Licensing ffmpeg

kushal ghosh
Hello,
I want to use ffmpeg.exe for a commercial purpose. Please update me with
the steps so that I dont violate the licensing obligations. I went through
the site but seemed a bit confusing. Do I need to build ffmpeg without
-enable-gpl?
Thanks

I assume you want to "distribute" ffmpeg.exe for commercial
purposes, if you want to "use" it, you only have to agree to the
no-warranty clause.

You will probably have to consult your lawyer.

No, you can choose if you want to distribute binaries based on
FFmpeg source code under the terms of the GPL or under the
terms of the LGPL (which is the default if you do not pass
--enable-gpl to FFmpeg's configure script).
Please remember that you are not allowed to distribute binaries
based on FFmpeg source code if you used the configure option
--enable-nonfree.

I assumed he does mean “use,” as in he is wondering if he is licensed for commercial use of the binary?
If that’s the case, I agree that the no warranty for ffmpeg is pretty much the only thing, but the license for any external libraries it uses might have different stipulations, no?

Yes. I took a published build of ffmpeg and want to use commercially.
I am not very specific in using any of the licensed or patented parts of
ffmpeg.
So basically I want to n=know what the thing to be done so that I can
commercially use it.
I believe only LGPL part of it can be used freely?
Thanks

You need to actually read the GPL and LGPL text (or even the GPL FAQ), that
will tell you what you can do and how. (And what does "use it commercially"
mean, anyway? Sell it? Sell something -containing- parts of ffmpeg?
Something else?)

See https://www.gnu.org/licenses/gpl-faq.en.html and
https://www.ffmpeg.org/legal.html, they're fairly clear.


I'll go out on a limb and say that you should be OK if you distribute a
binary built without "--enable-gpl" or "--enable-nonfree", include or make
available the exact source code used to build that binary, and include the
appropriate copyright/license info (this is all on the "legal" page).


You also need to stop top-posting on this mailing list.

Later,

z!

"Use it commercially" means to use the binary as a part of an commercial
application. So the takeaway is the compile it without those flags. Thanks
for these pointers. I had gone through the Legal page and wanted a second
opinion from experts here as I am not professional legally qualified to
make best sens of it.
Thanks

You may also ship your application with its source code and thus meet the
requirements of the GPL.

For the archives:
Do note that you perhaps meet the requirements of the GPL, you still may have to deal with other licenses if there is non-free stuff involved.
YMMV (IMHO)

Note that we are not legal experts, either (and aren't giving "legal
advice"*). If you need actual legal advice, talk with a lawyer/solicitor.

*that phrase has a specific meaning

Also & again.... please don't top-post on this list.

The "experts" here have written the Legal page, so it
seems unlikely that you'll find another opinion here.
