1. Class recording
Only one class recording task can be initiated in a room at a given time.
A maximum of 100 recording tasks can run concurrently in a whiteboard application. To increase the quota, please submit a ticket.
2. Whiteboard push
Only one whiteboard push task can be initiated in a room at a given time.
A maximum of 100 push tasks can run concurrently in a whiteboard application. To increase the quota, please submit a ticket.
3. Whiteboard pages
A maximum of 2,000 pages are allowed in a room. To increase the quota, please submit a ticket.
The rules about calculating whiteboard pages in a room are as follows:
A whiteboard room has one default whiteboard page, which cannot be deleted.
Adding a whiteboard page (
addBoard) will create one page, and deleting a whiteboard page (deleteBoard) will delete one page.For static or dynamic document transcoding (
addTranscodeFile), the number of pages is determined by the input parameter pages. For example, if pages is 10, this file will create 10 whiteboard pages, and deleting the file (deleteFile) will delete 10 pages.Adding a video file (
addVideoFile) will create a whiteboard page, and deleting a file (deleteFile) will delete one page.Adding an HTML5 file (
addH5File) will create a whiteboard page, and deleting a file (deleteFile) will delete one page.For an image group file (
addImagesFile), the number of pages is determined by the input parameter urls. For example, if urls is 10, this file will create 10 whiteboard pages, and deleting the file (deleteFile) will delete 10 pages.4. Class data storage
The class data storage rules are as follows:
Class data is stored for 7 days by default (starting from the last operation time of the class). If no operation is performed on the class within these 7 days, the data will be cleared.
Scenario 1: Class A was last operated on 2022-04-01 12:00:00, and no operation was performed on the class within the following 7 days. In this case, the data of class A was cleared on 2022-04-08 12:00:00.
Scenario 2: Class B was operated on 2022-04-01 12:00:00 and 2022-04-06 13:00:00, and then no operation was performed on the class within the following 7 days. In this case, the data of class B was cleared on 2022-04-13 13:00:00.
Cleared data cannot be recovered.
5. Use limits of common buckets
If bucket configuration is not performed, the resource files generated by document transcoding and whiteboard recording will be stored in the common bucket for interactive whiteboard as follows:
Resource Type | Storage Period |
Video recording file | 3 days |
Document transcoding result | 7 days |
The resource files in the bucket will be automatically deleted after the storage period. We recommend that you perform bucket configuration before using the transcoding or recording feature, to facilitate your own management of the access permissions and lifecycle of resource files.
6. Interactive graffiti
If you use Tencent Cloud Chat as the signaling channel for interactive graffiti, note the following limits:
1. For an application created in the Tencent Interactive Whiteboard console, the default package is the trial edition, which supports a maximum of 20 members in a non-audio-video group, and a maximum of 100 groups per month.
2. For an application imported from Chat, see its use limits here.
3. You can upgrade the application in the Chat console. For detailed directions, see Creating and Upgrading an Application.
