MPEG2 patents expiring

Wed Jan 03, 2018 3:28 pm

I'm wondering how will MPEG2 decoding be handled now that the MPEG2 patents are finally expiring? Will the codec be unlocked automatically with new versions of Raspbian?

I think you'll have to wait until 15th Feb and see what happens.

Any predictions? I'm working on a project where we'll need up to 1000 RPi's with Omxplayer MPEG2 capability, and it's a pretty complicated undertaking to unlock them since there's no way to fully automate the task due to the way the license purchasing works. It would be a huge relief and save a lot of money in production time, software development, and licensing fees if we could avoid all that.

Making the mpeg2 codec free would be a nice "pi birthday" gift to all pi owners later this month ...

I don't see how having the patent expire necessarily, magically, makes anything free.

Vendor s of patented software can still continue to charge a license fee for it even if the patents expire. We can't just start using it, copying it and distributing it will nilly. It's covered by copyrights. Protected by the DMCA and so on. Then there are NDA's and such to worry about.

It does mean, however, that we are free to create new implementations of the patented idea if we like. I nice little project for somebody.

It is mentioned also here http://www.mpegla.com/main/programs/M2/ ... tList.aspx
Please note that the last US patent expired February 13, 2018, and patents remain active in Philippines and Malaysia after that date.
And there is also link to 24 pages long pdf with word 'expired' on almost all lines except few first named MYxxx and PHxxx.
