合流需要打开配置文件的配置，主要是rtc的
vhost __defaultVhost__ { http_hooks { enabled on; on_publish http://host.docker.internal:8001/im-signaling-service/srs_callback/on_publish; on_unpublish http://host.docker.internal:8001/im-signaling-service/srs_callback/on_unPublish; on_play http://host.docker.internal:8001/im-signaling-service/srs_callback/on_play; on_stop http://host.docker.internal:8001/im-signaling-service/srs_callback/on_stop; on_dvr http://host.docker.internal:8001/im-signaling-service/srs_callback/on_dvr; on_hls http://host.docker.internal:8001/im-signaling-service/srs_callback/on_hls; on_hls_notify http://host.docker.internal:8001/im-signaling-service/srs_callback/on_notify/[server_id]/[app]/[stream]/[ts_url][param]; } rtc { enabled on; # @see https://ossrs.net/lts/zh-cn/docs/v4/doc/webrtc#rtmp-to-rtc rtmp_to_rtc on; # @see https://ossrs.net/lts/zh-cn/docs/v4/doc/webrtc#rtc-to-rtmp rtc_to_rtmp on; } http_remux { enabled on; mount [vhost]/[app]/[stream].flv; } }
我们这里是多人合流，于是使用ffmpeg，此处71a8de7是房间号，1～10是设备标识
ffmpeg \ -i rtmp://192.168.1.114/71a8de7/1 \ -i rtmp://192.168.1.114/71a8de7/2 \ -i rtmp://192.168.1.114/71a8de7/3 \ -i rtmp://192.168.1.114/71a8de7/4 \ -i rtmp://192.168.1.114/71a8de7/5 \ -i rtmp://192.168.1.114/71a8de7/6 \ -i rtmp://192.168.1.114/71a8de7/7 \ -i rtmp://192.168.1.114/71a8de7/8 \ -i rtmp://192.168.1.114/71a8de7/9 \ -i rtmp://192.168.1.114/71a8de7/10 \ -vf "scale=854:480" -r 24 \ -filter_complex " [0:v][1:v][2:v]hstack=inputs=3[Row1]; [3:v][4:v][5:v]hstack=inputs=3[Row2]; [6:v][7:v][8:v]hstack=inputs=3[Row3]; [9:v]scale=960:-1[Row4]; [Row1][Row2][Row3][Row4]vstack=inputs=4[Final]" \ -map "[Final]" \ -c:v h264_videotoolbox -profile:v high -b:v 1000k -q:v 23 \ -f flv rtmp://192.168.1.114/live/merge
然后播放
ffplay rtmp://192.168.1.114/live/merge
效果如下：
