Detailed Description

NetStream_as ActionScript class.

This class is responsible for handlign external media files. Provides interfaces for playback control.

Member Enumeration Documentation

enum gnash::NetStream_as::PauseMode

Enumerator:

pauseModeToggle
pauseModePause
pauseModeUnPause

Constructor & Destructor Documentation

gnash::NetStream_as::NetStream_as ( as_object * owner )

Contruct a NetStream object.

The default size needed to begin playback (_bufferTime) of media is 100 milliseconds.

gnash::NetStream_as::~NetStream_as ( )

References gnash::BufferedAudioStreamer::cleanAudioQueue(), and gnash::BufferedAudioStreamer::detachAuxStreamer().

Member Function Documentation

static unsigned int gnash::NetStream_as::audio_streamer	(	void *	udata,
		boost::int16_t *	samples,
		unsigned int	nSamples,
		bool &	eof
	)		`[static]`

Callback used by sound_handler to get audio data.

This is a sound_handler::aux_streamer_ptr type.

It might be invoked by a separate thread (neither main, nor decoder thread).

long gnash::NetStream_as::bufferLength ( )

Returns the number of millisecond of the media file that is buffered and yet to be played

Returns:: Returns the number of millisecond of the media file that is buffered and yet to be played

Referenced by update().

boost::uint32_t gnash::NetStream_as::bufferTime ( ) [inline]

Returns what the buffer time has been set to. (100 milliseconds is default)

Returns:: The size of the buffer in milliseconds.

long gnash::NetStream_as::bytesLoaded ( )

Returns the number of bytes of the media file that have been buffered.

long gnash::NetStream_as::bytesTotal ( )

Returns the total number of bytes (size) of the media file.

Returns:: the total number of bytes (size) of the media file

void gnash::NetStream_as::close ( )

Closes the video session and frees all ressources used for decoding except the FLV-parser (this might not be correct).

References gnash::BufferedAudioStreamer::cleanAudioQueue(), and gnash::BufferedAudioStreamer::detachAuxStreamer().

Referenced by play().

std::auto_ptr< image::GnashImage > gnash::NetStream_as::get_video ( )

Returns the video frame closest to current cursor. See time().

Returns:: a image containing the video frame, a NULL auto_ptr if none were ready

double gnash::NetStream_as::getCurrentFPS ( ) [inline]

Returns the current framerate in frames per second.

bool gnash::NetStream_as::isConnected ( ) const [inline]

Return true if the NetStream has an associated NetConnection.

void gnash::NetStream_as::markReachableResources ( ) const [virtual]

Mark any reachable resources other than the owner.

Override this function if the subclass holds references to GC resources other than the owner.

Reimplemented from gnash::ActiveRelay.

References gnash::ActiveRelay::setReachable(), and gnash::GcResource::setReachable().

void gnash::NetStream_as::pause ( PauseMode mode )

Pauses/starts the playback of the media played by the current instance.

Parameters:

mode	Defines what mode to put the instance in.

References _, pauseModeToggle, gnash::PlayHead::getState(), pauseModePause, and pauseModeUnPause.

void gnash::NetStream_as::play ( const std::string & source )

Starts the playback of the media.

Parameters:

source Defines what file to play

PlayHead::PlaybackStatus gnash::NetStream_as::playbackState ( ) const [inline]

References gnash::PlayHead::getState().

Referenced by gnash::Video::clear().

void gnash::NetStream_as::seek ( boost::uint32_t pos )

Seek in the media played by the current instance.

Parameters:

pos	Defines in seconds where to seek to

Todo:: take milliseconds !!

References GNASH_REPORT_FUNCTION, _, gnash::BufferedAudioStreamer::cleanAudioQueue(), and gnash::PlayHead::seekTo().

void gnash::NetStream_as::setAudioController ( DisplayObject * controller )

Make audio controlled by given DisplayObject.

References gnash::getRoot(), and gnash::ActiveRelay::owner().

void gnash::NetStream_as::setBufferTime ( boost::uint32_t time )

Specifies the number of milliseconds to buffer before starting to display the stream.

Parameters:

time	The time in milliseconds that should be buffered.

References time().

void gnash::NetStream_as::setInvalidatedVideo ( DisplayObject * ch ) [inline]

Register the DisplayObject to invalidate on video updates.

Referenced by gnash::Video::setStream().

void gnash::NetStream_as::setNetCon ( NetConnection_as * nc ) [inline]

Sets the NetConnection needed to access external files.

Parameters:

nc	The NetConnection object to use for network access

boost::int32_t gnash::NetStream_as::time ( )

Tells where the playhead currently is.

Returns:: The time in milliseconds of the current playhead position

References gnash::PlayHead::getPosition().

Referenced by setBufferTime().

void gnash::NetStream_as::update ( ) [virtual]

Called at the SWF heart-beat. Used to process queued status messages and (re)start after a buffering pause. In NetStreamFfmpeg it is also used to find the next video frame to be shown, though this might change.

Implements gnash::ActiveRelay.

int gnash::NetStream_as::videoHeight ( ) const

Get the real height of the video in pixels if the decoder exists.

Returns:: the height of the video in pixels or 0 if no decoder exists. The width returned from the decoder may also vary, and will be 0 until it knows the width.

Referenced by gnash::Video::height().

int gnash::NetStream_as::videoWidth ( ) const

Get the real width of the video in pixels if the decoder exists.

Returns:: the width of the video in pixels or 0 if no decoder exists. The width returned from the decoder may also vary, and will be 0 until it knows the width.
