Konversi AVI ke MPG di Fedora 9

Konversi AVI ke MPG di Linux pada umumnya dan Fedora 9 pada khusunya dapat dilakukan manakala anda sudah memiliki paket yang bisa melakukan encoding dan decoding. Dalam kesempatan ini saya menggunakan MEncoder.

Untuk melakukan konversi, sebelumnya install dulu paket MEncoder. Karena saya menggunakan Fedora 9 atau IGOS Nusantara 3, saya bisa memanfaatkan fasilitas YUM. Untuk instalasi paket menggunakan YUM, anda harus menjadi super user.

Perintah baris:
# yum install mencoder

Code :
[root@lenovo ~]# yum install mencoder*

Selanjutnya anda tinggal melakukan konversi file AVI ke MPG. Misal, anda punya file input.avi dan mau dikonversi menjadi output.mpg. Maka perintah baris yang digunakan adalah sbb :

Perintah baris (buat dalam satu baris):
$ mencoder input.avi -of mpeg -mpegopts format=mpeg1:tsaf:muxrate=2000 -o output.mpg -oac lavc -ovc lavc -lavcopts acodec=mp2:abitrate=224:vcodec=mpeg1video:vbitrate=1152:keyint=15:mbd=2:aspect=4/3

Tulislah dalam satu baris.

Code :
[root@lenovo ~]# mencoder input.avi -of mpeg -mpegopts format=mpeg1:tsaf:muxrate=2000 -o output.mpg -oac lavc -ovc lavc -lavcopts acodec=mp2:abitrate=224:vcodec=mpeg1video:vbitrate=1152:keyint=15:mbd=2:aspect=4/3

Proses konversi seharusnya sudah berhasil. Sekarang anda tinggal memeriksa apakah file output.mpg sudah terbentuk.

Selamat mencoba.
