serge_shubin 7ade6fbe5e Server-side demo recording and playback (netdemo) 
Complete netdemo feature as a single commit on implant2.
See svdemo.txt for full documentation.

Recording: svdemo_record, delta compression, keyframes, auto-record,
chat capture, configstring tracking, map_restart handling.

Playback: svdemo_play, free camera (client-owned), follow mode,
pause, seek/seekexact with keyframes, scoreboard, PVS via usercmd
origin, SNAPFLAG_RESET_ENTITIES for clean transitions.

+ Introduction
+
+ LZ4 is lossless compression algorithm, providing compression speed >500 MB/s per core,
+ scalable with multi-cores CPU. It features an extremely fast decoder, with speed in
+ multiple GB/s per core, typically reaching RAM speed limits on multi-core systems.
+
+ The LZ4 compression library provides in-memory compression and decompression functions.
+ It gives full buffer control to user.
+ Compression can be done in:
+ - a single step (described as Simple Functions)
+ - a single step, reusing a context (described in Advanced Functions)
+ - unbounded multiple steps (described as Streaming compression)
+
+ lz4.h generates and decodes LZ4-compressed blocks (doc/lz4_Block_format.md).
+ Decompressing such a compressed block requires additional metadata.
+ Exact metadata depends on exact decompression function.
+ For the typical case of LZ4_decompress_safe(),
+ metadata includes block's compressed size, and maximum bound of decompressed size.
+ Each application is free to encode and pass such metadata in whichever way it wants.
+
+ lz4.h only handle blocks, it can not generate Frames.
+
+ Blocks are different from Frames (doc/lz4_Frame_format.md).
+ Frames bundle both blocks and metadata in a specified manner.
+ Embedding metadata is required for compressed data to be self-contained and portable.
+ Frame format is delivered through a companion API, declared in lz4frame.h.
+ The `lz4` CLI can only manage frames.

+/*! In-place compression and decompression
+ *
+ * It's possible to have input and output sharing the same buffer,
+ * for highly constrained memory environments.
+ * In both cases, it requires input to lay at the end of the buffer,
+ * and decompression to start at beginning of the buffer.
+ * Buffer size must feature some margin, hence be larger than final size.
+ *
+ * |<------------------------buffer--------------------------------->|
+ * |<-----------compressed data--------->|
+ * |<-----------decompressed size------------------>|
+ * |<----margin---->|
+ *
+ * This technique is more useful for decompression,
+ * since decompressed size is typically larger,
+ * and margin is short.
+ *
+ * In-place decompression will work inside any buffer
+ * which size is >= LZ4_DECOMPRESS_INPLACE_BUFFER_SIZE(decompressedSize).
+ * This presumes that decompressedSize > compressedSize.
+ * Otherwise, it means compression actually expanded data,
+ * and it would be more efficient to store such data with a flag indicating it's not compressed.
+ * This can happen when data is not compressible (already compressed, or encrypted).
+ *
+ * For in-place compression, margin is larger, as it must be able to cope with both
+ * history preservation, requiring input data to remain unmodified up to LZ4_DISTANCE_MAX,
+ * and data expansion, which can happen when input is not compressible.
+ * As a consequence, buffer size requirements are much higher,
+ * and memory savings offered by in-place compression are more limited.
+ *
+ * There are ways to limit this cost for compression :
+ * - Reduce history size, by modifying LZ4_DISTANCE_MAX.
+ * Note that it is a compile-time constant, so all compressions will apply this limit.
+ * Lower values will reduce compression ratio, except when input_size < LZ4_DISTANCE_MAX,
+ * so it's a reasonable trick when inputs are known to be small.
+ * - Require the compressor to deliver a "maximum compressed size".
+ * This is the `dstCapacity` parameter in `LZ4_compress*()`.
+ * When this size is < LZ4_COMPRESSBOUND(inputSize), then compression can fail,
+ * in which case, the return code will be 0 (zero).
+ * The caller must be ready for these cases to happen,
+ * and typically design a backup scheme to send data uncompressed.
+ * The combination of both techniques can significantly reduce
+ * the amount of margin required for in-place compression.
+ *
+ * In-place compression can work in any buffer
+ * which size is >= (maxCompressedSize)
+ * with maxCompressedSize == LZ4_COMPRESSBOUND(srcSize) for guaranteed compression success.
+ * LZ4_COMPRESS_INPLACE_BUFFER_SIZE() depends on both maxCompressedSize and LZ4_DISTANCE_MAX,

