defineOptions()

GOptions gstreamer::defineOptions

(

)

The returned GOptions object contains:

• gstreamer-specific options such as ebuffer and -gstreamer
• the option definitions contributed by dependent modules currently aggregated here

This function is typically used by applications and examples as the module entry point for command-line configuration.

Returns

Fully populated option definition object for the module.

getGStreamerDefinition()

std::vector< GStreamerDefinition > gstreamer::getGStreamerDefinition

(

const std::shared_ptr< GOptions > &

gopts

)

This function reads the "gstreamer" option node and converts each object entry into a GStreamerDefinition value. Each entry is expected to provide:

• format : plugin format selector
• filename : base output filename
• type : semantic output type, defaulting to "event" when omitted

The returned vector preserves the order found in the option node, which is useful when the caller wants output instantiation or reporting to follow user configuration order.

Parameters

gopts

Parsed options container supplying the "gstreamer" node.

Returns

Vector of configured streamer definitions.
