FFplay Movie Evolution Files

FFplay Movie Evolution
Evolving playing movies.

Prerequisites:
xdotool
ffmpeg
and optionally xterm
Written under running X server @ CentOS 7 with qt4 libraries.

ffmpeg installed in Centos 7 from 
https://copr.fedorainfracloud.org/coprs/scx/ffmpeg-free/

Select input source (like file, cam as dev/video0, ...), set launching 
options and filters, play, and control graphic unit relative tasks.

Using combo boxes will be more easy unchecking 'R' (autorise)
button or, pressing keyboard button and selecting, using keyboard keys
or mouse wheel. All context unmanaged menu may close if main graphic
unit component rise over all automatically with dedicated timer.

Centos 7 qt4 quick install
yum install qt-config qt-creator qt-devel
----
X server generic quickstart:
In run level 4, after operating system initialization reached multi user target,
start X server from root e.g. so:
# X :0
Then, login as user and type, e.g. xterm or qtcreator or your program
$ DISPLAY=:0 xterm &
----
Quick start for this program (# as root, $ as user):
From a terminal (having reached run level 4)
# X :0
From another terminal
$ DISPLAY=:0 xterm -e '/yourpath/centos-ffplaymovievol-Desktop-Release/ffplaymovievol' &
or
$ DISPLAY=:0 xterm &
$ chvt 2 //2 or where X server is running
$ /yourpath/centos-ffplaymovievol-Desktop-Release/ffplaymovievol //inside xterm
----

This program run in Linux Operating System initialized reaching run level 4.
This run fine if isn't nested to any user operating method layer pack of software.
This program isn't tested over X server main bitmap running as window of host
operating system [like host - window (as graphic "hole" of host O.S.) - 
virtual machine or other sometimes named "sub-system"].
With asterisk and your pointer device, in standard output over X server bitmap, you can
move visual graphic unit standard input interface.
