Overview ¶
Package cast turns a resolved media stream into playback on a renderer.
It is device-agnostic and carries no device-type switch. Play resolves the source (renderer-independent) and hands core.Connect plus the resolved stream to the pipeline executor, which connects the renderer, computes a pure core.Plan from its advertised capabilities, and runs the stages the plan names. Every device concern lives either in the device adapter (internal/device) or is expressed as capability data the plan reads, so no device family is a distinct code path here.

Functions ¶
func Play ¶ added in v1.0.0
Play resolves a stream and casts it to the configured device. Source resolution is renderer-independent and happens here; connecting the renderer is left to the pipeline, which times it against the delivery path: a non-self-fetching renderer connects concurrently with the pull, so slow discovery does not age a short-lived signed URL before the first byte. There is deliberately no device-type branch: adding a renderer family is a device adapter plus a set of capability values.
Types ¶
type Config ¶ added in v1.0.0
Config is the application-facing cast configuration. It is just core.Config embedded, so cfg.Device etc. read through and cfg.Config is the exact value the shared machinery wants. The subtitle-transcription knob (Whisper) now lives on core.Config itself, because the pure planner reads it to choose the subtitle axis and must reach it with no import of any renderer; there is no separate Whisper field here to shadow it.
type NetworkConfig ¶ added in v1.0.0
type NetworkConfig = core.NetworkConfig
Every config section's type is re-exported here so the application composes the cast surface through this one package (cast.NetworkConfig, cast.WhisperConfig, ...) instead of reaching into core or the subtitle building block. The definitions live in the packages that consume them. The device section is the exception: the composition root (internal/config) owns its own device config so it can bind a family's connect settings, so no device alias is re-exported here.
type TranscodeConfig ¶ added in v1.0.0
type TranscodeConfig = core.TranscodeConfig
Every config section's type is re-exported here so the application composes the cast surface through this one package (cast.NetworkConfig, cast.WhisperConfig, ...) instead of reaching into core or the subtitle building block. The definitions live in the packages that consume them. The device section is the exception: the composition root (internal/config) owns its own device config so it can bind a family's connect settings, so no device alias is re-exported here.
type WhisperConfig ¶ added in v1.8.0
Every config section's type is re-exported here so the application composes the cast surface through this one package (cast.NetworkConfig, cast.WhisperConfig, ...) instead of reaching into core or the subtitle building block. The definitions live in the packages that consume them. The device section is the exception: the composition root (internal/config) owns its own device config so it can bind a family's connect settings, so no device alias is re-exported here.

Package core holds the device-agnostic decision layer and the machinery every cast shares: config, source resolution, device discovery/connect, the pure Plan (delivery/subtitle/output axes) with its copy-vs-encode resolvers, and the replay-server delivery.
