libfslvpuwrap license question

[Carlos Rafael Giani]

Hello,

in my gstreamer-imx project, I need to work around certain problems the 
libfslvpuwrap library (also called the "VPU wrapper") has. However, the 
efforts to do so are considerable, and it would be much better (and 
cleaner, more robust) to simply fix that library.

On one hand, the source is available, so I can patch it. On the other 
hand, the licensing situation is unclear. Can I just copy 
vpu_wrapper.c/.h , patch these, and keep the patched files in the 
gstreamer-imx repository (this project is LGPLv2 licensed) ? If not, I 
will have to start thinking about a reimplementation of several VPU 
wrapper parts, and use the underlying imx-vpu interface directly instead.

Carlos

Yes you can fork it. The LGPLv2 license is quite permissive and also
your code is license compatible.

Sorry but now I double check it and I have said the wrong thing for you.

The vpuwrap is indeed FSL proprietary code; to avoid any complications
I'd say you to add a header file, and a counterpart .c file, on top of
it to 'hide' its issues and avoid any license complication to your
code.

Sorry but I have read your message as the vpuwrap was LGPL, so my
misunderstanding.
