SDK

Host PC requirements

Listed below are the recommended requirements for downloading and building the SDK:

• CPU: x86_64 or better family processor
• Memory: 8GB or higher
• Disk: 20GB free hard disk space, if you build it in a Virtual machine, I recommand you allocate a 30G virtual hard disk.
  • The Whole SDK is about 15G.
• OS: Ubuntu 14.04 (tested) or higher
• Network: internet connection

Linux host setup

Ubuntu 14.04

HINT: later version should also work.

Install prerequisites

$ sudo apt-get update
$ sudo apt-get install build-essential libncurses5-dev zlib1g-dev gawk git git-core ccache gettext libssl-dev xsltproc gperf subversion 
$ sudo dpkg --add-architecture i386
$ sudo apt-get update
$ sudo apt-get install lib32z1 lib32ncurses5 libc6:i386 libstdc++6:i386

Sudo without password

$ sudo visudo

Add this line at the end (change “tom” to your username):

tom ALL=(ALL) NOPASSWD: ALL

Download and Build

Prebuilt Image

For fast begin, you can download the prebuilt image here. Click me
国内开发者请在此下载提取码：v833

SDK Source Code Downloading

The SDK is available on github. For Chinese developer, it is available on gitee too.
由于国内从Github上下载速度较慢，建议从Gitee上下载 --> Gitee下载说明

We use Repo manage Git repositories. Clone Repo from android Git repositories or other mirrors and install it. Becase there are some big files in the SDK, please run the following command before you start the downloading.

$ git config --global http.postBuffer 524288000

Then run this to check:

$ git config --list

For Lindenis V833 SBC, download the SDK on Github via:

$ mkdir v833-lindenis
$ cd v833-lindenis
$ repo init -u https://github.com/lindenis-org/manifest.git -b v833 -m v833-lindenis.xml
$ repo sync

And then download the listing files from cloud disk with access phrase v833. Click me then enter "v833"
If the link is invaild, please send e-mail to tell us. Here is the e-mail address: services@lindeni.com

1. dl.tar.gz
2. gcc-linaro-7.2.1-2017.11-x86_64_arm-linux-gnueabi.tar.xz

Lindenis Application Demo

Lindlive

lindlive is a high performance low latency live streaming library. lindlive integrate some useful function modules, such as audio/video capture, encoding and streaming protocol. So developers can easily implement a live streaming server based on lindenis board.

There are two samples app using lindlive, one is sample_mppsrc_2_livesink and the other is sample_mppsrc_2_ffsink. The sample source code is located in SDK.

!!! It is strongly recommended to use lindplayer with '-live' as the client of the lindlive. It will be lower latency.

usage:

   sample_mppsrc_2_livesink -i [ip] -p [port] -n [name]
       -i [ip] is the ip address of the server. If it is not set, the 'ip' default is local ethernet or wifi ip address.
       -p [port] is the port of the server. If it is not set, the 'port' default is rtsp port 8554.
       -n [name] is the name of live streaming. If it is not set, the 'name' default is 'live'.
       All of the arguments are optional.
   If sample_mppsrc_2_livesink is correctly running, the server url is 'rtsp://[ip]:[port]/[name]'
   Then it can be played in an player with the url 'rtsp://[ip]:[port]/[name]'.

   sample_mppsrc_2_ffsink -t [type] -u [url]
       -t [type]: the muxer type, can be 'mpegts/mp4/rtp/rtp_mpegts/rtsp/rtmp'
       -u [url] : sink to url, like: '/tmp/out.mp4' or 'rtp://192.168.1.100:12345'
   Example 1: sink as a live streaming.
       sample_mppsrc_2_ffsink -t rtp_mpegts -u rtp://192.168.3.118:12345
       sample_mppsrc_2_ffsink -t rtp -u rtp://192.168.3.118:12342/test
       Then it can be played in an player with the url 'rtsp://[ip]:[port]/[name]'.
   Example 2: save as a local file.
       sample_mppsrc_2_ffsink -t mp4 -u /tmp/out.mp4
       sample_mppsrc_2_ffsink -t mpegts -u /tmp/out.ts

msh /> wifi -o 0              -- wifi on and work on station mode
msh /> wifi -s                -- scan the existing AP SSID
msh /> wifi -c SSID PASSWD    -- connect to AP, whose ID is SSID, with PASSWD
msh /> netif_ifconfig         -- to get the network information
msh /> ping www.baidu.com     -- ping website to check it works well or not
msh /> wifi -f                -- wifi off
