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

Very interesting Garf - I was not aware of that, it does looks very suspect! How disappointing....especially as it's related to "do no evil" google.

Hmm... even if it turns out that the code is not licensed properly, it might happen that Google was not aware of this (e.g. if the vetting process, if there is one, is done in a way that might not involve Google proactively doing the IP check)

I'm not saying scenario is impossible - just that there might be few possibilities, apart from the "do no evil" Google being somehow implicated in this

But, in any case, if it turns out that the code is not licensed properly - it will not be a good PR for Android for sure.
