UsEac3to v1.3.3: a different GUI for eac3to

Like I say you before:

I can't help you with commercial directshow Nero Audio Decoder filters but the GUI UsEac3to can help you using ffmpeg.exe (must be in eac3to/UsEac3to/Encoders folder)

If you want downmix 5.1 to 2.0 and/or normalize an aac you need two steps (eac3to or AviSynth needs also 2 steps always):

Step 1:
1) Load your file and click in 'Add' FFMPEG More parameters. See first attached image.

2) In the new window search and select the ffmpeg filter '51-20v'. If not exist in your Vid_enc.par copy the text in the image or other downmix metod.
If you only want normalize leave only:
-af "volumedetect"

3) Close the window with 'Done' and the ffmpeg filter are now in the COMMAND LINE PARAMETERS

4) See the image 2. Click in 'A/V Recode'

5) Select the track desired in the 'map:X'

6) Select 'Add to DEC' to include the ffmpeg filter.

7) Select 'Decode...' to 'null'. When this run don't create files then is very fast.

8) Run and see:

...
video:0kB audio:485504kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown
[Parsed_volumedetect_1 @ 000002308e4f3400] n_samples: 248578048
[Parsed_volumedetect_1 @ 000002308e4f3400] mean_volume: -36.9 dB
[Parsed_volumedetect_1 @ 000002308e4f3400] max_volume: -9.7 dB
...

Copy the max_volume value.

Step 2:

1) Edit the COMMAND LINE PARAMETERS replacing 'detect' with '=9.7dB' to obtain:
-af "pan=stereo|FL=.3694c0+.2612c2+.3694c4|FR=.3694c1+.2612c2+.3694c5, volume=9.7dB"

2) Repeat the previous 4), 5) and 6)

3) Now, instead 7) 'decode to null', select the desired output format and quality or bitrate.

About the recommended qaac settings:

-V, --tvbr <n> AAC True VBR mode / quality [0-127]
-v, --cvbr <bitrate> AAC Constrained VBR mode / bitrate

Use only the --cvbr when you need a fixed size, if not use your desired quality (for me -V 99 is transparent, 80 is good to save space)
Talking about standard stereo movie tracks (many dialogs and silences, without many music of effects) -v 192 is waste space.
For instance using -V 99 over a movie stereo track I obtain: VBR min./avg./max. : 4 / 143 / 406 Kb/s.
Go until 406 Kb/s when need it, but the average remain at 143.

I'm not sure about "low,med or high?", maybe the quality?

-q, --quality <n> AAC encoding Quality [0-2]

Use always the default 'high', the process is very fast you don't need save time with less quality.

I don't know what this strange inscription is due to, but I show it with a photo. The same error appears with StaxRip v.2.29.0 x64.

Like I say to madshi longtime ago that WARNING, not a ERROR, is useless, forget it.

24 fps is a normal fps.

Hi, hopefully someone can help me. When demuxing files with Japanese in the filename i get the language code 'Jap' I didn't think this would be a problem but when remuxing the files with mkvtoolnix I have found a problem - when deriving the language 'Jap' isn't recognised. The only code recognised is 'Ja' and 'Jpn'. Can eac3to demux to ja or jpn? I'm using the eac3to gui. Thankyou

[tebasuna51]

The names generated by the eac3to demux put the full language names and comments, for instance:

...Japanese, 'Japanese'.srt
...Korean, 'Korean'.srt
...Spanish, 'Latin America Spanish [SDH]'.srt
...Norwegian, 'Norwegian'.srt
...Polish, 'Polish'.srt

My UsEac3to GUI put only the first 3 caracters to identify the track and can't convert it to the exact language codes.
