Strange bug with mkv containing fonts:
Mux a font into a simple video.
Load it as the new source.
Now extract all streams and open Multiplex. The extracted audio and video streams apper twice in the multiplex table.
If you extract the streams individually or just two, everything is fine.

This is a bug, will be fixed.

When you drop files on the desktop icon, a new instance opens, but the “Select source file” page does not load/display the file(s).
Is this intentional?

This is not integrated at the moment, but I can add it

Using multiple instances of the application can lead to problems, as BT_open.txt or SWF_open.txt, for example, are overwritten.
Wouldn't it make sense to add new content to existing files?

No, because which instance should then use the temporary files? It would also reduce performance.
I therefore advise against opening several instances at the same time.

How about entries that change the path for your editor and virtualdub?

I will extend the settings for virtualdub2, notepad and LUT's folder, even if virtualdub2 is not used at the moment.

Is there a reason why chapters are not listed on the Source file info page - like attachments?

Chapters are displayed (if available) at the end of the video line.

Could you please preselect the chapters at the Extract streams page like all others?

This is a bug, will be fixed.

The preview fuctionality for the Chapers page is missing. Like for Cut, navigateing to the propper position at the video and note the timestamp for your new chapter.

Embedded chapters cannot be displayed or edited individually. To do this, you must first extract them and then add them as external chapters.

Preview for Cut:
Why does the focus remains on the preview window of ffplay all the time? I cannot use task switch either.

Close the ffplay window first.

@ ProWo

Thank you for 3.3.6.04

It is now displayed correctly. But when I try to delete or edit it, it does not affect the result.

I will add a delete possibility for this wrong written titles.

One more thing, the "All" and "None" option does not affect D (Default tab). This is a good thing. Set tab is activated simultaneously with the D tab. I think the D tab should be activated manually depending on the user. Otherwise all apple devices don't see the default tracks and play them at the same time (playing 2 sounds in 2 different languages in a movie at the same time).

I leave the current setting as it is.
Deselect the default entries that bother you.
By the way, it is an apple player error that it plays all default streams at the same time. As far as I know, it is the only player that does this.

[ProWo]

Please put the Source and Target FPS options back under audio encoding, at least under custom. This is a feature I use all the time to finagle my simpler audio files. Helps me to not use Audacity to to fix the simpler issues and syncs.


[Attachment 84649 - Click to enlarge]

The Presets are ok but it is restricting the freedom, it is now much more difficult to do custom manipulation by only allowing the Factor. It was so easy and convenient being able to alter the Source or Target FPS to achieve the new duration time I desired. I don't want use a calculator to work out the needed factor please.

I changed this for a good reason, because the previous function also implies errors.
This starts with your example, in which you change from 29.97 fps to 24.33 fps without considering that the audio stream of a 29.97 video actually comes from a 23.976 fps video and was taken over unchanged.
Your setting would therefore result in an incorrect audio length.
But be that as it may, I will provide a calculator in the custom setting as before.

Let's assume you have three files to join, 1, 2 and 3. you want to put number 3 in the first position.

Can a batch of .mp4 video files be loaded and have all the .aac audio streams be extracted all at once?

atm, no.

In the meanwhile, I found that a DOS batch file command line for-in-do operation with ffmpeg.exe itself can do this task.

By the way, it is an apple player error that it plays all default streams at the same time. As far as I know, it is the only player that does this.

I discovered that the problem is not that all the tracks are in “Default”, the problem is in “Alternate group”. “Alternate group 1” for all audio tracks. The subtitle tracks are all in “Alternate group 2”. or “Alternate group 3”. Apple plays them without any problem. This is what ffmpeg does when Defaults is not selected. Otherwise it sorts Alternate groups as 1,2,3,4 and causes incorrect playback in apple. The problem is caused by ffmpeg and I couldn't find any code to fix it.

Can clever FFmpeg-GUI change those vertical smartphone videos to horizontal, say for a monitor or TV?
E.g., for MPEG-4/.mp4 files, from:
Width 720 x Height 1,280, Display aspect ratio: 0.562 = 9:16
to:
Width 1,280 x Height 720, Display aspect ratio: 16:9 = 1.78

And, if so, can it also change the codec, like from vp09 to AVC/H264?

In other words, change the DAR with re-encoding?
Could it all be done in one operation, or two separate steps?

you can rotate the video, the dimensions will remain the same, but the orientation will change (see the following two pictures)

You don't need to do anything to achieve this.
Just play the video as it is and it will be displayed exactly the same on a widescreen TV.
If you absolutely want to encode the black bars as 16:9 video, then do this with the following settings:

Hi ProWo. I'm back from vacation and ready for my beta (v3.3.6.06) feedback.

> The multiplex table can now handle extracted fonts and the related streams. Good.

> Files dropped to the destop icon now appear as source in a new app insance. Great.

> Thanks to extend the settings for virtualdub2, notepad and LUT's folder.

Chapter page:
>> The preview fuctionality for the Chapers page is missing. Like for Cut, navigateing to the propper position at the video and note the timestamp for your new chapter.
> Embedded chapters cannot be displayed or edited individually. To do this, you must first extract them and then add them as external chapters.

Yes, of course. I have already experimented with it.
What I mean is intended for new chapters. A ffplay window (like the one in Cut) would be helpful to find your preferred video position and corresponding timestamp for your new chapter.

Precisely because the cut parts keep their original chapters, but these get lost while joining as it result in a new video length. So if you want to stay with chapters here you have to create new ones and ffplay would help.

---

Cut page:
>> Why does the focus remains on the preview window of ffplay?
> Close the ffplay window first.

Sure!
So I have done some research and tests and it looks like that the remaining focus are limitations of ffplay!

---

NEW: Cup page, ffplay works well with chapters!
So could you please change the text of the "ffplay player controls" window to:
Page Down: Back 10min or previous chapter
Page Up: Forward 10min or next chapter

---

NEW: Cut page, endtime error message
Could you prevent entering higher end time values ​​than the duration or reset the value back to the duration after the message close?
So far the too high value remains in the field and you have to reopen Cut to get the duration back.
Nobody remembers the duration!

---

NEW: Multiplex Sort button
Streams in muxed files get automatically sorted by type (video, audio, subtitle, rest) during multiplexing.
Could a Sort button (like None/All) placed over the Type column do exactly the same (including new index numbering). Simply for a better overview of all streams "before" muxing.
The button may disappear after the click and appear after any index change in the table.

---

NEW: Multiplex counter "Muxed Streams: #" behaviour
The red background disappears as soon as any two streams are selected. Like two subtitle streams!!!
What about turning the background to green as soon as one video and one audio stream has been selected?
It could stay yellow in between.
Like a traffic light.

Using other softwares, long ago, I found if I only convert the codec from vp09 to AVC, so it will play on the TV, the video is squashed, and doesn't look right. No videos from the phone would play on the TV, unless I did massive changes. The padding your program can do is necessary. And being able to do it as a batch process is very, very, useful.
Thanks.

Yes, I understand. I had a source file with 8 subtitle tracks for testing. It quickly becomes confusing when deciding what to choose while scrolling.
