Detailed Description

A muxer and its methods.

Function Documentation

Initialize a muxer.

A muxer multiplexes the events of its generators in a time-ordered fashion based on their timestamp in nanoseconds from origin.

The generators must be kept available by the caller until it no longer wants to use the muxer.

Parameters

gens	the generators to multiplex
gens_len	the number of generators
evs_cap	the max event array capacity. If zero, ACTF_DEFAULT_EVS_CAP will be used.

Returns: a muxer or NULL with errno set. A returned muxer should be freed with actf_muxer_free().

int actf_muxer_seek_ns_from_origin	(	actf_muxer *	m,
		int64_t	tstamp )

const char * actf_muxer_last_error ( actf_muxer * m )

void actf_muxer_free ( actf_muxer * m )

Free a muxer.

Parameters

m the muxer

struct actf_event_generator actf_muxer_to_generator ( actf_muxer * m )

Create an event generator based on a muxer.

The muxer is owned by the caller and must be kept alive as long as the event generator is in use.

Parameters

m the muxer
