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.
*** PLEASE BE VERY CAREFUL WHEN USING THIS DEVELOPER VERSION, ESPECIALLY
*** IF YOU ENABLE THE NEW SVDRP PEERING! KEEP BACKUPS OF ALL YOUR TIMERS
*** AND OBSERVE VERY CLOSELY WHETHER EVERYTHING WORKS AS EXPECTED. THIS
*** VERSION INTRODUCES SOME MAJOR CHANGES IN HANDLING GLOBAL LISTS AND
*** LOCKING, SO ANYTHING CAN HAPPEN! YOU HAVE BEEN WARNED!
The main focus of this developer version is on the new locking mechanism
for global lists, and the ability to handle remote timers.
Any plugins that access the global lists of timers, channels, schedules
or recordings, will need to be adjusted (see below for details). Please
do initial tests with plain vanilla VDR and just the output plugin you
need.
Known bugs/problems:
- After deleting the last recording in a sub folder, the cursor may not
be positioned correctly.
- Instant recordings and pausing live video don't (yet) use the default
SVDRP host for recording.
From the HISTORY file:
- The new function cOsd::MaxPixmapSize() can be called to determine the maximum size
a cPixmap may have on the current OSD. The 'osddemo' example has been modified
accordingly. Plugin authors may want to use this function in case they use pixmaps
that are larger than the full OSD size. The default implementation sets this limit
to 2048x2048 pixel.
- The Setup/CAM menu now displays which device an individual CAM is currently
assigned to (suggested by Frank Neumann).
- Added detection of 24fps (thanks to Thomas Reufer).
- Added a note about the VDR User Counter and VDR's facebook page to the README file.
- The dvbhddevice plugin is no longer part of the VDR source archive.
You can get the latest version of this plugin from the author's repository at
https://bitbucket.org/powARman/dvbhddevice.
- The dvbsddevice and rcu plugins are no longer part of the VDR source archive.
You can get the latest versions of these plugins from ftp://ftp.tvdr.de/vdr/Plugins.
- Added a section about Output Devices to the INSTALL file.
- Fixed setting the source value of newly created channels, in case the NIT is
received from a different, but very close satellite position (reported by Daniel
Ribeiro). The code for handling different NITs has been removed from nit.c, because
according to the DVB standard table id 0x40 carries only the NIT of the actual
network.
- Added some comment to cPixmap about the relation between OSD, ViewPort and DrawPort
(suggested by Thomas Reufer).
- Improved syncing on sections when parsing the NIT and SDT.
- Fixed scaling subtitles (their areas could sometimes extend outside the actual OSD).
- Reduced the priority of the "video directory scanner" thread (suggested by Thomas
Reufer) and checking cIoThrottle::Engaged() when it is running.
- The script that gets called for recordings is now also called right before a
recording is edited, with the first parameter being "editing" (suggested by
Dieter Ferdinand).
- The new setup option "OSD/Default sort mode for recordings" can be used to define
how recordings shall be sorted by default (either by time or by name, with "by time"
being the default). If a particular sort mode has been selected for a folder by
pressing '0', the default no longer applies to that folder. Repeating timers no
longer write a ".sort" file into a recordings folder to have the recordings sorted
by time.
- The command line option -D now accepts the value '-' (as in -D-), which prevents
VDR from using any DVB devices (suggested by Dietmar Spingler).
- The -V and -h options now list the plugins in alphabetical order (suggested by
Dietmar Spingler).
- Fixed a compiler warning in font.c.
- Commented out the line
#define DEPRECATED_VIDEOSYSTEM
in device.h. If a plugin doesn't compile with this version of VDR, you can uncomment
this line as a quick workaround. In the long run the plugin will need to be adapted.
- The function cOsd::GetBitmap() is now 'protected'. If a plugin doesn't compile with
this version of VDR, you can uncomment the line
//#define DEPRECATED_GETBITMAP
in osd.h as a quick workaround. In the long run the plugin will need to be adapted.
