Estou usando ffmpeg.exe para transcodificar uma fonte de vídeo, neste exemplo abaixo de um arquivo e deseja transmitir simultaneamente rmtp e salvar em arquivo. Eu não consigo descobrir o que estou fazendo de errado com o "tee pseudo-muxer". Aqui está o meu exemplo:
ffmpeg -re -i bbb1.mp4 -threads 2 -c:v libx264 -c:a aac -profile:v baseline -b:a 96k -strict:a -2 -b:v 200K -g 10 -s:v
320x280 -f tee -map 0:v -map 0:a "rtmp://127.0.0.1:1937/test_mid_002/t1.flv|output3.mp4"

Como a mensagem de erro diz, você pode usar mux apenas um fluxo de áudio em um FLV
