Detailed Description

This class gives you the video data.

This class implements a special AbstractVideoOutput that gives your application the video data.

You can also use the video data for further processing (e.g. encoding and saving to a file).

Member Function Documentation

◆ allowedFormats()

QSet< VideoFrame2::Format > Phonon::Experimental::AbstractVideoDataOutput::allowedFormats ( ) const

Lists the formats this output is allowed to pass via frameReady.

Definition at line 50 of file abstractvideodataoutput.cpp.

◆ endOfMedia()

virtual void Phonon::Experimental::AbstractVideoDataOutput::endOfMedia ( )
pure virtual

This function is called after the last frameReady of a MediaObject was called.

Implemented in Phonon::Experimental::VideoDataOutput2.

◆ frameReady()

virtual void Phonon::Experimental::AbstractVideoDataOutput::frameReady ( const VideoFrame2 & )
pure virtual

This function is called whenever a frame should be displayed.

frameReady can get called from any thread (other than the main thread or the thread affinity of this QObject). A common error to create a deadlock situation is to block the thread this function is called from, until the main thread has found time to handle the frame. If it is blocking while the main thread decides to stop/delete the MediaObject you might get a deadlock.

Implemented in Phonon::Experimental::VideoDataOutput2.

◆ isRunning()

bool Phonon::Experimental::AbstractVideoDataOutput::isRunning ( ) const

Definition at line 62 of file abstractvideodataoutput.cpp.

◆ setAllowedFormats()

void Phonon::Experimental::AbstractVideoDataOutput::setAllowedFormats ( const QSet< VideoFrame2::Format > & allowedFormats)

Defaults to VideoFrame2::Format_RGB888.

Definition at line 56 of file abstractvideodataoutput.cpp.

◆ setRunning()

void Phonon::Experimental::AbstractVideoDataOutput::setRunning ( bool running)

Definition at line 68 of file abstractvideodataoutput.cpp.

◆ start()

void Phonon::Experimental::AbstractVideoDataOutput::start ( )

Definition at line 82 of file abstractvideodataoutput.cpp.

◆ stop()

void Phonon::Experimental::AbstractVideoDataOutput::stop ( )
