先说下环境，笔者处理器为Intel® Core™ i5-6300U CPU @2.40GHz。
srt推流，当推流端帧率过大，推流时，计算机性能跟不上，开始丢帧，就会出现这个错误，建立连接后，sls默认10s中没有接收到有效的数据信息，就认为这是个无效的连接会自动把它清除delete。
打开sls的配置文件srt-live-server/sls.conf，把其中的idle_streams_timeout由10s，改为30s，测试通过。
配置文件如下：
srt { #SRT worker_threads 1; worker_connections 300 ; log_file logs/error.log ; log_level info; #stat_post_url http://192.168.31.106:8001/sls/stat; #stat_post_interval 5;#s record_hls_path_prefix /tmp/mov/sls; #vod file name: /tmp/mov/sls/$listen/$domain_publisher/$app_publisher/$stream_name/vod.m3u8 server { listen 8080; latency 20; #ms domain_player live.sls.com live-1.sls.com; domain_publisher uplive.sls.com; backlog 100; #accept connections at the same time idle_streams_timeout 30;#s -1: unlimited #10s改为30秒 #on_event_url http://192.168.31.106:8000/sls/on_event; #?method=on_connect|on_close&role_name=&srt_url=%s app { app_player live ; app_publisher live ; record_hls off;#on, off record_hls_segment_duration 10; #unit s #relay { # type pull; # mode loop;#loop; hash; # reconnect_interval 10; # idle_streams_timeout -1;#s -1: unlimited # upstreams 127.0.0.1:9090?streamid=live.sls.com/live 192.168.1.100:8080/?streamid=live.test.com/live; #} #relay { # type push; # mode all; #all; hash # reconnect_interval 10; # idle_streams_timeout 30;#s -1: unlimited # upstreams 192.168.31.106:8080?streamid=uplive.sls.com/live ; #} } } }
