Member Function Documentation

◆ ChannelChange()

void cPipHandler::ChannelChange ( int direction )

Change the pip channel.

Parameters

direction 1: channel up, -1: channel down

Definition at line 383 of file pipreceiver.cpp.

References m_active, 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 402 of file pipreceiver.cpp.

References LOGDEBUG, m_active, m_pEventReceiver, m_pPipChannel, IEventReceiver::OnEventReceived(), PIPCHANSWAP, and PIPSTOP.

Referenced by cSoftHdDevice::PipChannelSwap().

◆ Disable()

void cPipHandler::Disable ( void )

Stop picture-in-picture.

Definition at line 362 of file pipreceiver.cpp.

References m_active, m_pEventReceiver, IEventReceiver::OnEventReceived(), and PIPSTOP.

Referenced by cSoftHdDevice::PipDisable().

◆ Enable()

void cPipHandler::Enable ( void )

Start picture-in-picture.

Definition at line 351 of file pipreceiver.cpp.

References m_active, m_pEventReceiver, IEventReceiver::OnEventReceived(), and PIPSTART.

Referenced by cSoftHdDevice::PipEnable().

◆ HandleChannelChange()

void cPipHandler::HandleChannelChange ( int direction )

private

Change the pip channel.

Parameters

direction 1: channel up, -1: channel down

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

Definition at line 306 of file pipreceiver.cpp.

References m_active, m_pPipChannel, Start(), and Stop().

Referenced by HandleEvent().

◆ HandleEnable()

void cPipHandler::HandleEnable ( bool on )

private

Enable/ disable picture-in-picture.

Parameters

on	true, if pip should be enabled

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

Definition at line 282 of file pipreceiver.cpp.

References LOGDEBUG, m_active, m_pDevice, m_pipChannelNum, cSoftHdDevice::SetRenderPipActive(), Start(), and Stop().

◆ HandleEvent()

void cPipHandler::HandleEvent ( enum PipState event )

Handle a pip event.

Definition at line 175 of file pipreceiver.cpp.

◆ IsEnabled()

bool cPipHandler::IsEnabled ( void )

◆ SetSize()

void cPipHandler::SetSize ( void )

Set size and position for the pip window.

Definition at line 424 of file pipreceiver.cpp.

References m_pEventReceiver, IEventReceiver::OnEventReceived(), and PIPSIZECHANGE.

Referenced by cSoftHdDevice::PipSetSize().

◆ 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!

Definition at line 220 of file pipreceiver.cpp.

Referenced by HandleChannelChange(), HandleEnable(), and HandleEvent().

◆ 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().

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