essa é uma das saidas de
ffprobe -loglevel 0 -print_format json -show_streams C:\Users\xiyun\Downloads\Parasite.2019.MULTi.COMPLETE.UHD.BLURAY-MMCLX\BDMV\STREAM\00000.m2ts
mas não está vindo o idioma do áudio, mas no MPC-HC ele está aparecendo, como obter mais metadados para conseguir saber o idioma?
segue a saída completa:
