When looking for help, you should try to trim your command-ling of all
things that do not matter for your issue (codecs parameters, etc.), that
will help people to spot the issue.

If you did that, you would probably have noticed that you have two
conflicting -f options, although this is not the cause of the issue.

tee can not guess what format you want for the RTMP output. This is probably
what the original "-f flv" was for. Use "[f=flv]", that should be enough.
