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

endOfMedia()

void Phonon::Experimental::VideoDataOutput2::endOfMedia ( )

overrideprotectedvirtual

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

Implements Phonon::Experimental::AbstractVideoDataOutput.

Definition at line 47 of file videodataoutput2.cpp.

endOfMediaSignal

void Phonon::Experimental::VideoDataOutput2::endOfMediaSignal ( )

signal

This signal is emitted after the last frameReady signal of a media is emitted.

frameReady()

void Phonon::Experimental::VideoDataOutput2::frameReady ( const VideoFrame2 & )

overrideprotectedvirtual

This function is called whenever a frame should be displayed.

Warning

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.

Implements Phonon::Experimental::AbstractVideoDataOutput.

Definition at line 42 of file videodataoutput2.cpp.

frameReadySignal

void Phonon::Experimental::VideoDataOutput2::frameReadySignal ( const Phonon::Experimental::VideoFrame2 & )

signal

The signal is emitted whenever a frame should be displayed.

nowStamp is the current time, outStamp tells the users what time the frame should be displayed with.

The relevant frames should be fetched and displayed using frameForTime method.
