## Preparation
#### Install Rust and Cargo

[Document](https://doc.rust-lang.org/cargo/getting-started/installation.html)

## Install and run

There are two ways to install xiu :

 - Using cargo to install
 - Building from source


### Install using cargo

Issue the following command to install xiu:

    cargo install xiu
Start the service with the following command to get help:

    xiu -h
    A secure and easy to use live media server, hope you love it!!!

    Usage: xiu [OPTIONS]

    Options:
      -c, --config <path>   Specify the xiu server configuration file path.
      -r, --rtmp <port>     Specify the RTMP listening port(e.g.:1935).
      -t, --rtsp <port>     Specify the rtsp listening port.(e.g.:554).
      -w, --webrtc <port>   Specify the whip/whep listening port.(e.g.:8900).
      -f, --httpflv <port>  Specify the HTTP-FLV listening port(e.g.:8080).
      -s, --hls <port>      Specify the HLS listening port(e.g.:8081).
      -l, --log <level>     Specify the log level. [possible values: trace, debug, info, warn, error, debug]
      -h, --help            Print help.
      -V, --version         Print version.

### Build from souce

#### Clone Xiu

    git clone https://github.com/harlanc/xiu.git

use master branch

#### Build

We use makefile to build xiu and revelant libraries.

- Using make local to build local source codes:

        make local && make build
- Using make online to pull the online crates codes and build:

        make online && make build

#### Run

    cd ./xiu/target/release or ./xiu/target/debug
    ./xiu -h

## CLI

#### Instructions

You can use command line to configure the xiu server easily. You can specify to configure xiu using configuration file or from the command lines.

##### Configure using file

    xiu -c configuration_file_path

##### Configure using command line

    xiu -r 1935 -t 5544 -f 8080 -s 8081 -l info


#### How to Configure the configuration file

##### RTMP
    [rtmp]
    enabled = true
    port = 1935

    # pull streams from other server node.
    [rtmp.pull]
    enabled = false
    address = "192.168.0.1"
    port = 1935

    # push streams to other server node.
    [[rtmp.push]]
    enabled = true
    address = "localhost"
    port = 1936
    [[rtmp.push]]
    enabled = true
    address = "192.168.0.3"
    port = 1935


##### RTSP
    [rtsp]
    enabled = false
    port = 5544

##### WebRTC(Whip/Whep)
    [webrtc]
    enabled = false
    port = 8900

##### HTTPFLV

    [httpflv]
    # true or false to enable or disable the feature
    enabled = true
    # listening port
    port = 8081

##### HLS
    [hls]
    # true or false to enable or disable the feature
    enabled = true
    # listening port
    port = 8080
    # need record the live stream or not
    need_record = true

##### Log

    [log]
    level = "info"
    [log.file]
    # write log to file or not（Writing logs to file or console cannot be satisfied at the same time）.
    enabled = true
    # set the rotate
    rotate = "hour" #[day,hour,minute]
    # set the path where the logs are saved
    path = "./logs"

### Configuration examples

I edit some configuration files under the following path which can be used directly:

    xiu/application/xiu/src/config

It contains the following 4 files:

    config_rtmp.toml //enable rtmp only
    config_rtmp_hls.toml //enable rtmp and hls
    config_rtmp_httpflv.toml //enable rtmp and httpflv
    config_rtmp_httpflv_hls.toml //enable all the 3 protocols


## Scenarios

##### Push

###### Push RTMP

You can use two ways:

- Use OBS to push a live rtmp stream
- Or use FFmpeg to push a rtmp stream:

        ffmpeg -re -stream_loop -1 -i test.mp4 -c:a copy -c:v copy -f flv -flvflags no_duration_filesize rtmp://127.0.0.1:1935/live/test

###### Push RTSP

- Over TCP(Interleaved mode)

        ffmpeg -re -stream_loop -1  -i test.mp4 -c:v copy  -c:a copy  -rtsp_transport tcp   -f rtsp rtsp://127.0.0.1:5544/live/test

- Over UDP

        ffmpeg -re -stream_loop -1  -i test.mp4 -c:v copy  -c:a copy     -f rtsp rtsp://127.0.0.1:5544/live/test

###### Push RTC(Whip)

Now OBS (version 3.0 or above) can support whip output. The configurations are as follows:

##### Play

Use ffplay to play the rtmp/rtsp/httpflv/hls live stream:

    ffplay -i rtmp://localhost:1935/live/test
    ffplay -i rtsp://127.0.0.1:5544/live/test
    ffplay -rtsp_transport tcp -i rtsp://127.0.0.1:5544/live/test
    ffplay -i http://localhost:8081/live/test.flv
    ffplay -i http://localhost:8080/live/test/test.m3u8

- How to play WebRTC stream*(Whep)

  1. Copy the files under xiu/protocol/webrtc/src/clients/ folder to the same level directory of the binary file xiu.
  2. Open the address http://localhost:8900 in the browser.
  3. Enter the app name and stream name corresponding to the OBS whip publish address.
  4. Click Start WHEP(After OBS publish) to play the RTC stream.

##### Relay - Static push

The configuration files are as follows:

The configuration file of Service 1 named config.toml:

    [rtmp]
    enabled = true
    port = 1935
    [[rtmp.push]]
    enabled = true
    address = "localhost"
    port = 1936

The configuration file of Service 2 named config_push.toml:

    [rtmp]
    enabled = true
    port = 1936

Run the 2 services:

    ./xiu config.toml
    ./xiu config_push.toml


Use the above methods to push rtmp live stream to service 1, then the stream can be pushed to service 2 automatically, you can play the same live stream from both the two services:

    ffplay -i rtmp://localhost:1935/live/test
    ffplay -i rtmp://localhost:1936/live/test


##### Relay - Static pull

The configuration file are as follows:

The configuration file of Service 1 named config.toml:

    [rtmp]
    enabled = true
    port = 1935


The configuration file of Service 2 named config_pull.toml:

    [rtmp]
    enabled = true
    port = 1936
    [rtmp.pull]
    enabled = false
    address = "localhost"
    port = 1935

Run the 2 services:

    ./xiu config.toml
    ./xiu config_pull.toml

Use the above methods to push live stream to service 1, when you play the stream from serivce 2, it will pull the stream from service 1:

    ffplay -i rtmp://localhost:1935/live/test
    ffplay -i rtmp://localhost:1936/live/test
