bool cDvbHdFfDevice::CanReplay ( void  ) const

Returns true if this device can currently start a replay session.

References cDevice::CanReplay().

cRect cDvbHdFfDevice::CanScaleVideo ( const cRect Rect,
int  Alignment = taCenter 
)
virtual

Asks the output device whether it can scale the currently shown video in such a way that it fits into the given Rect, while retaining its proper aspect ratio.

If the scaled video doesn't exactly fit into Rect, Alignment is used to determine how to align the actual rectangle with the requested one. The actual rectangle can be smaller, larger or the same size as the given Rect, and its location may differ, depending on the capabilities of the output device, which may not be able to display a scaled video at arbitrary sizes and locations. The device shall, however, do its best to match the requested Rect as closely as possible, preferring a size and location that fits completely into the requested Rect if possible. Returns the rectangle that can actually be used when scaling the video. A skin plugin using this function should rearrange its content according to the rectangle returned from calling this function, and should especially be prepared for cases where the returned rectangle is way off the requested Rect, or even Null. In such cases, the skin may want to fall back to working with full screen video. The coordinates of Rect are in the range of the width and height returned by GetOsdSize(). If this device can't scale the video, a Null rectangle is returned (this is also the default implementation).

void cDvbHdFfDevice::Clear ( void  )

Clears all video and audio data from the device.

A derived class must call the base class function to make sure all registered cAudio objects are notified.

bool cDvbHdFfDevice::Flush ( int  TimeoutMs = 0)
virtual

Returns true if the device's output buffers are empty, i.

e. any data which was buffered so far has been processed. If TimeoutMs is not zero, the device will wait up to the given number of milliseconds before returning in case there is still data in the buffers.

void cDvbHdFfDevice::GetOsdSize ( int &  Width,
int &  Height,
double &  PixelAspect 
)
virtual

Returns the Width, Height and PixelAspect ratio the OSD should use to best fit the resolution of the output device.

If PixelAspect is not 1.0, the OSD may take this as a hint to scale its graphics in a way that, e.g., a circle will actually show up as a circle on the screen, and not as an ellipse. Values greater than 1.0 mean to stretch the graphics in the vertical direction (or shrink it in the horizontal direction, depending on which dimension shall be fixed). Values less than 1.0 work the other way round. Note that the OSD is not guaranteed to actually use this hint.

int64_t cDvbHdFfDevice::GetSTC ( void  )
virtual

Gets the current System Time Counter, which can be used to synchronize audio, video and subtitles.

If this device is able to replay, it must provide an STC. The value returned doesn't need to be an actual "clock" value, it is sufficient if it holds the PTS (Presentation Time Stamp) of the most recently presented frame. A proper value must be returned in normal replay mode as well as in any trick modes (like slow motion, fast forward/rewind). Only the lower 32 bit of this value are actually used, since some devices can't handle the msb correctly.

void cDvbHdFfDevice::GetVideoSize ( int &  Width,
int &  Height,
double &  VideoAspect 
)
virtual

Returns the Width, Height and VideoAspect ratio of the currently displayed video material.

Width and Height are given in pixel (e.g. 720x576) and VideoAspect is e.g. 1.33333 for a 4:3 broadcast, or 1.77778 for 16:9. The default implementation returns 0 for Width and Height and 1.0 for VideoAspect.

uchar * cDvbHdFfDevice::GrabImage ( int &  Size,
bool  Jpeg = true,
int  Quality = -1,
int  SizeX = -1,
int  SizeY = -1 
)
virtual

Grabs the currently visible screen image.

Size is the size of the returned data block. If Jpeg is true it will write a JPEG file. Otherwise a PNM file will be written. Quality is the compression factor for JPEG. 1 will create a very blocky and small image, 70..80 will yield reasonable quality images while keeping the image file size around 50 KB for a full frame. The default will create a big but very high quality image. SizeX is the number of horizontal pixels in the frame (default is the current screen width). SizeY is the number of vertical pixels in the frame (default is the current screen height). Returns a pointer to the grabbed image data, or NULL in case of an error. The caller takes ownership of the returned memory and must free() it once it isn't needed any more.

Scales the currently shown video in such a way that it fits into the given Rect.

Rect should be one retrieved through a previous call to CanScaleVideo() (otherwise results may be undefined). Even if video output is scaled, the functions GetVideoSize() and GetOsdSize() must still return the same values as if in full screen mode! If this device can't scale the video, nothing happens.

On indicates whether the PID shall be added or deleted. Handle->handle can be used by the device to store information it needs to receive this PID (for instance a file handle). Handle->used indicates how many receivers are using this PID. Type indicates some special types of PIDs, which the device may need to set in a specific way.

protectedvirtual
void cDvbHdFfDevice::SetVideoDisplayFormat ( eVideoDisplayFormat  VideoDisplayFormat)
virtual

Sets the video display format to the given one (only useful if this device has an MPEG decoder).

A derived class must first call the base class function! NOTE: this is only for SD devices. HD devices shall implement their own setup menu with the necessary parameters for controlling output.

void cDvbHdFfDevice::StillPicture ( const uchar Data,
int  Length 
)
virtual

Displays the given I-frame as a still picture.

Data points either to a series of TS (first byte is 0x47) or PES (first byte is 0x00) data of the given Length. The default implementation converts TS to PES and calls itself again, allowing a derived class to display PES if it can't handle TS directly.
