创建录制视频索引文件

功能介绍

录制索引就是使用视频流HLS格式的录制的ts文件,根据指定的时间范围,剪辑生成新的M3U8文件。

接口约束

录制配置中,录制格式必须有HLS,且参数“record_ts_prefix”必须为默认值:{file_start_time_unix}_{file_end_time_unix}_{ts_sequence_number}。请求时间段内必须有推送成功的直播流。同一个请求所涉及的录制文件必须在相同的OBS桶中。只允许创建开始时间晚于当前时间前30天的录制索引。如果请求时间段的时长小于HLS录制配置中的ts切片时长,将会返回与请求时间段有时间交集的ts分片,不会对ts文件做裁剪。请求时刻和请求中的开始时间间隔小于一个ts分片时长,可能会因为ts分片未录制完成而请求失败。

}

状态码: 400

创建录制视频索引操作失败,常见错误:

  • illegal time range:请求时间范围有误,请查看start_time,end_time参数限制;

  • no record info found:请求时间段内没有录制任务,可能是时间段内没有成功推送的直播流或命令录制规则下未启动命令录制;

  • no ts info found:请求时间段内没有ts文件,可能是请求时间段推流有断流或请求时ts切片文件还没录制结束。

{
  "error_code" : "LIVE.100011001",
  "error_msg" : "参数校验失败"
}
