以下是我的配置文件
[global]
日志详细程度: 0=FATAL 1=ERROR 2=WARN 3=INFO 4=DEBUG
verbosity = 4
最大并发客户端数
maxclients = 20
UDPxy 兼容性
udpxy = yes
工作进程数（默认: 1）
workers = 1
检查 HTTP 请求的 Host 头 (默认：无)
#hostname = somehost.example.com
启用后，将使用 HTTP X-Forwarded-For 头作为客户端地址，用于显示在状态面板上 (默认：no)
并接受 X-Forwarded-Host / X-Forwarded-Proto 头作为 playlist.m3u 中的地址前缀
建议仅在使用反向代理时启用
xff = no
HTTP 请求认证令牌（可选，默认: 无）
设置后，所有 HTTP 请求必须携带 r2h-token 查询参数，且值与此配置匹配
例如:
http://server:5140/rtp/239.253.64.120:5140?fcc=10.255.14.152:15970&r2h-token=your-secret-token
http://server:5140/player?r2h-token=your-secret-token
#r2h-token = your-secret-token-here
状态页路径（默认: /status）
status-page-path = /status
播放器页路径（默认: /player）
player-page-path = /player
上游网络接口配置 (可选)
简单配置：只配置一个默认接口，所有流量类型都使用此接口
upstream-interface = enp2s0f0
高级配置：为不同流量类型配置专用接口
注意：专用接口配置优先级高于默认接口
#upstream-interface-multicast = enp2s0f0.43 # 组播流量 (RTP/UDP)
#upstream-interface-fcc = enp2s0f0 # FCC
#upstream-interface-rtsp = enp2s0f0 # RTSP
#upstream-interface-http = enp2s0f0 # HTTP 代理
混合配置示例：默认使用 eth0，但 FCC 使用更快的 eth1
upstream-interface = eth0
upstream-interface-fcc = eth1
优先级：upstream-interface-{multicast,fcc,rtsp,http} > upstream-interface > 系统路由表
外部 M3U 配置（支持 file://, http://, https://）
注意：HTTP/HTTPS 需要安装 curl 命令
#external-m3u = https://example.com/iptv.m3u
或使用本地文件
external-m3u = file:///root/rtp2httpd/playlist.m3u
外部 M3U 更新间隔（秒）
默认 7200（2 小时），设为 0 禁用自动更新
external-m3u-update-interval = 7200
组播周期性重新加入间隔（秒，默认: 0 禁用）
设置为正值（如 60）以周期性重新加入组播组
这是针对以下网络环境的兼容性解决方案：
- 启用 IGMP snooping 的交换机在没有路由器 IGMP Query 时超时
- 配置不当的网络设备会丢弃组播成员关系
推荐值: 30-120 秒（小于典型交换机超时 260 秒）
注意：默认禁用（0），仅在遇到组播流中断时才需要启用
mcast-rejoin-interval = 0
~:workers
FCC 监听媒体流端口范围（可选，格式: 起始-结束，默认随机端口）
fcc-listen-port-range = 40000-40100
缓冲池最大缓冲区数量（默认: 16384）
每个缓冲区 1536 字节，16384 个约占用 24MB 内存
增大此值以提高多客户端并发时的吞吐量，例如设置为 32768 或更高
buffer-pool-max-size = 16384
UDP socket 接收缓冲区大小（默认: 524288 = 512KB）
作用于组播、FCC、RTSP RTP/RTCP 所有 UDP socket
对于 30 Mbps 的 4K IPTV 流，512KB 可提供约 140ms 的缓冲
增大此值以减少高带宽流的丢包
实际缓冲区大小可能受内核参数 net.core.rmem_max 限制
udp-rcvbuf-size = 524288
启用零拷贝发送以提升性能（默认: no）
设为 yes/true/on/1 以启用零拷贝
需要内核支持 MSG_ZEROCOPY (Linux 4.14+)
在支持的设备上可提升吞吐量并降低 CPU 占用，特别是在高并发负载下
如果你的 rtp2httpd 位于反向代理之后 (nginx/caddy/lucky 等)，不建议开启这个选项
zerocopy-on-send = yes
STUN 服务器用于 RTSP NAT 穿透（默认: 禁用）
当 RTSP 服务器仅支持 UDP 传输且客户端位于 NAT 后时，可尝试使用 STUN 进行 NAT 穿透（不保证成功）
格式: host:port 或 host（默认端口 3478）
#rtsp-stun-server = stun.miwifi.com
启用视频快照功能（默认: no）
启用后可通过 snapshot=1 查询参数获取视频流的实时快照
video-snapshot = no
FFmpeg 可执行文件路径（默认: ffmpeg，使用系统 PATH）
如果 ffmpeg 不在 PATH 中或想使用特定版本，请指定完整路径
ffmpeg-path = /usr/bin/ffmpeg
FFmpeg 额外参数（默认: -hwaccel none）
这些参数在生成快照时传递给 ffmpeg
常用选项: -hwaccel none, -hwaccel auto, -hwaccel vaapi, -hwaccel qsv
ffmpeg-args = -hwaccel vaapi
[bind]
监听所有地址的 5140 端口
- 5140
监听特定 IP 的 8081 端口
支持多个监听地址
[services] 内可以直接编写以 #EXTM3U 开头的 m3u 节目清单
和 external-m3u 功能类似，只是直接把 m3u 写在了配置文件内
