Can you use the same green for the notification in the bottom right corner?

[Attachment 87819 - Click to enlarge]

ADD:
Overall, the colored buttons are certainly helpful.

Add 2:

The color of the individual buttons remains on all pages until the last task has been completed. Great.

[ProWo]

Can you use the same green for the notification in the bottom right corner?

No, because the notification green is the same as the action buttons color.
But i could change the new button color.

[Findu]

I understand. What's more important is that you can read it well.

Two more things for Batch scan for errors:
Shouldn't "Hardware acceleration" be called "Hardware decoding" because "-f null -" check for decoding errors.
Since software decoding isn't a performance difficulty for a long time, you can better assess whether it's still an advantage for you, like at the "Video decoding" page.

When you exit Join, you ask now whether any remaining files should be deleted, like in Multiplex. Why not do the same for batch tasks?

Will rename it to HWA decoding.

Because batch tasks are tasks and not already created files.

BTW
Changed the new button color to purple.
Will upload it tomorrow.

EDIT:
Uploaded.

Quick question: Does clever support opus Freq other than 48k? currently the drop down has only one value [48k].

[Findu]

@ ProWo

Great adding the purple "Streams" button.
The button preselection has also disappeared on the "Select source page" and the "Main page". Thank you.

The text "HWA decoding" could also be used at the "Video encoding" page. Then it is uniform.

[ProWo]

Thx for the hint. Bug.
opus supports 8khz, 12khz, 16khz, 24khz and 48khz.
Will be fixed soon.

Issue: The only resizable column that I came across is Title; but the resize works backwards [!!?].
I think the resize functionality is very usefull, especially for Title & File Name.
Please add resize to both columns, and kindly standardize across all related grids.


[Attachment 87822 - Click to enlarge]

[videoAI]

AAC (Advanced Audio Coding) and AAC-MF (AAC Main Profile) are both audio coding formats, but they have some key differences in terms of their design, use cases, and performance. Here's a comparison:

AAC (Advanced Audio Coding)

Overview:
- AAC is a standardized, lossy compression audio coding format designed to be the successor of the MP3 format.
- It is part of the MPEG-2 and MPEG-4 specifications.

Features:
- Efficiency: AAC generally provides better sound quality than MP3 at the same bit rate.
- Bit Rates: Typically ranges from 32 kbps to 320 kbps.
- Profiles: AAC has several profiles, including Low Complexity (LC), High Efficiency (HE), and Main Profile (MF), among others.
- Use Cases: Widely used in digital radio, streaming services, and mobile devices.

Advantages:
- Better compression efficiency compared to MP3.
- Supports a wide range of bit rates and sampling frequencies.
- Widely supported across various devices and platforms.

Disadvantages:
- May require more computational power for decoding compared to simpler formats like MP3.

AAC-MF (AAC Main Profile)

Overview:
- AAC-MF is a specific profile within the AAC family, designed for applications that require high-quality audio and are not constrained by computational power.

Features:
- Quality: Offers high-quality audio with a focus on maintaining the fidelity of the original sound.
- Complexity: More computationally intensive than other AAC profiles like LC.
- Bit Rates: Typically used at higher bit rates to achieve the best quality.
- Use Cases: Suitable for applications where audio quality is paramount, such as high-fidelity music streaming and professional audio production.

Advantages:
- Provides the highest quality audio within the AAC family.
- Suitable for applications where computational resources are not a constraint.

Disadvantages:
- Higher computational requirements for decoding.
- May not be as widely supported as the LC profile in some devices and platforms.

Summary

- AAC is a versatile and widely supported audio coding format that offers good compression efficiency and sound quality.
- AAC-MF is a specific profile within AAC that focuses on high-quality audio at the cost of higher computational requirements.

Choosing between AAC and AAC-MF depends on the specific needs of your application, including the required audio quality, available computational resources, and the target devices or platforms.

In the grids there should be no resize option for the columns at all. I will fix this.

[videoAI]

Please don't take the resize away .. I wanted it fixed .. not removed.

BTW, is there a reason why you're not using a dynamic grid [with sortable, resizable columns built in] like DataGridView.
it might help us frame our expectations / requests, if you tell us a bit about the programming language you are using.
I'm guessing it is 'winforms' ?

Programming is not a problem, I don't want people playing around with the grids because it doesn't bring any advantage.
The information is all there and visible, that should be enough.

@ProWo

Issue: using MS Soft Keyboard, in Preview, Pressing Space doesn't Pause/Resume, while pressing P works fine. [!!?]
Also the preview audio is very loud. please decrease the audio to ~ 70% of original. [this is a simple ffplay cmd]

And a tiny request ..

I am visually challenged, I can't use my laptop screen or keyboard, instead I use a large monitor, a mouse, and MS on-screen
soft keyboard. The issue is, the soft keyboard can't be minimized, and it is always on top. using clever preview with keyboard
keys is a challenge for me.


[Attachment 87825 - Click to enlarge]

I wish you would consider allowing me, and other users, to use the mouse buttons & wheel .. for example as follows:

Left click -> Pause/Resume
Right click -> Jump between I-frames [already implemented]
Mouse wheel -> single frame step

Thank you .. from all the senior citizens, elderly, and the disabled/disadvantaged out there ..

There are many problems with this request.

