Adding stream groups

A stream group is a collection of prioritized media inputs on a Recorder. Inputs (video, image, audio) are mapped to outputs in the same manner as a patch panel. A stream group contains settings for up to four stream types with each stream type being associated with a configured device input and an encoding setting. Stream groups allow you to manage encoding settings for each stream separately.

The number of streams your Recorder can handle will depend on its capacity. For example, a Recorder must have a minimum capacity of 50 to handle four (4) streams.

 Typically, with room-based Recorders, the available inputs are static so creating a single stream group per room is sufficient. However, mobile Recorders may use multiple stream groups because they are used in so many different environments.

To add a stream group:

1.  Click Recording > Stream Groups > Add New.

2.  Click Add a stream and specify the following:

Input

Select the input type from the drop-down list: Video 1, Video 2, Video 3, and Slide.

Label

•      Enter a descriptive name that will help users easily identify the input.

Slide Encoding (Slide stream only)

•      When adding a slide stream, you will also specify the encoding settings that will be used when capturing slide images.

3.  Click Add stream.

4.  Repeat step 2 and 3 for each stream you want to add.

5.  By default, the first stream you add will appear in the largest window. The stream in the largest window has the highest priority (priority 1). The priority of an input descends as you go clockwise. To change a stream’s priority, click and drag it to where you want it to appear in the layout.

6.  Once you have finished prioritizing the stream types, under the largest window (stream with highest priority), specify the media types (encoding settings) for the streams:

7.  Click a media type, click Add Media Type, and specify the encoding settings for each of the video streams.

8.  Repeat steps 6a and 6b if you are adding a second media type.

9.  Click Add.

 If you have multiple video streams, by default, the audio will be synced to play back from the lowest number video stream. For example, if you choose Video 2 and Video 3, the audio will be synced with Video 2 on playback.  For this reason, we recommend always setting the video stream that you want to schynchronize with your audio to the lowest video input  number.

 Once you add a stream group to a template or presentation, there are additional options available: ability to enable slide generation on a video stream and OCR on slide and video streams. For more information, see Enable OCR and slide generation on templates, schedules and presentations. When adding presentations, you can also update a stream’s encoding settings or add new streams to a stream group dynamically.  For more information, see “Adding a new presentation” in the Mediasite Content Manager Guide.
