Helix fixed-point AAC/Plus decoder Win32 bin Options

[Enig123]

As kurtnoise requested, I asked CML to compile this win32 binary.

It can only decode raw AAC/Plus files to wav or PCM.

The cvs contains the whole project, so it's quite easy compared to compiling of Helix mp3 coder.

Hi

I followed below method for decoding a file using helix-aac-decoder.

1. Downloaded the source code from CVS.
CVS path: cvs -z3
-d:ext:swathijakkam@cvs.helixcommunity.org:/cvsroot/datatype co aac/codec/fixpt/decoder

2. Opened the aacdec.dsw in visual studio 8.0
File Path: aac->codec->fixpt->decoder->real->projects->visual.

3. I ran the project without any modifications.

Then I got exception while decoding an AAC+ files.
Exception message: "aacdec.exe has triggered a breakpoint".

I got this exception in DecodeSectionData() at ASSERT(sfb == maxSFB); in noiseless.c file.
And I am getting error value-15 ( ERR_AAC_NCHANS_TOO_HIGH) at console output.

Console output is :

0 bytes in 0 Free Blocks.
37072 bytes in 2 Normal Blocks.
0 bytes in 0 CRT Blocks.
0 bytes in 0 Ignore Blocks.
0 bytes in 0 Client Blocks.
Largest number used: 35396 bytes.
Total allocations: 37072 bytes.
Error - -15

Memory leak test: no leaks
Memory integrity test: okay

FYI, I downloaded live stream of a radio station on Shoutcast to a file which is in AAC+ format.
I used this file to decode. While decoding I got the exception.

But I can able to decoded AAC file after converting that AAC+ file to AAC.

Thank you in advance.

Best Regards,
Swathi.
