OcaMediaRecorderPlayer#

This document describes the device side implementation of OcaMediaRecorderPlayer. This class is documented in the AES70 standard as:

Media volume recorder/player that shall provide streaming data access into and out of OcaDataset objects whose Datasets are media files.

Overview#

Class Declaration#

The device side implementation has the following signature.

namespace aes70::device
{
  template <class Implementation>
  class OcaMediaRecorderPlayer : public OcaDatasetWorker<Implementation>
  {

  };
}

The template argument Implementation may implement the following methods.

Note

The signatures given here are just one possibility and that most methods are optional. Implement only those methods which make sense in the context of your device. See the documentation in Implementing AES70 Classes for more details.
