If you have an encoder that is not directly integrated into Microsoft Stream, learn how to setup and configure the encoder manually for Live streaming with Microsoft Stream.

Microsoft Stream accepts live feeds from a variety of different encoders that output RTMP or RTMPS. Each encoder is different, so make sure to follow the guidelines for the encoder configurations when sending to Stream. Check out the list of tested encoders with easy setup to get started.

• When starting a broadcast, the API response will include an RTMP stream URL which can be used for non-encrypted streaming to our servers. Note that if you are using RTMP and using a persistent stream key generated with the Live Video Composer, you should reset your persistent key and update any devices that use them or your streams will fail.

However, when comparing YouTube Live vs Facebook Live it’s important to consider any drawbacks. In our own research and trials, we discovered some major downsides to.
• Stream to the Secure Stream URL. Pass the securestreamurl value that you captured in the last step to your encoding device and stream live video data to it. Once the LiveVideo object detects streaming data, the broadcast will go live on your User profile. View your profile and verify that a new live video post has been created and is broadcasting your streaming data.

To learn how to setup a Live event in Microsoft Stream, read about creating live events. If you are already using an encoder that is integrated with Microsoft Stream, read about configuring encoders for live streaming.

Configure manually

But if there is already facebook app on mobile and then the user installs my app, the user is never logged in. From what I know, I think this might be a problem of single sign on, and I think this is somewhat related with generating proper application hash key, and using the hash key in facebook application which I used to log into the mobile app.

For that, you’ll be going to need Facebook API key and for those who don’t have their Facebook API key yet, then today is your lucky day because you’ll be going to learn how to acquire it. Below is a short guide on how to acquire your own Facebook API key: 1. Log in to Facebook. Next, ADD Facebook Developer application.

After you save the live event (read Creating live events for details), you can see the list of integrated encoders in the Select encoder drop down list on the Encoder setup tab. The ingest URLs are also generated at this time. Select Configure manually to setup an encoder not in the list of integrated encoders.

Setup

1. Select Start setup to create an ingest channel for live streaming. Wait for the setup to be complete. You will see a Ready to connect message on the screen.

2. Copy and paste the following settings into the encoder of your choice:

   a. Server ingest URL: In your encoder, this may be called URL or Address. Microsoft Stream does not require a stream key or name, so you can fill this in with any non-empty value such as MicrosoftStream.

   b. Secondary server ingest URL: If supported by your encoder, use this URL to double push to improve durability and resiliency. Since this is outputting a redundant stream from your encoder, it will require double bandwidth. So, make sure that you have the required bandwidth capacity to support this. This is listed under the advanced section.

   c. Use the Secure Connection (SSL) toggle to switch between RMTP or RTMPS protocols for the ingest URLs. Note that your encoder must support RTMPS to use it.

3. Make sure your encoder is configured with the correct settings as per our recommended encoder settings below.

4. Configure your encoder with the desired audio and video sources.

5. Start streaming from your encoder to the Microsoft Stream ingest endpoints. Free microsoft 2010 product key generator.

6. Go back to Microsoft Stream. After you are able to see the preview from the encoder, select Start event to go live so your audience can see the live event.

Recommended encoder settings

Ingest protocols

• Single bitrate RTMPS or RTMP

Video format

• Codec: H.264
• Profile: High (Level 4.0)
• Bitrate: Up to 5Mbps (5000 kbps)
• Strict Constant Bitrate (CBR)
• Keyframe/GOP: 2 seconds
  • There must be an IDR frame at the beginning of each GOP
  • Frame Rate: 29.97 or 30fps
  • Resolution: 1280 x 720 (720P)
  • Interlace Mode: Progressive
• Pixel Aspect Ratio (PAR): Square

Audio format

• Codec: AAC (LC)
• Bitrate: 192 kbps
• Sample Rate: 48 kHz or 44.1 kHz (recommend 48 kHz)

Playback requirements

• Both an audio and video stream must be present in order to playback content in Microsoft Stream.

Configuration tips

Stream Key Facebook

• Whenever possible, use a hardwired internet connection.

• A good rule of thumb when determining bandwidth requirements is to double the streaming bitrates. While this is not a mandatory requirement, it will help mitigate the impact of network congestion.

• When using software based encoders, close any unnecessary programs.

• Don't change your encoder configuration after it has started pushing. It has negative effects on the event and can cause the event to be unstable. If you want to do this before the event has started, you must disconnect using the producer controls in Microsoft Stream and start setup again.

• If the encoder is disconnected during the live event, reconnect it keeping the same timestamps of continuing process. Note that any discontinuity may cause audio or video issues on certain browsers and devices.

• Give yourself ample time to setup your event. For high scale events, its recommended to start the setup an hour before your event.
