According to bluez-alsa's home page, aptX is supported via the extra library `openaptx` by the same author. It would be nice to have. Please note, it looks like openaptx: * uses reverse-engineered code => possible licence issues; * relies on ffmpeg's aptX support which seems not available in Gentoo's ebuild. An alternative might be Pali's `libopenaptx` (see also Bug 758377), though that's work in progress: <https://github.com/Arkq/bluez-alsa/pull/356>. Reproducible: Always
This looks like it definitely would cause license issues. CCing license team.
Looks like the project is distributed under the MIT license. If the algorithm is affected by software patents, then it cannot be distributed in binary form (at least not in countries where it is patented). Commercial use may also be problematic. IIUC distribution of source code shouldn't be a problem, so the only thing needed would be a bindist restriction. Disclaimer: I am not a lawyer. This is not legal advice.
Tried with this ebuild: ``` EAPI=7 inherit cmake-utils DESCRIPTION="reverse-engineered apt-X audio codec" HOMEPAGE="https://github.com/Arkq/openaptx" if [[ ${PV} == "9999" ]] ; then inherit git-r3 EGIT_REPO_URI="https://github.com/Arkq/${PN}" else SRC_URI="https://github.com/Arkq/${PN}/archive/v${PV}.tar.gz -> ${P}.tar.gz" KEYWORDS="~amd64 ~x86" fi LICENSE="MIT" SLOT="0" ``` And got aptX working only when built with `MYCMAKEARGS="-DWITH_FFMPEG=ON" emerge openaptx -v1` (and `EXTRA_ECONF="--enable-aptx" emerge -v1 media-sound/bluez-alsa`). Without `-DWITH_FFMPEG=ON` I got a loud annoying noise instead of sound. Tried with libopenaptx and `EXTRA_ECONF="--with-libopenaptx"` also, but aptX wasn't detected at all.
openaptx is in Gentoo tree now

This is in the live ebuild for now because we only have media-libs/libopenaptx and support for that lib is not in the 3.0.0 release. Once bluez-alsa rolls a new release, aptx support will be available there.
