aac+ encoder patch for ffmpeg

HOWTO:

Follow steps below to patch FFMPEG that enables aac+ encoding.

You have to install libaacplus first!

Here is newer-patch code for debian/ubuntu linux:

$ svn checkout svn://svn.ffmpeg.org/ffmpeg/trunk ffmpeg -r 23548$ wget http://tipok.org.ua/downloads/media/aac+/libaacplus-simple-sample/ffmpeg... $ patch -p1 <ffmpeg-aacp.09062010.diff
$ ./configure --enable-libaacplus $ make # make install

Here is old-patch code for debian/ubuntu linux:

$ wget -O ffmpeg.tar.gz "http://git.ffmpeg.org/?p=ffmpeg;a=snapshot;h=124fefe867ef023a89ca4f4cc76e700342286b0d;sf=tgz" $ tar -xvzf ffmpeg.tar.gz $ cd ffmpeg $wget -O libswscale.tar.gz "http://git.ffmpeg.org/?p=libswscale;a=snapshot;h=1842e7d1cc122feea92dcd2d9a9a1adfb397aa24;sf=tgz" $tar -xvzf libswscale.tar.gz
$ wget http://tipok.org.ua/downloads/media/aac+/libaacplus-simple-sample/ffmpeg... $ patch -p1 < ffmpeg-aacp.diff $ ./configure --enable-libaacplus $ make # make install

CHANGELOG:

14.04.2009:

Stereo encoding bug fixed (encoded sound quality is much better)
Mono encoding implemented.
Audio specific config bits changed (now flash player can play aac+ "m4a" files, produced by ffmpeg)
Patch updated for latest FFmpeg

ENCODED SAMPLES:

sample32.aac
sample32.mp4
sample64.aac
sample64.mp4
source.mp2 (not aac+ encoded) - source file

Hey,

how can I switch SBR, V2, V1? Is there pass1 and pass2?

Thanks.

it depends on selected bitrate.
If less and include 44Kbps - then SBR v2 used.
In other cases - SBR v1.

It seems aacplus doesn't want to go over 64kbps... Any way to force it?

Submitted by tipok on Tue, 07/21/2009 - 11:43.

3GPP implementation does not support bitrates over 64 kbps. If you want to encode with bitrate over 64kbps, it's better to use faac encoder.Here is image, that describes quality of he-aac he-aacv2 and aac-lc codecs depends on bitrate:

Yes, i tested various variants of audio specific config bits, and i see that all 3 last bits have to be zero, then flash player can play it. So I fixed if at this patch. Here is my working test file. I installet this file url in JW-flv player wizard

P.S. Just redownload patch, I fixed it now.

Hi, I really appreciate your work on libaacplus. Thank you! However I still can't get the ffmpeg finding the libaacplus...
I have installed libiconv,gettext,glib and pkg-config. But keep getting this error during libaacplus autogen:

configure.ac:48: error: possibly undefined macro: AC_TYPE_INT16_T
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
configure.ac:49: error: possibly undefined macro: AC_TYPE_INT32_T
configure.ac:50: error: possibly undefined macro: AC_TYPE_INT8_T
configure.ac:51: error: possibly undefined macro: AC_TYPE_UINT16_T

Is it related to x86_64 environment?

these macros were introduced in autoconf version 2.59-5 (or 2.59c). Install fresh autoconf (>= 2.59-5) to your system.

No, it's related on autoconf version.

You got to install libiconv,gettext,glib and pkg-config and then compile libaacplus and then ffmpeg will find it.

Hello,

I loved your work on the aacplus reference encoder.. I also used the ffmpeg patch for the integration of it into ffmpeg so far so good :)

I just wanted to know if there is a way to enable it for 6ch encoding?

Submitted by tipok on Wed, 04/01/2009 - 12:30.

This library based on 3gp implementation, that can encode only 1 or 2 channels. So there's no way to encode 6ch.
