vdr/dvbdevice.h
Klaus Schmidinger 523c4a07aa Version 1.1.9
- Fixed the 'newplugin' script to make it name the target for creating the
  distribution package 'dist', as stated in the PLUGINS.html documentation.
  If you have already created a plugin source directory and Makefile you may
  want to check it and replace the 'package' target with 'dist' if necessary.
- Changed device handling for being able to do simultaneous recording and
  replay on the same device (Time Shifting). In order for this to work you need
  to use a driver with a firmware version that has this feature implemented.
- cDevice::ProvidesCa() is no longer virtual. The new function
  cDevice::ProvidesChannel() is now used to determine whether a device can
  receive a given channel, and by default this function returns false. So a
  device that is a pure replaying device doesn't need to do anything here.
- Increased the recorder buffer size to 5MB in order to be able to better handle
  multiple recordings.
- Implemented cTSBuffer for better handling TS packet buffering in derived
  cDevice classes.
- Changed the interface if cDevice::GetTSPacket() to avoid unnecessary copying
  of data.
- Removed cDevice::Channel(), since this makes no more sense with devices
  receiving multiple channels.
- Switching through channels with the 'Up' and 'Down' keys now skips channels
  that are currently not available (for instance because all devices are
  recording and these channels are on different transponders).
- Implemented an SPU decoder (thanks to Andreas Schultz).
- Fixed a crash when entering an integer value outside the limits (thanks to
  Stefan Huelswitt for reporting this one).
- Added play mode pmAudioOnlyBlack (thanks to Stefan Huelswitt).
