Creates an M3U8 index file for a recording in a specified time period.
Operation description
You must have configured Object Storage Service (OSS) before you call this operation. For more information, see Configure OSS. ApsaraVideo Live allows you to record a live stream in the M3U8 format and store the M3U8 file in OSS. You can edit the TS segments that are included in the stored M3U8 file in real time.
- You can create an index file only after a live stream is ingested. If no live stream is available within the specified time period or the name of the specified live stream 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 TS segment. The default duration of a TS segment is 30 seconds. - ApsaraVideo Live stores the information about TS segments for only three months. You can create M3U8 index files only for the recordings of the last three months. - OSS stores TS segments for a time period that is specified by the storage configuration in OSS. For more information, see Configure lifecycle rules. - ApsaraVideo Live stores the information about M3U8 index files for only six months. You can query only the information about the M3U8 index files that are created in the last six months. - OSS stores M3U8 index files for a time period that is specified by the storage configuration in OSS.
