How to record logs of ffmpeg to a file?

fmpeg code outside the bash script works perfectly. For some reason when trying to write logs to a file using 2> - complains Unable to find a suitable output format for '2>'

I have the feeling that the system treats this as a command ffmpeg

cmd="ffmpeg -re -i "xx.m3u8" -c:v copy-c:a aac-b:a 128k -ac 2 -strict -2 -f flv rtmp://localhost:1935/hls/home5 2> /var/log/nginx/home5.log"
until $cmd ; do
 echo "restarting ffmpeg command..."
 sleep 2

You have there the same type of quotation marks in the first place. This is not good.
Second, you redirect the output do not there. Bad call syntax.
Declare the function, it do what you need with referral and call her.
Here about defining and calling functions:
function myfunc {
ffmpeg ... >> out.log
