Compile ffmpeg for GPL use on Yocto

From what I understood here, if I compile with the flag --enable-gpl, ffmpeg can be added in a commercial product. In the recipe, there is: PACKAGECONFIG[gpl] = "--enable-gpl,--disable-gpl"

Thus, I created a ffmpeg_%.bbappend containing:

PACKAGECONFIG_append ="gpl"

But it seems I still have to put a value in LICENSE_FLAGS_WHITELIST, most likely commercial. Is it a mistake from me or is it not handled properly by the main recipe?

Thanks

No, it's not a mistake.

The PACKAGECONFIG[gpl] = "--enable-gpl,--disable-gpl" just adds a way to enable/disable building GPL-licensed parts of ffmpeg. It has nothing to do with whether you can use the result in a commercial product.

By setting LICENSE_FLAGS_WHITELIST_append = " commercial_ffmpeg", you're telling the buildsystem that you're allowed to build and use ffmpeg. That can be due to you having acquired a commercial license (or licenses), that you'r in a jurisdiction where you don't need commercial license(s), etc...

Note that in this case, these two PACKAGECONFIG[gpl] and LICENSE_FLAGS_WHITELIST are orthogonal, they have nothing with each other to do.

The LICENSE_FLAGS_WHITELIST is there to protect you, from adding things that might require commercial licenses by mistake / unknowingly.
