在nginx-rtmp上的实时流之后未调用exec_record_done

编程问答 2022-06-04

问题描述

我不知道为什么这里没有叫exec_record_done。 on_record_done被调用，但exec_没有被调用。我已经检查了脚本文件，并且烫发一切正常。 Nginx日志中没有关于exec_record_done的任何内容...有任何进一步调试的想法或建议吗？

application live {
        live on; # Allows live input

        # for each received stream,transcode for adaptive streaming
        # This single ffmpeg command takes the input and transforms
        # the source into 4 different streams with different bitrates
        # and qualities. # these settings respect the aspect ratio.
