Saya tidak dapat menggunakan aviread di GNU Octave pada Windows 10. Banyak situs meminta saya untuk menginstal paket video, tetapi saya mendapatkan kesalahan ini saat instalasi.

Bolehkah saya tahu cara menginstal paket ini. Sebagian besar situs mengatakan itu sudah usang tetapi tidak satupun dari mereka memberikan solusi untuk masalah saya. Jika tidak, apakah ada cara lain untuk membaca file AVI (selain mengonversi file itu sendiri)?
