MySQL Encoding

You need to change params for the server and the client.

# Change MySQL server encode
# By calling the following SQL you can see the current encoding.
# show create table xxx;
# show variables like 'char%';

mysql$ alter table xxx character set utf8;
mysql$ alter table xxx change sub1 sub1 varchar(256) character set utf8;
mysql$ set names utf8;
mysql$ set character_set_database=utf8
mysql$ set character_set_server=utf8

#On the client to connet to DB set the following param in URL
jdbc:mysql://localhost/blojsom?autoReconnect=true&useUnicode=true&characterEncoding=utf-8

Encoding to 3gp file for mobile phones

If h/s support AAC.

#ffmpeg -i infile.mpeg -vcodec mpeg4 -r 15 -b 128k -s qcif -acodec aac -ar 8000
-ac 1 -ab 13 -f 3gp -y output.3gp

If not

ffmpeg -i infile.mpeg -vcodec mpeg4 -r 15 -b 128k -s qcif -acodec amr_nb -ar 8000
-ac 1 -ab 13 -f 3gp -y output.3gp

For video editing on Linux, LiVES would be very nice.
