@hikari Yes, my recollection from way back was that it was just there in case you have a format constraint that something can only decode AAC, not with an intent that it actually be useful.

@hikari you can use Android's AAC codec with -acodec libfdk_aac if your FFmpeg is built with it (most distributions are not, as it is under a custom license which is incompatible with the GPLv3)
on macOS you can use the system AAC codec with -acodec aac_at (there's also hacks available to build this support on windows using itunes' build of it)

@hikari note that Fedora's position is that FDK AAC is GPL-compatible iff it is patched to remove all code encumbered by non-expired patents. this appears to explicitly diverge from Debian and the FSF's position

@leo oh i did not know there was a dispute about how free fdk-free is! could you give me pointers to more info?

@hikari brief post on the fedora legal mailing list https://lists.fedoraproject.org/archives/list/legal@lists.fedoraproject.org/thread/OVW25JRWOKOLVMW3XGUX7E4OXFUR2RCG/
armchair lawyer argument on bugzilla https://bugzilla.redhat.com/show_bug.cgi?id=1501522

@hikari Debian apparently ignored the patent part and took issue with other parts of the license https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=694257
and the FSF mentions the patent clause separately, and doesn't clarify their reasoning for it being GPL(v2)-incompatible

@hikari Debian switched to packaging fdk-aac-free but still puts it in non-free. despite this there's an LGPLv2.1 package in contrib (gstreamer1.0-fdkaac) with a hard dependency on it

@leo thanks a lot! i was curious because for a long time i'd been considering integrating it into touchHLE (in the end i integrated something else)

@hikari Release notes claim that ffmpeg improved its encoder in 5.0 (2022), so I don't think it's still supposed to be like that.

@hikari is it possible to get a better one?

@0x2ba22e11 i think so but don't know the details. supposedly apple's encoder on macOS and (on Windows) in iTunes is much better

@hikari wow, i had missed this https://git.videolan.org/gitweb.cgi/ffmpeg.git/?p=ffmpeg.git;a=commit;h=d163e0ecbcae10745a86a7142d9194d484fdbcce

@hikari @whitequark If you’re on a Mac, you can use -a:c aac_at to use the AudioToolbox codec which is both quite good and quite fast

@resistor @hikari @whitequark you're welcome
