Here's another bug I found, which is probably related to the bug I reported in this post some weeks ago.

It seems that on RAW AAC ADTS files, the in_mp3.dll is mixing up MPEG-2 AAC and MPEG-4 AAC header structure in the Info display section.

It's no problem of playback, it's only a problem of the display. Following examples:
MPEG-4 AAC, raw ADTS file.
"MediaInfo" (third-party tool) displays it as MPEG-4 AAC.
code:
General
Complete name : D:\DOWN\out4.aac
Format : ADTS
Format/Info : Audio Data Transport Stream
File size : 2.47 MiB
Duration : 4mn 25s
Overall bit rate : 78.1 Kbps
Audio
Format : AAC
Format/Info : Advanced Audio Codec
Format version : Version 4
Format profile : LC
Format settings, SBR : Yes
Format settings, PS : No
Muxing mode : ADTS



"But Winamp displays it as MPEG-2 AAC":



In the opposite, the same file patched to MPEG-2 AAC is displayed as "Version 2" in MediaInfo, but displayed as "MPEG-4 AAC" in Winamp:

code:
General
Complete name : D:\DOWN\out.aac
Format : ADTS
Format/Info : Audio Data Transport Stream
File size : 2.47 MiB
Duration : 4mn 25s
Overall bit rate : 78.1 Kbps
Audio
Format : AAC
Format/Info : Advanced Audio Codec
Format version : Version 2
Format profile : LC
Format settings, SBR : Yes
Format settings, PS : No
Muxing mode : ADTS



See second screenshot:


It's, again, a small and "cosmetic" bug, but it would be great if you could fix it!
