Mplayer

Introduction

Every Armadeus motherboard is capable of playing small MPEG videos with the help of the great Mplayer tool. It was successfully tested with 320x240 and 480x272 LCDs. Mplayer is using the Linux Framebuffer to display the videos.

Installation

[armadeus]$ make menuconfig

[armadeus]$ make

• then reflash your Rootfs

Usage

# mplayer -fs <-nosound> video.mpg

Troubleshots

• If you have a problem about a lib that can not be found during the link process, it's often an interaction between the host and the target. So you can disable the lib, with the buildroot/package/mplayer/mplayer.mk, editing the ./configure arguments
• disabling blinking cursor:

# echo 0 > /sys/class/graphics/fbcon/cursor_blink

or

# echo -e '\033[?17;0;0c' > /dev/tty0
