Siguiendo de esta pregunta (donde estoy convirtiendo las grabaciones de televisión WTV y DVR-MS en H.264 / MPEG-4 AVC para reducir el espacio), dada la salida de ffmpeg -i <filename>
, ¿cómo puedo averiguar si debo desentrelazar o no el archivo convertido?
La salida de uno de estos archivos se muestra a continuación:

así que supongo que debería desentrelazar esto.
