Object Storage Service:0044-00000014

Problem description

The FragDuration field in the Target node of the PutLiveChannel request is invalid.

Causes

An invalid value is specified for the FragDuration field in the Target node in the XML body of the PutLiveChannel request. The FragDuration field specifies the duration of each transport stream (TS) file in seconds and takes an integer within the [1, 100] range as the value. When you set the value of Type to HLS and the duration of the audio and video data written to the current TS file exceeds the duration specified by FragDuration, Object Storage Service (OSS) switches to the next TS file to write data before the next key frame is received.

Examples

For example, you initiate the following request:

PUT /test-channel?live HTTP/1.1
Date: Wed, 24 Aug 2016 11:11:28 GMT
Content-Length: xxx
Host: test-bucket.oss-cn-hangzhou.aliyuncs.com
Authorization: OSS qn6q**************:77Dv****************
<?xml version="1.0" encoding="utf-8"?>
<LiveChannelConfiguration>
    <Description />
    <Status>enabled</Status>
    <Target>
        <Type>HLS</Type>
        <FragDuration>abc</FragDuration>
        <FragCount>3</FragCount>
    </Target>
    <Snapshot>
        <RoleName>role_for_snapshot</RoleName>
        <DestBucket>bucketdest</DestBucket>
        <NotifyTopic>notifyTopic</NotifyTopic>
        <Interval>1</Interval>
     </Snapshot>
</LiveChannelConfiguration

The error is returned for the preceding request because abc is not a valid value of the FragDuration field.

Solutions

Make sure that the fields in the Target node are valid. The following code provides a valid sample request:

PUT /test-channel?live HTTP/1.1
Date: Wed, 24 Aug 2016 11:11:28 GMT
Content-Length: xxx
Host: test-bucket.oss-cn-hangzhou.aliyuncs.com
Authorization: OSS qn6q**************:77Dv****************
<?xml version="1.0" encoding="utf-8"?>
<LiveChannelConfiguration>
    <Description />
    <Status>enabled</Status>
    <Target>
        <Type>HLS</Type>
        <FragDuration>2</FragDuration>
        <FragCount>3</FragCount>
    </Target>
    <Snapshot>
        <RoleName>role_for_snapshot</RoleName>
