Write Video to a Rolling Buffer

To write ingested video to a rolling buffer, follow these steps.

To write video to a rolling buffer

  1. Create a new configuration to send to Media Server with the process action, or open an existing configuration that you want to modify.

  2. In the [Encoding] section, add a new encoding task and a configuration section for the task:

    [Encoding]
    EncodingEngine0=RollingBufferEvidential
    
    [RollingBufferEvidential]
  3. In the new section, set the following parameters:

    Type The type of engine to use. Set this parameter to RollingBuffer.
    Stream The name of the rolling buffer to write video to. You must have created the rolling buffer (see Set Up Rolling Buffers).
  4. Decide whether to store an evidential copy of the video or encode the video so that it is optimized for storage and playback:

    For example:

    [Encoding]
    EncodingEngine0=RollingBufferEvidential
    EncodingEngine1=RollingBufferCompressed
    
    [RollingBufferEvidential]
    Type=RollingBuffer
    Stream=evidential
    EvidentialMode=true
    ImageInput=none
    AudioInput=none
    
    [RollingBufferCompressed]
    Type=RollingBuffer
    Stream=compressed
    AudioProfile=mpeg4audio
    VideoProfile=mpeg4video_h264_sd
  5. Save and close the configuration file. HPE recommends that you save your configuration files in the location specified by the ConfigDirectory parameter.
