Nero HE-AAC v2 => "no file outputed"

Post by boardersparadise » Sat Mar 13, 2010 6:51 am

Hi. There seems to be a problem with the Nero encoder. My input file is valid, because MC manages to encode it into a variety of other formats.

(1) mkv/h.264/Nero HE-AACv2: "no file outputed"
(2) mkv/h.2647MP3: works (this shows us that the error does not concern the video encoding)
(3) default/--/Nero HE-AACv2: "no file outputed" (I disabled video, in order to isolate the error, and chose default container)

This shows us that the problem concerns the Nero HE-AAC v2 encoding.

MediaCoder 0.7.2.4582.

Don't ask me why there are references to LAME and h.264 when none of them are used in (3).
The following are my settings for (3):

Code: Select all

I tried the following as "source":
  • "auto select"
  • default
  • mplayer
  • MEncoder
  • FFmpeg
  • waveform file
selections 1-5 resulted in "no file outputed"
selection 6 resulted in white noise output (wat is "source:waveform file" by the way?)

(edited by admin)

When I select 3GP AAC+ instead, I get the error "Error loading 3GP AAC+" , then "no file is outputed" and error code #12-
When I select CT AAC+ I am told that I need additional .dll files. Where do I get them from?

So in conclusion,
none of the 3 different AAC v2 implementations work for me :(

I updated to 0.7.3.4612 and I get the very same errors as posted above.
I have a hard time understanding this, because AAC is certainly one of the most popular codecs, so why would they not work out-of-the-box ?


I just found that my report seems to be confirmed here:
Entity wrote:Were you converting from WMV? I can't get anything to go from WMV -> MP4 using HE-AACV2 (HE-AAC seems to work fine). I get "The testing phase has failed" (F6 shows a simple "could not open file" message with the name of the MP4 it is apparently trying to create).

Make sure sample rate is > 32000.
When things work together, things work.

Hi Stanley.

(post edited)

If you are refering to the output sampling rate ("Resample" button), I always left that at "original" for my Nero HE-AAC v2 testings.
If you are refering to the input sampling rate (of the source file), I would have thought that any sampling rate should be supported.

But for some reason, your hint may be relevant for the problem I reported, because the input test files had sampling rates < 33 kHz, and my new tests with >33 kHz worked out just fine.

What would you suspect is the problem?

HE-AAC format is designed to be only compatible with sample rate > 32khz.
Actually it is meaningless and no benefit to use HE-AAC for audio with sample rate < 32khz. Just use LC-AAC.
When things work together, things work.
