# A szállított ffmpeg teljes forrása / Complete source of the bundled ffmpeg

GENERÁLT FÁJL — `app/tools/ffmpeg-sources.js` írja a `vendor/ffmpeg/build/sources.lock`-ból; kézzel nem szerkesztjük.
GENERATED FILE — written by `app/tools/ffmpeg-sources.js` from `vendor/ffmpeg/build/sources.lock`; do not edit by hand.

**HU.** A MAPu mellé csomagolt `ffmpeg.exe` / `ffprobe.exe` a MAPu saját, forrásból fordított,
statikus buildje (`ffmpeg-n8.1.2-54-gc573a95381-mapu1`), a GNU GPL v3 alatt terjesztve. A GPL v3 6. §-a szerint
ehhez a binárishoz a **teljes megfelelő forráskód** jár: az FFmpeg forrása, **minden befordított
könyvtár forrása** pontosan abban a változatban, amiből a bináris készült, és a **fordítást
vezérlő szkriptek**. Ez a fájl az a jegyzék: a könyvtárak az **eredeti fejlesztői tárolójukra**
mutatnak, a pontos commit címén (GPL v3 6(d): a forrás harmadik fél szerverén, világos
útmutatással a bináris mellett). A fordítás receptje (a `build.sh`, `build.ps1`,
`components.sh`, `sources.lock`) a telepítés `resources\vendor\ffmpeg\build\` mappájában
van, és a https://mapu.hu/ffmpeg-src/ címen is. A MAPu minden tételről **megőrzött másolatot** tart (a lenti
fájlnév és SHA256); ha egy eredeti cím megszűnik, az a csomag a https://mapu.hu/ffmpeg-src/ címre kerül
fel — vagy írj a kotysoftc@gmail.com címre.

**EN.** The `ffmpeg.exe` / `ffprobe.exe` bundled with MAPu is MAPu's own static build
(`ffmpeg-n8.1.2-54-gc573a95381-mapu1`), compiled from source and distributed under the GNU GPL v3. Under section 6
of the GPL v3 this binary comes with its **complete Corresponding Source**: the FFmpeg source,
the source of **every statically linked library** at exactly the revision the binary was built
from, and the **scripts that control the build**. This file is that list: the libraries point at
their **original upstream repositories**, at the exact commit (GPL v3 6(d): source on a third
party's server, with clear directions next to the binary). The build recipe (`build.sh`,
`build.ps1`, `components.sh`, `sources.lock`) is in the installation's
`resources\vendor\ffmpeg\build\` folder, and at https://mapu.hu/ffmpeg-src/ as well. MAPu keeps a
**retained copy** of every item (file name and SHA256 below); should an upstream address
disappear, that archive is published at https://mapu.hu/ffmpeg-src/ — or write to kotysoftc@gmail.com.

A `toolchain` sorok a fordító futásidejű részei, amik a statikus binárisba kerülnek (mingw-w64 CRT
és winpthreads, a GCC libgcc / libstdc++ / libgomp könyvtára, GCC Runtime Library Exception): a GPL
v3 1. §-a szerint ezek rendszerkönyvtárak, a forrásuk a teljesség kedvéért szerepel. / The
`toolchain` rows are the compiler's run-time parts that end up in the static binary (mingw-w64 CRT
and winpthreads, GCC's libgcc / libstdc++ / libgomp under the GCC Runtime Library Exception): System
Libraries under GPL v3 section 1, listed for completeness.
