<li>Consider a follow-up Beads issue only if device testing shows the 30-second cache should be adjusted or made configurable.</li>

<h2>New Changes as of 2026-05-25 15:20 EDT</h2>
<h3>Summary of changes</h3>
<p>After device testing showed VLC still reported <code>state=buffering</code> on 15-second skip actions, the native backend now also applies <code>:live-caching</code> with the same centralized 30-second value and prints DEBUG seek/jump telemetry.</p>
<h3>Why this change was made</h3>
<p>Some VLC inputs can use the live/access cache path even when the app treats them as direct native streams. Adding <code>:live-caching</code> keeps the cache policy consistent across VLC's relevant access paths. The new logs help distinguish normal post-seek buffering from a longer restart-like stall.</p>