- The -u option now also accepts a numerical user id (suggested by Derek Kelly).
- The SVDRP port now accepts multiple concurrent connections. You can now keep an
SVDRP connection open as long as you wish, without preventing others from
connecting. Note, though, that SVDRP connections still get closed automatically
if there has been no activity for 300 seconds (configurable via
"Setup/Miscellaneous/SVDRP timeout (s)").
- The SVDRP log messages have been unified and now always contain the IP and port
number of the remote host.
- SVDRP connections are now handled in a separate "SVDRP server handler" thread,
which makes them more responsive. Note that there is only one thread that handles
all concurrent SVDRP connections. That way each SVDRP command is guaranteed to be
processed separately, without interfering with any other SVDRP commands that might
be issued at the same time. Plugins that implement SVDRP commands may need to take
care of proper locking if the commands access global data.
- VDR now sends out a broadcast to port 6419/udp, which was assigned to 'svdrp-disc'
by the IANA. VDRs listening on that port will automatically initiate an SVDRP
connection to the broadcasting VDR, and in turn send out a broadcast to make
other VDRs connect to them. That way all VDRs within the local network will
have permanent "peer-to-peer" SVDRP connections between each other. The
configuration in the svdrphosts.conf file is taken into account when considering
whether or not to respond to an SVDRP discover broadcast.
- The new SVDRP command PING is used by automatically established peer-to-peer
connections to keep them alive.
- The new function GetSVDRPServerNames() can be used to get a list of all VDRs
this VDR is connected to via SVDRP.
- The new function ExecSVDRPCommand() can be used to execute an SVDRP command on
one of the servers this VDR is connected to, and retrieve the result.
The helper functions SVDRPCode() and SVDRPValue() can be used to easily access
the codes and values returned by ExecSVDRPCommand().
- The cTimer class now has a new member named 'remote', which holds the name of the
remote server this timer will record on. If this is NULL, it is a local timer.
- Timers from other VDRs that are connected to this VDR via SVDRP are now
automatically fetched and stored in the global Timers list. In order for this
to work, all of the channels used by timers on the remote VDR must also be
defined on the local VDR (however, not necessarily in the same sequence).
Automatic channel syncing will be implemented later.
- The main menu of the LCARS skin now displays a small rectangle on the left side
of a timer if this is a remote timer. The color of that rectangle changes if
the timer is currently recording on the remote VDR.
- Accessing the global Timers list now has to be protected by proper locking,
because SVDRP commands are now executed in a separate thread.
The introduction of this locking mechanism required the following changes:
+ The new classes cStateLock and cStateKey are used to implement locking
with quick detection of state changes.
+ cConfig::cConfig() now has a parameter that indicates whether this list
requires locking.
+ The global lists of Timers, Channels, Schedules and Recordings are no longer
static variables. They are now pointers that need to be retrieved through
a call to cTimers::GetTimersRead/Write(), cChannels::GetChannelsRead/Write(),
cSchedules::GetSchedulesRead/Write() and cRecordings::GetRecordingsRead/Write(),
respectively.
+ References from/to link channels are now removed in cChannels::Del() rather
than cChannel::~cChannel(), to make sure the caller holds a proper lock.
+ cChannel::HasTimer() has been removed. This information is now retrieved
via cSchedule::HasTimer().
+ Several member functions of cChannel, cTimer, cMarks and cRecording have
been made 'const', and some of them are now available as both 'const' and
'non-const' versions.
+ The cChannel::Set...() functions are now 'bool' and return true if they have
actually changed any of the channels's members.
+ cChannels::SetModified() has been renamed to cChannels::SetModifiedByUser().
+ cChannels::Modified() has been renamed to cChannels::ModifiedByUser(), and
now has a 'State' parameter that allows the caller to see whether a channel
has been modified since the last call to this function with the same State
variable.
