NVDEC — Декодирование
Что такое NVENC и NVDEC?
NVENC (NVIDIA Encoder) — выделенный аппаратный блок на GPU, который кодирует видео параллельно с работой CUDA-ядер. Используется в OBS Studio, FFmpeg, DaVinci Resolve и десятках других приложений для стриминга, записи экрана и рендеринга видео.
NVDEC (NVIDIA Decoder) — аппаратный декодер, разгружающий CPU при воспроизведении видео. Критично для видеонаблюдения, медиасерверов и AI-пайплайнов с видеовходом.
AV1 — кодек нового поколения с лучшим качеством на низком битрейте. Аппаратная поддержка NVENC AV1 появилась начиная с Ada Lovelace (RTX 40xx, 8th Gen NVENC).
Поколения NVENC
1st Gen (Kepler) — первый аппаратный энкодер. H.264 4:2:0. До 8x realtime 1080p.
2nd Gen (Maxwell 1st) — добавлена поддержка YUV 4:4:4, lossless-кодирование H.264.
3rd Gen (Maxwell 2nd) — первая поддержка H.265/HEVC. Кодирование 4K@60.
4th Gen (Pascal) — HEVC Main10 (10-бит), 8K, SAO, lossless HEVC. 2x производительность.
5th Gen (Volta) — аналогичен Pascal. Встречается в ранних Turing (GTX 1650).
6th Gen (Turing) — HEVC B-frames. Экономия битрейта 25% (HEVC), 15% (H.264). Качество на уровне x264 medium.
7th Gen (Ampere) — аналогичен Turing. AV1 только декодирование (NVDEC).
8th Gen (Ada Lovelace) — первый аппаратный AV1-энкодер. 8K 10-бит @60fps. Dual NVENC на старших чипах.
9th Gen (Blackwell) — добавлена поддержка 4:2:2 chroma (H.264, HEVC). AV1 UHQ-режим. До 3 NVENC на RTX 5090.
Поколения NVDEC
1st Gen (Maxwell 1st) — базовое декодирование: MPEG-1/2/4, VC-1, H.264.
2nd Gen (Maxwell 2nd, GM206) — первая поддержка VP9 и HEVC-декодирования (до 10-бит).
3rd Gen (Pascal, Volta) — добавлен 12-бит VP9 и HEVC.
4th Gen (Turing) — полное покрытие HEVC: 4:2:0, 4:2:2, 4:4:4 до 12-бит. H.264 4:2:2.
5th Gen (Ampere, Ada Lovelace) — первый аппаратный AV1-декодер. Film grain support.
6th Gen (Blackwell) — восстановлена полная поддержка HEVC 4:2:2/4:4:4. 2x пропускная способность H.264. До 2 NVDEC на старших чипах.
