Summary0004316: f_aac.dll: Wrong Channel Mapping with 5.1 MP4 files
DescriptionAs reported here:
http://www.mediamonkey.com/forum/viewtopic.php?t=25052

Mediamonkey maps the channels of surround MP4 files wrong.

way to reproduce:
get the 6 channel test file:
http://download.microsoft.com/download/winmediatech40/Utility/1.0/W98NT42KMeXP/EN-US/6channel.exe
encode it with free nero aac encoder, playback the encoded file. Channels are mapped wrong.

I attached the encoded file on our FTP (6_channel_ID2.mp4), so that anyone could easily reproduce the problem.
TagsNo tags attached.
Fixed in build1135

1. Does f_aac_codec play it right?
2. Does QuickTime play it right?
3. If so, can you fix f_aac.dll?

Re: 1. By using f_aac_codec it throws AV.

I'm going to study more once I have a time.

The 5.1 channels are mapped correctly in f_aac.dll now.
