Arquivos .dav vazios ao fazer download de vídeos

[brunoaduarte]

Olá @wiltonsr

Após executar o comando para listar os arquivos todos são baixados pelo script mas ficam vazios.
Será que eles mudaram a API nas últimas versões?

Olá, @brunoaduarte

Houve esse mesmo problema há pouco tempo #3
O fato de nem via navegador funcionar o download demonstra que o problema é de fato com a API e não com a lib.

Infelizmente não tenho um equipamento mais novo para realizar um investigação mais detalhada.
