- fix: stop playback when anchor block entity unloads (BLOCK_ENTITY_UNLOAD)
so deleting a video while audio is playing actually silences it.
- fix: force-stop SourceDataLine and grabber from outside the worker thread
so a blocked line.write() / grab() unblocks immediately on close.
- perf: tune FFmpeg streaming options (buffer_size, probesize, analyzeduration,
max_delay, fflags=+genpts, reconnect_delay_max) and pre-size audio line buffer
to ~0.5s to smooth out mid-stream stutter.
- feat: /videopreload <url> broadcasts a S2C PreloadPayload to all clients;
each client downloads the URL to <gameDir>/video_player_cache/<sha256> and
subsequent playback reads from the local file instead of streaming.
Gated by COMMANDS_GAMEMASTER (op level 2), so command blocks can invoke it.
JavaCPP Loader (javacpp.jar) ships pure-Java code that needs its own
JNI bridge DLL (jnijavacpp) to extract & link other native libraries.
That bridge lives in the platform-specific javacpp-<os>-<arch>.jar
which the old install guide silently omitted — users following it
ended up with a black panel and an UnsatisfiedLinkError for jnijavacpp
because FFmpeg natives could never be loaded.
This bumps the required JavaCV jar list from 4 to 5, updates the
-Xbootclasspath/a: examples on all three OSes, and adds a diagnostic
note for the matching log line.
Docs-only change; mod code is unchanged from v0.4.2.
Reviewer caught that the README still pointed users at video_player-0.4.1.jar
even though 0.4.2 fixes the stick missing-model issue. Updated:
- "current version" header → 0.4.2
- STEP 4 download filename → video_player-0.4.2.jar
- build output path → build/libs/video_player-0.4.2.jar
- STEP 6 verification: explicitly call out that 0.4.1 and below have a known
stick-icon defect (unprefixed item/generated parent rejected by the 26.1.2
model loader) so users on those versions need to upgrade, not just dedupe.

User followed README using %APPDATA% in -Xbootclasspath/a: and the official
Mojang launcher passed the literal string through to Java without expanding
it, so boot classpath ended up empty and video stayed black despite all 4
JavaCV jars being present.
Replaced the %APPDATA% example with an absolute C:\Users\<name>\AppData\
Roaming\... template, added a callout warning that the launcher does not
expand env vars in JVM args, and pointed at `echo %APPDATA%` from cmd as the
way to discover the right path.
Also corrected the ffmpeg jar filenames: the bundle zip uses the short form
(e.g. ffmpeg-windows-x86_64.jar), not the Maven-style
ffmpeg-8.0.1-1.5.13-windows-x86_64.jar.

User reported Incompatible-mods crash because they downloaded
fabric-api-0.140.2+1.21.11.jar from Modrinth (Modrinth's version-filter URL
param does not always restrict the listing to the requested game version).
Replaced the generic search-page link with the direct CDN URL of
fabric-api-0.149.0+26.1.2.jar and added a callout telling readers to verify
the filename suffix ends in +26.1.2.jar.

Previous README used "방법 A/B/C" terminology that confused readers and
recommended Prism over the official launcher. Per user feedback, restructured
into a step-by-step guide assuming the official Mojang launcher:
1. boot 26.1.2 vanilla once to create .minecraft
2. run fabric-installer-1.x for client / 26.1.2 / loader 0.19.2
3. open .minecraft/mods (per-OS instructions)
4. drop fabric-api + video_player-0.4.1.jar, remove old versions
5. install JavaCV — two routes:
5-A. Prism Launcher (easiest)
5-B. official launcher via -Xbootclasspath/a: with Windows/macOS/Linux examples
6. verify with /videostick
Moved Maven coords to a developer footnote. Added install verification step
to disambiguate "missing texture" symptom from leftover old-version jars.
