算法盒子接入

2026年 5月 20日下午3:36

## 简介
NodeMediaServer支持算法盒子推理后再编码推流，本例以算能设备举例

## NMS配置
确保rtsp 的端口项设置
```ini
[rtsp]
# port rtsp协议tcp端口, ffmpeg,vlc等播放器默认使用tcp传输协议,udp传输rtp媒体数据
# ffmpeg 使用 -rtsp_transport tcp 则rtsp协议和rtp数据都通过单一tcp端口传输
# vlc 使用命令行加参数设置tcp传输  /usr/bin/vlc --rtsp-tcp rtsp://localhost/live/2
# 使用tcp传输的好处是 1:单一网络端口开放, 2:公网传输不花屏
# 对应播放和推流地址规范与rtmp一样, 也支持鉴权参数
# rtsp://localhost/live/stream
# rtsp://localhost/live/stream?sign=1671694080-64669b5d4b147ac09dc6ec42ef79815d
# 支持h264/h265+aac/opus/g.711 编码
port      = 8554
# RTP port , RTP通过UDP传输时,复用该端口, 该端口必须是偶数
rtp_port  = 8002
# RTCP port, RTCP通过UDP传输时,复用该端口, 该端口比RTP_PORT大1
rtcp_port = 8003

```

请确认版本更新到2025/04/01之后的版本，已提交兼容补丁

### RTSP推流
```json
{
  "configure": {
    "encode_type": "RTSP",
    "rtsp_port": "8554",
    "rtmp_port": "1935",
    "ip":"192.168.2.222",
    "prefix":"sophon_",
    "wss_port": "9000",
    "enc_fmt": "h264_bm",
    "pix_fmt": "I420",
    "ws_enc_type": "IMG_ONLY",
    "fps": 25
  },
  "shared_object": "../../build/lib/libencode.so",
  "name": "encode",
  "side": "sophgo",
  "thread_number": 4
}

```

### RTMP推流
```json
{
  "configure": {
    "encode_type": "RTMP",
    "rtsp_port": "8554",
    "rtmp_port": "1935",
    "ip":"192.168.2.222",
    "prefix":"sophon_",
    "wss_port": "9000",
    "enc_fmt": "h265_bm",
    "pix_fmt": "I420",
    "ws_enc_type": "IMG_ONLY",
    "fps": 25
  },
  "shared_object": "../../build/lib/libencode.so",
  "name": "encode",
  "side": "sophgo",
  "thread_number": 4
}

```

### 编码兼容
RTMP、RTSP协议推流都支持h264/h265编码
如需要H265编码确保已设置
```
    "enc_fmt": "h265_bm",
```
