 µStreamer is a lightweight and very quick server to stream [MJPEG](https://en.wikipedia.org/wiki/Motion_JPEG) video from any V4L2 device to the net. All new browsers have native support of this video format, as well as most video players such as mplayer, VLC etc.
 µStreamer is a part of the [PiKVM](https://github.com/pikvm/pikvm) project designed to stream [VGA](https://www.amazon.com/dp/B0126O0RDC) and [HDMI](https://auvidea.com/b101-hdmi-to-csi-2-bridge-15-pin-fpc/) screencast hardware data with the highest resolution and FPS possible.

-µStreamer - это маленький и очень быстрый сервер, который позволяет организовать трансляцию видео в формате [MJPEG](https://en.wikipedia.org/wiki/Motion_JPEG) с любого устройства V4L2 в сеть. Этот формат нативно поддерживается всеми современными браузерами и большинством приложений для просмотра видео (mplayer, VLC и так далее). µStreamer был разработан в рамках проекта [PiKVM](https://github.com/pikvm/pikvm) специально для стриминга с устройств видеозахвата [VGA](https://www.amazon.com/dp/B0126O0RDC) и [HDMI](https://auvidea.com/b101-hdmi-to-csi-2-bridge-15-pin-fpc/) с максимально возможным разрешением и FPS, которые только позволяет железо.
-
-Функционально µStreamer очень похож на [mjpg-streamer](https://github.com/jacksonliam/mjpg-streamer) при использовании им плагинов ```input_uvc.so``` и ```output_http.so```, однако имеет ряд серьезных отличий. Основные приведены в этой таблице:
-
-| **Фича** | **µStreamer** | **mjpg-streamer** |
-|----------|---------------|-------------------|
-| Многопоточное кодирование JPEG | ✔ | ✘ |
-| Аппаратное кодирование на Raspberry Pi | ✔ | ✘ |
-| Поведение при физическом отключении<br>устройства от сервера во время работы | ✔ Транслирует черный экран<br>с надписью ```NO SIGNAL```,<br>пока устройство не будет подключено снова | ✘ Прерывает трансляцию <sup>1</sup> |
-| Поддержка [DV-таймингов](https://linuxtv.org/downloads/v4l-dvb-apis-new/userspace-api/v4l/dv-timings.html) - возможности<br>изменения  параметров разрешения<br>трансляции на лету по сигналу<br>источника (устройства видеозахвата) | ✔ | ☹ Условно есть <sup>1</sup> |
-| Возможность пропуска фреймов при передаче<br>статического изображения по HTTP<br>для экономии трафика | ✔ <sup>2</sup> | ✘ |
-| Стрим через UNIX domain socket | ✔ | ✘ |
-| Systemd socket activation | ✔ | ✘ |
-| Дебаг-логи без перекомпиляции,<br>логгирование статистики производительности,<br>возможность получения параметров<br>трансляции по HTTP | ✔ | ✘ |
-| Возможность сервить файлы встроенным<br>HTTP-сервером  | ✔ | ☹ Нет каталогов |
-| Вывод сигналов о состоянии стрима на GPIO<br>с помощью [libgpiod](https://git.kernel.org/pub/scm/libs/libgpiod/libgpiod.git/about) | ✔ | ✘ |
-| Поддержка контролов веб-камер (фокус,<br> движение сервами) и всяких настроек,<br> типа яркости, через HTTP | ✘ | ✔ |
-| Совместимость с API mjpg-streamer'а | ✔ | :) |
-
-Сносочки:
-  * ```1``` Еще до написания µStreamer, я запилил [патч](https://github.com/jacksonliam/mjpg-streamer/pull/164), добавляющий в mjpg-streamer поддержку DV-таймингов и предотвращающий его зависание при отключении устройства. Однако патч, увы, далек от совершенства и я не гарантирую его стопроцентную работоспособность, поскольку код mjpg-streamer чрезвычайно запутан и очень плохо структурирован. Учитывая это, а также то, что в дальнейшем мне потребовались многопоточность и аппаратное кодирование JPEG, было принято решение написать свой стрим-сервер с нуля, чтобы не тратить силы на поддержку лишнего легаси.
-
-  * ```2``` Это фича позволяет в несколько раз снизить объем исходящего трафика при трансляции HDMI, однако немного увеличивает загрузку процессора. Суть в том, что HDMI - полностью цифровой интерфейс, и новый захваченный фрейм может быть идентичен предыдущему в точности до байта. В этом случае нет нужды передавать одну и ту же картинку по сети несколько раз в секунду. При использовании опции `--drop-same-frames=20`, µStreamer будет дропать все одинаковые фреймы, но не более 20 подряд. Новый фрейм сравнивается с предыдущим сначала по длине, а затем помощью ```memcmp()```.
-
-----
-# TL;DR
-Если вам нужно вещать стрим с уличной камеры и управлять ее параметрами - возьмите mjpg-streamer. Если же вам нужно очень качественное изображение с высоким FPS - µStreamer ваш бро.
-
-----
-# Сборка
-Для сборки вам понадобятся ```make```, ```gcc```, ```libevent``` с поддержкой ```pthreads```, ```libjpeg8```/```libjpeg-turbo``` и ```libbsd``` (только для Linux).
-
-* Arch: `sudo pacman -S libevent libjpeg-turbo libutil-linux libbsd`.
