ERROR: unsupported profile

[HironoKenta]

Hi nu774, I'm running a Kubuntu 23.10 and I having issue trying to encode HEv1 and HEv2 files, it also return the same error for ELDv2 profile.

I replaced the fdkaac v1.0.0 of repos to a 1.0.5 and a master compiled from sources, but nothing changes.

"unsupported profile" error happens when the encoder (libfdk-aac) refused only by the AOT number (5 or 29). Perhaps ubuntu's package maintainer has decided to build / distribute libfdk-aac without SBR support due to some patent concerns or something. Ask them.

Or you could build libfdk-aac from the source and static link to it.

Well I solved it replacing the /usr/lib/x86_64-linux-gnu/libfdk-aac.so.2.0.2 with self compiled /usr/local/lib/libfdk-aac.so.2.0.2 from mstorsjo's source (make install rightfully don't put it into /usr/lib/, but seems this lib superimpose over the /usr/local/ one).

I can't remove libfdk-aac2 package coz doing it will broke pipewire dependency.

I hope someone will be helped by this bugreport and I thank you for your time and support. (still upset Ubuntu's mantainers didn't add a reference to the changes in descriptions/names)
