Hi,

1. Would you consider adding support for qaac codec?
2. Is there an option to change video frame rate (e.g. from 25 to 24) without encoding? I couldn't find one.
3. A drag-and-drop option for file specification would be very helpful.

Thanks

[ProWo]

1. Would you consider adding support for qaac codec?

qaac codec is not included in ffmpeg, and because clever FFmpeg GUI is built on top of ffmpeg only, the use of qaac is not provided.


2. Is there an option to change video frame rate (e.g. from 25 to 24) without encoding? I couldn't find one.
No.


3. A drag-and-drop option for file specification would be very helpful.
What exactly do you mean by file specification?

Hi ProWo,

I had a little job to do with this today,

I wanted to convert a 7.1 TrueHD track to AAC 7.1, which this did, took a while, but that's ok.

However, the channel mapping changed considerably from original.

If you would like to know how it changed, please go here :-

https://forum.doom9.org/showthread.php?p=1977775#post1977775

Cheers

[tebasuna51]

I use MediaInfo channel names (https://mediaarea.net/AudioChannelLayout).

Here (https://developer.apple.com/documentation/coreaudiotypes/audiochannellayout/1572101-audio_channel_layout_tags) show 3 options for AAC Defined Layouts 7.1:

AAC_7_1: C L R Ls Rs Lw Rw LFE
AAC_7_1_B: C L R Ls Rs Lb Rb LFE
AAC_7_1_C: C L R Ls Rs Tfl Tfr LFE

The default one is the first and some aac encoders (Nero, ffmpeg, fhgaacenc) output always that channel layout using this WAV to AAC channel equivalence:
FL/FR -> Lw/Rw
FC/LFE = C/LFE
BL/BR -> Ls/Lr
SL/BR -> L/R
Using ffmpeg like decoder recover the correct layout sending a message:
[aac @ 00000215e4c73d80] Assuming an incorrectly encoded 7.1 channel layout instead of a spec-compliant 7.1(wide) layout, use -strict 1 to decode according to the specification instead.


If you want the standard 7.1 must use qaac or fdkaac than output the correct AAC_7_1_B: C L R Ls Rs Lb Rb LFE

Hi TDS,
I checked this and just now encoded a TrueHD 7.1 audio stream to AAC 7.1 using clever FFmpeg-GUI.
Mediainfo shows the differences in channel layout you showed, but when I compare the files in Audacity, the channels are arranged exactly the same.
Maybe a problem of Mediainfo?
Compare yourself (see attached picture).
On the left the original TrueHD 7.1 file, on the right the converted AAC 7.1 file.

[tebasuna51]

...but when I compare the files in Audacity, the channels are arranged exactly the same.

Audacity can't decode itself AAC, it uses ffmpeg and maybe silent do:

"Assuming an incorrectly encoded 7.1 channel layout instead of a spec-compliant 7.1(wide)"

But MediaInfo now is correct, ffmpeg encode the standard 7.1 to a non-standard 7.1 channel layout.

Use qaac or fdkaac if you want the correct channel layout 7.1, without problems with 5.1.

So what does this really mean, does someone need to look into this a bit deeper ??

Fortunately for me, tho, I don't use 7.1 anyway, it was just a test, as a question was asked on another forum.

[tebasuna51]

The problem is how decode your player an AAC 7.1, strictly it must decode ffmpeg aac 7.1 like the second image in my post and can output a wrong channel map.

To avoid problems encode 7.1 with qaac (the recommended and free AAC encoder) or fdkaac, when the source is the image 1 the decoded output is the same.

Fortunately for me, tho, I don't use 7.1 anyway, it was just a test, as a question was asked on another forum.

The same for me, my AVR is configured like 5.1.2, and only use aac 5.1,

[ProWo]

Use qaac or fdkaac if you want the correct channel layout 7.1, without problems with 5.1.

I wanted to try that, but qaac does not recognize the truehd 7.1 file.

D:\Freeware\Audio\qaac\x64>qaac64.exe O:\rip\mainmovie\Audio_dolby-spheres-TrueHD_7.1_1_A_extracted.mka

ERROR: Not available input file format

Can you show me the exact command line?

[tebasuna51]

You need ffmpeg like decoder:

"C:\Portable\0\ffmpeg.exe" -i "input.thd" -acodec pcm_s24le -f wav - | "C:\Portable\0\qaac.exe" -V 91 --ignorelength --adts --no-delay -o "output.aac" -

Thanks, this worked, but the new created file cannot be opened by foobar or audacity.

[tebasuna51]

You are rigth, seems problems of these soft's with ADTS AAC format, without problems in MP4 container:

"C:\Portable\0\ffmpeg.exe" -i "input.thd" -acodec pcm_s24le -f wav - | "C:\Portable\0\qaac.exe" -V 91 --ignorelength --no-delay -o "output.m4a" -

[ProWo]

It's not the container, the adts switch is problematic.
Thanks anyway.
What software can display the effective AAC channel layout without the decoder changing it (like ffmpeg)?

[tebasuna51]

It's not the container, the adts switch is problematic.
Yes, because the adts header have a field for NumChannels not for a MaskChannel. The qaac and fdkaac put '0' in that header field and MediaInfo and many decoders read that like AAC_7_1_B: C L R Ls Rs Lb Rb LFE

If NumChannels is '8' is read like AAC_7_1: C L R Ls Rs Lw Rw LFE

I don't know where is documented that workaround.
What software can display the effective AAC channel layout without the decoder changing it (like ffmpeg)?

To display audio we need always decode it, to wav or equivalent uncompressed formats. Then your question is what decoders output wav files with waveformatextensible header and correct channelmask.

After decode you need a wav editor than read the channelmask correctly
The correct channelmask for a AAC_7_1: C L R Ls Rs Lw Rw LFE must be:
255 (FL FR FC LF BL BR FLC FRC)

I recommend qaac to Decode .aac or .m4a:

"qaac.exe" -D -b 24 -o "aac_.wav" "input"

Now you can display "aac_.wav" with Audacity, Wavosaur, GoldWave or Audition

Hi ProWo,

I grabbed this earlier, and I just used it to convert an audio track, and when I clicked "Encode", the % scroll bar went straight to 100%, but was still processing, as it's showing the size, time, bitrate & speed info.

Also, the "Encode" button seems to cover the "LoudNorm" option.

EDIT:- I'll take back the comment on the % scale, it must have been the file I imported, but the other comment is still relevant.

[ProWo]

Hi ProWo,
also, the "Encode" button seems to cover the "LoudNorm" option.
This happens when you use a screen scaling of >100%