+ The macros CHANNELSMOD_NONE/_AUTO/_USER have been removed.
+ cMarks now requires locking via cStateKey.
+ cSortedTimers now requires a pointer to the list of timers.
+ cEvent::HasTimer() no longer scans the list of timers to check whether an event
is referenced by a timer, but rather keeps score of how many timers reference
it. This was necessary in order to avoid having to lock the list of timers from
within a cEvent.
+ The new class cListGarbageCollector is used to temporary store any objects deleted
from cLists that require locking. This allows pointers to such objects to be
dereferenced even if the objects are no longer part of the list.
+ cListBase::Contains() can be used to check whether a particular object is still
contained in that list.
+ Outdated events are no longer "phased out", but rather deleted right away and thus
taken care of by the new "garbage collector" of the list.
+ Deleted cRecording objects are no longer kept in a list of "vanished" recordings,
but are rather taken care of by the new "garbage collector" of the list.
+ cSchedules::ClearAll() has been removed. The functionality is now implemented
directly in cSVDRPServer::CmdCLRE().
+ tEventID has been changed to u_int16_t in order to make room for the new member
numTimers in cEvent.
+ cSchedule now has a member Modified(), which can be used with a State variable
to quickly determine whether this schedule has been modified since the last call
to this function with the same State variable.
+ cSchedulesLock has been removed. Locking the list of schedules is now done via
the cList's new locking mechanism.
+ The 'OnlyRunningStatus' parameters in cEpgHandler::BeginSegmentTransfer() and
cEpgHandler::EndSegmentTransfer() are now obsolete. They are still present in
the interface for backward compatibility, but may be removed in a future version.
Their value is always 'false'.
+ The constant tcMod is no longer used in cStatus::TimerChange(). The definition is
still there for backward compatibility.
Plugins that access the global lists of Timers, Channels, Recordings or Schedules
will need to be adapted as follows:
+ Instead of directly accessing the global variables Timers, Channels or Recordings,
they need to set up a cStateKey variable and call the proper getter function,
as in
cStateKey StateKey;
if (const cTimers *Timers = cTimers::GetTimersRead(StateKey)) {
// access the timers
StateKey.Remove();
}
and
cStateKey StateKey;
if (cTimers *Timers = cTimers::GetTimersWrite(StateKey)) {
// access the timers
StateKey.Remove();
}
See timers.h, thread.h and tools.h for details on this new locking mechanism.
+ There are convenience macros for easily accessing these lists without having
to explicitly set up a cStateKey and calling its Remove() function. These macros
have the form LOCK_*_READ/WRITE (with '*' being TIMERS, CHANNELS, SCHEDULES or
RECORDINGS). Simply put such a macro before the point where you need to access
the respective list, and there will be a pointer named Timers, Channels, Schedules
or Recordings, respectively, which is valid until the end of the current block.
+ If a plugin needs to access several of the global lists in parallel, locking must
always be done in the sequence Timers, Channels, Recordings, Schedules. This is
necessary to make sure that different threads that need to lock several lists at
the same time don't end up in a deadlock.
+ Some pointer variables may need to be made 'const'. The compiler will tell you
about these.
- cSectionSyncer has been improved to better handle missed sections.
- Added a missing initialization of 'seen' in cChannel's copy constructor.
- Background modifications of channels, timers and events are now displayed immediately
in the corresponding menus.
- cEIT now checks the version of the tables before doing any processing, which saves
a lot of locking and processing.
- If a timer is newly created with the Red button in the Schedule menu, and the timer
is presented to the user in the "Edit timer" menu because it will start immediately,
it now *must* be confirmed with "Ok" to set the timer. Otherwise the timer will not
be created.
- Recordings and deleted recordings are now scanned in a single thread.
- The new SVDRP command POLL is used by automatically established peer-to-peer
connections to trigger fetching remote timers.