-* Raspbian: `sudo apt install libevent-dev libjpeg8-dev libbsd-dev`.  Добавьте `libgpiod` для `WITH_GPIO=1` и `libsystemd-dev` для `WITH_SYSTEMD=1`.
-* Debian/Ubuntu: `sudo apt install build-essential libevent-dev libjpeg-dev libbsd-dev`.
-
-Для включения сборки с поддержкой GPIO установите [libgpiod](https://git.kernel.org/pub/scm/libs/libgpiod/libgpiod.git/about) и добавьте параметр ```WITH_GPIO=1```. Если при сборке компилятор ругается на отсутствие функции ```pthread_get_name_np()``` или другой подобной, добавьте параметр ```WITH_PTHREAD_NP=0``` (по умолчанию он включен). При аналогичной ошибке с функцией ```setproctitle()``` добавьте параметр ```WITH_SETPROCTITLE=0```.

-----
-# Использование
-**Для аппаратного кодирования M2M на Raspberry Pi, вам нужно ядро минимальной версии 5.15.32. Поддержка OpenMAX и MMAL для более старых ядер объявлена устаревшей и была удалена.**
-
-Будучи запущенным без аргументов, ```ustreamer``` попробует открыть устройство ```/dev/video0``` с разрешением 640x480 и начать трансляцию на ```http://127.0.0.1:8080```. Это поведение может быть изменено с помощью опций ```--device```, ```--host``` и ```--port```. Пример вещания на всю сеть по 80-м порту:
-```
-# ./ustreamer --device=/dev/video1 --host=0.0.0.0 --port=80
-```
-
-:exclamation: Обратите внимание, что начиная с версии µStreamer v2.0 кросс-доменные запросы были выключены по умолчанию [по соображениям безопасности](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS). Чтобы включить старое поведение, используйте опцию `--allow-origin=\*`.
-
-Рекомендуемый способ запуска µStreamer для работы с [Auvidea B101](https://www.raspberrypi.org/forums/viewtopic.php?f=38&t=120702&start=400#p1339178) на Raspberry Pi:
-```bash
-$ ./ustreamer \
-    --format=uyvy \ # Настройка входного формата устройства
-    --encoder=m2m-image \ # Аппаратное кодирование с помощью драйвера V4L2 M2M
-    --workers=3 \ # Максимум воркеров
-    --persistent \ # Не переинициализировать устройство при таймауте (например, когда был отключен HDMI-кабель)
-    --dv-timings \ # Включение DV-таймингов
-    --drop-same-frames=30 # Экономим трафик
-```
-
-:exclamation: Обратите внимание, что для использования `--drop-same-frames` для разных браузеров нужно использовать ряд специальных параметров в `/stream` (за деталями обратитесь к урлу `/`).
-
-За полным списком опций обращайтесь ко встроенной справке: ```ustreamer --help```.
-
-----
-# Камера Raspberry Pi
-Пример использования камеры Raspberry Pi v1:
-```bash
-$ sudo modprobe bcm2835-v4l2
-$ ./ustreamer --host :: -m jpeg --device-timeout=5 --buffers=3 -r 2592x1944
-```
-
-:exclamation: Обратите внимание что боле новые модели камеры имеют другое максимальное разрешение. Список поддерживаемых разрешений можно найти в [документации PiCamera](https://picamera.readthedocs.io/en/release-1.13/fov.html#sensor-modes).
-
-:exclamation: Если камера выдает низкий фреймрейт, возможно что она работает в фото-режиме, где производит более низкий фпс, но более качественную кратинку. Это происходит потому что `bcm2835-v4l2` переключает камеру в фото-режим на разрешениях выше `1280x720`. Чтобы обойти это, передайте параметры `max_video_width` и `max_video_height` при загрузке модуля, например:
-
-```bash
-$ modprobe bcm2835-v4l2 max_video_width=2592 max_video_height=1944
-```
-
-----
-# Интеграция
-
-## Nginx
-Если uStreamer находится на Nginx, то последний будет буферизировать поток и создавать дополнительную задержку в стриме. Чтобы задержки не было, буферизацию можно отключить:
-
-```nginx
-location /stream {
-    postpone_output 0;
-    proxy_buffering off;
-    proxy_ignore_headers X-Accel-Buffering;
-    proxy_pass http://ustreamer;
-}
-```
-
-----
-# Утилиты V4L2
-V4L2 предоставляет ряд официальных утилит для управления USB-вебкамерами и получения информации об устройствах. С их помощью можно писать всякие настроечные скрипты и запускать их по крону, если, например, вам требуется изменять настройки экспозиции в зависимости от времени суток. Пакет с этими утилитами доступен на всех дистрибутивах Linux и обычно называется `v4l-utils`.
-
-* Вывести список видеоустройств: `v4l2-ctl --list-devices`.
-* Вывести список доступных контролов устройства: `v4l2-ctl -d /dev/video0 --list-ctrls`.
-* Вывести список доступных форматов видео: `v4l2-ctl -d /dev/video0 --list-formats-ext`.
-* Показать текущее значение контрола: `v4l2-ctl -d /dev/video0 --get-ctrl=exposure_auto`.
-* Изменить значение контрола: `v4l2-ctl -d /dev/video0 --set-ctrl=exposure_auto=1`.
-
-Больше примеров вы можете найти [здесь](https://www.kurokesu.com/main/2016/01/16/manual-usb-camera-settings-in-linux/), а документацию в [`man v4l2-ctl`](https://www.mankier.com/1/v4l2-ctl).
