WARNING:
========
This is a developer version. Even though I use it in my productive
environment. I strongly recommend that you only use it under controlled
conditions and for testing and debugging.
This version introduces functions to determine the "signal strength"
and "signal quality" through cDevice. If you are using a DVB card that
contains an stb0899 frontend chip (like the TT-budget S2-3200) you may
want to apply the patches from
ftp://ftp.tvdr.de/vdr/Developer/Driver-Patches
to the LinuxDVB driver source in order to receive useful results from
that frontend.
Since apparently the various frontend drivers return different maximum
values in their FE_READ_SIGNAL_STRENGTH and FE_READ_SNR functions (some
deliver a value in the range 0x0000...0xFFFF, while others return values
as "dB/10" or "dBm/10" (the latter with an offset to make the value positive,
since the parameter is unsigned), the functions cDvbTuner::GetSignalStrength()
and cDvbTuner::GetSignalQuality() use the device's "subsystem ID" to
map these values into the range 0...100, which is the normalized return
value of these functions.
Take a look at these two functions and maybe remove the comment characters
from the lines
//#define DEBUG_SIGNALSTRENGTH
//#define DEBUG_SIGNALQUALITY
in dvbdevice.c to get some debug output if your device doesn't return any
directly useful values and may have to be added appropriately to the
'switch (subsystemId)' statement.
The channel display of the 'sttng' skin uses these values to implement
a signal strength/quality display.
From the HISTORY file:
- Fixed cString's operator=(const char *String) in case the given string is the
same as the existing one (thanks to Dirk Leber).
- Avoiding a gcc 4.6 compiler error in the skincurses plugin (thanks to Tobias Grimm).
- TsGetPayload() now checks if there actually is a payload in the given TS packet
(reported by Dirk Leber).
- Now sorting the source file names in the call to xgettext, to make sure the results
are not dependent on the sequence of the files.
Plugin authors may want to change the line containing the xgettext call in their
Makefile accordingly by changing "$^" to "`ls $^`".
- The primary device is now only avoided for recording if it is an old SD full
featured card. This is done through the new function cDevice::AvoidRecording().
- Subtitle PIDs are now also decrypted (thanks to Reinhard Nissl).
- Fixed a possible race condition in cDiseqc::Execute() (reported by Marco Göbenich).
The return value of cDiseqcs::Get() is now const, so plugin authors may need to
adjust their code if they use this function.
- The new functions cDevice::SignalStrength() and cDevice::SignalQuality() can be
used to determine the signal strength and quality of a given device (thanks to
Rolf Ahrenberg for some input on how to use BER and UNC values to generate a
"quality" value).
- The 'sttng' skin now displays two colored bars at the bottom of the channel display,
indicating the strength (upper bar) and quality (lower bar) of the received signal.
The number to the left of these bars indicates the actual device the current
channel is being received with.
- Fixed detecting frames in case the Picture Start Code or Access Unit Delimiter
extends over TS packet boundaries (reported by Johan Andersson).
In order to fix this, the semantics of cFrameDetector had to be changed a little.
See cRecorder::Action() and cIndexFileGenerator::Action() on how to use the new
cFrameDetector::NewPayload() function.
- The frame detector now only starts collecting PTS values after it has seen the
first I-frame, otherwise it might get MaxPtsValues values and stop analyzing
even though the incoming data is still garbage (reported by Derek Kelly).
- The info file of a recording is now only overwritten with a new fps value if
that new value is not the default value (thanks to Derek Kelly for reporting a
problem with the fps value being overwritten in case a recording was interrupted
and resumed, and the fps value could not be determined after resuming recording).
- The initial channel is now stored by the channel ID in the setup.conf file, in
order to avoid problems in case channels are reordered or deleted (reported by
Lars Bläser).
- Added support for "content identifier descriptor" and "default authority descriptor"
to 'libsi' (thanks to Dave Pickles).

- Updated the Estonian OSD texts (thanks to Arthur Konovalov).
- Fixed following symbolic links in RemoveFileOrDir() (cont'd) (thanks to
Steffen Barszus).
- Changed the description of cDevice::GetSTC() to make it mandatory for devices
that can replay.