- You can now set DumpSVDRPDataTransfer in svdrp.c to true to have all SVDRP
communication printed to the console for debugging.
- Added a missing 'const' to cReceiver::Receive(), to protect the given Data from
being modified.
- The SVDRP commands that deal with timers (DELT, LSTT, MODT, NEWT, NEXT and UPDT)
as well as any log messages that refer to timers, now use a unique id for each
timer, which remains valid as long as this instance of VDR is running. This means
that timers are no longer continuously numbered from 1 to N in LSTT. There may be
gaps in the sequence, in case timers have been deleted.
- The Timers menu now displays the name of the remote VDR in front of the timer's
file name, if this is a remote timer.
- The new options "Setup/Miscellaneous/SVDRP peering", ".../SVDRP host name" and
".../SVDRP default host" can be used to configure automatic peering between VDRs
in the same network. Peering is disabled by default and can be enabled by setting
"SVDRP peering" to "yes".
- The function cTimer::ToText() no longer returns a newline character at the end of
the string. The newline is now added by the caller as necessary. This was changed
because cTimer::ToText() is now also needed in a context where the terminating
newline can't be used. Consequently, cChannel::ToText() and cMark::ToText() have
been modified accordingly.
- All timer related response strings from SVDRP commands now use the channel ID
instead of channel numbers.
- The "Edit timer" menu now has a new parameter "Record on", which can be used to
select the VDR on which this timer shall record. Timers can be freely moved
between connected VDRs by simply selecting the desired machine in this field.
- The SVDRP command DELT no longer checks whether the timer that shall be deleted
is currently recording.
- The character 0x0D is now stripped from EPG texts (reported by Janne Pänkälä).
- The EPG scanner no longer moves the dish if there is a positioner.
- The 'newplugin' script now creates the 'po' subdirectory for translations (thanks
to Thomas Reufer).
- Skins can now implement cSkinDisplayMenu::MenuOrientation() to display horizontal
menus (thanks to Stefan Braun).
- Fixed a possible stack overflow in cListBase::Sort() (thanks to Oliver Endriss).
- Changed the description of the --chartab option in the INSTALL file to refer to
"DVB SI table strings" instead of "EPG data".
- The width and height of the OSD are now limited to the actual maximum dimensions
of the output device, taking into account the top and left offset.
- The new setup option "Recording/Record key handling" can be used to define
what happens if the Record key on the remote control is pressed during
live tv (suggested by Dietmar Spingler).
- Empty adaptation field TS packets are now skipped when recording (thanks to
Christopher Reimer, based on the "AFFcleaner" by Stefan Pöschel).

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.
The main focus of this version is on adding basic support for positioners
to control steerable satellite dishes. Manually controlling the dish position
and storing individual positions will follow later.
The fixes contained in this version will be released in a stable version 2.0.3
later, if there are no problems.
From the HISTORY file:
- Fixed initializing cDevice::keepTracks.
- Fixed an endless loop in cTextWrapper::Set() in case the given Width is smaller than
one character (reported by Stefan Braun).
- Removed all "modified since version 1.6" markers from PLUGINS.html.
- Added definitions for older DVB API versions, back until 5.0 (based on a patch from
Udo Richter).
- Changed cThread::SetIOPriority() from "best effort class" to "idle class" in order to
improve overall performance when an editing process is running (thanks to Jochen
Dolze).
- Fixed handling '/' and '~' in recording file names in case DirectoryEncoding is
used (thanks to Lars Hanisch).
- Changed the sign of the satellite position value in cSource to reflect the standard
of western values being negative. The new member function cSource::Position() can be
used to retrieve the orbital position of a satellite.
- Fixed multiple occurrences of the same directory in the recordings list in case there
are directories that only differ in non-alphanumeric characters (was broken by
"Fixed selecting the last replayed recording in the Recordings menu in case there
are folders and plain recordings with names that differ only in non-alphanumeric
characters" in version 1.7.36).
