MP4: improve display of operating system and hardware

[JeromeMartinez]

Improvement of #2179.
Focused on Android and iOS but also handle some cameras, and XML or JSON outputs have separate fields for company name, product name, model, similar to writing app and library.

e.g.

Writing hardware                         : Canon EOS-1D C

Writing operating system                 : Google Android 14
Writing hardware                         : Samsung S23 Ultra (SM-M918B)

Writing operating system                 : Apple iOS 14.7.1
Writing hardware                         : Apple iPhone 12 mini

Here is the output with MediaInfo built from this branch on a video from S23 Ultra that someone sent to me:

Performer                                : Galaxy S23 Ultra
Encoded date                             : 2025-01-12 06:12:18 UTC
Tagged date                              : 2025-01-12 06:12:18 UTC
Writing operating system                 : Google Android 14
Writing hardware                         : Samsung SM-S918B

Performer is still there... and hardware missing 'Galaxy S23 Ultra'... not expected right?

For another model looks fine:

Writing operating system                 : Google Android 13
Writing hardware                         : Samsung SM-M325FV

I created a file based on what I understood as being there, looks like it is not the exact way in the file :(.
Please provide a slice of the file, I need only what is in the "moov" atom, you can find "moov" in the file and cut everything before that before sending it to me ([email protected] if you prefer not to share it publicly), it removes all the A/V content.
Else you need to tweak https://github.com/MediaArea/MediaInfoLib/pull/2189/files#diff-f50cbeb39c0bf1da5a4cc81812b1f9f63ac05b6b2edcea155698c48088fc91deR1046

Galaxy S23 Ultra

Argh, I see, I wrongly wrote "Samsung" instead of "Galaxy" in the file, I change my file and tweak the code.

The thing is, some Samsung phones contain Samsung there and some Galaxy...

I will manage both.

What is the exact string of a file having "Samsung"?
(I wonder if it contains "Galaxy" or not i.e. "Samsung Galaxy S23" rather than "Samsung S23", as it is the marketing name)

MediaTrace of file from Galaxy S23: #2179 (comment)
Sample file from Galaxy M32: #2175 (comment)

I only have files from two types of Samsung phones so don't know if there are other possibilities. Both phones not mine. So far I have not seen other brand Android phones that write this kind of info. Others only have com.android.version which seems to be present for any video created on the phone, not only from camera.

[JeromeMartinez]

So no "S23" with "Samsung", always with "Galaxy".

Even my A41 does not have any info... but still good to show when it is present, and we'll see if we find more...

[JeromeMartinez]

I mean, "Samsung" seems used for the model (technical) name, "Galaxy" for the marketing name, at least up to now.

This PR causes performers such as "Samsung Electronics Nano Philharmonic Orchestra" to not be displayed correctly.

Argh! I need to find a more proper way... Maybe with testing only "Galaxy" there, not "Samsung".
Can you share this file? (only the "moov" atom is useful)

I just tried tagging the previous sample file with Mp3tag. That orchestra name I found on Google. If the Samsung metadata is removed first then it shows performer correctly. Take note that someone might be named Galaxy too 😉

[cjee21]

Sample after tagging with Mp3tag:
samsung_sample (2).zip

At some point I need to have a rule... :(
Storing all the model name is not future proof.
Let's see a proposal...

[cjee21]

For some reason, the performer saved by the phone does not show in Mp3tag or FFmpeg. Only the one added by Mp3tag shows. So there is a difference?

samsung_sample (2).zip

This file has 2 "Performer" fields, one old fashion "auth" atom and another "©ART" in "meta" atom, but I see the idea.