- Removed the check for positive STC values from cDvbSubtitleConverter::Action().
- Added cString::operator=(const char *String) (suggested by Antti Seppälä).
- Some spelling fixes (thanks to Ville Skyttä).
- Passing package name and version to xgettext (thanks to Ville Skyttä).
- Made 'dist' target dependent on up to date *.po (thanks to Ville Skyttä).
- Added Language and fixed Language-Team header of *.po (thanks to Ville Skyttä).
- Updated the Lithuanian OSD texts (thanks to Valdemaras Pipiras).
- Fixed detecting frames on channels that broadcast with 50 or 60 fps.
This avoids artifacts during fast forward/rewind when replaying recordings from such
channels. To fix the index of existing recordings from such channels, just delete the
'index' file of the recording and VDR will generate a new one the next time you play it.
You should also change the line "F 25" to "F 50" in the 'info' file of that recording.
- Added support for "registration descriptor" to 'libsi' and using it in pat.c (thanks
to Rolf Ahrenberg).
- Fixed unjustified log entries about changed channel pids (reported by Derek Kelly).
- Added an include of VDR's 'Make.global' to libsi's Makefile (thanks to Rolf
Ahrenberg).
- Removed displaying the "contents" information from the "Classic VDR" and
"ST:TNG Panels" skins, because it is often wrong and nothing but irritating.
- Added typecasts to avoid gcc 4.5 warnings in switch statements on eKeys
variables where additional 'k_...' flags are used.
- Fixed inclusion of <stdarg.h> (thanks to Henning Heinold).
- Changed "frame duration" to "frame rate" in vdr.5 (reported by Tobias Grimm).
- Removing a cRemote from the Remotes list in case its initialization failed (thanks
to Dominik Strasser).
- Added LDFLAGS to the linker calls in the Makefiles (thanks to Joerg Bornkessel and
Paul Menzel).
- Now updating the 'frames per second' data in the list of recordings when a new
recording is started that has a frame rate other than the default.
- The include path to the freetype2 header files is now retrieved via a call to
'pkg-config --cflags freetype2' (suggested by Andreas Oberritter).
- The OSD now has full TrueColor support. There can be several "pixmaps" that can
be overlayed with alpha blending. All existing skins should work out of the box
with the TrueColor OSD - the only exception being cOsd::GetBitmap(). Since the
TrueColor OSD doesn't use bitmaps, this function will return a dummy bitmap, which
may not be what the plugin expects. As long as this bitmap is only used for setting
the palette, there is no problem. However, any other operations on this bitmap will
have no effect. See the description of the cPixmap functions in osd.h for details
about the new functionalities.
The "ST:TNG Panels" skin has been enhanced to automatically use the TrueColor OSD
if available.
The "osddemo" plugin has been extended to show some of the possibilities of the
TrueColor OSD if it is run on a system that actually provides TrueColor support.
Thanks to Reinhard Nissl for some valuable input, help with debugging, and an
implementation of the AlphaBlend() function.
- Updated the Slovakian language texts (thanks to Milan Hrala).
- Added Serbian language texts (thanks to Milan Cvijanovic).
- Fixed reallocating memory in the "pictures" plugin (reported by Paul Menzel, with
input from Oliver Endriss).
- Fixed reallocating memory in cTsToPes::PutTs() (suggested by Oliver Endriss).
- Now checking the result of all realloc() calls.
- Fixed setting up the 'Recordings' menu in case there are several recordings
with exactly the same name (reported by Marcus Hilbrich).
- Setting the audio type of language descriptors to 0x00 in the PAT/PMT generator
(thanks to Anssi Hannula).
- Changed the compiler optimization flag to -O3, which gives quite a performance
boost in the AlphaBlend() function.
- While replaying, the editing marks are now updated every 10 seconds (based on a
patch from Manuel Reimer).
- Now reducing the thread and I/O priority cCuttingThread::Action() to make the
foreground process more responsive (suggested by Frank Neumann).
- Removed checking for minimum line length of 21 characters in the LIRC receiver code
(reported by Gerald Dachs).
- Updated the Romanian OSD texts (thanks to Lucian Muresan).
