Kadang kesel juga biarpun internet dah kenceng, tp streaming berasa lambat …
Apalagi kl kita sering akses video itu, atau temen2 sekantor pada akses video yang sama …
Kebayang brp gede benwit yg abis utk akses video tsb, kl tiap orang streaming lsg

Setelah googling2 … akhir nya nemu solusi nya … yaitu videocache, sebuah url rewriter utk squid.
Cara install nya gak ribet, krn dia cmn sekedar python script.

Script ini berlaku utk situs2 seperti:
Youtube, Vimeo, Dailymotion, Metacafe, Google Video, dan beberapa situs video streaming porno

Persiapan:
1. http://pypi.python.org/packages/source/u/urlgrabber/urlgrabber-3.1.0.tar.gz
2. http://iniparse.googlecode.com/files/iniparse-0.3.1.tar.gz
3. ftp://ftp.estpak.ee/pub/FreeBSD/ports/distfiles/videocache-1.9.2.tar.gz

Download dan extract ketiga file di atas. Lalu install masing2 dengan cara:
* python setup.py install

Nah … berikutnya edit file /etc/videocache.conf
Edit bagian ini, sesuaikan dengan setting squid Anda …
proxy = http://127.0.0.1:3128/

Lalu edit file squid.conf Anda, dan tambahkan baris berikut:
url_rewrite_program /usr/share/videocache/videocache.py
url_rewrite_children 20

Tidak ada yg perlu dimodif utk bagian ini … biarkan saja apa ada nya …
Lalu tinggal direstart aja squid nya …

Nah kalo misalkan gak jalan … coba cek ownership:
- /var/log/videocache/videocache.log
- /var/spool/videocache
Pastikan ownership nya sama dengan uid yg menjalankan squid …

Apabila video baru pertama kali diakses, biasanya loading pertama agak lama … tp begitu udah play, hampir nyaris terputus … tergantung koneksi internet juga ya. Tp setidaknya jauh lebih mendingan drpd tanpa videocache ini.
En kl diakses lagi, gak bakal loading dari nol lagi

Semoga bermanfaat …

* Config ini udah saya pasang di Linux en di MacOS X
