hey guys im trying to get stream from url then decode it and sent to my 
local rtmp:

https://www.twitch.tv/mystream`" -f alsa -f flv -ac 2 -ar 44100 -vcodec 
libx264 -g 60 -keyint_min 30 -b:v 3000k -minrate 3000k -maxrate 3000k

-threads 2 -strict -2 -bufsize 3000k rtmp://127.0.0.1/live3

errors like
