¿Alguien reconoce este error y qué se puede hacer al respecto?

Respuesta1

Error -2

2 ENOENT No such file or directory. 
A component of a specified pathname did not exist, or the pathname was an empty string.

En este caso significó:

  • No escribió el nombre de archivo o la ruta de archivo correctos, o
  • no tienes permiso para leerdesde el archivo/ruta que escribió.

Respuesta2

¡Terminó siendo un problema de permisos! Resultó que no era el propietario de la carpeta a la que estaba enviando. La solución fue algo así como

chown $USER folder

Respuesta3

Tuve el mismo problema y pude superar el bloqueo usando "configuraciones avanzadas" para intentar ralentizar las cosas.

Parece estar funcionando

No estoy seguro de si lo que he cambiado puede afectar negativamente la calidad del vídeo/audio (muy novato ;-)
