设置 RTSP - Qualcomm Dragonwing Documentation

下载 MediaMTX 工具以搭建 RTSP 监听服务器。以下步骤已针对 MediaMTX 版本 v1.11.3_linux_arm64v8 验证，可从 mediamtx_v1.11.3_linux_arm64v8.tar.gz 获取。

解压下载的归档文件，并编辑 mediamtx.yml 文件以在端口 8901 上启用 RTSP 流。

# Global settings -> RTSP server

# Enable publishing and reading streams with the RTSP protocol.
rtsp: yes

# List of enabled RTSP transport protocols.
# UDP is the most performant, but doesn't work when there's a NAT/firewall between
# server and clients, and doesn't support encryption.
# UDP-multicast allows to save bandwidth when clients are all in the same LAN.
# TCP is the most versatile, and does support encryption.
# The handshake is always performed with TCP.
rtspTransports: [udp, multicast, tcp]

# Encrypt handshakes and TCP streams with TLS (RTSPS).
# Available values are "no", "strict", "optional".
rtspEncryption: "no"

# Address of the TCP/RTSP listener. This is needed only when encryption is "no" or "optional".
rtspAddress: :8901

# Address of the TCP/TLS/RTSPS listener. This is needed only when encryption is "strict" or "optional".
rtspsAddress: :8322

将 mediamtx.yml 文件和 mediamtx 可执行文件复制到设备：

scp -P 2222 -o StrictHostKeychecking=no -o UserKnownHostsFile=/dev/null <mediamtx path>/mediamtx root@localhost:/opt

scp -P 2222 -o StrictHostKeychecking=no -o UserKnownHostsFile=/dev/null <mediamtx path>/mediamtx.yml root@localhost:/opt

打开新的 SSH shell 并运行 mediamtx 工具：
cd /opt chmod +x mediamtx ./mediamtx
在主机上的 localhost 端口 8901 上启动 RTSP 流。以下示例使用 FFmpeg 从连接的网络摄像头捕获输入并将其作为 RTSP 流发送。如果未安装 FFmpeg，请从 FFmpeg 网站下载。
ffmpeg -f dshow -video_size 640x480 -i video="Integrated Camera" -framerate 15 -vf format=yuv420p -c:v h264 -f rtsp -rtsp_transport tcp rtsp://127.0.0.1:8901/live1.mkv
使用 VLC 媒体播放器验证 RTSP 流输出：
1. 打开 VLC 媒体播放器。
2. 按 Ctrl+N。
3. 在输入栏中输入 URL rtsp://127.0.0.1:8901/live1.mkv。
4. 选择 Play。
