PROTOCOL: HTTP-FLV performance issue, CPU Usage too high

[kioqq]

Hello @winlinvip . I have one more question :)

After i push stream(RTMP) from iOS and play .flv url in webplayer or VLC, srs usage 100% CPU why? o_o

VM: 4 core 8 gb mem 120gb ssd

My config:

listen              1935;
max_connections     1000;

http_server {
    enabled         on;
    listen          8080;
    dir             ./objs/nginx/html;
}

vhost __defaultVhost__ {

    transcode {

        enabled     on;
        ffmpeg      ./objs/ffmpeg/bin/ffmpeg;

        engine 720 {
            enabled         on;
            vfilter {
            }
            vcodec          libx264;

            vprofile        baseline;
            vpreset         veryfast;
            vparams {
                g           100;
            }
            acodec          libfdk_aac;
            abitrate        70;
            asample_rate    44100;
            achannels       2;
            aparams {
            }
            output          rtmp://127.0.0.1:[port]/[app]?vhost=[vhost]/[stream]_[engine];
        }

What's your SRS version? How many streams? How many players? How to replay this issue?

[kioqq]

@winlinvip Latest version from repo (git clone), 1 stream (RTMP), 1 player (HTTP-FLV). The load on the CPU begins at the moment when I open the HTTP-FLV link in player. If open RTMP link is ok.

[winlinvip]

Please use 2.0release branch. No time to fix bugs of develop branch, because I'm changing it huge day by day.

[kioqq]

@winlinvip 2.0release branch works great, thank you! 👍

[winlinvip]

Reopen for maybe bug for SRS3.

[kioqq]

@winlinvip please check this bug in dev branch, it's very important for me. I try fix it but can't find this bug now x_x if i understand this is a problem in the muxing rtmp -> http-flv. I also try to find the bug. -__- I'll tell you if I find :))

[kioqq]

hmm interesting, i can't reproduce this bug in dev branch if build srs on mac os Sierra o_0 but it's easy reproduced on CentOS 6/7 and Ubuntu12

[winlinvip]

Please DON'T use dev branch, it's not available.

[kioqq]

@winlinvip I use 2.0release it's ok, thank you 👍 But streams in 3.0 open faster it's important for me, but .flv streams broken 😩 . And i just try fix it 😃

[winlinvip]

You can file a issue to fix the 2.0 to fast startup.

Fixed in SRS3
