BV (Bug Video)

Bangumi is an unofficial mobile client for the bgm.tv media-tracking and discussion site, built with React Native for iOS and Android. It manages progress for anime, music, Japanese dramas, games, and visual novels, and provides mobile interfaces for entries, characters, timelines, posts, user spaces, searches, rankings, calendars, tags, logs, groups, and other site sections. The client adds features beyond the website, including limited synchronization from bilibili and Douban, a CDN-backed data layer for cover images and static data, episode-level streaming-source information, local folder management with Romanized-title scraping, image previews, word clouds, recommendation and related-series views, filtering rules, user blocking, and several specialized browsing and game-like interfaces. It does not provide media downloads, direct playback, or modification, according to the project disclaimer. The project is distributed as an Android application and through available iOS sideloading methods; its README says Google Play distribution is suspended and that iOS App Store resubmission is not planned. The repository describes the code as intended for learning and noncommercial use.

wiliwili is an open-source third-party Bilibili client designed for gamepad users. It runs on desktop Linux, macOS, and Windows systems as well as Nintendo Switch, PlayStation Vita, PlayStation 4, and Xbox platforms, and supports touch, mouse, keyboard, and gamepad input. The client provides Bilibili browsing features including search, recommendations, followed-creator updates, live streams, video and media playback, comments, danmaku, QR-code login, viewing history, favorites, followed series, and user pages. It supports simplified and traditional Chinese, Japanese, Korean, and English interfaces, light and dark themes, configurable fonts and icons, and optional Anime4K processing. Its interface is rendered with NanoVG, while video playback uses FFmpeg and MPV. Platform input and window functionality can use GLFW or SDL, with graphics backends including OpenGL and platform-specific implementations such as D3D11, Deko3D, and GXM. The repository provides platform-specific builds and build instructions, including Switch OpenGL and Deko3D variants, PSVita builds, and desktop compilation.

VirtualApp (VA) is an Android sandbox and virtualization SDK that runs applications inside an isolated internal space without installing them into the Android system. It is intended for integrating into host applications and supports use cases such as app cloning, multiple app instances, internal APK installation, app control, and plugin development. Its framework proxies requests between virtual applications and the Android framework, rewriting installation-related and other app parameters so the system treats the requests as belonging to the host. A native layer redirects file I/O to the virtual installation path and hooks functions that cannot be handled at the framework layer. The runtime includes host, plugin, virtual-app client, VA Server, and child processes; separate main and plugin packages support 32-bit and 64-bit applications. The SDK also provides Java and native hook capabilities, file and component isolation, and APIs for starting the engine, installing a package for a user, and launching an app. The repository states that its public code stopped updating in December 2017 and directs users needing the continuously updated business edition to obtain a commercial license. It describes support for Android 5.0 through 17.0, ARM 32-bit and 64-bit processors, and 32-bit and 64-bit applications.

Bili23-Downloader is an open-source, free, cross-platform desktop downloader for Bilibili, developed and maintained by Scott Sloan. It supports Windows, Linux, and macOS, with a Fluent Design interface, light and dark themes, multithreaded downloads, resumable transfers, automatic retries, bandwidth limits, proxy configuration, clipboard monitoring, and multilingual UI support. The application parses videos, series, films, courses, interactive videos, music, user spaces, favorites, watch history, playlists, and related Bilibili collections. It can select video and audio qualities and codecs, preview media before downloading, save danmaku and subtitles in formats including XML, ASS, JSON, SRT, LRC, and TXT, preserve cover images, write chapter and NFO metadata, and package output as MP4 or MKV. It also provides configurable naming and directory rules, duplicate-download detection, account login through QR code, SMS verification, or cookies, and optional embedding of ASS danmaku or subtitles into MKV files. The project is released under the GPL-3.0 license.
