Genvid Studio sample¶
Warning
The Genvid Studio and Composition feature is provided as a preview. The elements presented here will likely change in the future. The current vesrion is only supported in Google Chrome.
The Studio sample exposes the composition feature of the Genvid stack through a web interface. It can be used with either two instances of a game or with the Genvid Ingest sample. For this example, we use two instances of the Tutorial sample composed in different ways.
You can switch the output from one of the tutorial instancess to the other, as well as create a “picture-in-picture” composition. In “picture-in-picture” mode, either of the tutorial samples can be selected as the inputs for the background picture or the PIP window. You can specify transitions between the two, as well as the window position.
Configuration of the cluster¶
Start a local cluster and set up the tutorial. After confirming it’s working, stop the services and do the following:
If you are on a The Cloud Environment, load the images and then the configuration:
py studio.py -c {clustername} upload-images py studio.py -c {clustername} loadIf you are in a Local Environment, you only need to load the configuration:
py studio.py load
You can now go back in Cluster UI and see that a new job and a link, both named
studio
, were added to jobs
page. You can now start streaming by pressing
the Start All button.
Once the Studio
link turns blue, you can click on it to access the Studio
page.
The Studio website¶
Warning
This version of the Studio website only works on Google Chrome. It is only available as a preview and the interface will likely change in the future.
Monitor¶
The top of the Composition page is the monitor screen. It displays four different areas:
- The top left (preview) is the current Composition settings view.
- The top right (program) is the current broadcast output.
- The bottom left is the first input.
- The bottom right is the second input.
We only started one tutorial instance, so there is only one input active.
Example - How to switch video source¶
Click the green arrow next to “tutorial” on the Cluster-UI jobs page to start a second tutorial instance.
We now have two active inputs.
Select Source 1
as the active input in the Source of the Video Mixer.
Source 1 shows in the preview area, while Source 0 still broadcasts.
Click Cut
in the Transition section of Compose to switch the streaming to Source 1.
Source 1 is now broadcasting.
Example - How to activate picture-in-picture¶
Select Picture-in-Picture
in the Layout dropdown list of the Video Mixer.
Source 0 now shows in the PIP window, while Source 1 is the background image.
Click Cut
in the Transition section of Compose to switch the streaming to
the PIP composition.
The PIP composition is now broadcasting.
You can now experiment with the other settings.
