Download and Build

Prebuilt Image

For fast begin, you can download the [prebuilt image here.
国内开发者请在此下载提取码：4p3h

System 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

Lazy Start

Here are VMware station 14 image files which include the whole compiled SDK. And the SDK remote repositoreies are on gitee (not github).
Click here to get it (access code: tq4x)
The password of the Ubuntu 14.04 in the VMware is "lindenis". Enjoy it !

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):

Ctrl-X to leave, save your changes, and you're done!

Downloading

The SDK is available on github. For Chinese developer, it is available on gitee too.

We use Repo manage Git repositories. Clone Repo from android Git repositories or other mirrors and install it.
Chinese developers can install Repo follow these steps: 

$ git clone http://mirrors.ustc.edu.cn/aosp/git-repo.git ~/.bin/repo
$ echo "export PATH=~/.bin/repo:$PATH" >> ~/.bashrc
$ source ~/.bashrc

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 V536 SBC, download the SDK on Github via:(此为github的下载方式，国内下载较慢，请使用国内源的方式下载，见下文)

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
Lindplayer

lindplayer is a high performance media player that can run on lindenis board. It supports upto 4K@30fps H.264/H.265 video decoder. It can play a local media file or a media stream from internet.

usage: 

   lindplayer -u [url] <options>
       -u [url] is the media path to be played.
       <options> use -live to indicate this is a live streaming.
   such as:
       lindplayer -u ./movie.ts
   or  lindplayer -u http://192.168.1.102/test
   or  lindplayer -u rtsp://192.168.1.102/test -live
