A QNAP-os MARS doksijában ezt írják a Google Photos API-ról:
Google Photos API Limitations
When MARS backs up a media file from your Google account, the backed-up file on your NAS may have a different format or resolution compared to the original stored on your Google account. This is because the Google Photos API optimizes the format or resolution of the media file for more efficient transfer over the Internet. These optimizations, however, do not significantly impact typical users. The original media files on your Google account are not changed in any way.
One or more of the following may occur, as a result of Google Photos API limitations, when backing up videos/photos from Google Photos with MARS:
- Video backups:
- MARS may not be able to access videos immediately after uploading them to Google Photos. The backup job may fail, or some files may be skipped. In these cases, wait for a period of time and try the backup job again.
- Videos higher than 1080p and 30FPS will be backed up in 1080p and 30 FPS.
- Image backups:
- Google Photos may alter the pixel format or metadata when MARS retrieves the images. These alterations may change the final file size of the backup.
- Images with the YUV444 color model will be converted to the YUV420 color model. Images with the YUV422 or RGB24 color models will not be converted.
- Location data, including GPS coordinate information, may be removed from certain images.
Arra tippelek, hogy a takeout is ezt az API-t használja, bár a "may be removerd" érdekes megfogalmazás - gyakorlatilag úgy kell tekinteni, hogy vagy visszakapod azt az adatot, vagy nem (ha igen, akkor azt neked kell visszalapátolni a képbe...)