- Now storing the original display size when handling DVB subtitles (thanks to
Reinhard Nissl).
- The original display size of subtitles is now used to scale them properly when
displaying them on an HD OSD.

- Updated the Italian OSD texts (thanks to Diego Pierotto).
- Changed the position of Sirius 4 to S4.8E in sources.conf (thanks to Alexander Gross).
- Updated the Finnish OSD texts (thanks to Rolf Ahrenberg).
- Moved the declaration of cMenuCommands to menu.h, so that plugins can use it.
- Added a note to the MANUAL, saying that adding new transponders only works if the
"EPG scan" is active (suggested by Halim Sahim).
- Improved handling frames at the beginning and end of a recording in cDvbPlayer for
devices with large buffers (thanks to Reinhard Nissl).
- Implemented cDeviceHook to allow plugins more control over which device can
provide which transponder (thanks to Reinhard Nissl).
- Implemented cDevice::GetCurrentlyTunedTransponder() (thanks to Reinhard Nissl).
- Moved strictly necessary Makefile options into Make.global, which is included
by all plugins (thanks to Paul Menzel). The Makefiles of existing plugins should be
modified like this:

- Added device definitions to the diseqc.conf file format, so that certain satellite
positions can be limited to a given list of devices.
This obsoletes the SOURCECAPS patch.
- Keeping subtitles visible when pausing replay (thanks to Rolf Ahrenberg).
- Fixed adding new transponders in case there is only a single channel in the
channel list (reported by Halim Sahin).
- The file name in the "Timers" menu now shows only the base name of the recording
without the folder path (if any). Otherwise with long folder paths the actual
recording name was not visible at all.
- Updated the Romanian OSD texts (thanks to Lucian Muresan).
- Exported some libsi functions (thanks to Lucian Muresan).
- Improved scalability of the default skins.
- Fixed the German translation of "Folder name must not contain '%c'!" (thanks to
Frank Schmirler).
- Updated the Estonian OSD texts (thanks to Arthur Konovalov).
- Plugins can now define new sources. In order to implement this, the following
changes were made:
+ The transponder parameter string is no longer interpreted by cChannel, but rather
stored as is and used only by the respective device. That way plugins can use a
channel's parameter string to store arbitrary data (see vdr.5).
+ The new class cSourceParam can be used by plugins to define new sources, and to
implement OSD items that will be used in the channel editor for editing the source
specific parameters of a channel (see dvbdevice.c for an example of how this is
done for the default DVB devices).
+ Purely numerical values are no longer accepted in the 'source' parameter of a
channel.
This obsoletes the PLUGINPARAM patch.
- Updated the Lithuanian OSD texts (thanks to Valdemaras Pipiras).
- cSafeFile::Close() now flushes the file (suggested by Stephan Austermühle).
- The option "Setup/DVB/Use Dolby Digital" now only controls whether Dolby Digital
tracks appear in the "Audio" menu. Dolby Digital is always recorded.
This obsoletes the DOLBYINREC patch.

- Updated the Italian OSD texts (thanks to Diego Pierotto).
- Fixed wrong bracketing in cChannel::SubtitlingType() etc.
(thanks to Rolf Ahrenberg).
- Fixed not logging changes for channels that have no number
(reported by Timothy D. Lenz).
- Changed the project's URLs and email to tvdr.de.
- Added Lithuanian language translations (thanks to Valdemaras Pipiras).
- Updated Chinese language texts (thanks to Nan Feng).
- Only checking DVB_API_VERSION to be >=5 in order to stay compileable in case
the DVB API version number is increased (the API claims to always be backward
compatible).
- Fixed saving terminal settings when running in background (thanks to Manuel
Reimer).
- Fixed cFrameDetector::Analyze() to handle video streams where the frame type
is not detectable from the first TS packet of a frame.
- Fixed writing the PCR pid into the PMT in cPatPmtGenerator::GeneratePmt()
(reported by Rene van den Braken).
- Added Slovakian language texts (thanks to Milan Hrala).
- Fixed EntriesOnSameFileSystem() to avoid using f_fsid, which may be 0 (thanks
to Frank Schmirler).
