<header><span class="badge">2026-05-26</span><h1>VLC Seek Range Cache Priming</h1><p class="summary">Dreamio now primes local VLC range-cache seeks from stable 1 MB boundaries behind the estimated target, retains useful nearby bytes under a bounded budget, and logs foreground misses with more precision.</p></header>
<section class="panel"><h2>Summary</h2><p>Reduced post-seek buffering risk in native VLC playback by making seek and jump prefetch conservative behind the target instead of only racing ahead from the estimated byte offset.</p></section>
<section class="panel"><h2>Changes Made</h2><ul><li>Added seek-specific prefetch through <code>prefetchForSeek</code>, with a 4 MB backward prime window and user-initiated task priority for the first chunks.</li><li>Aligned prefetch chunks to global 1 MB boundaries so repeated VLC requests reuse stable cached ranges.</li><li>Replaced prefetch-window eviction with a 64 MB bounded cache budget that preserves active playback, recent seek, header, and tail/index ranges.</li><li>Changed foreground miss handling to fetch only missing subranges and log <code>uncached</code> versus <code>partial-miss</code>.</li><li>Routed VLC delegate state handling onto the main actor before reading player state or firing UI callbacks.</li><li>Added tests for the observed VLC request pattern, global chunk alignment, and budget retention.</li></ul></section>
<section class="panel"><h2>Context</h2><p>A 15-second skip estimated byte <code>213615760</code>, while VLC’s first real read started at <code>212942432</code>. The old prefetch overlapped the request but missed its front edge, then eviction could discard ranges that were still useful during the next VLC probes.</p></section>
<section class="panel"><h2>Important Implementation Details</h2><ul><li>The observed request and estimated seek offset both fall inside global chunk <code>212860928-213909503</code>, so seek priming now warms that chunk before later ahead chunks.</li><li>Normal prefetch still prefers the playhead area, while seek prefetch starts at the backward-biased window start.</li><li>Cache eviction removes unprotected segments farthest from protected areas until the byte budget is met; protected ranges are not trimmed simply because a new prefetch window appears.</li><li>Foreground reads cancel or reprioritize normal prefetch when VLC asks outside the expected area.</li></ul></section>

<section class="panel"><h2>Expected Impact for End-Users</h2><p>Short backward or forward skips in MKV/direct-file playback should resume with fewer full foreground misses, especially when VLC asks slightly before Dreamio’s estimated byte position.</p></section>

<section class="panel"><h2>Issues, Limitations, and Mitigations</h2><ul><li>No device playback check was run in this turn, so real MobileVLCKit timing still needs confirmation on hardware.</li><li>The cache remains memory-only. The 64 MB budget limits growth while retaining the ranges most likely to matter after seeks and MKV index probes.</li><li>The existing MobileVLCKit/OpenGLES warning is treated as internal unless it persists after the main-actor cleanup.</li></ul></section>
<section class="panel"><h2>Follow-up Work</h2><ul><li>Manually test MKV skip behavior on device and compare DEBUG logs for post-seek <code>hit</code>, <code>partial-miss</code>, and <code>uncached</code> reads.</li><li>Consider exposing cache budget tuning if device memory pressure shows up in longer playback sessions.</li><li>Track any persistent VLCOpenGLES2VideoView warnings separately with device logs if they continue.</li></ul></section>
<section class="panel"><h2>New Changes as of 2026-05-26 00:40 EDT</h2><h3>Summary of changes</h3><p>Adjusted the cache to follow VLC's actual foreground read area even when those reads are hits, and changed foreground partial misses to fetch stable aligned chunks synchronously.</p><h3>Why this change was made</h3><p>Device logs showed a backward jump estimating byte <code>15936567</code>, while VLC continued reading from about <code>27165812</code> through the warmed cache. Because those reads were hits, prefetch stayed near the estimate until VLC reached the cache edge and began partial misses.</p><h3>Code diffs</h3><section class="diff-file"><h3>Dreamio/ProgressiveHTTPRangeCache.swift</h3><svg data-icon-sprite aria-hidden="true" width="0" height="0">

<h2>New Changes as of May 26, 2026 at 10:52 AM EDT</h2>
<h3>Summary of changes</h3>
<p>Updated the local HTTP range cache prefetch bookkeeping after reviewing fresh device logs from normal playback and a warmed-cache 15 second skip. Normal cold-cache misses are expected, but the warmed-cache skip showed the foreground read moving behind the active prefetch cursor while older prefetch state could still finish and mutate session state.</p>
<h3>Why this change was made</h3>
<p>The cache should follow the bytes VLC is actually reading after a skip, not keep stale prefetch state alive after a newer foreground read has reoriented the cache. This update makes canceled prefetch workers stop before inserting fetched bytes after cancellation and prevents stale workers from clearing newer active prefetch state.</p>
