  • Memory: 8GB or higher
  • Disk: 10GB free hard disk space
  • 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 dpkg --add-architecture i386
$ sudo apt-get update
$ sudo apt-get install git git-core u-boot-tools qemu qemu-user-static debootstrap lib32z1 lib32ncurses5 libc6:i386 libstdc++6:i386 gawk

Sudo without password 

$ sudo visudo

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

tom ALL=(ALL) NOPASSWD: ALL

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

Downloading

The SDK is available on github.

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

For Lindenis V536 SBC, download the SDK via: 

$ repo init -u https://github.com/lindenis-org/manifest.git -b v536 -m lindenis-v536.xml
$ repo sync

The Download time depends on your network connection speed. After finish the download, you should get below directories and files: 

build  config  Config.in  device  dl  lichee  Makefile  package  prebuilt  rules.mk  scripts  softwinner  target  toolchain  tools

Start a branch for local workspace: 

$ repo start lindenis-v536 --all

Application Demo

The application demos powered by Lindenis.

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
