void cDvbHdFfDevice::Clear ( void  )

Clears all video and audio data from the device.

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.

cSpuDecoder * cDvbHdFfDevice::GetSpuDecoder ( void  )

Returns a pointer to the device's SPU decoder (or NULL, if this device doesn't have an SPU decoder).

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.

eVideoSystem cDvbHdFfDevice::GetVideoSystem ( void  )

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

Grabs the currently visible screen image.

Parameters
SizeThe size of the returned data block.
JpegIf true will write a JPEG file. Otherwise a PNM file will be written.
QualityThe 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.
SizeXThe number of horizontal pixels in the frame (default is the current screen width).
SizeYThe 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.

void cDvbHdFfDevice::MakePrimaryDevice ( bool  On)

Informs a device that it will be the primary device.

If there is anything the device needs to set up when it becomes the primary device (On = true) or to shut down when it no longer is the primary device (On = false), it should do so in this function. A derived class must call the MakePrimaryDevice() function of its base class.

protectedvirtual

Plays the given data block as audio.

Data points to exactly one complete PES packet of the given Length. Id indicates the type of audio data this packet holds. PlayAudio() shall process the packet either as a whole (returning Length) or not at all (returning 0 or -1 and setting 'errno' accordingly).

bool cDvbHdFfDevice::SetPid ( cPidHandle Handle,
int  Type,
bool  On 
)
protectedvirtual

Does the actual PID setting on this device.

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.

void cDvbHdFfDevice::SetVideoDisplayFormat ( eVideoDisplayFormat  VideoDisplayFormat)

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!

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

Displays the given I-frame as a still picture.

Data points either to 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.

void cDvbHdFfDevice::TrickSpeed ( int  Speed)
virtual

Sets the device into a mode where replay is done slower.

Every single frame shall then be displayed the given number of times. The cDvbPlayer uses the following values for the various speeds: 1x 2x 3x Fast Forward 6 3 1 Fast Reverse 6 3 1 Slow Forward 8 4 2 Slow Reverse 63 48 24
