Function Documentation

◆ Activate()

void cPipReceiver::Activate ( bool on )

protectedvirtual

Called before the receiver gets attached or after it got detached.

Parameters

on	set on/off (unused)

Definition at line 59 of file pipreceiver.cpp.

References LOGDEBUG, and cPipReceiver::m_pTsToPesVideo.

◆ ChannelChange()

void cPipHandler::ChannelChange ( int direction )

Change the pip channel.

Parameters

direction 1: channel up, -1: channel down

Definition at line 389 of file pipreceiver.cpp.

References cPipHandler::m_active, cPipHandler::m_pEventReceiver, IEventReceiver::OnEventReceived(), PIPCHANDOWN, and PIPCHANUP.

Referenced by cSoftHdDevice::PipChannelChange().

◆ ChannelSwap()

void cPipHandler::ChannelSwap ( bool closePip )

Swap the pip channel with main live channel.

The channel switch of the main stream must be done out of OnEventReceived() because it triggers a SetPlayMode() which end in a deadlock otherwise.

Parameters

closePip close the pip window after the channel swap

Definition at line 160 of file pipreceiver.cpp.

◆ cPipReceiver()

cPipReceiver::cPipReceiver	(	const cChannel *	channel,
		cSoftHdDevice *	device
	)

Create a new receiver for the pip stream handling only video pid.

Parameters

channel	channel to receive
device	pointer to cSoftHdDevice object

Enable/ disable picture-in-picture.

Parameters

on	true, if pip should be enabled

◆ Start()

int cPipHandler::Start ( int channelNum )

private

Create a new pip receiver and render the pip stream.

Parameters

channelNum number of the channel to be switched to 0 switches to the current main stream channel

Return values

0	pip was enabled
-1	pip wasn't enabled, no device for channel available

Note: This function is called within the state change and must not trigger any new events!

◆ Stop()

void cPipHandler::Stop ( void )

private

Delete the pip receiver, clear decoder and display buffers and disable rendering the pip window.

We do not need to halt main stream decoder and display thread for this, so only halt the pip decoding thread here (in m_pDevice->ResetPipStream()) - not in OnEventReceived().
