VisualOn AAC Encoder Options

[Nic]

Hi,

Apologies if I have missed it, but has the VisualOn AAC Encoder been checked out by you guys? It's recently been added in as an optional encoder for ffmpeg, but not sure how it compares to the great AAC encoders (one imagines it fares better than ffmpeg's current internal encoder)

The README of the library says:

VisualOn AAC encoder library

This library contains an encoder implementation of the Advanced Audio
Coding (AAC) audio codec. The library is based on a codec implementation
by VisualOn as part of the Stagefright framework from the Google
Android project.

Anyway, couldn't get my current MSYS/MinGW environment to compile it from https://github.com/mstorsjo/vo-aacenc so I just whacked it all in Visual Studio 6.

If you're in the mood grab it from (Edit: patent violation removed) and give it a test. Its little test app is simple and old school so writes out to ADTS AAC files rather than MP4. Usage Example: vo-aacenc.exe -r 128000 RhymePays.wav RhymePays.aac

I doubt it's great - but would be interested to know how far some good ears consider it behind the mighty Neros and Apples of this world....

Cheers,
-Nic

I did compile an ffmpeg that is using it (for OSX), but no abxing so far.

Try dogies or rawhide ( http://www.ff123.net/samples.html ) or apocalypse. Easy to abx even at 320 kbps.

Nice, so it does not really make sense to use VisualOn to replace the internal ffmpeg AAC encoder.

The internal AAC encoder (-acodec aac -strict experimental) seems to be even worse (according to the results at http://d.hatena.ne.jp/kamedo2/20110430/1304181738)
