Cara konversi movie untuk PSP

Sebelum bisa jalanin movie di PSP.. harus dikonversi dulu. Ini batasannya:

• Video Codec: xvid, divx, H.264
• Audio codec: FAAC
• File Format: mp4
• Bit rate harus <= 768 kbps
• Resolution: 320x240, 640x480

Cara konversinya bisa menggunakan tool ffmpeg. Kalau mau hasilnya bagus.. command line-nya panjang banget. Biar gampang pake script ini aja:

################################# script start: konvertpsp
INPUT="$*"

# harus .mp4
OUTPUT="out.mp4"

# 2-31
QUALITY=21
#################################

if [ "$INPUT" = "" ]; then
echo "Please specify input file"
exit
fi

opt1=" -vcodec libx264 -coder 1 -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -me_method hex -subq 6 -me_range 16 -g 250 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -b_strategy 1 -level 21 -refs 2"

opt2="-cqp $QUALITY"

opt3="-ab 64k"

opt4="-s qvga"

echo -- -- ffmpeg -i "$INPUT" $opt1 $opt2 $opt3 $opt4 -threads 3 $OUTPUT
ffmpeg -i "$INPUT" $opt1 $opt2 $opt3 $opt4 -threads 3 $OUTPUT

########### script end

Cara jalanin:
./konvertpsp namafile.avi

Outputnya: out.mp4

Chatting lokal (LAN)

Ok..... gimana caranya chatting lokal antara teman sekantor? tapi bukan menggunakan Yahoo messenger, Jabber, MSN, dll... chatting tanpa menggunakan Server?

Dengan menggunakan pidgin kita bisa chatting di LAN tanpa menggunakan server. Protokol yang digunakan adalah Bonjour. Tambahkan account di masing-masing komputer:

Ubah First Name dan Last Name:

Setelah itu login dan semua user di LAN otomatis akan muncul di Buddy List:


- Bonjour menggunakan backend Avahi (zeroconf) ... kompatibel di Windows, OSX, Linux.. ini yang bikin keren ^^
