    Sample tutorial

    Our team crafted a rich example of tutorials, they include the audio input and output, audio decoding, screenshots, streaming, recording, video mixing, special effects, USB camera, GPIO operation, power management, touch screen operation, OLED screen control example program, to help you solve to death to all the problems in the process of product development, and we also constantly update example libraries and tutorial content.

    LinkSVP

    To make it easier for customers to develop products in machine vision and AI, we developed the LinkSVP framework, which simplifies the application development process so developers can focus more on the core algorithm, and we created several sample programs to help users quickly use it.Even on solutions with NNIE units, we can run deep learning algorithms by providing acceleration tools for embedded optimization

    Development environment

    We have cross-compiled common third-party libraries and placed them in virtual machines for easy development and debugging.

    Open source code description

    In order to demonstrate the basic capabilities of the evaluation board and make it easy for users to fully evaluate the program before using the development program, we have developed an “encoder system” that can display all the interfaces of the customized development program and its encoding and decoding capabilities through the form of a visual and audio encoder.The product is completely open source, including the main program source code, file system, web source code and so on.

    If the user’s target product is similar to the open source product, it can be modified directly from the source code of the product.

    Open source function
    Running status

    -CPU performance, memory footprint, network status

    -Interface state, resolution detection

    Encoding setting

    Encoding format – h. 264, h. 265,ACC,MP3,PCMA

    Resolution – 3840 x2160, 1920 x1080, 1280 x720, 640 x360

    Others – bit rate control, key frame interval, audio channel

    Note – all properties support dynamic modification and take effect in real time, no need to restart the device

    Output Settings

    Support the transport protocol – RTSP, RTMP, HLS, HTTP, ONVIF, unicast, multicast, pushing streams

    Others

    Network input – standard stream input is supported and can be streamed or recoded directly

    Overlay effects – captions, rolling captions, watermarks, tabletops, mosaics

    Screen mixed audio and video – multiple screen arbitrary layout Mosaic combination, and can be codec output, similar to the broadcast function Computer room monitoring: the camera is inserted through the USB port, which can encode and output live screen for monitoring the situation of the computer room. Meanwhile, it supports the dynamic alarm function.

    File recording – after the encoder is inserted into the usb flash disk, it can record the channel live stream into the file format and then save it to the usb flash disk.

    Video rotation – looping the video files on the usb flash drive and generating a live video stream.

    Group control – all video encoders can automatically group, and they can realize automatic device discovery, IP configuration, program summary and other functions. Any device in the LAN can serve as a media publishing server to provide concurrent live streaming.
