LinkPi encoding system is a opensource product independently developed by Guangzhou Lingpai Technology Co., Ltd. This series of products have the advantages of low power consumption and high reliability, and support 7x24 hours of uninterrupted work. It can be widely used in network live broadcast, IPTV system, wireless image transmission, teaching recording and broadcasting, video conference, monitoring and other fields. In addition to the basic encoding and streaming functions of traditional encoders, the system also supports special effects editing, directing, network decoding, file recording, and video carousel. And, relying on the increasingly powerful LinkSDK system, the function of the product continues to grow.
Specification
ENC1 high-definition encoder supports 4K @ 30 input, which is mainly used for embedded hardware devices for high-definition video and audio signal encoding and network transmission. ENC1 has built-in self-developed full frame rate de-interlacing technology (such as 1080i @ 60 input, 1080p @ 60 after de-interlacing, not 1080P @ 30, which is especially important for football live and game live).
ENC1 supports video encoding format H264 And H265, the supported audio encoding formats are AAC, MP3, PCMA, etc. ENC1 supports HTTP, HLS, RTSP, RTMP push streaming, RTMP pull streaming, UDP, Multicast and other network protocols, and all network streams can be enabled at the same time on the same channel.
ENC1 supports foreign network streaming and local video and audio files (such as U disk) for transcoding and streaming.
ENC1 supports USB UVC cameras. In the future, external USB UVC cameras can be added for encoding, storage and live broadcasting.
ENC1 supports multi-input source splicing output (such as 9-square grid, 2 + 1 picture, picture-in-picture, etc.).
ENC1 uses Huawei's HiSilicon chip: Hi3531D.
