Version 1.5.1vdr-1.5.1
- Added cDevice::HasCi() so that devices with Common Interface can be avoided when tuning to an FTA channel, thus preserving the CAM resources even on budget DVB cards (suggested by Petri Helin). - Fixed i18n characters for the Hungarian texts (thanks to Thomas Günther). - Now using cPipe instead of popen() in cCommand::Execute() to avoid problems with open file handles when starting background commands (thanks to Reinhard Nissl). - Removed 'assert(0)' from cDvbSpuDecoder::setTime() (thanks to Marco Schlüßler). - Fixed a possible crash when loading an invalid XPM file (thanks to Martin Wache). - Updated satellite names in 'sources.conf' (thanks to Thilo Wunderlich). - Adapted 'libsi' to DVB-S2 (thanks to Marco Schlüßler). - Fixed handling error status in cDvbTuner::GetFrontendStatus() (thanks to Reinhard Nissl). - Shutdown handling has been rewritten (thanks to Udo Richter). - Plugins can now implement the new function WakeupTime() to request VDR to wake up at a particular time (thanks to Udo Richter). - The HUP signal now forces a restart of VDR (thanks to Udo Richter). - cThread::EmergencyExit() has been replaced by ShutdownHandler.RequestEmergencyExit(). - Several references to "button" in a remote control context have been changed to "key" (based on a report from Marko Mäkelä regarding the "Menu button closes" text). The "MenuButtonCloses" parameter in 'setup.conf' has therefore been renamed to "MenuKeyCloses", accordingly. This will result in an "unknown config parameter: MenuButtonCloses" error message in the log file, so you may want to remove that entry from your 'setup.conf' file. - Simplified the error handling in cDvbTuner::GetFrontendStatus() (based on a discussion with Reinhard Nissl). - Updated the Finnish OSD texts (thanks to Rolf Ahrenberg). - Increased the maximum number of DVB devices to 8 (thanks to Rolf Ahrenberg). - The new Setup parameter "Channel entry timeout" can be used to customize the time since the last keypress until a numerically entered channel number is considered complete, and the channel is switched (suggested by Helmut Auer). Setting this parameter to 0 turns off the automatic channel switching, and the user will have to confirm the entry by pressing the "Ok" key.
