Adobe Flash Media Live Encoder Set-up

Follow the steps below to set-up your Adobe Flash Media Live Encoder software to stream your event.

NOTE: For a full description of all functions, please refer to the Help menu in the Flash Media Live Encoder.

 

 Step 1 - Download the Flash Encoder

You can download the Flash Media Live Encoder here.

 Step 2 - Hook up a live video source

Once you have installed the software, use a video device to connect your video camera to your computer. Most users use a USB video capture device to connect their video camera to their computer. You can click on one of the example products in the right column and search Amazon for a USB video device.

 

Step 3 - Configure the Flash Encoder

 

  • Preset Options:
    Select the "Medium Bandwidth (300 kbps) - H.264" as a starting point. You can adjust the Video Bit Rate to be higher, but remember that your ability to stream High Bandwidth or multiple bit rates is dependent on your internet connection. You must have a very fast UP connection speed in order to stream higher bit rates than 350 or 400 kbps.

  • Video Options:
    • Device: Use the Device drop-down to select your USB video device or video capture card.
    • Format: H.264 is the recommended format. This format MUST be chosen to allow for mobile connectivity through Apple iOS devices and other HLS compliant smart phones like Android 3.0+.
      • Click the wrench icon for more settings:
      • Profile: Baseline
      • Level: 3.0
      • Keyframe Frequency: 2 seconds
    • Frame Rate: defualt is 30 fps. Lower frame rates will lower the overal quality of the stream. It is recommended that you keep a minimum of 20 as the frame rate.
    • Input Size: 320 x 240 is the default and recommended setting. This is the video dimensions in pixels.
    • Bit Rate: Recommended Video bit rate is 300 kbps or 350 kbps. It is also recommended that you only use the #1 bit rate option. Setting up multiple bit rates can cause issues with DSL connections that have a slower UP speed.
    • Crop: recommended to keep this un-checked. See Help Files for use.
    • Deinterlace: only available on highbandwidth streams. When selected, activates the video deinterlacing filter, which may improve video quality by applying a simple vertical blur.
    • Timecode: recommended to keep this un-checked. See Help Files for use.

  • Audio Options:
    • Device: Use the Device drop-down to select your USB video device or video capture card.
    • Format: Mp3
      • Channels: Stereo is the default.
      • Sample Rate: Recommended to be 44100 Hz. This option changes the options available in the Bit Rate setting.
      • Bit Rate: 96 Kbps recommended. This is a good rate for basic sound. Higher Bit Rates give better sound quality, but require more UP bandwidth.
    • Format: AAC (recommended for iPhone Mobile streaming)
      • Channels: Stereo is the default.
      • Sample Rate: Recommended to be 44100 Hz. This option changes the options available in the Bit Rate setting.
      • Bit Rate: 48 Kbps recommended. This is a good rate for basic sound. Higher Bit Rates give better sound quality, but require more UP bandwidth.
      • The AAC codec is included in Flash Media Live Encoder for the Mac, but must be purchased as a plug-in for Windows. Visit the Adobe Configuration page for more information.

  • Output / Streaming Options:
    • FMS URL: Paste the Primary Stream URL sent to you in your Flash Streaming Set-up email from StratumVideo.com
    • Backup URL: (optional) This can be left blank.
    • Stream: Enter the title of the stream name sent to you in your set-up email.
      If you are encoding multiple-bit rate streams, you can use the %i parameter to reference the multiple bit rate stream names (ie. mystream%i). %i is the index of the bit rate - 1, 2, or 3.
    • Connect Button: After entering the stream name, click the Connect button to activate the stream. The button will change to read "Disconnect" and then activate the "Start" button at the bottom of the encoder. When you are ready, you will need to click the Start button to start the live stream.
    • Auto Adjust: When required by network limitations, Flash Media Live Encoder automatically adjusts the quality of video by either degrading video quality or dropping frames. See Help Files for use.
    • Save to File: When selected, saves the output to a file. Click Browse to specify a different filename and folder. You can use parameters in filenames. For more information, see the Help Files.
  • Click the START button to start your event

 

 

SAVE your Session Profile

You can also make it very easy to start your stream again by saving your new Profile configuration. To do this simply go to the File menu and select the Save Profile option. You will then be asked to name and save your .xml file. Once saved, you can then open this file from the Flash Encoder to launch the encoder and your live configuration. You can then hit the Start Encoding button to begin your live stream.
