Packaging libopenaptx for pipewire

Hi, I'm the packager of pulseaudio-module-bluetooth-freeworld. It provides AAC, LDAC and aptX for Bluetooth users. I think quite many Fedora users depend on it. There's a lot going on in Fedora regarding pipewire, and a question for me is BT support. The upstream devs of pulseaudio-module-bluetooth- freeworld are also contributing to pipewire, fortunately. See this: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/249 It's literally improving day by day. What seems to be the case is that pipewire can already be built with aptX and ldac support: https://gitlab.freedesktop.org/pipewire/pipewire/-/blob/master/spa/meson.... Distros who don't care about licenses so much like Arch already build it with these as dependencies: https://www.archlinux.org/packages/extra/x86_64/pipewire/ In Fedora this may not be as simple. :) LDAC is not an issue, that's packaged in Fedora. Pali's libopenaptx is not packaged yet: https://github.com/pali/libopenaptx It's LGPL2.1, but apparently contains "derived from ffmpeg 4.0 project" stuff. Is there a chance that this can make its way into Fedora, given that ffmpeg is in rpmfusion due to patent encumberance? If you are sure it can't then I can save myself from waiting for legal reviews etc. :) The other question is then, how to enable aptX in pipewire in case libopenaptx can only be packaged in rpmfusion?  Only by shipping some pipewire-free which is essentially pipewire with added rpmfusion dependencies? Or should we start encouraging upstream to create some modular system for this, so that these codecs/BT support are in more easily replacable libraries? (Like pulseaudio-module- bluetooth is) I appreciate your help on this! Best regards, Greg