1. Mouse right click is already used (to determine the position in FFplay)
2. To reassign the left click and the mouse wheel, the normal mouse status must be changed. This requires a trigger. This could be the start of ffplay.
3. But this is where the biggest problem arises. How to leave the changed status? The mouse cannot be used for this.

As you can see, the matter is complicated and would cause problems, especially for other users.

[videoAI]

Please see my response ..

And a tiny request ..

1. Mouse right click is already used (to determine the position in FFplay)
[right click stays as is - no change here]
2. To reassign the left click and the mouse wheel, the normal mouse status must be changed. This requires a trigger. This could be the start of ffplay.
[no need to use Left click also .. see #3]
3. But this is where the biggest problem arises. How to leave the changed status? The mouse cannot be used for this.
[you can use the wheel middle click instead for #2 (pressing the wheel down achieves this).
Translated with DeepL.com [welcome to the AI age .. ]

so .. it becomes like this ..

Right click -> no change
Left click -> no change
Middle Mouse click / Wheel Click -> Pause/Resume
Mouse wheel -> single frame step

note: The middle mouse click and the mouse wheel click are two distinct actions that can be performed with a mouse, and they serve different purposes depending on the context and the software being used.

@ ProWo

Thanks for the recent changes. They're working as intended.

If you remember, the title column width was made adjustable because the text was sometimes too long, and you could also enter your own text here.
Is there a way to automatically adjust the column width beyond its minimum after entering text?

[Attachment 87826 - Click to enlarge]

ADD:
And could you please change the Chapters warning text so that the > symbol is removed? That would be easier for everyone to understand.

Fixed to fit content.

The symbol means greater than, so it has its justification. I have replaced it with text.

[ProWo]

so .. it becomes like this ..

Right click -> no change
Left click -> no change
Middle Mouse click / Wheel Click -> Pause/Resume
Mouse wheel -> single frame step

No way to achieve that.
The mouse wheel handle only works if the window with this handle is active; however, the active window in the preview is the FFplay window, and no code can be implemented in this.

[videoAI]

@ProWo

How about the 2 pending issues.

Issue #1 using MS Soft Keyboard, in Preview, Pressing Space doesn't Pause/Resume, while pressing P works fine. [!!?]
and
Issue #2 The preview audio is very loud. please decrease the audio to ~ 70% of original. [this is a simple ffplay cmd]

Dropping the request ..

Tested with MS Virtual Keyboard on Windows 11 (Windows key + Ctrl + O):
Space bar and P both work as expected. So there is no issue.

Issue #2 The preview audio is very loud. please decrease the audio to ~ 70% of original. [this is a simple ffplay cmd]

FFplay's default volume is 100%.
If this is too loud for you, reduce the system volume in Systray.

[videoAI]

@ ProWo

Thank you for responding ..

#1 Tested with MS Virtual Keyboard on Windows 11 (Windows key + Ctrl + O):
Space bar and P both work as expected. So there is no issue.
I am still having this issue here, I will consider it "unresolved". No need for further action on your part. Thanks.

#2 FFplay's default volume is 100%.
If this is too loud for you, reduce the system volume in Systray.
Thanks for the advice, I would never have thought of it myself.

As always keep up the good work ..

[Findu]

@ ProWo

The "fit content width" for the Multiplex Title column is working well.
And thanks for changing the chaptes warning text.

Join videos with different resolution and fps:

You have already implemented codecs and streams indexes check for joining, but when I join two files
1) 1356x 680, 23.976 (24000/1001) FPS, 28 min 19 s
2) 1280 x 720, 25.000 FPS, 39 min 5 s

The joined video (1+2) has
Duration : 1 h 7 min (fits)
Frame rate : 46.068 FPS
Offset : 0,023000
VLC plays 1 and show a black screen till 1:07, then playing 2.

When I join 2 and 1, the joined video (2+1) has
Duration : 2 h 6 min
Frame rate : 13.104 FPS
Offset : 0,022969
VLC play 1 in connection 2 and then show a black screen till 2:06.

For two other videos with different resolution and fps, the second video (1+2) is not displayed at all or the second (2+1) is played in slow motion.

Other players also have problems.

Maybe you could add columns for Resolution, Frame Rate, Sample Rate and Channels in the grid, although that is not necessary for a successful merging. This makes it easier to see whether there are differences in the parts.

Which containers did you join?
Do the individual parts have different bit depths?

I have tested mkv, right now:

1) 1920 x 800, 23.976 fps, DAR 2.40, YUV 4:2:0, 8 bits
2) 1280 x 534, 23.976 fps, DAR 2.40, YUV 4:2:0, 8 bits
3) 1280 x 534, 25.000 fps, DAR 2.40, YUV 4:2:0, 8 bits
4) 720 x 300, 23.976 fps, DAR 2.40, YUV 4:2:0, 8 bits
5) 1356 x 680, 23.976 fps, DAR 1.99, YUV 4:2:0, 8 bits

Joined in several sequences.
Played with VLC, Windows Legacy Media Player, no problems, works as expected.

[Findu]

I joined mp4 containers.
All have 8 bits depth.

ADD:
Good hint. Muxing the mp4 parts into mkv before merging works well.

ADD 2:
Using fix framerate, simple remux or normal mux of the mp4 parts into mp4 containers before joining doesn't help either.
