Transcoding Broadcaster Templates

Instead of manually selecting input streams to be transcoded, you can define templates with rules for automatic transcoding of input streams according to the settings of a pre-defined Transcoding Template. Every time a new input stream, which matches the conditions of the template, is added, it will be automatically transcoded into the transcoded streams defined in the template's settings. The input streams are identified by system according to naming patterns.

To create a new transcoding template:

1. Click the Inputs tab at the top of the Zixi Broadcaster administrative screen.
2. In the Menu bar, click the Templates ( ) button.
   The Transcoding Templates window is displayed
   
3. Click New to define a new template.
   The following window is displayed:
   
4. In the Input ID pattern field, enter a pattern for the Stream ID of the input stream that will be automatically transcoded. This pattern will be used to identify the input stream and can include variables that are marked with the "$" sign followed by a number (e.g. $1, $2, etc.) and/or with an asterisk "*" wildcard. The patterns should also include a part of the string that requires an exact match. For example, the pattern "$1_stream_$2kbps" will match an input stream "talk_show_stream_600kbps".
5. Click Apply.
   The new template is added to the list of transcoding templates. However, the transcoding will not be active until you define transcoded stream rules.
   
6. Select the newly created template and click the  button, located at the right-hand corner to define a transcoded stream rule.
   The Transcode <template_name> window opens:
   
7. Enter the unique Stream ID. for the transcoded stream.
8. In the Max Outputs field, define the maximal number of outputs that can be connected to the stream.
9. Under Stream Parameters, select the desired Video Profile and/or Audio Profile that you have configured. If you have not configured a video or audio profile you can select Keep original stream. In this case the video or audio input will not be transcoded. You can also set specific transcoding parameters for the specific stream (see table below for more details).
10. Click OK.
    The transcoded input stream rule is created and appears as follows:
    
    

    If an input stream enters Zixi Broadcaster and matches the Input ID pattern, it will be transcoded according to all the transcoded input stream rules that were created.
