  i red this https://trac.ffmpeg.org/wiki/Creating%20multiple%20outputs

  


  I do this command

  


  /usr/bin/ffmpeg -re -i input.mp4 -deinterlace -c:v libx264 -pix_fmt yuv420p 
-preset veryfast -tune zerolatency -profile:v main -c:a aac -b:a 128k -ac 2 
-crf 19 -r 30 -g 60 -b:v 1369k -minrate 1369k -maxrate 1369k -bufsize 2738k 
-ar 44100 
-filter_complex "[0:v]split=2[s0]; [s0]scale=-2:1080[v0]" 
-map "[v0]" -map 0:a 
-f tee " [select='v:0,a':f=flv]rtmp://a.rtmp.youtube.com/live2/key | [select='v:0,a':f=flv]rtmps://va.pscp.tv:443/x/key "


  


  and I get in command line this

• Want to send a video from desktop to Wowza using ffmpeg

  3 mars 2018, par ST94

  I am trying to stream a local .mp4 video file from my laptop to Wowza Streaming Engine using ffmpeg. Both systems are able to ping each other. I give the following command on my laptop

  ffmpeg -re -i bunny_1080p_60fps_normal.mp4 -vcodec libx264 -acodec aac -ar 48000 -strict experimental -f flv "rtmp://192.168.1.22:1935/live/myStream"

  192.168.1.22 is the IP address of Wowza server residing on another system running Ubuntu 17.04.

  I see the following on the command prompt of my laptop when I give the above command,

  Can anyone please tell me what the exact procedure is to stream a video file to Wowza .

  How will I be able to view the stream at Wowza ?
