Description
The EV3 is a professional 1-channel HDMI H.265 hardware codec and 4K30 video encoder mainboard, designed for high-quality video encoding, decoding, and IP transcoding applications. It features 1 channel of HDMI output and supports H.265 Main Profile and H.264 encoding standards (ITU-T and ISO international video coding standards), delivering broadcast-grade video quality in a compact embedded form factor.
The EV3 can simultaneously encode 1 channel of 4K 30fps H.265 video with stereo audio. It also functions as a 1-channel decoder and can be converted into a 1-channel IP transcoder, making it highly flexible for a wide range of deployment scenarios. Compared with widely used H.264 solutions, it reduces transmission bandwidth and storage space by 30–50% at the same video quality, significantly lowering operating costs for operators and enterprises.
SS524 supported audio encoding formats are AAC, MP3, PCMA,MPEG-2 etc, Support live stream protocol NDI,SRT,NDI,HTTP, HLS, RTSP, RTMPE,RTMP of flow push, RTMP pull flow, UDP, Multicast network protocol etc. And the one same channel can enable all network streams at the same time.
EV3 provide the Sample program and PQTools.

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

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 -Video preview |
| 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. |
