Detailed Description

Exported symbols for GPAC NodeJS.

This section documents the JavaScript API used to query the filter session.

Unless explictly stated, errors are handled through exceptions.

All constants from GPAC are exported in the module object (e.g. use gpac.GF_Err ...)

The API is very close to the GPAC python bindings.

Function Documentation

init()

void init	(	unsigned long	mem_track = 0,
		DOMString	profile = null
	)

initialize libgpac - see gf_sys_init

When loading the module, libgpac is innitialized with no memory tracking and the default profile. Use this function only if you need to change these settings. This must be called before any other calls to gpac.

Parameters

mem_track	mem tracker mode
profile	profile name, null for default

Here is the caller graph for this function:

e2s()

DOMString e2s

(

long

err

)

convert error value to string message

Parameters

err	gpac error code (int)

Returns

string

set_logs()

void set_logs	(	DOMString	logs,
		boolean	reset = false
	)

set log tools and levels - see gf_log_set_tools_levels

Note

Make sure you have destroyed all associated gpac resources before calling this !

Parameters

logs
reset	if true, resets all logs to default

sys_clock()

unsigned long sys_clock

(

)

get clock - see gf_sys_clock

Returns

clock in milliseconds

sys_clock_high_res()

unsigned long long sys_clock_high_res

(

)

get high res clock - see gf_sys_clock_high_res

Returns

clock in microseconds

set_args()

void set_args

(

Array

args

)

set libgpac arguments - see gf_sys_set_args

Parameters

args	Array of strings, the first string is ignored (considered to be the executable name)

enable_rmtws()

void enable_rmtws

(

boolean

enable

)

enables websocket monitoring server - see gf_sys_enable_rmtws

define the rmt_on_new_client attribute to set callbacks

Parameters

enable

enable or disable server

on_event()

boolean on_event

(

_FilterEvent

evt

)

GPAC event proc callback, initially set to null

Parameters

evt	the user event being dispatched

Returns

true to cancel the event

Here is the caller graph for this function:

Variable Documentation
