Class Global

io.humble.ferry.RefCounted

io.humble.video.Global

public class Global
extends RefCounted

A collection of static functions that refer to the entire package (like version getters).

Field Summary

Fields

Modifier and Type	Field and Description
static long	DEFAULT_PTS_PER_SECOND The default time units per second that we use for decoded MediaRaw objects. This means that 1 tick of a time stamp is 1 Microsecond.
static TimeUnit	DEFAULT_TIME_UNIT The default unit of time that MediaRaw time stamps are represented in.
static long	NO_PTS A value that means no time stamp is set for a given object. if the Media#getTimeStamp() method of an object returns this value it means the time stamp wasn't set.

Method Summary

Modifier and Type	Method and Description
Global	copyReference() Create a new Global object that is actually referring to the exact same underlying native object.
boolean	equals(Object obj) Compares two values, returning true if the underlying objects in native code are the same object.
static int	getAVCodecVersion() Get the version of the FFMPEG libavcodec library we are compiled against.
static String	getAVCodecVersionStr() Get the version of the FFMPEG libavcodec library we are compiled against.
static int	getAVFormatVersion() Get the version of the FFMPEG libavformat library we are compiled against.
static String	getAVFormatVersionStr() Get the version of the FFMPEG libavformat library we are compiled against.
static Rational	getDefaultTimeBase() The default timebase used by media if not otherwise specified.
static int	getVersionMajor() Get the major version number of this library.
static int	getVersionMinor() Get the minor version number of this library.
static String	getVersionStr() Get a string representation of the version of this library.
int	hashCode() Get a hashable value for this object.
static void	init() Internal Only.
static void	setFFmpegLoggingLevel(int level) Internal Only.

Field Detail

DEFAULT_TIME_UNIT

public static final TimeUnit DEFAULT_TIME_UNIT

The default unit of time that MediaRaw time stamps are represented in.

NO_PTS

public static final long NO_PTS

A value that means no time stamp is set for a given object.
if the Media#getTimeStamp() method of an
object returns this value it means the time stamp wasn't set.

DEFAULT_PTS_PER_SECOND

public static final long DEFAULT_PTS_PER_SECOND

The default time units per second that we use for decoded
MediaRaw objects.

This means that 1 tick of a time stamp is 1 Microsecond.

Method Detail

copyReference

public Global copyReference()

Create a new Global object that is actually referring to the exact same underlying native object.

Overrides:

copyReference in class RefCounted

Returns:

the new Java object.

equals

public boolean equals(Object obj)

Compares two values, returning true if the underlying objects in native code are the same object. That means you can have two different Java objects, but when you do a comparison, you'll find out they are the EXACT same object.

Overrides:

equals in class Object

Returns:

True if the underlying native object is the same. False otherwise.

hashCode

public int hashCode()

Get a hashable value for this object.

Overrides:

hashCode in class Object

Returns:

the hashable value.

getDefaultTimeBase

public static Rational getDefaultTimeBase()

The default timebase used by media if not otherwise specified.

getVersionMajor

public static int getVersionMajor()

Get the major version number of this library.

Returns:

the major version number of this library or 0 if unknown.

getVersionMinor

public static int getVersionMinor()

Get the minor version number of this library.

Returns:

the minor version number of this library or 0 if unknown.

getVersionStr

public static String getVersionStr()

Get a string representation of the version of this library.

Returns:

the version of this library in string form.

getAVFormatVersion

public static int getAVFormatVersion()

Get the version of the FFMPEG libavformat library we are compiled against.

Returns:

the version.

getAVFormatVersionStr

public static String getAVFormatVersionStr()

Get the version of the FFMPEG libavformat library we are compiled against.

Returns:

the version.

getAVCodecVersion

public static int getAVCodecVersion()

Get the version of the FFMPEG libavcodec library we are compiled against.

Returns:

the version.

getAVCodecVersionStr

public static String getAVCodecVersionStr()

Get the version of the FFMPEG libavcodec library we are compiled against.

Returns:

the version.

init

public static void init()

Internal Only. Do not call.
Methods using the C++ interface that will not necessarily
create other Global object should call this. In general,
unless you're extending Humble Video directly yourself, ordinary
users of this library don't need to call this.

It's main purpose is to ensure any FFmpeg required environment
initialization functions are called, and any Humble Video required
environmental contexts are set up.

setFFmpegLoggingLevel

public static void setFFmpegLoggingLevel(int level)

Internal Only. This method can be used to turn up or
down FFmpeg's logging level.

Parameters:

level - An integer value for level. Lower numbers
mean less logging. A negative number tells FFmpeg to
shut up.
