1xxx error codes are returned because errors occur when you call the transcoding API. For more information, see Common errors.
2xxx error codes indicate configuration errors or task parameter errors that are detected after tasks are created. You need to check whether the parameters specified for tasks and parameters of transcoding presets are correctly configured. The following table describes the 2xxx error codes.
|2001||The error code returned because an unknown error occurs.||Contact the technical support.|
|2003||The error code returned because of invalid task parameters, such as invalid parameter types in the preset.||Check the transcoding parameters.|
|2005||The error code returned because the task is canceled by the user or the source terminal. This error often occurs in live recording tasks, where submitting a recording task identical to a previous one will cancel the previous task.||Check whether the task has been terminated or is identical with an existing live recording task.|
|2032||The error code returned because the watermark file specified in the watermarking task does not exist.||Check whether the watermark file exists in Kingsoft Cloud Standard Storage Service (KS3).|
|2033||The error code returned because KMCT is not authorized to access the KS3 bucket or the output file name is not specified for the task.||Check whether KMCT is authorized to access the KS3 bucket in the KS3 console, and check whether the DstObjectKey parameter is specified for the task.|
|2049||The error code returned because conversion from a smaller resolution or bitrate to a higher resolution or bitrate is disabled.||Check whether the task involves this type of conversion. You can enable smart transcoding to avoid this error.|
|2058||The error code returned because a video or audio parameter is missing from the source video.||Use ffprobe to check the original video.|
|2062||The error code returned because the source video is longer than 50 hours. This is a common error in live recording tasks.||Check the source video, slice the source video if it is longer than 50 hours, and try again.|
3xxx error codes indicate errors that occur in the transcoding process. The following table describes the 3xxx error codes.
|3150||The error code returned because the source file is not a video file or is damaged.||Use ffprobe to check the source file or use VLC to play it.|
|316x||The error code returned because an error occurs when KMCT reads the source file in KS3.||Use ffprobe to check the source file.|
|3101||The error code returned because a mirror source is configured for the KS3 bucket. The source file is stored in the mirror, but not in KS3.||KMCT supports only source files stored in KS3.|