- Fixed starting a recording at an I-frame.
- Fixed generating the index for recordings from channels that put a whole
GOP into one payload unit.
- The index file for TS recordings is now regenerated on-the-fly if a
recording is replayed that has no index. This can also be used to
re-create a broken index file by manually deleting the index file and then
replaying the recording (at least until the index file has been generated).
- The cRingBufferLinear::Read() function now returns -1 and sets errno to
EAGAIN if the buffer is already full.
- Fixed handling DVB subtitles for PES recordings (thanks to Rolf Ahrenberg).
- Added the audio id to the call of PlayAudio() in cDevice::PlayTsAudio()
(thanks to Andreas Schaefers).
- Fixed references to old *.vdr file names in MANUAL (reported by Arthur Konovalov).
- Reverted "Removed limitation to PAL resolution from SPU handling" because it
cause nothing but trouble. Besides, the core VDR doesn't use this, anyway.
- Fixed the default value for "Pause key handling" in the MANUAL (reported by
Diego Pierotto).

- Re-implemented handling of DVB-S2, which first appeared in version 1.5.14, but was
revoked in version 1.5.15 in favor of making a stable version 1.6.0. VDR now
requires the "multiproto" DVB driver, e.g. from http://jusst.de/hg/multiproto.
Note that the channels.conf file now supports additional parameters, so you may
want to make sure you have a backup of this file in case you need to go back to
the previous version of VDR!
- Fixed displaying transponder data when it is modified (thanks to Reinhard Nissl).
- Fixed handling the counter in detection of pre 1.3.19 PS data (thanks to Reinhard
Nissl).
- Improved logging system time changes to avoid problems on slow systems under
heavy load (suggested by Helmut Auer).
- Now setting the thread name, so that it can be seen in 'top -H' (thanks to Rolf
Ahrenberg).
- Fixed initializing the timer's flags in the cTimer copy constructor (thanks to
Andreas Mair).
- Fixed setting the OSD level in the 'osddemo' example (thanks to Wolfgang Rohdewald).
- Increased the time between checking the CAM status to 500ms to avoid problems
with some CAMs (reported by Arthur Konovalov).

- Fixed the declaration of cSubtitleObject::Decode8BppCodeString() (thanks to
Gregoire Favre).
- The new setup option "Miscellaneous/Emergency exit" can be used to turn off
the automatic restart of VDR in case a recording fails for some reason.
- The kInfo key is now propagated to any open menu, so that it can react to it
in a context sensitive manner (suggested by Andreas Brugger). If there is
no menu open it will show the info of the current broadcast or replay.
- cTimeMs now uses the monotonic clock, if available (thanks to Petri Hintukainen).
- Fixed cVector::Clear() and cStringList::Clear().
- Added cString::Truncate().
- Fixed the "i18n:" target in the "newplugin" script, so that it can create the
initial *.pot file.
- Fixed handling the '-l' option.
- Fixed error handling in cCuttingThread::Action() (thanks to Udo Richter).
- Fixed a loss of the date display in the "classic" skin's main menu (reported by
Andreas Brugger).
- Added a missing setting of lastFreeMB in cMenuMain::Update() (reported by
Andreas Brugger).
- Added '-Wno-parentheses' to the compiler options in order to avoid silly compiler
warnings for expressions like 'a || b && c', where GCC 4.3 wants to force the
programmer to write 'a || (b && c)', while everybody knows that '&&' links
stronger than '||' (reported by Tobias Grimm).
- Updated the Hungarian language texts (thanks to István Füley).
- Fixed displaying weekday names in the Schedule menu if the system uses UTF-8
(reported by Jiri Dobry).
- The new plugin "pictures" implements a simple picture viewer.
See PLUGINS/src/pictures/README for details.
- The automatic shutdown is now suppressed if the remote control is currently
disabled (suggested by Helmut Auer, implemented by Udo Richter).
- Added a section about "Logging" to PLUGINS.html (suggested by Torsten Kunkel).
- Enhanced the SVDRP command CLRE to allow clearing the EPG data of a particular
channel (thanks to Benjamin Hess).
