# µStreamer
[[Русская версия]](README.ru.md)
µStreamer is a lightweight and very quick server to broadcast [MJPG](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 [Pi-KVM](https://github.com/pi-kvm) 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 is very similar to [mjpg-streamer](https://github.com/jacksonliam/mjpg-streamer) with ```input_uvc.so``` and ```output_http.so``` plugins, however, there are some major differences. The key ones are:
| **Feature** | **µStreamer** | **mjpg-streamer** |

Footnotes:
* ```1``` Long before µStreamer, I made a [patch](https://github.com/jacksonliam/mjpg-streamer/pull/164) to add DV-timings support to mjpg-streamer and to keep it from hanging up no device disconnection. Alas, the patch is far from perfect and I can't guarantee it will work every time - mjpg-streamer's source code is very complicated and its structure is hard to understand. With this in mind, along with needing multithreading and JPEG hardware acceleration in the future, I decided to make my own stream server from scratch instead of supporting legacy code.
* ```2``` This feature allows to cut down outgoing traffic several-fold when broadcasting HDMI, but it increases CPU usage a little bit. The idea is that HDMI is a fully digital interface and each captured frame can be identical to the previous one byte-wise. There's no need to broadcast the same image over the net several times a second. With the `--drop-same-frames=20` option enabled, µStreamer will drop all the matching frames (with a limit of 20 in a row). Each new frame is matched with the previous one first by length, then using ```memcmp()```.
* ```3``` ...and there'll never be. µStreamer is designed UNIX-way, so if you need a small website with your broadcast, install NGINX.
-----
# TL;DR
If you're going to live-stream from your backyard webcam and need to control it, use mjpg-streamer. If you need a high-quality image with high FPS - µStreamer for the win.
-----
# Building
You'll need ```make```, ```gcc```, ```libevent``` with ```pthreads``` support, ```libjpeg8```/```libjpeg-turbo``` and ```libuuid```.
It should compile automatically with OpenMAX IL on Raspberry Pi, if the corresponding headers are present in ```/opt/vc/include```.
```
$ git clone --depth=1 https://github.com/pi-kvm/ustreamer
$ cd ustreamer
$ make
$ ./ustreamer --help
```
AUR has a package for Arch Linux: https://aur.archlinux.org/packages/ustreamer
-----
# Usage
Without arguments, ```ustreamer``` will try to open ```/dev/video0``` with 640x480 resolution and start broadcasting on ```http://127.0.0.1:8080```. You can override this behavior using parameters ```--device```, ```--host``` and ```--port```. For example, to broadcast to the world, run:
```
# ./ustreamer --device=/dev/video1 --host=0.0.0.0 --port=80
```
The recommended way of running µStreamer with [Auvidea B101](https://www.raspberrypi.org/forums/viewtopic.php?f=38&t=120702&start=400#p1339178) on Raspberry Pi:
```bash
$ ./ustreamer \
--format=uyvy \ # Device input format
--encoder=omx \ # Hardware encoding with OpenMAX
--workers=3 \ # Maximum workers for OpenMAX
--persistent \ # Don't re-initialize device on timeout (for example when HDMI cable was disconnected)
--dv-timings \ # Use DV-timings
--drop-same-frames=30 # Save that traffic
```
You can always view the full list of options with ```ustreamer --help```.

# µStreamer
[[English version]](README.md)
µStreamer - это маленький и очень быстрый сервер, который позволяет организовать трансляцию видео в формате [MJPG](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 [Pi-KVM](https://github.com/pi-kvm) 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:

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()```.
* ```3``` ... и не будет. µStreamer придерживается концепции UNIX-way, так что если вам нужно нарисовать маленький сайтик со встроенной трансляцией - просто поставьте NGINX.
-----
# 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 ```libuuid```.
На Raspberry Pi програма автоматически собирается с поддержкой OpenMAX IL, если обнаружит нужные хедеры в ```/opt/vc/include```.
```
$ git clone --depth=1 https://github.com/pi-kvm/ustreamer
$ cd ustreamer
$ make
$ ./ustreamer --help
```
Для Arch Linux в AUR есть готовый пакет: https://aur.archlinux.org/packages/ustreamer
-----
# Использование
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
```
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=omx \ # Использование аппаратного кодирования с помощью OpenMAX
--workers=3 \ # Максимум воркеров для OpenMAX
--persistent \ # Не переинициализировать устройство при таймауте (например, когда был отключен HDMI-кабель)
--dv-timings \ # Включение DV-таймингов
--drop-same-frames=30 # Экономим трафик
```
За полным списком опций обращайтесь ко встроенной справке: ```ustreamer --help```.
