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.

- Added Macedonian language texts (thanks to Dimitar Petrovski).
- Updated the Estonian OSD texts (thanks to Arthur Konovalov).
- Updated the Finnish OSD texts (thanks to Rolf Ahrenberg).
- Added handling of EnhancedAC3DescriptorTag (thanks to Eric Valette).
- The default SVDRP port is now 6419 (registered with ICANN/IANA by Christian Tramnitz).
Use '-p 2001' to switch back to the old port if necessary.
- Updated the Italian OSD texts (thanks to Diego Pierotto).
- cDvbDevice::ProvidesTransponder() now checks the modulation capabilities of the
device (as far as the driver allows this).
- Fixed cFrameDetector::Analyze() in case part of the data has been processed and
there is less than MIN_TS_PACKETS_FOR_FRAME_DETECTOR left (reported by Derek Kelly).
- Added a note about not deleting cDeviceHook objects to device.h.
- Added user defined key kUser0 (suggested by Ulf Kiener).
- Include paths are now added instead of overwriting INCLUDES in the Makefile (thanks
to Paul Menzel).
- The various modulation types are now taken into account when selecting a device for
a recording or live viewing, so that devices that provide more capabilities are
spared.
- Fixed generating PMT language descriptors for multi language PIDs (thanks to Rolf
Ahrenberg).
- Transponders that use "8psk turbo fec" (a non-standard mode used by North American
providers) are now identified by assuming that all 8psk transponders on DVB-S use
"turbo fec". In order to determine whether a certain device can handle "turbo fec",
the new driver flag FE_CAN_TURBO_FEC is checked. If your device can handle "turbo
fec", and your driver doesn't have that flag, yet, you can apply the patch from
ftp://ftp.tvdr.de/vdr/Developer/v4l-dvb-add-FE_CAN_TURBO_FEC.diff. A temporary
macro in dvbdevice.c defines the flag for all those who don't need this in the
driver, so that they can continue using an unmodified driver.
Thanks to Derek Kelly for testing this.
- Updated the Ukrainian OSD texts (thanks to Yarema Aka Knedlyk).
- Fixed handling "none" color entries in XPM files (thanks to Thomas Günther).
- Fixed a crash when creating a new channel if the channel list is empty (reported
by Halim Sahin).
- Updated the Czech OSD texts (thanks to Radek Stastny).
- Fixed a possible out of buffer memory access in case of bad TS data (reported
by Rolf Ahrenberg).
- Implemented handling of HD resolution subtitles according to v1.3.1 of
ETSI EN 300 743, chapter 7.2.1 (thanks to Rolf Ahrenberg).
- The EPG data now handles stream components 5 (H.264-video) and 6 (HEAAC-audio).
- Fixed a problem with external Dolby Digital processing via the '-a' option in live
mode and with TS recordings (reported by Christopher Reimer).
- Added handling MPEG audio types "ISO/IEC 14496-3 Audio with LATM transport syntax"
and "ISO/IEC 13818-7 Audio with ADTS transport syntax" (suggested by Luis Fernandes).
See man vdr(5) on how the APID section of channels has been extended to store
this information.
- Added detecting channels that use service type 0x16.
- Added full handling of the stream types of Dolby Digital pids
(thanks to Jose Alberto Reguero).
- The new setup option "OSD/Number keys for characters" can be used to control whether
the number keys can be used to enter characters in a text input field (suggested
by Stefan Huskamp).
