I think it boils down to if they are following the
License Compliance Checklist or not.
I'm not going to investigate it but skimming through the FAQ I kind of doubt that *SPAM URL* is 100% compliant.
Furthermore *SPAM URL* offers paid software yet the website had no direct contact information (phone number, physical street address) and has hidden owner details. Whois
http://whois.domaintools.com/*SPAM URL*.com
Now. In the FFmpeg Patent Mini-FAQ not even the FFmpeg authors know what is and isn't patented. That pretty much leaves them open to being "ripped off" by anyone wanting to use their technology.
Then there is this:
Q: Is it perfectly alright to incorporate the whole FFmpeg core into my own commercial product?
A: You might have a problem here. There have been cases where companies have used FFmpeg in their products. These companies found out that once you start trying to make money from patented technologies, the owners of the patents will come after their licensing fees. Notably, MPEG LA is vigilant and diligent about collecting for MPEG-related technologies.
Can anyone say *SPAM URL* is or is not paying royalties to those who want compensation?
- I woudn't trust *SPAM URL* with any purchases. If you want a refund it's probably not going to happen.
- Personally I would leave the legal stuff to the companies using/creating it.
Just my 0.02 cents.
