Sungha Jung dan script youtube-dl di Ubuntu Lucid

Philip — Sun, 14 Nov 2010 06:48:50 +0000

Gara-gara Iful Spock, aku jadi kecanduan dengerin Sungha Jung, bocah 14 tahun dari Korea Selatan yang permainan gitarnya sudah kelas maestro.
Cek di channelnya Sungha Jung di Youtube, ternyata dia sudah posting lebih dari 200 video musiknya. Wah, dengerin yang mana duluan nih? Setelah dipilih-pilih, ada sekitar 30 video yang ingin aku lihat.
Masalahnya, kalau distreaming satu-satu, bisa 2 hari dengan koneksi di rumah. Tanya ama mbah google, ternyata ada script youtube-dl.
Pertama kucoba yang di repo Ubuntu:
sudo apt-get install youtube-dl
Sesudah terinstall, kucoba dengan salah satu video tadi. Eh ternyata yang ada di repo Ubuntu versi yang sudah agak lama (April 2010), dan Youtube sudah merubah banyak hal sejak April, jadi downloadnya gagal.

Ya sudah, kuhapus yang dari repo tadi, dan kuinstall langsung dari github.
sudo apt-get remove youtube-dl --purge wget -c https://github.com/rg3/youtube-dl/raw/2010.10.24/youtube-dl --no-check-certificate chmod +x youtube-dl sudo cp youtube-dl /usr/bin
OK, script youtube-dl udah siap, sekarang siapkan satu folder khusus untuk download ini.
mkdir 'Videos/music/Sungha-Jung' cd 'Videos/music/Sungha-Jung'
Trus siapkan daftar link Youtube yang sudah dipilih tadi, masukkan dalam satu file, disini aku pake nama “todl.txt”
gedit todl.txt
Sekarang mulai mendownload. Berhubung fakir spes dan benwit, maka aku pilih videonya yang tipe 18 (MP4, AAC, 480×360) sesuai dengan daftar format Youtube
Perintahnya seperti ini:
youtube-dl -f 18 -o '%(stitle)s.%(ext)s' -a todl.txt -c
Yes!
Ditinggal tidur, dan paginya playlist Sungha Jung sudah siap!

Penipuan episode 2

Philip — Wed, 29 Sep 2010 12:44:49 +0000

Baru kemarin kuposting email aslinya, eh si penipu yang berkedok sebagai “John Raymond” mengirim lagi email yang sama persis padaku.
Bedanya, dia mengirim menggunakan SMTP server yang berbeda, dan kali ini “To:” nya langsung ditujukan padaku.

Ancene jaman edan!

Penipuan (lagi-lagi)

Philip — Mon, 27 Sep 2010 06:37:53 +0000

Makin banyak media komunikasi, makin banyak aja cara orang untuk menipu.
Baru seminggu lalu ibuku menerima sms yang bunyinya,

Ini nomer baru mama. Tolong isikan pulsa. Cepat yah. Urusan penting nih!

Jelas ibuku cuman senyum aja, soalnya kayaknya pulsa surga – dunia agak berbeda

Kalau yang contoh di bawah ini via email, pura-puranya jadi orang UN :

VirtualBox : No networking on copied/imported guests

Philip — Mon, 29 Mar 2010 08:05:13 +0000

Beberapa minggu ini lagi sibuk ngoprek website dengan MovableType yang jalan di Apache di salah satu virtual machine di VirtualBox.

Kesulitan timbul ketika aku menyalin virtual machine ke VirtualBox milik klien.
Ini langkah yang kulakukan:
1. copy file *.vdi dari /home/user/.VirtualBox/HardDisks ke laptop klien, di folder yang sama
2. Buat virtual machine baru di klien, arahkan harddisknya ke file *.vdi yang disalin tadi
3. Pastikan setting virtual machine yang baru sama dengan yang lama
4. Boot virtual machine

Setelah virtual machine di laptop klien ku boot ternyata tidak ada network interface yang terdeteksi.
Hasil ifconfig menunjukkan hanya lo saja yang up
Perintah :
sudo ifconfig eth0 up
malah menghasilkan error yang menyatakan interface tidak ditemukan

