Function Documentation

defineOptions()

GOptions gstreamer::defineOptions

(

)

The returned GOptions aggregates:

• gstreamer options (buffer settings and output definitions)
• options from dependent modules (e.g. gdynamicdigitization)

Returns

A fully populated GOptions instance for this module.

getGStreamerDefinition()

std::vector< GStreamerDefinition > gstreamer::getGStreamerDefinition

(

const std::shared_ptr< GOptions > &

gopts

)

This reads the "gstreamer" option node and creates a list of GStreamerDefinition objects. Each entry is expected to contain:

• format : plugin format token.
• filename : base output filename (without extension).
• type : output type token (defaults to "event" when omitted).

Parameters

gopts

Options container.

Returns

Vector of configured output definitions.

gstreamersMapPtr()

std::shared_ptr< const gstreamersMap > gstreamer::gstreamersMapPtr ( const std::shared_ptr< GOptions > & gopts, int thread_id )

inline

This helper is intended to run inside a worker thread. It:

• Parses the configured gstreamer outputs from options.
• Specializes each output definition with thread_id (appends "_t<id>" to the base filename).
• Dynamically loads the corresponding plugin and registers the object.
• Stores each streamer in the returned map and configures it with define_gstreamer().

Note:

• The returned map is owned by the caller via a shared pointer.
• Opening connections is intentionally left to the caller (to keep API flexibility).

Parameters

gopts	Options container.
thread_id	Worker thread id used to specialize output names.

Returns

Shared pointer to a map from plugin name to streamer instance.
