AAC Streaming Support

Hey Brayden,

Thanks for the request. We'll take a look at what this entails. Today, it's tricky because of codec licensing problems.

Cheers,
RJ Ryan

Which specific AAC profile are you hoping for? With the current state of encoders on linux, LE-AAC is less cumbersome to include than HE-AAC (AAC+), at least from a technical standpoint.

Legally we may not be able to use either, at least not without certain workarounds similar to what we do for AAC files now.

JFYI: libshot2 does *not* support AAC steaming. We are limited to OGG and MP3.

Thought that might be the case - however I thought I would bring it to the Team's attention as I am sure it can be done in the future. Re the legality of bundling the AAC codecs in... similar projects (eg eddcast/oddcast provide off-site third party links where the relevant libraries can be downloaded legally. Phillip: Ideally I would be looking to use HE-AAC.. however I could go with either at this point.

Regards,

Brayden Hulett

 AAC Streaming Support

Status in Mixxx:
 Confirmed

Bug description:
 Just wondering if it's possible in a future release to include AAC as
 a streaming codec when using the Live Broadcasting feature. I intend
 to use Mixxx with an internet radio station and it'd be great if this
 could be added.

Had never heard of edcast myself. Looks interesting:

The libshout fork from the mixlr.com guys might fit in here.
"This fork of libshout 2.2.2 adds support for specifying arbitrary MIME types via shout_set_mime().
This makes it possible to send AAC-encoded audio using a MIME type of "audio/aac" and shout_send_raw()."
https://github.com/mixlr/libshout

Looks like upstream just got a patch for this! https://trac.xiph.org/ticket/1872

I'm taking part in a discussion on icecast-dev about this:
http://lists.xiph.org/pipermail/icecast-dev/2013-June/002195.html

There is a libshout version with AAC support
https://github.com/codders/libshout

An another option would be to adopt the Butt source:
https://sourceforge.net/projects/butt/

This is part of my project for Mixxx during Google's Summer of Code. I have an almost complete encoder implementation here (source and discussion) using libfdk-aac: https://github.com/Palakis/mixxx/pull/4
This works for Recording, but Live Broadcasting requires modifications to libshout, as mentioned above.
libfdk-aac is not required at compile and run time. It is dynamically loaded from a version copied to Mixxx's installation (Windows) or available system-wide (Linux, macOS). Mixxx on Windows can even use libfdk-aac provided with Daniel Nöethen's B.U.T.T encoder by automatically detecting its location.

This could be a nice 2.2 addition.
@Stephane: What is left open to merge this?
