lspxsy commented 1 year ago

When you meet a bug, please open the issue including a title prefixed by '[bug]' and describe it as follows: (当你碰到一个 bug，请在提出问题时以 '[bug]' 为前缀写明标题，并且像下面的内容一样描述它):

Expected behavior (期望行为)

通过 ffmpeg -re -stream_loop -1 -i 01.mp4 -vcodec copy -f flv -y rtmp://127.0.0.1:1935/live/test 推流的时候会同时触发 exec_push 和 exec_pull

Actual behavior (实际行为)

OS and Nginx version (操作系统和 Nginx 版本号)

alpine nginx/1.23.3

Configuration file (配置文件)

# nginx.conf
rtmp {
  out_queue 4096;
  out_cork 8;
  max_streams 128;
  timeout 15s;
  drop_idle_publisher 15s;

  log_interval 5s;
  log_size 1m;
  server {
    listen 1935;
    chunk_size 4096;
    application live {
      live on;
      exec_options on;
      exec_push sh -c "/opt/media/test.sh PUSH $app $name>> /opt/media/log.log";
      exec_pull sh -c "/opt/media/test.sh PULL $app $name>> /opt/media/log.log";
    }
  }
}

# /opt/media/test.sh
array=$*
pre=[PID:$$]-[PPID:$PPID]-[UID:$UID]
suf="date +%Y%m%d%H%M%S"

COUNTER=0
while [ $COUNTER -lt 1 ]
do
    echo "$pre $array `$suf`"

    sleep 1
done

请保证推流的时候没有播放操作，另外，你的脚本是无限循环，只要有一个播放操作后脚本就不再退出。

是有开启flv_live:no的情况下推流的，上述的nginx配置忽略了http部分配置。是否是这个原因触发exec_pull？

上面给出的日志中，最后三个的 PULL myapp stream0 是 RTMP 播放，PULL myapp stream1 是 HTTP-FLV 播放，已就是开启了 flv_live on; 配置项，没有复现你说的问题。

感谢！怀疑是自己配置的问题，从新部署了一套，发现配置了
worker_processes auto;
的情况下，会出现上推流的时候，会触发exec_pull，而且$name是空。

另外，脚本无限循环，是为了测试停止推流或拉流的时候自动kill脚本。

不建议在多进程模式下使用 exec_pull，详情见：
