cpu usage

[tobisaki]

thank you for your help.

When i tried my application, that customized /usr/local/FlashphonerWebCallServer-5.0.2267/client2/examples/demo/streaming/player/player.html
cpu usage max.
and many messages written to gc-core.log
whats wrong?

Please attach:

• Your customized player.js file (zipped)
• cat /proc/cpuinfo
• WCS_HOME/conf/flashphoner.properties

We will check.

You see Allocation Failure logs because you have to add heap memory in WCS_HOME/conf/wcs-core.properties
Replace

-Xmx1024M

with

-Xms2048M -Xmx4096

Then do WCS restart

service webcallserver restart

Max san, anytime thank you for your help!
i planed about 50 ip-cam and each cam have many viewer.
testing h/w have 16gb memory.
application is made node.js, it does not require much memory.
What is the correct wcs-core.properties memory setting?

According our tests, one IP camera H.264+AAC utilizes about 30% of 1 core CPU.
This load is caused by audio transcoding from AAC to Opus (WebRTC).

If we test video only, without audio playback, it utilizes 3% of 1 core CPU.

 var options = {
        name: streamName,
        display: remoteVideo,
        flashShowFullScreenButton: true,
        constraints: {audio:false,video:true}
    };
...
stream = session.createStream(options).on(STREAM_STATUS.PLAYING, function(stream){
...
}

So, for 50 cams, you need 1 core CPU per 3 cams with AAC audio.
Or 1 core CPU per 30 cams without AAC audio.

If you cam supports G.711 audio codec, you can optimize CPU load using H.264+G.711 encoding on IP camera end.

Max san, thank you for detail infomation.
so i could understand, and I felt more study is necessary, thank you so much.
i have never heard of g.711
