Input settings—Video selector
This section lets you identify the video to extract from the input, and lets you enable the optional color space feature.
-
In Video selector, choose Video selector. More fields appear.
-
Complete Selector settings as specified in the table after this procedure.
Keep in mind that there is no button to add more video selectors because you can extract only one video asset from the input.
-
For all input types, complete Color space and Color space usage, but only if you want to configure the handling of color space. For more information, see Handling complex color space conversions.
Determining whether you need to create a video selector
When you planned the channel, you should have identified the video that you need to extract from this input.
You must now determine if you need to create a video selector, to identify the specific asset to extract from the input. Some input types require selectors, some input types don't require them.
The following table specifies whether you need to create a video selector.
| Input type | Add a video selector? | How video is extracted |
|---|---|---|
| CDI | No | MediaLive extracts the first video that it encounters in the source content. |
| Elemental Link | No | The input contains only one video asset. MediaLive extracts that video. |
| HLS | No |
By default, MediaLive extracts the video asset with the highest bandwidth. You can complete the Bandwidth field (in Input settings – Network input settings). MediaLive extracts the highest bandwidth video that is below this limit. |
| MediaConnect | Yes, if the input contains an MPTS | Enter the program or PID to extract. If you don't specify the program or PID, MediaLive extracts the first video it finds. |
|
No, if the input contains an SPTS |
The input contains only one video asset. MediaLive extracts that video. | |
| MP4 | No | The input contains only one video asset. MediaLive extracts that video. |
| RTMP | No | The input contains only one video asset. MediaLive extracts that video. |
| RTP | Yes, if the input contains an MPTS | Enter the program or PID to extract. If you don't specify the program or PID, MediaLive extracts the first video it finds. |
|
No, if the input contains an SPTS |
The input contains only one video asset. MediaLive extracts that video. | |
| SMPTE 2110 |
No |
When you created the input, you identified the video stream to extract. MediaLive automatically selects that video. If the input includes more than one video stream and you didn't enter a media index when you created the input, MediaLive automatically selects the video from the SDP file that has the lowest media index (typically index 0). |
| SRT caller | Yes, if the input contains an MPTS | Enter the program or PID to extract. If you don't specify the program or PID, MediaLive extracts the first video it finds. |
|
No, if the input contains an SPTS |
The input contains only one video asset. MediaLive extracts that video. |
