Problem Description

Notes
Authentication failure occurs when the API is called.
1. Ensure that the parameters are sorted in alphabetical order when generating the signature.
2. Ensure that the timestamp parameter is set to the current time.
3. See the example parameters on the right. Do the calculation according to your own signature steps, and when your result matches the example, it means that the signature calculation steps are correct.
Parameters:
appkey = e38267c0e86411ebb02aed82acb0ed99
accesstoken = f68f2d10ae9e4604b76fb05cf46bccec
timestamp=1646636485
Signature result: BfWuaC9kmaicCggXc693uK%2BsZQ8qe88O4HVQNTdwZuo%3D
﻿
Parameter errors occur when the API is called.
1. Check whether the request body includes the header parameters without which an error occurs, as shown in the example on the right.
2. The parameter types must be filled in strictly according to the API documentation.

﻿
The quantity of avatars found is incorrect, or no avatars are found.
If you have subscribed to Avatar, see the Paginated Query Avatar List API to query.
If you have subscribed to 2D premium avatars, see the Customer Resource Query Anchor API for the query.
Note:
After ordering the hourly broadcast package on the official website, if both Avatar and 2D premium avatars are enabled, you need to see both sets of APIs to query the relevant avatars separately.
﻿
﻿
Does it support generating videos with a transparent background?
Yes, it supports generating videos with a transparent background in WebM format.
﻿
﻿
Why does the WebM video with a transparent background play have a green screen when it is played?
It indicates that the video player used by the customer does not support the WebM format. Try to play the video in Chrome; if it appears with a black background, it means the video itself is fine.
﻿
Avatar position parameters are not effective after adjustment.
1. Check whether the API being called is the Basic version or the Advanced version, as only the Advanced version supports this feature.
2. Check whether the video output format is set to GreenScreenMP4. Position adjustments are not supported for this format.

How to calculate the initial size of the digital human?
The digital human query API returns OriginZoom (original zoom factor) and PoseImage (digital human pose image). The initial size of the digital human is calculated by multiplying OriginZoom by the width and height of PoseImage.
﻿
Action insertion in the text does not work.
You need to reserve a certain amount of text before and after each action. Since each action requires a different amount of reserved text, it is recommended to reserve at least 10 characters before and after each action.
﻿
Does the digital human support adjustments for the speech rate, intonation, and polyphonic characters?
Sure, see the SSML tags section in the API documentation, i.e. Appendix II: SSML Specification.
﻿
The specified external S3 storage did not receive the digital human video upload.
Please check if the S3 permission settings allow external writing, or if the S3 link in the parameters includes authentication information.
﻿
There are no subtitle files.
Subtitle files are only available for text-driven videos; they are not available for audio-driven videos.
﻿
Quota exceeded: The number of audio production submissions exceeds the limit: 1.
By default, only one audio production concurrency is enabled when the permission is granted, meaning only one audio task can be in production at a time. You must wait for the current task to be completed before submitting another. This can be resolved by purchasing additional audio concurrency.
﻿
Quota exceeded: The quantity of video production submissions exceeds the limit: n.
1. For each avatar type, each user is allowed to process up to 5 video production tasks concurrently by default, shared between the main and sub-accounts. These 5 tasks share concurrency resources with all customers, which may result in task queuing.
2. You can purchase additional dedicated concurrency for broadcasts. For example, if you buy 1 additional dedicated concurrency, you can process up to 6 video production tasks simultaneously. This additional concurrency is exclusive to the user who purchased it.
﻿
Solution to the issue:
1.  Users can implement a task queuing policy.
2.  Purchase dedicated concurrency.
