Creates an M3U8 index file for a recording in the specified time range.

ApsaraVideo Live allows you to record live streams in the M3U8 format, store the M3U8 files and their media segment files in Object Storage Service (OSS) buckets, and then edit the stored media segment files in real time.

Note
  • You can create an index file only after a live stream is ingested. If no video is streamed in the specified time range or the specified live stream name is invalid, the index file fails to be created.
  • The time range that is specified by the StartTime and EndTime parameters must be the duration of at least one media segment file. The default duration of one media segment file is 30 seconds.
  • ApsaraVideo Live stores the information about media segment files only for three months. You can create M3U8 index files only for the recordings of the previous three months.
  • OSS stores media segment files for a time period that is specified by the storage configuration.
  • ApsaraVideo Live stores the information about M3U8 index files only for six months. You can query only the information about the M3U8 index files that are created in the previous six months.
  • OSS stores M3U8 index files for a time period that is specified by the storage configuration.
