maybe srt version is not right?

[Edward-Wu]

hi, chenwdong, please paste your command, or maybe you can add 'sudo' before your command.

[chenwdong]

./sls -c ../sls.conf

[chenwdong]

srt {
worker_threads 2;
log_file logs/error.log ;
log_level info;
worker_connections 300 ;
server {

hi,what is your os, and version?

[chenwdong]

CentOS Linux release 7.2.1511 (Core)

[chenwdong]

Are you compiling with the latest version, is the result different?

[chenwdong]

[chenwdong]

Is it where I am doing wrong?

[chenwdong]

I really want to try the latency, but I haven’t run it all the time.

[Edward-Wu]

today i will use the lastest version of srt to test. please wait a minute.

[Edward-Wu]

hi, please use the srt 1.3 temporary, i will spent time to resolve this issue on v1.4.
thank you.

[chenwdong]

thank you !

[Edward-Wu]

hi, chenwdong
can you paste your cmd about flow stopped for a short while?

btw, i test the libsrt v1.4.0 for this issue, the reason is that srt update the result of srt_epoll_wait function , i have consulted with srt-team but no feedback.

if you want use the libsrt v1.4.0, you can change the function CSLSGroup::handler() in SLSGroup.cpp file(Line:110):

change from:
if (ret == SRT_ETIMEOUT)//6003
ret = SLSERROR(EAGAIN);
else
ret = CSLSSrt::libsrt_neterrno();
to
if (ret == SRT_ETIMEOUT)//6003
ret = SLSERROR(EAGAIN);
else{
//ret = CSLSSrt::libsrt_neterrno();
}

i will wait for srt-team about the reason.

[chenwdong]

Stopped for a short while This problem is my operation error, srt1.3 is OK

[chenwdong]

Hi, Wu I have an idea to develop srt-live-server into a nginx plugin, similar to nginx-rtmp-module, so that the uplink uses srt push stream, the downlink can be converted to rtmp, hls, http-flv, srt for streaming, This live broadcast will have udp mode and is compatible with rtmp，what do you think?

hi, chenwdong.
it's very good idea to add srt to nginx. i know nginx event based on epoll also.but srt encapsulates epoll within its api, mybe you need to think them clearly.

[chenwdong]

I know that epoll is just an engine of nginx. It is completely possible to replace epoll of nginx with epoll of srt.

[chenwdong]

i will try

[Edward-Wu]

hi, chenwdong
i has resolved this issue according to the srt team's suggestions and updated sls source code. If you want to know the detail about please see Haivision/srt#918

hope your great work about sls with nginx.

thank you.

[chenwdong]

thank you!

[chenwdong]

good
