The 5th day working at Happy Island.
Development environment:
- VIA Nano X2 (w/ dual-core X86) processor and VX900 media processor
- Ubuntu Linux 10.04.04 (Lucid) -- upgrade to Ubuntu 11.04 later on.
Today's Highlights:
- being able to play DVB-T with mplayer on the VIA eval. board;
(Have to connect a "good" antenna to the main (master) connector on the DiBcom USB module, though.)
However, in Taipei the settings in /usr/share/dvb/dvb-t/tw-Taipei initial scan file must be modified before using 'scan' to generate channels.conf. The modified tw-Taipei initial scan file is as shown below.

TBD:
For mplayer:
- To find out why screen black-out occurs from time to time; (Solved -- this problem only occurs in the Ubuntu 10.04.04 environment)
- To re-build mplayer with a GUI skin. (Done)
To be explored:
- How to make a bootable USB pen drive (can it have a boot image like a CD-ROM?)
