python+ffmpeg视频并发直播压力测试
作者:LZT-LHZ
这篇文章主要为大家详细介绍了python+ffmpeg视频并发直播压力测试,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
通过python与ffmpeg结合使用,可生成进行视频点播、直播的压力测试脚本。可支持不同类型的视频流,比如rtmp或者hls形式。
通过如下方式执行脚本:python multiRealPlay.py [rtmp|http] [thread counts] [interval Time]
[rtmp | http]:视频播放的不同形式
[thread counts]:并发线程数
[interval Time]:启动每个线程的间隔时间
