Raw Blame History

This is a summary of the changes in VDR 2.2.0 since the last stable
version 2.0.0. It only contains things that are of actual importance
to the user and doesn't mention the many fixes and improvements that
have been made "behind the scenes".
See the file HISTORY for a detailed list of all changes.
Support for steerable satellite dishes:
- Added basic support for positioners to control steerable satellite dishes.
+ 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.
- 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.
Conditional Access:
- The new function cCamSlot::Decrypt() can be used by derived classes to implement a
CAM slot that can be freely assigned to any device, without being directly inserted
into the full TS data stream in hardware. A derived class that implements Decrypt()
will also need to set the new parameter WantsTsData in the call to the cCamSlot
base class constructor to true, in order to receive all the TS packets that
contain data necessary for decrypting.
- Many member functions of cCamSlot have been made virtual to allow for easier
implementation of derived classes.
- cDvbDevice::GetTSPacket() now calls CamSlot()->Decrypt() in order to allow CAM slots
that can be freely assigned to any device access to the TS data stream.
- Improved locking for CAM slots and made the pure functions of cCiAdapter have
default implementations, to fix a possible crash with CI adapters and CAM slots
that are implemented in a plugin.
- Added logging the supported system ids of a CAM.
- Now waiting explicitly until all CAM slots are ready before switching to the
initial channel when VDR is started. This is necessary in case CI adapters are
used that are not physically connected to a dedicated device. The respective checks
in cDvbDevice have been removed to avoid redundancy.
- Now unassigning CAMs from their devices when they are no longer used.
- Now making sure the primary device goes into transfer mode for live viewing if the
CAM wants to receive the TS data.
- Added a log message in case a receiver is detached from its device because the
assigned CAM can't decrypt the channel.
- The pid of the PMT in which the CA descriptors of a given channel are broadcast
is now stored together with the CA descriptors and can be retrieved by calling
GetPmtPid() (this information is only required to receive encrypted channels
with the OctopusNet receiver via the 'satip' plugin).
- Modified the CAM API so that it is possible to implement CAMs that can be freely
assigned to any devices.
- The Yellow button in the "Setup/CAM" menu can now be used to put the selected
CAM into a mode where it remains assigned to a device that is tuned to the current
channel until the smart card it contains is activated and the CAM thus starts to
descramble (see MANUAL, section "Setup/CAM" for details).
- Fixed cCamSlot::Assign(), so that it actually ignores the value of Query if Device
is NULL (as described in the header file).
Satellite Channel Routing:
- Added support for "Satellite Channel Routing" (SCR) according to EN50607, also
known as "JESS".
Subtitles:
- Improved displaying DVB subtitles.
- The debug output now goes into an HTML file named dbg-log.htm and shows the actual
bitmaps (dbg-nnn.jpg) used to display the subtitles. That way it is much easier to
see what's actually going on.
- The new function cOsd::DrawScaledBitmap() is now used for drawing subtitles.
This function can be reimplemented by high level OSDs which may be able to do
the scaling in hardware or otherwise more efficiently.
- Fixed (well, actually worked around) a problem with subtitles not being displayed
because the broadcaster doesn't set the data's version numbers as required by the
DVB standard.
- Added support for PGS subtitles.
Plugins:
- A plugin can implement a custom positioner control (see PLUGINS.html, section "Positioners").
- The new menu category mcRecordingEdit is now used to mark menus that edit recording
properties.
- The Recordings menu can now be called with a cRecordingFilter, which allows the
caller to have it display only a certain subset of the recordings.
- cDevice::TrickSpeed() now has an additional parameter named Forward, which indicates
the direction in which replay is being done. This information may be necessary for
some output devices in order to properly implement trick modes. Authors of plugins
that implement output devices will need to add this parameter to their derived cDevice
class, regardless of whether they will make use of it or not.
- Avoiding unnecessary pkg-config warnings in plugin Makefiles.
Plugin authors may want to apply the following change to their Makefile:
-PKGCFG = $(if $(VDRDIR),$(shell pkg-config --variable=$(1) $(VDRDIR)/vdr.pc),$(shell pkg-config --variable=$(1) vdr || pkg-config --variable=$(1) ../../../vdr.pc))
+PKGCFG = $(if $(VDRDIR),$(shell pkg-config --variable=$(1) $(VDRDIR)/vdr.pc),$(shell PKG_CONFIG_PATH="$$PKG_CONFIG_PATH:../../.." pkg-config --variable=$(1) vdr))
- The new function cStatus::ChannelChange() can be implemented by plugins to be
informed about changes to the parameters of a channel that may require a retune.
