[Web] Add support for playing Android Motion Photos

[ua741]

Motion photos that are uploaded via ente photos app or imported from web app from any source apart from Google Photos export are not playable on the web/desktop app.

How to identify the Android Motion Photo:
FileType will be image and it will contain mvi key in the publicMetadata and the value of the field should be > 0.

How to extract video of Android Motion photo:
The video is part of the image blob. We can read the video by reading the file Bytes from mvi index to end.

Hi @ua741 , I would like to work on this issue. Can you give some directions about where I can start with? Thanks very much for your help!

Hey @shuoO-24, thanks!

We currently have a decodeLivePhoto function used by different parts of the app to decode a downloaded Apple Live photo zip.

we can extend that itself to include the identification check and decode the motion photo accordingly.

As, for the implementation of identification checks,

mvi is a new key, that was not used earlier on the web, so we will need to add it to FilePulbicMagicMetadataProps.

And the checks for detection are
if file is a live photo-> file.metadata.fileType === FILE_TYPE.LIVE_PHOTO
and for motion photo-> file.pubMagicMetadata.data.mvi >0

Hello, just to be sure, does it means that Motion Photos are still properly uploaded to you servers or once this bug is fixed I will have to upload all Motion Photos again so I can see them on ente desktop ?

Android Motion photos are uploaded properly, we just need to add playback support on Web/Desktop.
