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.

{
  // Minimal demo example, in reality bigger and loop to transfer all
  kodi::addon::PVRProvider provider;
  provider.SetUniqueId(123);
  provider.SetProviderName("My provider name");
  provider.SetProviderType(PVR_PROVIDER_TYPE_SATELLITE);
  ...
 
  // Give it now to Kodi
  results.Add(provider);
  return PVR_ERROR_NO_ERROR;
}
...

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");

◆ GetChannelStreamProperties()

virtual PVR_ERROR GetChannelStreamProperties	(	const kodi::addon::PVRChannel &	channel,
		PVR_SOURCE	source,
		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.
[in]	source	PVR_SOURCE_EPG_AS_LIVE if this call resulted from PVR_STREAM_PROPERTY_EPGPLAYBACKASLIVE being set from GetEPGTagStreamProperties(), DEFAULT otherwise
