Subject: ffmpeg GPL violation

VoltaicHD 1.5 for Mac OS X

The program has a EULA that doesn't mention the GPL or ffmpeg. The program 
has a number of files buried in the Resources directory (choose "Show 
Contents"). One file is called Voltaic_c. This Voltaic_c *IS* ffmpeg. 
Voltaic_c converts files using a very familiar cli syntax:

$ prog=Voltaic_c; ps -axwwo command | grep -i "$prog" | grep -v grep
/Volumes/Voltaic-1.5.0/Voltaic.app/Contents/Resources/Voltaic_c -y -r 29.97 
-s 1440x1080 -i /tmp/ezlp2.yuv -i /tmp/ezlp2.ac3 -acodec pcm_s16le -ac 2 
-ab 192k -vcodec mpeg4 -sameq -b 24000k -f mov /tmp/ezlp2.vlt

$Voltaic_c -h

No indication AT ALL is given that ffmpeg is used, no GPL is provided. In 
fact, their EULA overrides the GPL:
YOU hereby undertake not to sell, rent, lease, translate, adapt, vary, 
modify, decompile, disassemble, reverse engineer, create derivative works 
of, modify, sub-licence, loan or distribute the SOFTWARE PRODUCT other than 
as expressly authorised by this EULA.

Please vilify & shame this program. Have a nice day.

form of tyranny and slavery out of the most extreme liberty. -- Plato
