from PyKDE4.phonon import *

Namespace: Phonon::Experimental

Detailed Description

A single video frame.

This simple class contains the data of a frame and metadata describing how to interpret the data.

Methods

int	aspectCorrectedWidth (self)
QImage	qImage (self)

int aspectCorrectedHeight ( self )

Convenience function to calculate the aspect corrected height from the aspectRatio and width values.

It is recommended to display video frames with aspectCorrectedWidth x height

int aspectCorrectedWidth ( self )

QImage qImage ( self )

float aspectRatio

Convenience function to calculate the aspect corrected width from the aspectRatio and height values.

It is recommended to display video frames with aspectCorrectedWidth x height

YV12 U-plane

If format is Format_YV12 the data contains one byte per four adjacent pixels with the Cb value.

YV12 V-plane

If format is Format_YV12 the data contains one byte per four adjacent pixels with the Cr value.

Phonon.Experimental.VideoFrame2.Format format

RGB8, YUY2 or Y-plane

If format is Format_RGB888 then the data contains each pixel as three consecutive bytes for red, green and blue.

If format is Format_YUY2 the data contains every two pixels as four consecutive bytes for Y0, Cb, Y1, Cr

If format is Format_YV12 the data contains one byte per pixel with the Y value.

int height

The aspect ratio the frame should be displayed with.

Common values are 4/3, 16/9.

int width

The height of the video frame in number of pixels.

Format

The frame is invalid.

Enumerator:

Format_Invalid = QImage::Format_Invalid The frame is invalid. < p>
Format_RGB888 = QImage::Format_RGB888
Format_YCbCr420 = 0x10000
Format_YV12 = Format_YCbCr420
Format_YCbCr422 = 0x10001
Format_YUY2 = Format_YCbCr422