Googling dikit, ternyata ketemu ini: No networking on copied/imported guests

Ternyata, virtual machine yang jalan di bawah VirtualBox (aku pakai Ubuntu Hardy 8.04.3 JEOS) dikunci network interfacesnya ke MAC Address tertentu saja di /etc/udev/rules.d/70-persistent-net.rules . Gejalanya, kalau dijalankan :
dmesg | grep udev
pasti ada baris macam ini:
udevd: renamed network interface eth0 to eth1

Jadi tinggal disamakan saja MAC Address yang dipakai di virtual machine di laptopku dengan yang di laptop klien, dan apache pun jalan lagi dengan lancar

Ngoprek MovableType: ImageDriver

Philip — Wed, 16 Sep 2009 05:13:12 +0000

Akhirnya berhasil juga mengonlinekan websitenya Rotary Ubud Sunset. Waktu coba login ke enginenya (pake MovableType Open Source) , eh mendadak muncul warning :

Image::Magick is either not present on your server or incorrectly configured. Due to that, you will not be able to use Movable Type’s userpics feature. If you wish to use that feature, please install Image::Magick or use an alternative image driver.

Cek kiri-kanan ternyata hosting yang kupakai memang ndak memasang Image::Magick , dan berhubung males berdebat dengan adminnya, maka aku ganti saja image drivernya. Caranya mudah kok, tinggal tambahkan 1 baris ini :

ImageDriver GD

atau

ImageDriver NetPBM

di dalam mt-config.cgi .

Beres dah!

A thousand more bugs to squash! Fiuh!

Convert Video di Ubuntu

Philip — Thu, 22 Jan 2009 09:24:16 +0000

Skenarionya begini:

Kolegamu memberikan sebuah file video (katakanlah blabla.avi), codecnya masih uncompressed AVI dengan audio PCM, hasil keluaran Adobe Premiere, besarnya 1,8 GB, lengkapÂ dengan pesan, “Mas tolong uploadin ke Youtube yah, buat promosi kita.”

Koneksi kantor pake Speedy Unlimited Office, yg berarti bandwith tidak terlalu lebar, kalau dipaksakan 1,8 GB diupload bisa mampus berhari-hari koneksinya. Plus, Youtube membatasi besar file hanya maksimal 1 GB. Berarti file video ini harus dikompresi habis-habisan, dan codecnya harus disesuaikan dengan ketentuan Youtube (H264/AAC)

Bagaimana caranya?

Asumsi : OS yang kau gunakan adalah Ubuntu Intrepid

Langkah yg perlu dilakukan (dimodifikasi dari sini:

Pastikan paket yang diperlukan sudah terpasang

sudo apt-get install mencoder mplayer faac gpac mpeg4ip-server x264 libdvdread libdvdcss

Pisahkan aliran suara dari berkas aslinya, dan ubah ke format AAC. Perhatikan parameter -C 2 , ini untuk aliran suara 2 kanal (stereo), sesuaikan dengan jumlah kanal pada berkas asli

mplayer -vc null -vo null -ao pcm -benchmark blabla.avi

faac --mpeg-vers 4 -q 100 -P -R 48000 -C 2 -I 5,6 -X audiodump.wav -o audio.aac

Apabila videonya perlu dicropping, maka cari batas-batas peng-cropping-annya dengan perintah berikut:

mplayer -vo null -vf cropdetect blabla.avi

Hasil dari perintah di atas adalah ukuran pemotongan video yang terdeteksi. Hati-hati, nilai terdeteksi bisa bervariasi karena fluktuasi ukuran video. Ambillah nilai terbesar (pemotongan paling sedikit) agar tidak ada bagian video yang terbabat secara tidak sengaja. Nilai terdeteksi tersebut dimasukkan ke -vf crop=xxx:xxx:xx:xx dalam perintah di bawah. Apabila tidak diperlukan pemotongan, hapus paramater -vf crop=xxx:xxx:xx:xx .

