Tentando remover 1152 amostras, mas a fila está vazia

Question

Estou transmitindo arquivos mp3, usando este comando:

ffmpeg -re -i 'INPUT.mp3' -map_metadata -1 -map 0:0 URL

Eu crio um loop que flui arquivos, e não há problema em reviver o stream, apenas do servidor eu recebo esse erro

[libmp3lame @ 0x25088e0] Trying to remove 1152 samples, but the queue is empty

de outra resposta aqui eu adicionei a opção -write_xing 0, mas ainda assim recebi este erro alguma ideia de como resolver isso?

Aqui está um console de saída completo
