Version 1.5.1

English

• Product rename: VR Video Passthrough Server is now Thru3D Media Server. Updated application titles, the default DLNA server name, documentation, and product images. The Windows executable is now Thru3D_Media_Server.exe, and the full package folder is named Thru3D_Media_Server.
• Thru3D Media Player compatibility: Added the player to the compatibility table. Player and Server are separate applications that can also work together; choose Alpha passthrough when streaming to Thru3D Media Player. The server continues to provide green-screen output for other compatible players.
• Offline VR source selection: Single-file and batch passthrough conversion now offer Auto Detect, VR180, and Fisheye modes. Fisheye FOV supports 140°–280° in 10° steps, including 180°, 190°, and 200°. Manual selection overrides filename detection, and output names reflect the selected projection.
• Improved DLNA external subtitles: Improved discovery and delivery of same-stem SRT, ASS, SSA, and WebVTT files, including language suffixes. Fixed matching for mixed-case and bracketed filenames, subtitle-cache refresh after file changes, and subtitle metadata for individual videos. External subtitles work independently of realtime subtitle burning; display and track selection depend on the player.
• Updated website and documentation: Refreshed the Chinese, English, and Japanese website and product documentation to introduce Thru3D Media Player and Thru3D Media Server separately.

Upgrade note: Close the application and server before updating. Extract an update package over the matching full installation, then launch Thru3D_Media_Server.exe and update old shortcuts. The old VR_Video_Passthrough_Server.exe is not automatically removed. Settings remain in runtime_cache/ui_settings.json; copy this file if moving to a new folder. Custom DLNA server names are preserved.

See CHANGELOG.md for the detailed history. Website: thru3d.com.

Patch 1:

• More stable alpha-channel video playback: Character masks no longer flicker briefly upon startup or seeking.
• Thru3D Media Player compatibility: When used with the latest version of Thru3D Media Player, both virtual MP4 and live modes play correctly. The fix was implemented on the player side (previously, virtual MP4s would stop after a few seconds and live streams would fail to start), so please update the player as well; no additional configuration is required for this server version.
• Official website link update: The official website link on the management page has been updated to https://thru3d.com.

中文

• 产品更名： “VR视频透视服务器”（VR Video Passthrough Server）正式更名为 “Thru3D媒体服务器”（Thru3D Media Server）。同步更新软件标题、默认 DLNA 名称、文档与产品图片。Windows 启动程序改为 Thru3D_Media_Server.exe，完整包目录名改为 Thru3D_Media_Server。
• Thru3D Media Player 兼容信息： 兼容表加入该播放器。Player 与 Server 是两款独立软件，也可搭配使用；向 Thru3D Media Player 推送透视视频时请选择 Alpha 透视，服务器继续为其他兼容播放器提供绿幕输出。
• 离线透视新增原始 VR 模式： 单文件与批量转换可选择自动识别、180VR、鱼眼。鱼眼角度支持 140°–280°，每档 10°，包含 180°、190°、200°等常见角度。手动选择可覆盖文件名识别，生成文件名同步反映所选投影。
• 增强 DLNA 外挂字幕兼容性： 完善同名 SRT、ASS、SSA、WebVTT 及语言后缀字幕的发现与下发。修复大小写混用、方括号文件名匹配、字幕文件变动后的缓存刷新，以及单个视频的字幕元数据。外挂字幕独立于实时字幕烧录开关，显示与字幕切换取决于播放器支持情况。
• 更新官网与文档： 中、英、日三语官网和产品文档同步更新，分别介绍 Thru3D Media Player 与 Thru3D媒体服务器。

升级提示： 更新前关闭软件与服务器。更新包请覆盖到对应的完整安装目录，之后启动 Thru3D_Media_Server.exe 并更新旧快捷方式；旧的 VR_Video_Passthrough_Server.exe 不会自动删除。设置仍保存在 runtime_cache/ui_settings.json，迁移到新目录时可复制该文件，自定义 DLNA 名称继续保留。

完整更新历史见 CHANGELOG.md。官网：thru3d.com。

补丁1:
-Alpha 透视起播更稳定： 起播或跳转后人物遮罩不再闪烁一阵子。

  更多见 CHANGELOG.md.

