VIDEO.MOV & PHOTO.3GP

IronTom

My Linux MINT has more than 3 applications that will play .MOV files.
I use VLC for real "movies", and MELT for smaller eMail attached files.
Downloaded .MOV files are no problem.
MINT_Settings_Manager shows two MIME types for that suffix. Double-Click a .MOV file and it will allow you to choose which opener.

Browser-based mail apps (both Google & Vivaldi) are confused with attachments.

All attachments must be handled using the MIME assignments per the operating system.
Other "enhancements", smart phones, clouds, alien planets, etc. are secondary to this issue.
We scientists use many non-standard suffixes, with an array of proprietary software, that our messaging systems must accomodate. This .MOV issue is just the tip of the iceberg.

That all said, where/how do I make these assignments ?
Or, do we stay with Thunderbird, Outlook, and other non-browser message systems ?

ALSO:
3GP common iPhone photo is not handled.

Mime types is a working in progress, can you provide one or two examples?

IronTom

??? .MOV and .3GP

Programmers 'working-in-progress' will have many, many examples.

I review offsite-testing-reports from iPhones, tablets, laptops, etc..
Webmail shows the text and provides a Download function for the attachments, which I target to my desktop.
I keep a Vivaldi browser TAB open showing file:///home/my/Desktop/ to view the file after it arrives. Note: Webmail-Download does NOT show the download progress.

Currently utilizing Google Voice for receiving/translating voice into Gmail. Phone text messages are also converted to Gmail. I hope to link Webmail to IMAP/Gmail.

@IronTom Playback of MOV (QuickTime) files is not supported by most browsers without a plugin:
https://developer.mozilla.org/en-US/docs/Web/Media/Formats/Containers#QuickTime

However, it is possible to "trick" the browser to play back such a file by giving a type of video/mp4 instead of video/quicktime. This will pass the video along to FFMpeg to be decoded (source).

3GP files should be playable, also from the local file system.

Here's a sample test file:

Using the Vivaldi browser & techslides .com/demos.... I can click & play 4 of the 5 demos. However, the FLV file auto-magically downloads to my desktop, where it will play with FFMpeg, VLC or MELT.

Using the Vivaldi Webmail... that is, someone else, using their smart-phone, attaches the 5 demos to a email-message and sends it to my eMail address.
That is more like my Webmail & Gmail problems (both being browser-based).

B.T.W. I don't know how to change the name of a emailed-attachment, unless Its downloaded.

@IronTom I don't really understand what your issue is?

Both FLV and MOV files will be downloaded by Vivaldi since it doesn't know what to do with these formats, and this is the issue with other browsers as well. These files can't be played in a browser without special players: For FLV this is usually custom Javascript players, for MOV this is the Quicktime plugin, which simply won't work in modern browsers because none support NPAPI.

Vivaldi Webmail will simply offer you a download of all attachments, there is no internal viewer for any video file type.

You can check what MIME type is assigned by the file command on your OS:

$ file --mime-type small*
small.3gp:  application/octet-stream
small.flv:  video/x-flv
small.mp4:  video/mp4
small.ogv:  video/ogg
small.webm: video/webm

Webmail...no internal viewers... That is the answer, I was avoiding.
Please, Re-Read my original posting

Since I must communicate with Android & Apple phones, I must continue to use a non-browser-based program like Thunderbird.

Thanks for you input.
