The Wowza Video™ service can send streams to Periscope. This article describes how to create a live stream that delivers live video to a custom Periscope stream target. Then, you can broadcast the stream over Periscope and, if desired, Twitter.
To learn about other live stream settings you might see in the user interface, see Live Stream Setup page in Wowza Video.
Before you start
Periscope has the following broadcast requirements:
- Accepted codecs are H.264 (video) and AAC (audio).
- The recommended resolution is 960 x 540 (16:9 aspect ratio), and the recommended video bitrate is 800 Kbps.
- The maximum resolution is 1280 x 720, and the maximum video bitrate is 900 Kbps.
- For 360 degree streams, the recommended resolution is 1440 x 720, and the recommended video bitrate is 5000 Kbps.
- Streams should be 30 fps with a keyframe interval (i-frame) every 3 seconds or every 90 frames.
- Audio bitrate should be 64 Kbps to 96 Kbps.
- The recommended audio sampling rate is 44.1 kHz.
1. Configure the broadcast in Periscope
Note: For more information, see the Periscope Help Center article What is Periscope Producer?
In the Periscope mobile app
- In the Periscope app, tap the People icon and then tap the Profile icon.
- Tap Settings, and then and tap Periscope Producer in Advanced Sources.
- Tap Create Additional Source for a normal stream or Create Additional Source  for a 360 degree stream.
- Make note of the Source Connection Info (the Server URL and the Stream Name / Stream Key), or keep the Advanced Sources page open and available. You're going to need the Source Connection Info in Wowza Video.
In the Periscope web application
- Navigate to Periscope.
- Click the account profile icon, and select Producer.
- Click Create New Source, and select Normal Source for a normal stream or 360 Source for a 360 degree stream.
- If you have a need to distinguish streams in Periscope, enter a Source Display Name.
- Make note of the Source Connection Info (the Server URL and the Stream Name / Stream Key), or keep the Producer page open and available. You're going to need the Source Connection Info in Wowza Video.
2. Create a live stream for Periscope
Note: If you are simultaneously broadcasting (simulcasting) your stream to Periscope/Twitter as well as another destination such as a Wowza Video hosted webpage; a custom target; or a Wowza CDN edge resource, you can add a custom output rendition for Periscope to an already existing live stream.
Start by adding a live stream whose highest bitrate output rendition is 960 x 540 pixels, Periscope's preferred resolution. Wowza Video doesn't typically generate a 960 x 540 output rendition, so you'll need to create an adaptive bitrate live stream with a custom resolution.
- In Wowza Video, click Add Live Stream.
- On the Live Stream Setup page, enter a Live Stream Name, choose a Broadcast Location, and then click Next.
- If you have the option on the Video Source and Transcoder tab, specify the Live Stream Type as Adaptive bitrate.
Note: This depends on the type of camera or encoder you are using.
- For Closed Captions, choose None.
- For Aspect Ratio, enter the custom value 960 x 540.
- Specify other video source settings, including the encoder, and then click Next.
- Click Next two times to skip the Playback Settings and Hosted Page Settings pages. These options don't matter if you're delivering the stream to Periscope.
On the Review page, click Finish to create the live stream.
Wowza Video creates the live stream and displays the Overview tab of the live stream detail page.
3. Clean up the live stream's transcoder
The live stream isn't quite ready for Periscope. You need to first make some changes to the live stream's transcoder.
- Under Advanced on the left navigation bar, click Transcoders, and then select your live stream's transcoder. It appears as [Live stream name] / Transcoder.
- Click the Outputs & Targets tab.
The Outputs & Targets tab displays the output renditions that Wowza Video created for the live stream, starting with the highest bitrate rendition, the 960 x 540 rendition.
- You won't use the other renditions, so delete them. Starting with the second output on the page, click the trash can icon. When prompted, click OK to confirm that you want to delete the output.
- Repeat step 3 to delete the other adaptive bitrate output renditions until only the highest bitrate rendition remains.
Next, edit the 960 x 540 output rendition to conform to Periscope's requirements.
- Click the pencil icon for the 960 x 540 output rendition and make the following changes:
- Set the Video Bitrate to 800 Kbps and the Audio Bitrate to 96 Kbps.
- Select Main for the H.264 Profile.
There's one more clean-up step. You're not using the stream target that Wowza Video automatically created for the 960 x 540 output rendition, so remove it from the rendition.
- Click the Actions button for the target and then click Remove Stream Target. When prompted, click OK to confirm that you want to remove the target from the output rendition.
Note: If you also want to delete the target from Wowza Video, click the Advanced menu and then click Stream Targets. Select the target, which appears as [Live stream name] / Stream Target. Then, click Delete Stream Target.
4. Add a custom stream target for Periscope
Now, create a custom stream target that sends the live stream to Periscope.
- On the Outputs & Targets tab of the live stream's transcoder page, click Add a Stream Target and then choose Custom.
- On the Create a custom stream target page, enter a Target Name to identify the target in Wowza Video.
- For Provider, choose RTMP.
- For Primary URL, enter the Server URL from the Source Connection Info in Periscope.
- Leave Backup URL empty or enter the Server URL from the Source Connection Info in Periscope.
- For Stream Name, enter the name of the stream from the Source Connection Info in Periscope.
- Leave Target Username and Target Password blank.
- Click Add.
5. Test your setup
When your live stream and stream target are complete, configure your source encoder or camera and test the entire setup.
- Select your transcoder.
- Click Start Transcoder at the top of the live stream's transcoder detail page.
- Click Start to confirm that you want to start the transcoder.
Wowza Video starts the transcoder and connects with the source.
- Start your video source.
- In the Wowza Video web manager, confirm that the live stream is playing by looking at the Video Preview in the Overview tab of the Transcoder Details page.
The video preview displays a frame from the live stream every 5 seconds. The started date and time appear under the preview. Source stream, transcoder, and delivery metrics begin to update.
- On the Advanced Sources page in the Periscope app, check the Preview Broadcast.
- When you're ready to go live, tap Start Broadcast to notify your followers and start the stream on Periscope and Twitter.
- When you're ready to stop streaming, first stop the broadcast in Periscope, then click Stop Transcoder at the top of the transcoder detail page in the Wowza Video user interface, and finally stop the video source.
