<hr><h2>Devices</h2>
<center><i><b>Expanding the possibilities</b></i></center><p>
By default VDR is based on using DVB PCI cards that are supported by the
LinuxDVB driver. However, a plugin can implement additional devices that
can be used as sources of MPEG data for viewing or recording, and also
as output devices for replaying. Such a device can be a physical card
that is installed in the PC (like, for instance, an MPEG encoder card that
allows the analog signal of a proprietary set-top box to be integrated
into a VDR system; or an analog TV receiver card, which does the MPEG encoding
"on the fly" - assuming your machine is fast enough), or just a software program that takes an MPEG data
stream and displays it, for instance, on an existing graphics adapter.
<p>
To implement an additional device, a plugin must derive a class from cDevice:
<p><table><tr><td bgcolor=#F0F0F0><pre><br>
#include &lt;vdr/device.h&gt;
class cMyDevice : public cDevice {
...
};
</pre></td></tr></table><p>
The derived class must implement several virtual functions, according to
the abilities this new class of devices can provide. See the comments in the
file <tt>VDR/device.h</tt> for more information on the various functions,
and also <tt>VDR/dvbdevice.[hc]</tt> for details on the implementation of
the <tt>cDvbDevice</tt>, which is used to access the DVB PCI cards.
<p>
<b>Channel selection</b>
<p>
If the new device can receive, it most likely needs to provide a way of
selecting which channel it shall tune to:
<p><table><tr><td bgcolor=#F0F0F0><pre><br>
virtual bool SetChannelDevice(const cChannel *Channel);
</pre></td></tr></table><p>
This function will be called with the desired channel and shall return whether
tuning to it was successful.
<p>
<b>Recording</b>
<p>
A device that can be used for recording must implement the functions
<p><table><tr><td bgcolor=#F0F0F0><pre><br>
virtual bool SetPid(cPidHandle *Handle, int Type, bool On);
virtual bool OpenDvr(void);
virtual void CloseDvr(void);
virtual int GetTSPacket(uchar *Data);
</pre></td></tr></table><p>
which allow VDR to set the PIDs that shall be recorded, set up the device fro
recording (and shut it down again), and receive the MPEG data stream. The data
must be delivered in the form of a Transport Stream (TS), which consists of
packets that are all 188 bytes in size. Each call to <tt>GetTSPacket()</tt>
must deliver exactly one such packet (if one is currently available).
<p>
If this device allows receiving several different data streams, it can
implement
<p><table><tr><td bgcolor=#F0F0F0><pre><br>
virtual bool CanBeReUsed(int Frequency, int Vpid);
</pre></td></tr></table><p>
to indicate this to VDR.
<p>
<b>Replaying</b>
<p>
The functions to implement replaying capabilites are
<p><table><tr><td bgcolor=#F0F0F0><pre><br>
virtual bool HasDecoder(void) const;
virtual int SetPlayMode(bool On);
virtual void TrickSpeed(int Speed);
virtual void Clear(void);
virtual void Play(void);
virtual void Freeze(void);
virtual void Mute(void);
virtual void StillPicture(const uchar *Data, int Length);
virtual int PlayVideo(const uchar *Data, int Length);
</pre></td></tr></table><p>
In addition, the following functions may be implemented to provide further
functionality:
<p><table><tr><td bgcolor=#F0F0F0><pre><br>
virtual bool GrabImage(const char *FileName, bool Jpeg = true, int Quality = -1, int Si
virtual void SetVideoFormat(bool VideoFormat16_9);
virtual void SetVolumeDevice(int Volume);
</pre></td></tr></table><p>
<b>Initializing new devices</b>
<p>
A derived cDevice class shall implement a static function
<p><table><tr><td bgcolor=#F0F0F0><pre><br>
static bool Initialize(void);
</pre></td></tr></table><p>
in which it determines whether the necessary hardware to run this sort of
device is actually present in this machine (or whatever other prerequisites
might be important), and then creates as many device objects as necessary.
See <tt>VDR/dvbdevice.c</tt> for the implementation of the <tt>cDvbDevice</tt>
initialize function.
<p>
A plugin that adds devices to a VDR instance shall call this initializing
function from its <a href="#Getting started"><tt>Start()</tt></a> function.
<p>
Nothing needs to be done to shut down the devices. VDR will automatically
shut down (delete) all devices when the program terminates. It is therefore
important that the devices are created on the heap, using the <tt>new</tt>
operator!
