/*
AiO stb screengrabber

Based on the work of Seddi
Contact: seddi@ihad.tv / http://www.ihad.tv

This standalone binary will grab the video-picture convert it from
yuv to rgb and resize it, if neccesary, to the same size as the framebuffer or
vice versa. For the DM7025 (Xilleon) and DM800/DM8000/DM500HD (Broadcom) the video will be
grabbed directly from the decoder memory.
It also grabs the framebuffer picture in 32Bit, 16Bit or in 8Bit mode with the
correct colortable in 8Bit mode from the main graphics memory, because the
FBIOGETCMAP is buggy on Vulcan/Pallas boxes and didnt give you the correct color
map.
Finally it will combine the pixmaps to one final picture by using the framebuffer
alphamap and save it as bmp, jpeg or png file. So you will get the same picture
as you can see on your TV Screen.

There are a few command line switches, use "grab -h" to get them listed.

A special Thanx to tmbinc and ghost for the needed decoder memory information and
the great support.

Feel free to use the code for your own projects. See LICENSE file for details.
