Module testing 

In-memory helpers for exercising the engine in downstream tests.

None of this is required at runtime; it exists so consumers can verify their MediaSource/MediaSink/Observer implementations against a real engine without standing up a socket.

Structs

CollectingSink

A MediaSink that records every frame it receives. Useful for asserting what a pipeline produced.

CountingObserver

An Observer that counts the events it sees. Cheap to clone (shared counters) so a copy can be handed to the engine and another kept for asserts.

InMemoryStorage

An in-memory StorageBackend for testing packagers and recorders without touching the filesystem. Cheap to clone (shared object map).

NullSink

A MediaSink that discards everything — the /dev/null of sinks.

Functions

audio_frame

Build an audio MediaFrame at pts (ms).

video_frame

Build a video MediaFrame at pts (ms), keyframe or delta. A terse fixture for tests and examples.
