Final session summary: H264 + VP9 + HEVC frame 1 byte-equal to SW
Bug 4 (H264 keyframe-partial): FIXED.
Bug 5 (HEVC libva all-zero): partial fix, frame 1 byte-equal.
Root cause: rkvdec_s_ctrl -EBUSY when first SPS triggers image_fmt
reset on busy CAPTURE queue (libva pre-allocates buffers at
CreateContext, kernel blocks the reset).
Fix: 90-LOC synthetic SPS injection in libva CreateContext before
cap_pool_init pre-seeds ctx->image_fmt.
Remaining: HEVC frame 2+ (ffmpeg-vaapi slice_data 40-byte inflation),
MPEG-2/VP8 (libva multi-device probe). Both deferred.
