Error Codes

Last updated: 2022-03-01 14:39:51


    The SDK encountered a severe error that makes it impossible for stream publishing to continue, for example, invalid license or API call failure.


    Video encoding failure does not affect publishing. The SDK will handle the issue automatically to ensure successful encoding of subsequent frames.

    Error Code Event Description
    0 V2TXLIVE_OK No error
    -1 V2TXLIVE_ERROR_FAILED A common error not yet classified
    -2 V2TXLIVE_ERROR_INVALID_PARAMETER An invalid parameter was passed in during API calling.
    -3 V2TXLIVE_ERROR_REFUSED The API call was rejected.
    -4 V2TXLIVE_ERROR_NOT_SUPPORTED The API cannot be called.
    -5 V2TXLIVE_ERROR_INVALID_LICENSE Failed to call the API due to invalid license.
    -6 V2TXLIVE_ERROR_REQUEST_TIMEOUT The server request timed out.
    -7 V2TXLIVE_ERROR_SERVER_PROCESS_FAILED The server denied the request.
    -8 V2TXLIVE_ERROR_DISCONNECTED The SDK was disconnected.


    Most warning events trigger protection or recovery logic that involves retries, and in most cases the problems can be fixed by the SDK itself, but some warning events still need to be handled manually. Warnings serve the purpose of reminding you or your end users that an error occurred.