Version 0.1.0 Beta 4 Patch 1

• Patch 1: File naming allows the player to automatically recognize the playback mode #1 . Tested Heresphere/Skybox/4XVR/MoonVR/DeoVR

• Major update: Added foreground-only Light Matching for realtime passthrough, including a dedicated Home-page panel, presets, custom settings dialog, persisted UI settings, and live runtime updates during playback.

• Major core update: Added DLNA [NoLive] labeling and realtime-source rejection for known unsupported live sources, avoiding confusing realtime fallback attempts.

• Major bug fix: Offline generation now targets the source video bitrate by default for all engines, including RVM fast/balanced and MatAnyone2 medium/slow. This keeps generated video size closer to the original source. If source bitrate is unavailable, offline generation falls back to 40 Mbps.

• Major bug fix: Fixed lingering FFmpeg child processes after playback or server stop. PyNv streams now track and stop audio FFmpeg subprocesses, wait for slate audio/cache threads during close, clean up partially spawned pipe-TS muxers, remove stale temporary AAC files, and forced UI server stop now terminates child processes through taskkill /T /F on Windows.

• Major bug fix: Fixed realtime 2D alpha blocks turning gray during playback by switching the default realtime RVM model back to FP32. The issue was caused by FP16 precision loss accumulating in RVM's recurrent rec1-rec4 state across frames, not by alpha packing or realtime bitrate control.

• Major bug fix: Fixed MatAnyone2 medium offline alpha prepass crashes on HEVC Main10/P016-style decoded frames by converting 16-bit NV12/P010 planes to 8-bit BGR before YOLO-World/EfficientSAM or SAM3 prepass processing.

• Major bug fix: Updated AV1 backend routing so GPUs without AV1 NVDEC support, such as RTX 20/Turing, use the FFmpeg decode fallback instead of failing later inside PyNv decode.

• 补丁1： 文件命名，让播放器可以自动识别播放模式 #1 。测试了Heresphere/Skybox/4XVR/MoonVR/DeoVR

• 重大更新： 新增实时透视前景光照匹配功能，包括首页独立面板、预设、自定义设置对话框、持久化 UI 设置，以及播放中的运行时更新。

• 重大内核更新： 新增 DLNA [NoLive] 标记，并对已知不支持实时处理的源直接拒绝实时入口，避免误走实时 fallback。

• 重大 BUG 修复： 所有离线生成引擎默认改为按源视频码率输出，包括 RVM 快速/均衡和 MatAnyone2 中速/慢速，使生成文件大小更接近原始视频。读取不到源码率时回退到 40 Mbps。

• 重大 BUG 修复： 修复播放或停止服务器后 FFmpeg 子进程后台常驻的问题。PyNv 流现在会跟踪并停止音频 FFmpeg 子进程，关闭时等待 slate 音频/缓存线程，清理部分启动失败的 pipe-TS muxer，删除残留临时 AAC 文件；UI 强制停止服务器时也会在 Windows 上通过 taskkill /T /F 终止子进程。

• 重大 BUG 修复： 修复 MatAnyone2 中速离线 alpha 在 HEVC Main10/P016 风格解码帧上的前置识别崩溃，YOLO-World/EfficientSAM 或 SAM3 预处理前会先把 16-bit NV12/P010 平面转换成 8-bit BGR。

• 重大 BUG 修复： 更新 AV1 后端路由，RTX 20/Turing 等不支持 AV1 NVDEC 的显卡会走 FFmpeg 解码 fallback，不再等到 PyNv 解码取帧阶段才失败。