- Fixed displaying the frame number when setting an editing mark (thanks to Thomas
Günther).
- Fixed no longer generating any editing marks if the edited recording results in just
one single sequence (reported by Halim Sahin).
- Fixed an error message when parsing SCR values in diseqc.conf.
- Fixed an unexpected RCS version tag in the newplugin script.
- Fixed an endless loop in the DrawEllipse() functions for very small ellipses (reported
by Stefan Braun).
- Fixed a crash in the LCARS skin's main menu in case there is no current channel
(reported by Dominique Dumont).
- Added basic support for positioners to control steerable satellite dishes (based on
a patch from Seppo Ingalsuo and Ales Jurik).
+ Supports GotoN (aka "DiSEqC 1.2") and GotoX (aka "USALS").
+ The new DiSEqC command code 'P' can be used to instruct a positioner to move the
dish to the required satellite position. When a 'P' code is processed, further
execution of the remaining DiSEqC sequence (if any) is postponed until the positioner
has reached the new satellite position.
+ The new special source value of "S360E" can be used in diseqc.conf to indicate that
an entry using a positioner can move the dish to any requested position within its
range. Think of it as "full circle".
+ The devices a particular cDiseqc or cScr applies to are now stored directly in each
cDiseqc or cScr, respectively.
+ A plugin can implement a custom positioner control (see PLUGINS.html, section "Positioners").
+ The new function cSkinDisplayChannel::SetPositioner() can be implemented by skins to
show the user a progress display when the dish is being moved. The default implementation
calls SetMessage() with a string indicating the new position the dish is being moved to.
The LCARS skin shows a progress bar indicating the movement of the dish.
+ The new parameters "Site latitude", "Site longitude", "Positioner speed", and
"Positioner swing" in the "Setup/LNB" menu can be used to configure the necessary
values for a steerable dish.
+ The cDvbTuner now has a new status tsPositioning, in which it waits until a steerable
dish has reached its target position. Parsing SI data is paused until the target
position has been reached.
- The LCARS skin now shows the source value of the current channel in its channel display.
- Fixed asserting free disk space in the cutter.
- No longer trying to delete old recordings in AssertFreeDiskSpace() if the given
Priority is less than 1.
- Fixed handling LIRC events in case repeated events are lost.
- Fixed a possible crash when shutting down VDR while subtitles are being displayed
(reported by Ville Skyttä).
- cDevice::IsPrimaryDevice() now also checks whether the primary device actually has
a decoder and returns false otherwise. This should improve device allocation on
systems that are only used as a receiver and don't actually display anything.
- Increased the value of MAXRETRIES to 20 to reduce the probability of disturbances
in transfer mode.
- All bonded devices (except for the master) now turn off their LNB power completely
to avoid problems when receiving vertically polarized transponders (suggested by
Manfred Völkel and Oliver Endriss).
- Reverted the change from version 1.5.7 that made all logging go to LOG_ERR (thanks
to Christopher Reimer).
- Added Begin/EndSegmentTransfer() to the EPG handler interface (thanks to Jörg Wendel).
- The code for distributing recordings over several video directories is now
deprecated and disabled by default.
You can re-enable this feature by removing the comment sign ('//') from the beginning
of the line
//#define DEPRECATED_DISTRIBUTED_VIDEODIR // Code enclosed with this macro is ...
in the file videodir.c. Note, though, that this can only be a temporary workaround.
This feature will be completely removed in one of the next developer versions.
Distributing the video directory over several disks was a useful feature in times
when disks were still relatively small, but it also caused serious problems in case
one of the disks failed. Nowadays hard disks come in sizes measured in terabytes,
and tools like "mhddfs" can be used to combine several disks to form one large volume.
A recommended method for a relatively safe disk setup in a VDR system is to use two
1TB (or larger) disks and use them as a RAID-1 (mirrored). That way, if one disk
fails, you can replace it without data loss.

