Stream video to a least 50 smarthphones (100% CPU problem)

[TMC 2]

Hi, we are developing a infotaiment project to our college, what we want to use is emby as a video server, our goal is connect at least 50 smartphones to MB, but right now we have a big issue because when the phone number 10 is connected to the server the CPU usage is 100% and the video delay.

 

We want to now if MB could be the solution to this project?

what is the format of the video?

We are trying with the Big Bunny movie: https://peach.blender.org/download/ And also we are running MB on a virtual machine on Parallels:

is the video transcoding or direct streaming?

[TMC 2]

Direct streaming, but we can control the videos, wich recommend you?

[Luke 39648]

can you post the server log from when you tried 10 phones? thanks.

Server log (with 1 to 20 phones)

Transcode logs

 

And a picture (here we are trying with SINTEL)

Ok, so they are transcoding. That is the reason. You want to use mp4 with h264/aac, and check the bitrate setting in the web client. If you do that and you can get them to direct stream, there will be no transcoding logs produced and it should handle 50 no problem.

We will try tonight and tell you the advance.

You want to use mp4 with h264/aac, 

I hate to ask, but .... could you provide more details than that?

Or an example ffmpeg command line to convert the file to an ideal codec?

This would be GREATLY appreciated!!

just research what the browsers can play with html5 video. or use the folder sync feature and let it handle it for you

Something else comes to mind....  I assume all of these devices (for testing) are on wifi?  the same wifi AP?

Yes they are on the same AP, but all of theam use ffmpeg to transcode de video and that make a 100% CPU usage
