_H264_QPEL_MC20). Verdict per docs/k9_h264qpel_mc20.md: CPU NEON. Per-block 7.6 ns at 131 Mblock/s gives 135× margin over 30 fps 1080p; QPU dispatch floor at ~250 ns makes any V3D shader strictly worse. Substitution is plumbing-only — same daedalus_ctx_create_no_qpu pthread_once shape the cycles 6/7/8 shims already own (kept SEPARATE from the H264DSP shim's ctx because H264QPEL is its own libavcodec Makefile module and link order does not guarantee a single .o owns the ctx symbol; one extra ~µs init per process, paid lazily on first MC call). Other H.264 luma MC variants (mc02, mc11, mc22 etc.) and the 16x16 size tier stay on the in-tree NEON .S code per the cycle-9 phase-1 rationale (mc20 8x8 is representative; remaining variants would multiply recipe-lookup overhead without changing the substrate verdict). Bit-exact against ff_put_h264_qpel8_mc20_neon (daedalus-fourier cycle 9 green; 10000/10000 random blocks bit-exact, M3 = 131 Mblock/s). No SONAME change, no Depends change. PKGREL 9 → 10. Refs reauktion/daedalus-v4l2#11 — substitution arc step 2 cycle 9.
