While we're working on an in-house solution for clip playback we designed a process that will allow you to add video playback or screen capture to your Vidpresso live streams.
This Tutorial is not for the faint of heart. But if you follow this step-by-step process we'll show you how it's done! There's also a video of the steps embedded below.
We'll use an awesome little program called CamTwist to provide an additional input into Vidpresso.
Download CamTwist (get the Beta version, it's pretty stable) (LINK:http://camtwiststudio.com/download/)
Install CamTwist and launch it.
First, we need to set up CamTwist to do what we need. Open the Preferences menu CamTwist>Preferences.
Change the Frame Rate to 30.
Change the Video Size to 1280X720.
Restart your computer, so it will recognize CamTwist as a source.
Open your Video Player. We recommend VLC (Link:http://www.videolan.org/vlc/index.html)
Open a video you want to add to your stream.
For this example we've loaded a show intro into VLC
Step 5: Tell CamTwist what to show in Vidpresso.
In CamTwist click "Desktop+", then the "Select" button. This will allow us to create a video input source from our Video Window.
Step 6: Settings for our Desktop+ source.
Under the "Adjust Settings" tab in CamTwist make sure "Desktop+" is highlighted. Then set these settings in the Settings tab.
Select "Confine to Application Window".
Select the window of the video player we opened in Step 4. Our window shows up as "VLC (CountdownShow...".
Depending on your video player you may want to adjust the auto-selected portion of the window. For example, we don't want the player transport and buttons to appear in our stream, so we'll crop them out.
Click "Select capture area".
Adjust the black handles to crop out any unwanted parts of the window.
Click "Finished selecting" in CamTwist.
We're nearly there!
We need to save this setup in CamTwist.
Under Step 3 in CamTwist, click "Save Setup" and give it a name. i.e., "VLC Video" This way you always have this screen capture setting saved.
Now we need to make sure we can get audio from this video into Vidpresso. We'll need another bit of software for this. Loopback will allow us to re-route audio from an application into the Vidpresso platform.
Download Loopback (Link)
*While Loopback is free to download, the quality of audio passing through loopback is degraded after 20 min.
Setup a New Virtual Device.
Click the + sign on the bottom left next to "New Virtual Device".
At the top of the page, call your device something you'll remember. Like VLC Audio.
Then click the drop-down "+" to select the app that is playing your video. In this case it's VLC. For you, it might be Skype. Select it so it will show up in the list
This new audio device will now be selectable in your system settings.
Now we launch Vidpresso.
In Chrome, go to Live.Vidpresso.com and start a stream. After you set your stream settings. Click the +Camera button in the bottom left.
Change the drop-down for video to show CamTwist.
And your Audio device. The audio Dropdown should be the new device you created in step 8. (Turn Noise reduction Off.)
Now you'll be able to see your video source in Vidpresso.
You will still need to play the video using your player.
It may help to think of CamTwist and Loopback as a patch cable connecting your Video playback source to your distribution platform, Vidpresso.
This is admittedly a technical and complex set up. With this many moving parts, it's may require some trial and error. If you are a current Vidpresso Customer, we're happy to help you get it set up!
