Hi,

I’m a developer of a gstreamer plugin for specific chip, may I ask some license questions of gstreamer plugin?

1) The gstreamer plugin shall follow same license with gstreamer (LGPL v2), is it true?

The GStreamer library license has  been chosen specifically to allow plugins with a range of different licenses including proprietary licenses.

So it's perfectly fine to write and ship proprietary plugins, for example. And some hardware vendors do that already.

However, if you want to propose your gstreamer plugin for inclusion in the upstream GStreamer project, we will usually ask for it to be licensed LGPL v2+, MPL v2, BSD or MIT.


2) If 1) is no, the gstreamer plugin license can be other open source license like “Apache 2.0 License”, “BSD-2-Clause”, “BSD-3-Clause”, “MIT license”?

Correct.


3) If 1) is no, the gstreamer plugin license can be non-open source or property license?

That is also correct, and there are quite a few companies shipping proprietary GStreamer plugins (hardware vendors and others).

Disclaimer: IANAL, and these are all things you should ask your lawyers about :)

There are some notes on licensing our FAQ<https://urldefense.com/v3/__https:/gstreamer.freedesktop.org/documentation/frequently-asked-questions/licensing.html?gi-language=c__;!!PeEy7nZLVv0!iCVfXxdUnfSQrlkVllY7x5D6rs7oWE6_Leh73eZKcjWoUNaaeRj6ZHY49l3BD6yUQiAJsVx_Uq4$> as well but they don't address your questions specifically.

Cheers
 Tim
