Inputs & Outputs
- Inputs : 1, Media Format : Raw Video
- Outputs : 1, Media Format: Raw Video
- Output Metadata : None
Properties
Property | Value |
---|---|
trigger_type | When to Collect Metadata - custom_trigger : a custom trigger is fired- auto_trigger :when significant node properties change (auto trigger),- periodic :at an interval (periodic)- scheduled :at fixed times past the hour (scheduled) |
trigger | If set, the metadata is only collected when this trigger condition evaluates to True. The trigger expression must be a valid Dot-notation expression that operates on Pipeline Metadata and evaluates to True or False . See details here.ex. `nodes.annotate_line_counter1.lines.line1.total_objects_crossed_delta > 0 |
interval | How frequently to publish metadata (in seconds). 0 means publish every time it is collected. ex. 60 |
schedule | If set, ignores the Interval property and schedules publishing at a synchronized time. Options: day :Every Dayhour :Every Hour30min :Every 30 minutes past the hour15mins :Every 15 minutes past the hour |
meta_to_publish_type | Type of metadata to publish to google sheets - node_meta : Publish selected metadata from the nodes- object_meta : Publish object attributes and metadata- custom : Define the metadata via a path expression (see below) |
meta_to_publish_regex | Comma separated path expressions to select the metadata that should be published when meta_to_publish_type is custom ex. nodes.*.*_delta, nodes.*.*.*.*_delta |
use_lumeo_gsheets_account | Use Lumeo-managed Google account to publish to Sheets. Easier to setup, but requires you to share your Google sheet with [email protected] ex. True / False |
gsheets_client_email | The email address to use on Google Sheets API requests if use_lumeo_gsheets_account is False.ex. [email protected] |
gsheets_private_key | Google Sheets API Private Key if use_lumeo_gsheets_account is False.ex. -----BEGIN PRIVATE KEY----- (...) |
gsheets_spreadsheet_id | Google Spreadsheet ID ex. 1dTxg-PUPPg4hRJkULek-RgzmVd47RfdH-SGBGuC7iqS |
gsheets_sheet_name | Google Sheet Name ex. Sheet1 |
Google Sheets API registration
To use the Google Sheets API service with your own API account, you need to get OAuth 2.0 credentials from the Google API Console.
Using your Google account, visit the Google API Console website.
Click On Library and search for Google Sheets API
Press Enable button (Fig 1)
You should be redirected to the Google Sheets API Service page.
On the Credentials menu press Create Credentials -> Service account (Fig 2)
On the "Create service account page" you need to introduce the name you want to use for the Service account, the Service account email address, and a short description.
Press Done when finished (Fig 3)
On the next window you can grant the service account access to your project resources (Fig 4)
After the service account is created, you need to open the Keys separator.
Now click on Add Key -> Create new key (Fig 5)
Chose JSON Key type and press Create. (Fig 6)
This should start the download of a JSON file containing your service account credentials.
Open the JSON file with a text editor. (Fig 7)
Here you can find on each line a set of key/value pairs.
The client_email and the private_key are required for the node configuration.
You should use their values (without enclosing quotes) to fill respectively the following fields of the node properties: Google Sheets Client Email and Google Sheets Private Key
On the Google Drive, create a new Spreadsheet. Right-click on the file and press Share
Add the client_email of your service account as Editor. (Fig 8)
To find the Spreadsheet ID, open the spreadsheet file on Google Drive.
You will see an URL like this: https://docs.google.com/spreadsheets/d/10Rx6088O56gDDPpy0FYB9FDZ30Dzj13P-4b5wXwzXTD/edit#gid=0
The 10Rx6088O56gDDPpy0FYB9FDZ30Dzj13P-4b5wXwzXTD part is the spreadsheet ID that should be introduced on the node property Google Spreadsheet ID
To fill the Google Sheet Name node property, check the name on the bottom left corner, in this case Sheet1 (Fig 9)
Metadata to Publish
In this field you can insert multiple path expressions, separated by comma, to include or exclude the metadata that should be published by the node.
Example:
When parsing metadata augmented by the Line Counter Node we can select the total objects that crossed both directions of the lines specified on the Line Counter Node using the following regular expression:
nodes.annotate_line_counter1.lines.*.dir*.*crossed*
Fields appended on-the-fly to metadata published on the Google Sheets
Key | Value |

system_timestamp | Current system timestamp ex. 2021-04-14 09:22:24.617855 |
frame_timestamp | Timestamp computed based on frames difference, since the start of the pipeline execution ex. '0:04:00 |
Metadata
This node does not add any new metadata to the frame.
