@ Prowo

When you drop files into the mux grid, an existing movie title is displayed. If there is no title, you want to automatically insert the file name as the title. That's good.
Can you add a checkbox before the movie title? If it is checked, the movie title is muxed, if not, it is not. However, they are always displayed on the mux page.

When you drop files with different file names into the mux grid, the stream selection automatically switches to first. That makes sense. However, the movie title of the last file dropped is then displayed. See screenshot. That is confusing.
Wouldn't it be better if the movie title was only displayed for the selected video stream with the lowest index number?

is there any decent, free, no email, no account, no signup file sharing service out there ??

At scene changes, tests:

On average, the 15 minute F1 sample has every 2 seconds an I frame.

v3.4.7
When I use treshold 0,35, I get 20 chapters, 12 of them between minute 12:53 and 14:34

12:53
12:58
13:10
13:15
13:25
13:30
13:31
13:41
14:11
14:16
14:34
14:43

The shortest one is only 1 second long.

v3.4.7.01
When I use treshold 0,35, I get 15 chapters, 7 of them between minute 12:53 and 14:34

12:53
13:10
13:25
13:41
14:11
14:34
14:43

The shortest one is only 9 seconds long.

So it's getting better, but there are still too many short chapters in a minute and a half.

## AAC Codec Channel Information Storage

In the AAC codec, channel information is stored in the audio stream's
audio object type (AOT) and channel configuration field within the Audio
Specific Config (ASC) or stream header. Specifically:

| Component | Channel Information Storage |
|-----------|------------------------------|
| Location | Audio Specific Config (ASC) |
| Field | Channel Configuration |
| Encoding | Predefined numeric values |
| Standard | ISO/IEC 14496-3 specification |

### Channel Configuration Mapping
The channel configuration is typically represented by a numeric
value that indicates the channel layout:
- 0: Specific configuration (defined in the audio specific config)
- 1: 1 channel (mono)
- 2: 2 channels (stereo)
- 3: 3 channels
- 4: 4 channels
- 5: 5 channels
- 6: 5.1 channels
- 7: 7.1 channels

### Technical Details
The channel configuration is part of the audio object type (AOT) in the stream's metadata.
When decoding an AAC file, codecs and media players read this field to understand the audio
channel layout and properly decode the audio stream.

How do I convert ASS subs to PGS/SUP in Clever FFMpeg Gui. FFMpeg has that feature.

[ProWo]

Have you managed to download and ...... open the audio file in Clever??

Yes and no.
I was able to extract the aac stream from the mp4 container, but it has probably been deliberately manipulated.
ffmpeg cannot do anything with the stream.
I think that the first frame is compromised and the following ones are OK.
This explains why the mp4 can be played on some players that do not strictly adhere to the standard.

EDIT:
Found a way to repair it:

1) extract the aac
ffmpeg -i AAA.mp4 -c copy output.aac

2) Fire up VLC player, click Media, Convert/Save.
Click add to add your aac file, click Convert/Save.
On profile, click the Create a new profile button, set wav, name it pcm.
Select this new pcm profile, click destination file, browse.
Insert the name of your new output file and click start.
Wait until is finished.

3) Convert this wav to whatever you want and mux the result with your videostream.

I am suspecting some sort of Apple/iTunes protection.

Clever 'scan for errors' shows this on the audio track

v3.4.7.02 feedback

The file name -> movie title works great .. thank you for adding it in.

Can the title checkmark be defaulted to on? you can still change the
title text for every file name while the checkmark is defaulted to ON.

Which brings me to the elephant in the room .. Profiles
Clever needs Profiles [expanded, complete save sets]

Think about it, clever already can:
- save to, read from config files
- saves some [but not all] settings and checkmarks for V/A/S/CH to a save set

Why not expand this functionality and save multiple sets and call them profiles.
you can give these profiles numbers or names. And all of them can be saved in
the config file or in another file.. say profiles.cfg

To start, every existing checkmark and toggle [on/off] setting can be saved in
a profile. The current settings page can have a drop down of profiles to select a
default one from.

The changes to your code can be incremental, and phased in slowly one feature at
a time. I think it is worth the effort.

As always .. thank you for your efforts and keep up the great work.

At scene changes - I have repeated several tests:
The new changes provide useful results for the F1 and Fast10 examples, as well as for other videos and movies.
Excellent work, ProWo!
Thank you very much!
This feature is now useful!

With the number of chapters created info, you can directly estimate if you need an other scan ot not. Thanks for adding!

The threshold is now set to 0,5 by default, but text is telling 0–0,4 is recommended!?
How about making the chapters “Create file” button green?
And why not using the same red from Add chapter also for Deactivate?
As Video duration is just a general information I still would swap it with Integration with muxing.
How about adding the number of created files to Integration with muxing. Everything at a glance.
And could you display the multiplex success message before asking whether to keep the chapter text or not?


[Attachment 89561 - Click to enlarge]

EDIT:
Problem: when a file has a global title and you mux it while Title is not checked, the global title get cleared from the file/metadata.

Use subtitleedit for this.

Thx for the hints, will be implemented/fixed.

The idea isn't bad, but I'm afraid it would overwhelm many users.
Even now, the multiplexing page is quite complex, for example.
The main task for clever FFmpeg-GUI should be to make ffmpeg simple and easy to use.

btw:
reread post #2928

Audio encoding, Channels (change. split. join). Use periods instead of commas.

At the page itself you use "Extract streams", just like on the other pages. On the Main page button it is "Extract Strames" with a capital S.

Would it be useful to offer a feature that automatically fills in the empty “Title” field with the country name if the "Language" field contains a valid entry for audio and subtitle streams, as in the ISO 639-2 table?
On older devices and players, the abbreviations and country names may appear in the selection.

The selection is combined. It displays the code table and fills in the empty title fields. If the check mark is removed, the table closes and the titles get deleted.

FYI,
Issue: 0-channel AAC Audio stream loads into clever, can multiplex with AVC video stream,
outputs 0 size mp4 file with no errors, warnings, or fail message.


[Attachment 89568 - Click to enlarge]

To duplicate issue:

1- Extract video, audio stream separately as shown:

ffmpeg -i input.mp4 -map 0:v:0 -c copy output.mp4
ffmpeg -i input.mp4 -c copy output.aac

2- Each stream can be loaded in Clever separately, successfully as shown:

3- Try to Mux them, no complaints from Clever:
