Constructor & Destructor Documentation

◆ POutputVideoStream() [1/2]

POutputVideoStream::POutputVideoStream ( )

Constructs an empty (no stream) video stream recorder; use POutputVideoStream::Open() factory to open an output video stream.

IsOpened() will return false.

See also: Open()

◆ POutputVideoStream() [2/2]

POutputVideoStream::POutputVideoStream ( const POutputVideoStream & other )

Constructs a shared copy of other.

◆ ~POutputVideoStream()

virtual POutputVideoStream::~POutputVideoStream ( )

virtual

Destroys this object; the stream will be automatically closed.

Member Function Documentation

◆ Close()

PResult POutputVideoStream::Close ( )

Closes this video stream.

Returns PResult::C_OK if success, another result otherwise.

See also: OpenVideoStream()

◆ GetUri()

PUri POutputVideoStream::GetUri ( ) const

Returns the URI corresponding to this stream.

◆ IsEmpty()

bool POutputVideoStream::IsEmpty ( ) const

Returns true if this output video stream is empty (output no video stream), false otherwise.

◆ IsOpened()

bool POutputVideoStream::IsOpened ( ) const

Returns true if the video stream has been successfully opened and is ready for writing, false otherwise.

◆ Open() [1/2]

static PResult POutputVideoStream::Open	(	const PString &	uri,
		POutputVideoStream &	outputVideoStream
	)

static

Factory: creates and opens an output video stream from the specified URI (this method is a factory).

By default, this factory will use the first plugin that can handle the specified URI.

Preferred encoding tool can be specified in the URI using "encode_with" parameter:

POutputVideoStream::Open("out.mp4?encode_with=ffmpeg", ovs);

Returns PResult::C_OK if success, another result otherwise.

This function is a shortcut for PPluginManagerOutputVideoStream::GetInstance().OpenOutputVideoStream(...).

◆ Open() [2/2]

static PResult POutputVideoStream::Open	(	const PPlugin &	plugin,
		const PUri &	uri,
		POutputVideoStream &	outputVideoStream
	)

static

Factory: creates and opens an output video stream from the specified URI (this method is a factory).

To open the video stream, the specified plugin will be used.

Preferred encoding tool can be specified in the URI using "encode_with" parameter:

POutputVideoStream::Open("out.mp4?encode_with=ffmpeg", ovs);

Returns PResult::C_OK if success, another result otherwise.

This function is a shortcut for PPluginManagerOutputVideoStream::GetInstance().OpenOutputVideoStream(...).

◆ OpenVideoStream()

PResult POutputVideoStream::OpenVideoStream ( )

Opens/re-opens this video stream.

Returns PResult::C_OK if success, another result otherwise.

See also: Close()

◆ operator=()

POutputVideoStream& POutputVideoStream::operator= ( const POutputVideoStream & other )

Performs a shared copy of other to this object.

◆ PutFrame()

PResult POutputVideoStream::PutFrame	(	const PFrame &	frame,
		papillon::int32	timeOutMs = `10000`
	)		const

Writes the specified frame to this video stream.

The method is blocking (synchronous). Returns PResult::C_OK if success, another result otherwise.