Approaching version 2.0.0:
==========================
If all goes well, there should be no more functional or API changes
before the final version 2.0.0. There will just be a few more fixes.
From the HISTORY file:
- Updated the Ukrainian OSD texts (thanks to Yarema Aka Knedlyk).
- Updated the Estonian OSD texts (thanks to Arthur Konovalov).
- Updated the Romanian OSD texts (thanks to Lucian Muresan).
- Updated the French OSD texts (thanks to Marc Perrudin, Bernard Jaulini and Peter
Münster).
- Updated the Macedonian OSD texts (thanks to Dimitar Petrovski).
- Fixed moving editing marks, so that they don't get overwritten with old values
through an update of the marks file.
- Removed an invalid line from channels.conf.terr (reported by Lars Hanisch).
- Fixed an unexpected k_Repeat key event after a k_Release in lirc.c.
- Fixed permissions of po/sr_SR.po (reported by Dominic Evans).
- Updated the Italian OSD texts (thanks to Diego Pierotto).
- Fixed using "Pause" and "Slow motion" near the end of a recording (replay stopped
a few seconds after the end of the recording file has been reached).
- Fixed selecting the last replayed recording in the Recordings menu in case there
are folders and plain recordings with names that differ only in non-alphanumeric
characters (reported by Andre Weidemann).
- Fixed the description of the OSD drawing functions DrawEllipse() (the values -5...-8
for the Quadrants parameter are not implemented).
- Made cOsd::DestroyPixmap() "NULL proof".
- Now deleting any previously allocated pixmaps in cOsd::SetAreas().
- Added demos of the DrawEllipse() and DrawSlope() function to the 'osddemo'
plugin (press '1' or '2', respectively).
- Updated the Lithuanian OSD texts (thanks to Valdemaras Pipiras).
- The timeout for trying to switch to a valid programme is now reset immediately once
a programme has been found.
- No longer checking for EOPNOTSUPP in cDvbTuner::GetSignalQuality() to avoid breaking
this function in case the driver suddenly decides to return a different errno value
if an operation is not supported.
- Moved the definition of TIMERMACRO_TITLE and TIMERMACRO_EPISODE from recording.h to
config.h and using them to initialize Setup.NameInstantRecord (avoids having the same
information in two places).
- Fixed the return value of cOsdProvider::StoreImage() in case there is no OSD provider.
- Fixed a crash in cMenuEditChanItem::Set() when entering a channel number that
doesn't exist (reported by Mikael Hübsch).
- Fixed displaying pending timers in "alert" mode in the LCARS skin.
- Added missing $(LDFLAGS) to the Makefile of the dvbhddevice plugin (thanks to Ville
Skyttä).
- Fixed some spellings in PLUGINS.html and Doxyfile (thanks to Ville Skyttä).
- Added '-p' to the cp command in the install-conf target of the Makefile (thanks to
Ville Skyttä).
- Added missing 'const' to cDevice::HasProgramme() and cDevice::HasLock().
- Fixed determining the priority of the primary device in case it is neither replaying
nor receiving a live channel (thanks to Matthias Senzel for reporting a problem with
switching back to live viewing after replay in a setup with device bonding).
- Removed all \return and \param tags from comment lines marked with "///<" for Doxygen.
There was only a rather small number of these, and I would probably always forget to
put them in place when writing future comments, so I decided to drop them entirely.
- Added Doxyfile.filter to have special characters escaped that would otherwise be
dropped by Doxygen (reported by Ville Skyttä).
- Using 'cat' instead of 'cp' to copy the Doxyfile to avoid problems in case Doxyfile
is write protected.
- Updated the Doxyfile with a newer version of Doxygen.
- Turned off following symlinks in the Doxyfile.
- Removed trailing whitespace.
- Expanded tabs in PLUGINS/src/dvbhddevice/setup.c.
- Some formatting fixes.