+===========================================================================
+ Серверные демо-записи (SVDEMO)
+ Руководство пользователя
+===========================================================================
+
+ОПИСАНИЕ
+--------
+
+Система серверных демо-записей позволяет записывать полное состояние
+игрового сервера (все сущности, все игроки) и воспроизводить запись
+с возможностью свободного перемещения камеры или просмотра от первого
+лица любого игрока.
+
+В отличие от обычных клиентских демо (запись только того, что видит
+один игрок), серверная запись содержит полную картину матча.
+
+
+КОНСОЛЬНЫЕ КОМАНДЫ
+------------------
+
+Запись:
+
+ svdemo_record <имя>
+ Начать запись серверного демо. Файл сохраняется в
+ svdemos/<имя>.svdm внутри игровой директории.
+
+ svdemo_stop
+ Остановить текущую запись или воспроизведение.
+ При остановке воспроизведения происходит отключение от сервера.
+
+Воспроизведение:
+
+ svdemo_play <имя>
+ Воспроизвести серверное демо. Загружает карту из записи,
+ подключает зрителя автоматически. Можно вызывать из меню,
+ из игры или во время просмотра другого демо.
+
+ svdemo_pause
+ Пауза / продолжение воспроизведения. Во время паузы камера
+ свободно перемещается, сущности заморожены.
+ На экране отображается "Playback Paused".
+
+ svdemo_seek <секунды>
+ Перемотка относительно текущей позиции. Положительное значение --
+ вперёд, отрицательное -- назад.
+ Перемещает к ближайшему ключевому кадру (точность ±5 сек).
+ Работает в паузе.
+ Пример: svdemo_seek -10 (назад на 10 секунд)
+
+ svdemo_seekexact <секунды>
+ Точная перемотка. Находит ближайший ключевой кадр, затем
+ прочитывает кадры до целевого времени. Точность до одного
+ серверного кадра (50 мс при sv_fps 20). Может занять долю
+ секунды на длинных перемотках. Работает в паузе.
+ Пример: svdemo_seekexact -10 (назад ровно на 10 секунд)
+
+
+НАСТРОЙКИ (CVARS)
+-----------------
+
+ svdemo_autorecord <0|1> (по умолчанию: 0)
+ Автоматическая запись демо при каждой загрузке карты.
+ Файлы именуются автоматически: <карта>_ГГГГММДД_ЧЧММСС.svdm
+ Пример: q3dm6_20260323_141530.svdm
+
+ svdemo_pauseEmpty <0|1> (по умолчанию: 1)
+ Пауза воспроизведения, когда нет подключённых зрителей.
+ Демо начинается с первого кадра при подключении зрителя.
+
+ svdemo_keyframeInterval <секунды> (по умолчанию: 5, 0 = выкл.)
+ Интервал ключевых кадров. Ключевые кадры позволяют перематывать
+ запись. Чем меньше интервал, тем точнее перемотка командой
+ svdemo_seek, но немного больше размер файла. Первый кадр
+ записи всегда является ключевым.
+
+ Все настройки сохраняются в конфигурации (CVAR_ARCHIVE).
+
+
+ЗАПИСЬ
+------
+
+1. Запустите сервер и начните игру как обычно:
+ devmap q3dm6
+
+2. Начните запись:
+ svdemo_record mymatch
+
+3. Играйте. Все действия всех игроков записываются.
+
+4. Остановите запись:
+ svdemo_stop
+
+ Запись также автоматически останавливается при:
+ - Смене карты (map, devmap, nextmap по таймлимиту/фраглимиту)
+ - Выключении сервера
+ Перезапуск карты (map_restart) НЕ прерывает запись.
+
+
+ВОСПРОИЗВЕДЕНИЕ
+---------------
+
+1. Запустите воспроизведение:
+ svdemo_play mymatch
+
+2. Карта загрузится автоматически. Вы подключитесь как зритель
+ со свободной камерой (полёт по карте).
+
+3. Управление зрителем:
+ - Свободная камера: перемещайтесь как обычный спектатор
+ - Следование за игроком: нажмите MOUSE1 (ATTACK) для входа
+ в режим следования и переключения между игроками
+ - Выход из следования: team spectator (можно забиндить)
+
+4. В режиме следования вы видите игру от первого лица выбранного
+ игрока с полным HUD: здоровье, броня, боеприпасы, оружие.
+
+5. Табло (TAB) показывает счёт записанных игроков.
+
+6. Управление воспроизведением:
+ - svdemo_pause -- пауза/продолжение
+ - svdemo_seek -10 -- быстрая перемотка назад на 10 сек
+ - svdemo_seek 30 -- быстрая перемотка вперёд на 30 сек
+ - svdemo_seekexact -10 -- точная перемотка назад на 10 сек
+ - svdemo_stop -- остановка и выход
+
+7. Воспроизведение останавливается автоматически при
+ достижении конца записи.
+

+- Заголовок: название карты, настройки сервера, конфигстроки
+ (имена игроков, модели, настройки игры)
+- Покадровые данные: дельта-сжатые состояния сущностей и игроков,
+ серверные команды (чат, принты), изменения конфигстрок
+- Ключевые кадры с индексом в конце файла
+
+Дельта-кодирование обеспечивает компактный размер файла.
+Типичный 10-минутный матч с 10 ботами занимает ~8 МБ.
+
+Одна запись = одна карта. При смене карты запись останавливается.
+
+
+ОГРАНИЧЕНИЯ
+-----------
+
+- Если в записанной игре было 64 игрока (MAX_CLIENTS), один
+ из них не будет виден при воспроизведении (его слот занят зрителем).
+- Воспроизведение требует наличия тех же pk3-файлов (карты, модели),
+ что использовались при записи.
+- Демо несовместимы между разными версиями движка, если изменился
+ формат сетевых структур.
+- При перемотке могут кратковременно отображаться визуальные артефакты
+ (частицы, вспышки) от локальных эффектов.
+
+
