Detailed Description

Functions to get available TV or Radio channels
These are mandatory functions for using this addon to get the available channels.

Remarks: Either SetSupportsTV() or SetSupportsRadio() is required to be set to true.
If a channel changes after the initial import, or if a new one was added, then the add-on should call TriggerChannelUpdate().

Channel parts in interface:
Copy this to your project and extend with your parts or leave functions complete away where not used or supported.

Function Documentation

◆ GetChannels()

virtual PVR_ERROR kodi::addon::CInstancePVRClient::GetChannels	(	bool	radio,
		kodi::addon::PVRChannelsResultSet &	results )

inlinevirtual

Request the list of all channels from the backend.

Parameters

[in]	radio	True to get the radio channels, false to get the TV channels.
[out]	results	The channels defined with class PVRChannel and available at the addon, them transferred with class PVRChannelsResultSet.

Returns: PVR_ERROR_NO_ERROR if the list has been fetched successfully.

The following table contains values that can be set with class PVRChannel :

Name	Type	Set call	Get call	Usage
Unique id	`unsigned int`	SetUniqueId	GetUniqueId	required to set
Is radio	`bool`	SetIsRadio	GetIsRadio	required to set
Channel number	`unsigned int`	SetChannelNumber	GetChannelNumber	optional
Sub channel number	`unsigned int`	SetSubChannelNumber	GetSubChannelNumber	optional
Channel name	`std::string`	SetChannelName	GetChannelName	optional
Mime type	`std::string`	SetMimeType	GetMimeType	optional
Encryption system	`unsigned int`	SetEncryptionSystem	GetEncryptionSystem	optional
Icon path	`std::string`	SetIconPath	GetIconPath	optional
Is hidden	`bool`	SetIsHidden	GetIsHidden	optional
Has archive	`bool`	SetHasArchive	GetHasArchive	optional
Order	`int`	SetOrder	GetOrder	optional
Client provider unique identifier	`int`	SetClientProviderUid	GetClientProviderUid	optional

Remarks: If PVRCapabilities::SetSupportsTV() is set to true, a valid result set needs to be provided for radio = false.
If PVRCapabilities::SetSupportsRadio() is set to true, a valid result set needs to be provided for radio = true. At least one of these two must provide a valid result set.

Example:

...
PVR_ERROR CMyPVRInstance::GetChannels(bool radio, kodi::addon::PVRChannelsResultSet& results)
{
  // Minimal demo example, in reality bigger and loop to transfer all
  kodi::addon::PVRChannel channel;
  channel.SetUniqueId(123);
  channel.SetIsRadio(false);
  channel.SetChannelNumber(1);
  channel.SetChannelName("My channel name");
  ...
 
  // Give it now to Kodi
  results.Add(channel);
  return PVR_ERROR_NO_ERROR;
}
...

◆ GetChannelsAmount()

virtual PVR_ERROR kodi::addon::CInstancePVRClient::GetChannelsAmount ( int & amount )

inlinevirtual

The total amount of channels on the backend.

Parameters

[out] amount The total amount of channels on the backend

Returns: PVR_ERROR_NO_ERROR if the amount has been fetched successfully.

Remarks: Valid implementation required.

◆ GetChannelStreamProperties()

virtual PVR_ERROR kodi::addon::CInstancePVRClient::GetChannelStreamProperties	(	const kodi::addon::PVRChannel &	channel,
		std::vector< kodi::addon::PVRStreamProperty > &	properties )

inlinevirtual

Get the stream properties for a channel from the backend.

Parameters

[in]	channel	The channel to get the stream properties for.
[out]	properties	the properties required to play the stream.

Returns: PVR_ERROR_NO_ERROR if the stream is available.

Remarks: If SetSupportsTV or SetSupportsRadio are set to true and SetHandlesInputStream is set to false.

In this case the implementation must fill the property PVR_STREAM_PROPERTY_STREAMURL with the URL Kodi should resolve to playback the channel.

Note: The value directly related to inputstream must always begin with the name of the associated add-on, e.g. "inputstream.adaptive.manifest_update_parameter".

Example:

...
PVR_ERROR CMyPVRInstance::GetChannelStreamProperties(const kodi::addon::PVRChannel& channel,
                                                     std::vector<kodi::addon::PVRStreamProperty>& properties)
{
  ...
  properties.emplace_back(PVR_STREAM_PROPERTY_INPUTSTREAM, "inputstream.adaptive");
  properties.emplace_back("inputstream.adaptive.manifest_type", "mpd");
  properties.emplace_back("inputstream.adaptive.manifest_update_parameter", "full");
  properties.emplace_back(PVR_STREAM_PROPERTY_MIMETYPE, "application/xml+dash");
  return PVR_ERROR_NO_ERROR;
}
...
