…, SP2) Ports the latency- and WiFi-jitter-relevant subset of the Apollo perf-curated branch onto Vibepollo, adapted to Vibepollo's code structure. DS5 customizations were intentionally excluded (obsolete via the CTM bridge). Knobs already present in Vibepollo (min_qp, filler_data, split_encode, weighted_prediction) were skipped. - AP1: configurable RTP send-pacing bandwidth (pacing_max_bitrate_kbps). Replaces the hardcoded ~80%-of-1Gbps pacer that no-ops on WiFi links and lets AMPDU aggregation amplify per-frame bursts into 30-60ms inter-arrival spikes. 0 = legacy. Includes a 1-packet/ms floor. - AP6: raise videoBroadcastThread + sync/async encode threads high->critical; audioBroadcastThread stays high. - AP9: expose nvenc_temporal_aq with NV_ENC_CAPS_SUPPORT_TEMPORAL_AQ probe. - SP1: server-side packetsize cap (200..65535) to avoid fragmentation on low-MTU links. - SP2: harden intra-refresh - add outputRecoveryPointSEI to the HEVC path and add the previously-missing H264 intra-refresh block (caps-probe + recoveryPointSEI + single-slice). Activates when the client negotiates enableIntraRefresh. Web-UI strings and docs intentionally omitted; keys are sunshine.conf-only.

Ports the latency- and WiFi-jitter-relevant subset of an Apollo perf-curated branch onto Vibepollo, adapted to Vibepollo's code structure. All knobs default to legacy behaviour, so nothing changes unless explicitly enabled. Knobs already present in Vibepollo (
min_qp,filler_data,split_encode,weighted_prediction) were skipped, and DS5-specific customizations were intentionally excluded.Changes
