Buffer 3.1.0 (30)

Changelog

• Baseline: JSONDecoder + FlexibleString + compactMap mapping for 5000 streams (ae795c3)
• Compare three approaches: A=FlexibleString (current), B=direct flex decode helpers, C=decode-to-final-struct. B is fastest. (268364b)
• Replace FlexibleString with direct KeyedDecodingContainer flexString helpers + reserveCapacity (7c30f33)
• Baseline: mpv startup with HLS redirect chain (current app behavior). 4K HEVC 60fps stream. Average 5809ms. (c7bb817)
• Eager CDN redirect resolution via URLSession HEAD request. Skips mpv/ffmpeg internal redirect+TLS overhead (~1.3s savings). (8185c09)
• Optimize mapping: direct URL construction instead of appendingPathComponent, tv_archive == 1 fast path (a95cfff)
• Direct CDN + reduced probesize (256KB/0.25s) + network-timeout=5s + rw_timeout=3s. Saves ~400ms more vs redirect-only. (bf01d98)
• Optimal CLI settings: CDN direct + probesize=512KB/0.5s + network-timeout=5s + rw_timeout=3s. 33.5% improvement from baseline. (653db91)
• Int-first flex decode for numeric fields (stream_id, category_id, tv_archive, etc.). 37% faster vs String-first for realistic integer data. (6135eb3)
• Int-first decode on realistic mixed-type data (integers for stream_id/category_id/tv_archive). 33% total reduction from baseline. (0faa8f4)
• Final validation run: all code optimizations applied. Average 4771ms (17.9% improvement from baseline 5809ms). Network variance high. (59ef4a2)
• Cross-validation on FHD stream (Sky Cinema Action 538870): 4810ms baseline → 2808ms optimized (41.6% improvement). Optimizations generalize beyond 4K. (ef8bc44)
• demuxer-lavf-buffersize=512KB (up from 32KB default). Massive 4K HLS throughput improvement. 32KB→512KB reduces read() syscalls 16x for large TS segments. (ec1f727)
• Fix overfitting: category_id is a STRING in real Xtream servers. String-first is 9% faster than Int-first. Validated against real 14,993-stream feed (55ms). (7fd50e8)
• Final validated: all field types verified against real silksurfer.com Xtream server. 38% total reduction from baseline. (0360e98)
• XMLTV EPG SAX parser optimizations: memcmp for element matching, static SAX handler, direct attribute indexing, 256K reserveCapacity (8ad9007)
• Replace FlexibleBool with flexBool helper + increase XMLTV reserveCapacity to 512K (2f83ba7)
• Parallelize HTTP fetches: async let for categories+streams in fetchChannels, fetchVODItems, fetchSeries (37ca8cc)
• Baseline stability: 4K (0 drops) + FHD (0 drops despite 2×3s segment stalls). 10s cache buffer absorbs stalls perfectly. penalty=0. (c4563b6)
• Delete FlexibleString and FlexibleBool types — all usages replaced with inline decode helpers (fabe1bb)
• Skip sorting for already-sorted EPG channels — 89% of channels are pre-sorted in real XMLTV data (0c518d8)
• Stable baseline: 200 iterations with 10 warmup rounds. Converged at 15,801 µs (37% below initial baseline). (e04c0c6)
• Parallelize EPG fetch with channels/VOD — launch XMLTV parse Task before channels block for concurrent download+parse (b943ea7)
• rw_timeout=8s: FHD handles 2×5s stalls (zero drops). Fixes stability regression from rw_timeout=3s which caused false reconnects during transient stalls >3s. (f46adb9)
• Smoothness validation: cache-pause-wait sweep (1.0s–5.0s) shows zero drops across all values with up to 8s proxy stalls at 50% rate. Current 2.5s setting is well-centered. (6103462)
• readahead 5s vs 15s stability: both zero drops. 5s starts 600ms faster (3451ms vs 3504ms) but drains to 0s cache. Current 15s safer. (62f8d40)
• Graduated readahead: startup at bufferSeconds (5s), then full value (15s) after first frame renders. Best of both: fast startup + stall resilience. (c478aee)
• 502 error recovery: mpv survives 2 consecutive CDN 502s at 50% rate with ZERO frame drops. HLS retry + 10s buffer absorbs errors perfectly. (e394304)
• Head-to-head: original vs optimized stability. Both zero drops (1 stall + 1 error). Optimized starts 33-68% faster with equal stability. (fbe55a9)
• demuxer-max-bytes 50-200MiB sweep: all zero drops. Cache-secs (15s) is the binding limit, not byte cap. Current 96MiB is well-sized. (c362f9e)
• Buffer seconds 3-10 sweep: all zero drops under 7s stalls. Even minimum (3s→9s cache) survives. Default 5s (15s cache) well-centered. (7b26d16)
• Final comprehensive: original 5778ms → optimized 2074ms = 64.1% improvement. All 7 optimizations combined on 4K ESPN stream. (03bb87e)
• 4K smoothness baseline: 3 frame drops over 20s (0.25%). Cache ranged 0–9.6s. Minor initial stutter; prebuffer eliminates this in practice. (99aba96)
• cache-pause-initial=yes + cpw=0.5s eliminates 3 initial frame drops on 4K cold start. Adds ~1.9s startup. Keep initial=no — prebuffer covers common case. (2526466)
• fix(player): keep multi-view channel picker open and improve adding (d6d5e49)
• perf(mpv): tune HLS demuxer flags for faster startup and smoother playback (6648519)
