Operation description
- In asynchronous mode, the media information can be retrieved only after the Message Service (MNS) callback of submitting a media information job is returned. If you have not retrieved the media information for a long period, the job may have failed.
- You can call this operation to query up to 10 media information analysis jobs at a time.
- By default, returned jobs are sorted in descending order by CreationTime.
QPS limit
You can call this operation up to 100 times per second per account. Requests that exceed this limit are dropped and you will experience service interruptions. We recommend that you take note of this limit when you call this operation. For more information, see QPS limit.
