Example tutorial

    We have carefully produced a wealth of sample tutorials, covering audio and video input and output, audio and video codec, screenshots, streaming, recording, video mixing, special effects overlay, USB camera, GPIO operation, power management, touch screen operation, OLED screen control, etc. Links to help you remove all the problems that may be encountered in the product development process. We will continue to update sample projects and tutorials.

LinkSVP

    In order to facilitate users to develop products in the field of machine vision and AI, we have developed the LinkSVP framework to simplify the upstream and downstream development process and allow developers to focus on core algorithms. At the same time, several sample programs have been made to help users easily get started. Even in the scheme with NNIE unit, we provide tools for the acceleration of embedded optimization and can also run deep learning algorithms.

Development environment

    We have cross-compiled common third-party libraries and placed them in the virtual machine to facilitate user development and use.

  • Development framework: QT5
  • Media related: ffmpeg, fdkaac, lame, alsa
  • WEB development: php, nginx (nginx-rtmp+http-flv)
  • Network related: iperf, ppp, wpa, hostap, iw, libnl, ssl
  • Graphics processing: Opencv, NCNN
  • Others: freetype, icu, libts, zlib, libxml...
  • Open source software

    In order to demonstrate the basic capabilities of the evaluation board so that users can fully evaluate the solution before starting to develop it, we have produced an "encoder system" that demonstrates all the interface capabilities and codec performance of the solution in the form of a universal encoder. The product is completely open source, including main program source code, file system, webpage source code, etc.
    If the user's target product is similar to the open source product, it can be modified directly on the basis of the product source code.
