Class VideoStreamSerializer

Base Type

  • private gxf::EntitySerializer

class VideoStreamSerializer : private gxf::EntitySerializer

Data marshalling codelet for video stream entities.

Serializes and deserializes entities with the provided component serializers. Little-endian is used over big-endian for better performance on x86 and arm platforms. Entities are serialized in the following format:

| Entity Header || Component Header | Component Name | Component | … | … | … |

Components will be serialized in the order they are added to the entity. Components without serializers will be skipped. Each component will be preceded by a component header and the name of the component. The component itself will be serialized with a component serializer. An entity header will be added at the beginning.
