'How to change bitrate on ffmpeg stream?
After i saw a tutorial on youtube i tried to stream a radio 24/7 on youtube with a looping mp4 and azuracast. So far so good, but with a problem. I rend a VPS from vultr with ubuntu 18.4 , 1cpu 2gb ram, everything works smoothly but even if the down/up speeds of vps are more than 300mbps, i cant get my bitrate to run more than 2200kbps on streams, and end up with buffering if i try to raise that or no stream at all. I run the exact code written on tutorial. Is there anything i can do about it? (2 days since i started the stream, 2 times a pipe error and something with header ended the stream after 18 continuous hours of play). Im a newbie on ffmpeg and linux but im learning fast! Since i connect remotely i noticed that if i copy paste all the code together it doesnt recognise the ffmpeg / command so i had to copy paste half and each line after the ffmpeg command to work to check the error, because i cant find a way to write a log of it… Thanks in advance!
