Description
About video and audio hardware transcoding technology description
1. When we are streaming live video and audio over the Internet, in the IPTV solution, HI3531D hevc hardware transcoder development board can receive external (for example: live stream from a surveillance camera RTSP ://192.168.0.68:9988) h 265,h 264 live streaming, after HI3531D hardware chip decoding, the working process of secondary coding through the chip is called hardware decoding and coding. Usually the industry calls this process transcoding(such as h 265 to h 264 video converter, or made to file that you want).
HI3531D SDI h265 h264 hevc encoder mainboard which is studied, developed and manufactured independently by JLONvision is a 2 channel of 4K 30fps or 8 channel 1080P 60fps embedded video and audio hardware encoder, also is a 4 channel SDI 1080P 60fps encoder development board. It supports video and audio encoding function, It supports 1 channel 4K HDMI output mixed screen, 1 channel HDMI1080P quality video decoding output, Or with VGA output. It applies H265 and H264 encoding standard (this standard is a digital video encoding standard made out by TTU-T and ISO). With this encoding standard,it can encode 2 channels of 4K H265 video and stereo audio simultaneously. It is inserted with DE-interlacing scanning algorithm, which makes video quality reach the best level. Compared with the present widely used H264 encoding algorithm, HI3531D SDI h265 h264 hevc encoder mainboard can save 30-50% of transmission bandwidth and storage space at the same video quality.
HI3531D SDI h265 h264 hevc encoder mainboard and hevc hardware transcoder development board main chip powerful and provide rich interface, we provide you with a development tool, free SDK and technical support.
HI3531D hevc hardware transcoder development board Supported audio encoding formats are AAC,MP3, PCMA, etc, Support live stream protocol HTTP, HLS, RTSP, 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.
HI3531D hevc hardware transcoder development board has video and audio coding capabilities,and it supports 2-8 channel video live streaming transcoder,So it has two powerful video and audio processing capabilities(As shown in figure 1.1,1.2).

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. |
