# µStreamer
|
||||
[[Русская версия]](README.ru.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.
|
||||
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.
|
||||
|
||||
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:
|
||||
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:

Сносочки:
|

* ```1``` Для mjpg-streamer существует [мой патч](https://github.com/jacksonliam/mjpg-streamer/pull/164), предотвращающий зависание при отключении устройства и добавляющий поддержку DV-таймингов, однако трансляция при этом все равно прерывается. В данный момент этот патч не принят в апстрим, и я даже не гарантирую его стопроцентную работоспособность. Код mjpg-streamer очень плохо структурирован и чрезвычайно запутан, и я мог что-то упустить. Собственно, это одна из причин, почему µStreamer написан с нуля.
|
||||
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``` Это фича позволяет в несколько раз снизить объем исходящего трафика при трансляции HDMI, однако увеличивает загрузку процессора и добавляет небольшую задержку. 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. Новый фрейм сравнивается с предыдущим сначала по длине, а затем помощью ```memcmp()```.
|
||||
* ```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``` Поскольку µStreamer писался в первую очередь для устройств видеозахвата, в нем реализованы только те форматы, которые для них были нужны. MJPG в контексте входных данных означает, что устройство умеет самостоятельно сжимать картинку в JPEG и отдавать ее программе, что позволяет значительно снизить загрузку процессора и избавить его от необходимости кодировать картинку софтом. Этот формат поддерживается большинством веб-камер, но не поддерживается ни одним из встреченных мной устройств видеозахвата; его не умеет ни [Auvidea B101](https://auvidea.com/b101-hdmi-to-csi-2-bridge-15-pin-fpc/), ни [EasyCap UTV 007](https://www.amazon.com/dp/B0126O0RDC). Нет никаких технических сложностей добавить поддержку аппаратного MJPG источника, но у меня просто пока не дошли до этого руки.
|
||||
* ```3``` As µStreamer was made mainly to be used with screencast hardware it supports video formats they usually need. MJPG input means that the screencast device can compress images to JPEG and feed it to the software, which allows to cut down CPU usage and avoid software image encoding. This video format is supported by most webcams, but I've never seen it supported by screencast hardware: neither [Auvidea B101](https://auvidea.com/b101-hdmi-to-csi-2-bridge-15-pin-fpc/), nor [EasyCap UTV 007](https://www.amazon.com/dp/B0126O0RDC) offer such support. It's not hard to add hardware MJPG sources support, it's just not done yet.
|
||||
|
||||
* ```4``` ... и не будет. µStreamer придерживается концепции UNIX-way, так что если вам нужно нарисовать маленький сайтик со встроенной трансляцией - просто поставьте NGINX.
|
||||
* ```4``` ...and there'll never be. µStreamer is designed UNIX-way, so if you need a small website with your broadcast, install 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.
|
||||
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```.

# Usage
|
||||
Without arguments, ```ustreamer``` will try to open ```/dev/video0``` with 640x480 resolution and start broadcasting on ```http://localhost: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
