Step 2: Set up the Input

  1. On the Create channel navigation pane, choose Channel and input details.

  2. In the Attach input section, in Input, select an existing input. More information appears.

    • For an RTP push input, the Input destinations section appears. It shows the two locations on AWS Elemental MediaLive that the upstream system will push the source to, when the channel is running. These locations were automatically generated when you created the input.

      For example, rtp://198.51.100.0:5000 and rtp://198.51.100.44:5000.

    • For an RTMP push input, the Input destinations section appears. It shows the two locations on AWS Elemental MediaLive that the upstream system will push the source to, when the channel is running. These locations were automatically generated when you create the input. Each location consists of an address portion that was automatically generated, appended by a folder you specified when you creates the input.

      For example, rtmp://198.51.100.0:1935/movies/classic and rtmp://198.51.100.45:1935/movies/classic.

    • For a pull RTMP input, the Input sources section appears. It shows the locations of the source video; you specified these locations when you created the input. For example, rtmp://203.0.113.0:1935/movies/classic and rtmp://203.0.113.254:1935/movies/classic.

    • For an HLS pull input, the Input sources section appears. It shows the locations of the source video; you specified these locations when you created the input.

      For example, https://203.0.113.0/newschannel/anytownusa.m3u8 and https://203.0.113.254/newschannel/anytownusa.m3u8 (for an HTTPS pull).

      Or mediastoressl://eri39n.data.mediastore.us-west-2.amazonaws.com/premium/canada/mlaw.m3u8 and mediastoressl://eri39n.data.mediastore.us-west-2.amazonaws.com/redundant/premium/canada/mlaw.m3u8 (for an AWS Elemental MediaStore pull).

  3. Complete the Input settings section as described below.

  4. When ready, go to the next step.

Input Settings - Network Input Settings

Complete this section only if the input is HLS. Complete each field as appropriate. For details on a field, select the field and view the help pane.

Input Settings - Other Settings

The fields that are not within the Network input settings section apply to all inputs. Complete each field as appropriate. For details on a field, select the field and view the help pane.

Input Settings - Video selector

This section contains fields relating to PID selection (used to identify the location of the video you want to extract), and relating to the optional color space feature. Complete each field as appropriate. For details on a field, select the field and view the help pane.

Keep in mind that there is no button to add more video selectors because you can only extract one video asset from the input.

Input Settings - Audio selectors

This section is required if you want to extract audio from the input. You create one or more audio selectors to identify the audio to extract. Typically, you identify different languages from the input, but you could also extract different audio codecs (such as AAC and Dolby).

For each audio you want to extract, select Add audio selector. Complete the fields that appear to identify the location of the audio and to specify optional handling of the audio.

Input Settings - Caption selectors

This section is required if you want to extract captions from the input or to specify an external file as the source of the captions. You create one or more captions selectors to identify the captions to extract. Typically, you identify different languages in each selector, but you could also identify different captions formats.

For each captions you want to extract or include, select Add captions selector. For detailed information on setting up input for captions, see Working with Captions, specifically Step 2: Set up the Input.
