Estou tentando usar o ffmpeg para converter e normalizar o áudio em um arquivo wav em uma máquina com Windows 7. Parece que posso fazer isso sem nenhum problema, mas sempre que tento fazer ambos recebo esse erro do Windows Media Player tentando reproduzi-lo: "O Windows Media Player não pode reproduzir o arquivo. O Player pode não suportar o tipo de arquivo ou talvez não suporte o codec que foi usado para compactar o arquivo. "
Agora, isso é estranho para mim, porque se eu simplesmente converter o arquivo ou se apenas normalizá-lo, não há problema em reproduzi-lo. Além disso, não parece importar em qual ordem eu faço as operações ou se eu as testar em uma linha; o resultado é sempre o mesmo.
Para referência quando estou convertendo o arquivo, estou usando ffmpeg -i infile.wav -c:a aac -b:a 64k outfile.m4a e, quando estou normalizando, estou usando ffmpeg -i infile -af "loudnorm" outfile .
Alguém se deparou com isso ou tem alguma idéia para soluções?
Atualizar com o log:
Eu não tenho acesso aos arquivos em tamanho real que estou convertendo agora, mas abaixo está o log da chamada combinada em um arquivo de teste feito no mesmo equipamento.
