InputConfig
| Field | Type | Description | Example |
|---|---|---|---|
| Index | Integer | The index. | 1 |
| LayoutId | Integer | The layout ID, which must start from 1. | 1 |
| StreamName | String | The display name of the stream to monitor. | monitorStream**** |
| InputUrl | String | The URL of the input stream. | demo.aliyundoc.com |
| LayoutConfig | LayoutConfig | The layout information. | See the following LayoutConfig table. |
| PlayConfig | PlayConfig | The playback configurations. | See the following PlayConfig table. |
LayoutConfig
| Field | Type | Description | Example |
|---|---|---|---|
| FillMode | String | The fill type. Set this value to none. | none |
| PositionRefer | String | The reference position of the element. Valid values: topLeft, topRight, bottomLeft, and bottomRight. | TopLeft |
| PositionNormalized | Float | The normalized value of the position of the layer, in the format of [x,y].The values of x and y range from 0 to 1.For example, [0.1,0.1] indicates that the layer is horizontally offset by 10% and vertically offset by 10% towards the upper-left corner. | [0.1, 0.1] |
| SizeNormalized | Float | The normalized value of the size of the layer, in the format of [w,h].The values of w and h range from 0 to 1.For example, [0.2,0.3] indicates that the width of the layer is 20% of the screen width and the height of the layer is 30% of the screen height. | [0.2, 0.3] |
PlayConfig
| Field | Type | Description | Example |
|---|---|---|---|
| VolumeRate | Float | The volume. Valid values: 0 to 1. The value is rounded to two decimal places. | 0.50 |
MonitorConfig
| Field | Type | Description | Example |
|---|---|---|---|
| fpsLowThres | Float | The video frame rate alert threshold. This threshold is a scale factor. Valid values: (0.0,1.0]. Default value: 0.7. When the video frame rate of the monitored stream is less than the threshold times the original frame rate of the stream, an alert is triggered. | 0.7 |
| brHighThres | Float | The audio/video bitrate alert threshold. This threshold is a scale factor. Valid values: (0.0,100]. Default value: 1.0. When the audio/video bitrate of the monitored stream is greater than the threshold times the original bitrate of the stream, an alert is triggered. | 1.0 |
| eofDurationThresSec | Float | The interruption duration alert threshold. If the monitored stream is interrupted for a period of time that is longer than the threshold, an alert is triggered. Valid values: (0,65535]. Default value: 0. Unit: seconds. - After the stream is interrupted, the connection is still available and a packet timeout occurs after 5 seconds. The system determines whether there is an interruption based on the timeout. If you set this parameter to a value that is less than or equal to 5 seconds, the threshold is fixed at 5 seconds. If you set this parameter to a value that is greater than 5 seconds, the threshold is the specified value. - If the stream is resumed within the threshold after it is interrupted, no alert is triggered. If you modify the URL of the monitored stream within the threshold after the stream is interrupted, interruption detection is not performed for the stream and no alert is triggered. | 10 |