Berikutnya, pisahkan aliran gambar (video stream) dalam 2 pass, convert ke H264

mencoder -nosound -of rawvideo -ovc x264 -vf crop=xxx:xxx:xx:xx,scale,harddup -x264encopts bitrate=1000:frameref=6:analyse=all:me=umh:subme=7:trellis=2:bframes=1:subq=7:brdo:mixed_refs:weight_b:bime:no_fast_pskip:direct_pred=auto:mixed_refs:nr=200:threads=auto:turbo=2:pass=1 -noskip blabla.avi -o /dev/null

mencoder -nosound -of rawvideo -ovc x264 -vf crop=xxx:xxx:xx:xx,scale,harddup -x264encopts bitrate=1000:frameref=6:analyse=all:me=umh:subme=7:trellis=2:bframes=1:subq=7:brdo:mixed_refs:weight_b:bime:no_fast_pskip:direct_pred=auto:mixed_refs:nr=200:threads=auto:pass=2 -noskip blabla.avi -o movie.264

Lalu convert videonya ke container mp4. Perhatikan parameter -rate 25 , ubahlah menyesuaikan dengan parameter video aslinya (kebanyakan video PAL menggunakan frame rate 25)

mp4creator -rate 25 -a movie.264 movie.mp4

Sekarang satukan aliran suara dan gambarnya

MP4Box -add audio.aac movie.mp4

Selesai!
Tinggal mengupload movie.mp4 ke Youtube!

Fiuh!

Kesandung Lontara

Philip — Wed, 28 May 2008 08:53:48 +0000

Setelah beberapa kali crash Windows XP di komputer kantor, akhirnya nggak tahan juga untuk menginstall Linux. Gara-gara disekem Farhan, akhirnya aku coba Blankon Lontara.

Coba LiveCD…. ok

Coba install….. anjrit! gak ada gparted nya! Jadi gak bisa partisi manual!

OK, ambil MiniPE, bikin 3 partisi: swap , / , dan /home

Masukkan Live CD lagi, install……….ok lancar,Blankon terinstall dan running

Sekarang coba mainkan beberapa file anime, karena sekem Farhan menyatakan Blankon sudah terinstall codec yang dibutuhkan untuk memainkan anime. Testing………. anjrit! gstreamer0.10-ffmpeg nggak ada, minta diinstall dulu.
Ok, sekarang coba install gstreamer0.10-ffmpeg ……….. anjrit! synaptic memuntahkan error!
Cek milis Blankon…….. ketemu tret ini. Ooo ternyata memang ada masalah di sources.list yang dihasilkan waktu install.
Ok, oprek time!

sudo gedit /etc/apt/sources

Trus copas ini:

Sekarang dites…… Ok! Paket terpasang!

Fiuh!

Kesimpulan sementara tentang Lontara:

Pemasangan cukup sederhana hanya bila dipasang pada komputer yang masih kosong. Pada kasusku jadi sulit karena sudah terinstall Windows, dan pada installer tidak disediakan tool partisi yang cukup baik dan mampu menangani NTFS.
Kalau memungkinkan, segera dirilis versi 3.0.1 yang memuat perbaikan sources.list dan menambahkan paket codec (supaya sesuai sekemnya Farhan). Ini terutama untuk mengantisipasi timbulnya kesulitan diatas pada peserta roadshow Linux (yang kemungkinan besar adalah newbie)

Gimana?

Uninstall Internet Explorer dari Windows XP

Philip — Wed, 07 Jul 2004 02:03:43 +0000

Ternyata aku bukan satu-satunya orang yang sebal dengan Internet Explorer, Outlook Express dan Windows. Dari sekian banyak keluhan soal komputer di tempat kerjaku 95% terkait dengan virus, trojan, dan worm yang menjebol retakan keamanan di seluruh produk Microsoft. Saat ini, aku sudah berhasil memaksa hampir semua staff untuk tidak mengunakan Outlook Express dan menggantinya dengan The Bat. Internet Explorer sudah mulai tergantikan dengan Firefox, walaupun proses pergantiannya agak susah karena IE terintegrasi dengan keseluruhan Windows. Akhirnya dengan bantuan nLite IE berhasil dikudeta sepenuhnya. Berikutnya menggantikan MS Office dengan Open Office, lalu menggantikan Windows dengan Xandros Linux. Untuk dua yang terakhir kurasa masih butuh waktu panjang untuk membiasakan para user……
