A_AAC/MPEG4/LC Say WHAT???

[steban1990]

:mad:Ok, hello guys, here attempting to solution a problem with some kind of audio codec I never seen before and I have always wanted to ask this but I tend to solve thing by asking god google first, but this time no solution.

It is with this kind of audio stream codec "A_AAC/MPEG4/LC" I´m getting errors with and each GUI I use for encode don´t even recognize it, for example:

Staxrip with

So I tried to go by separate process, achieving getting the video right with staxrip, but a mess with the audio stream, tried with vidtualdubmod by extracting it and saving in a WAV file but useless, tried encoding it to mp3 but I always get the encode classic syncing audio problem and the worst one, it is synced correctly a few minutes and then puff the mess and I guess it is because mp3 converters compress the file too much,...:confused::devil:, I´m starting to get tired, why The heck do people use this kind of codec anyway(it is like to make things harder, better quality in the audio? who knows)oh well, had encode this thing like 5 times now and nothing.

Well continuing with, as you can see at the audio track apartment in the quote, I have got this " Codec ID : A_AAC/MPEG4/LC" And, I wanted to make some question about. Only thread I got a hold about this topic is this:
forum.videohelp.com/threads/227397-A_AAC-MPEG4-LC-SBR-say-what ...But even trying most of what they said, nothing.

So guys, do you know any method to convert this kind of audio stream codec to any other audio stream type, mp4, Ac3 without compressing much data, just getting it to another contaier would do well I guess(Hope to avoid syncing problem with that)?, etc any advice would be hugely appreciate, have this happened to you? if yes how did you resolve it? if not any advice would be welcome as well.

Well here is the complete source specs, hoping some tips 0_0

There is some demux GUI called mkvcleaver or something, next StaxRip version soon to be released will demux it.

Love your gui and I wanted to do this question long ago, but I decided to do some research.

Not much source use this kind of codec, but I wanted to know,w why do people use it anyway, better Audio quality or something.

Well expecting hugely much that update now, my huge thanks for both your GUI and the answer.:):p

Closed and struck for rule 6 violation.

That rule 6 you got on March 13 just didn't wake you up, huh?
