Class VideoStreamSerializer

• Defined in File video_stream_serializer.hpp

Nested Types

• Struct VideoStreamSerializer::ComponentHeader

• Struct VideoStreamSerializer::EntityHeader

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 preceeded 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.
