Video Tools: engine and source

QoTool uses the unmodified @ffmpeg/core 0.12.10 single-thread WebAssembly binary (GPL-2.0-or-later), built from FFmpeg 5.1.4. The JavaScript API is @ffmpeg/ffmpeg 0.12.15 (MIT). Splitting the binary for hosting does not change its bytes. No iLoveVideo code, branding or remote processing service is bundled.

The build uses Emscripten 3.1.40 and enables GPL codecs, including x264 and x265. Other components include libvpx, LAME, Theora, Vorbis, Opus, zlib, WebP, FreeType, FriBidi, libass and zimg. Their source locations, versions and build scripts are identified in the linked build recipe and repository; their individual notices accompany those sources. FFmpeg is copyright its respective contributors, 2000–2023. This integration is not endorsed by FFmpeg.