This may, for instance, be useful for plugins that implement live streaming, so that
they can react on changes to a channel's PIDs or CA descriptors.
- The new function cOsd::DrawScaledBitmap() is now used for drawing subtitles.
This function can be reimplemented by high level OSDs which may be able to do
the scaling in hardware or otherwise more efficiently.
- Use of the function cOsd::GetBitmap() outside of derived classes is now deprecated,
and it may be made 'protected' in a future version, since it doesn't work with
TrueColor OSDs. Plugin authors may want to modify their code so that it
works without this function.
- Modified the descriptions of several threads, so that the important information
(like device or frontend numbers) is within the first 15 characters of the
string, because only these are displayed in thread listings. Plugin authors may
want to do the same.
- Plugins can now implement the function SetMenuSortMode() in their skin objects
derived from cSkinDisplayMenu, to get informed about the currently used sort
mode, if applicable.
- Added cOsdProvider::OsdSizeChanged(), which plugins that implement an output device
can call to signal a change in the OSD that requires a redraw of the currently
displayed object.
Skins:
- 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 LCARS skin now shows the source value of the current channel in its channel display.
- Plugins can now implement the function SetMenuSortMode() in their skin objects
derived from cSkinDisplayMenu, to get informed about the currently used sort
mode, if applicable.
Remote control:
- Revised the section on "Learning the remote control keys" in the INSTALL file to
avoid the impression that there actually is a default remote.conf file, and to
not use any alphabetic keys for special functions, so that they remain available
for textual input.
- The LIRC remote control now connects to the socket even if it doesn't yet exist when
VDR is started.
- Added handling UTF-8 'umlaut' characters to cKbdRemote.
Devices:
- 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.
- 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.
- All bonded devices (except for the master) now turn off their LNB power completely
to avoid problems when receiving vertically polarized transponders.
- cDevice::TrickSpeed() now has an additional parameter named Forward, which indicates
the direction in which replay is being done. This information may be necessary for
some output devices in order to properly implement trick modes. Authors of plugins
that implement output devices will need to add this parameter to their derived cDevice
class, regardless of whether they will make use of it or not.
- Now checking whether the primary device actually has a decoder before retuning the
current channel after a change in its parameters. This fixes broken recordings on
the primary device on "headless" systems.
- Refactored setup parameter handling for output devices:
+ The function cDevice::GetVideoSystem() has been deprecated and will be removed
in a future version. In order to check whether a particular plugin needs to be
modified if this function is removed, you can comment out the line
#define DEPRECATED_VIDEOSYSTEM
in device.h.
+ Handling the "video (display) format" (things like 16:9, 4:3, pan&scan, letterbox
etc) shall now be done by the individual output devices, because the types and
numbers of parameters are too device specific. The Setup/DVB parameters
"Video format" and "Video display format" are still there for now and can be used
by SD devices. HD devices, however, shall not use these parameters (any more),
but rather implement their own setup menu with the necessary parameters for
controlling output.
+ The dvbhdffdevice plugin has been modified accordingly.
+ Made it clear that cDevice::SetDigitalAudioDevice() merely tells the output device
that the current audio track is Dolby Digital. This function was only used by the
original "full featured" DVB cards - do not use it for new developments!
If an output device has several ways of replaying audio (like HDMI or analog jack)
it shall implement the proper options in its plugin's SetupMenu() function.
- Added support for "Pilot", "T2-System-Id" and "SISO/MISO" parameters.
- Added subsystem id support for DVB devices connected via USB.
DiSEqC:
- 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.
EPG:
- Added Begin/EndSegmentTransfer() to the EPG handler interface.
OSD:
- In the "Select folder" menu pressing Ok now selects the folder, even if this is a
folder that contains sub folders (marked with "..."). To open such a folder you
can press the Red key.
- The Recordings menu now remembers the last recording the cursor was positioned on,
independent of the last replayed recording. When a replay ends, however, the cursor
will initially be positioned to the last replayed recording again when the menu
is opened.
- Added cOsdProvider::OsdSizeChanged(), which plugins that implement an output device
can call to signal a change in the OSD that requires a redraw of the currently
displayed object.
- The "Select folder" menu now adds the folder names of all existing recordings to
any names that have been predefined in "folders.conf".
- Fixed an inconsistent behavior between opening the Recordings menu manually via the
main menu and by pressing the Recordings key. In the latter case it automatically
opened all sub folders to position the cursor to the last replayed recording, which
is unexpected at this point. You can still navigate to
the last replayed recording (if any) by pressing Ok repeatedly in the Recordings
menu.
Channels:
- Channels that are no longer contained in the current SDT of a transponder are now
marked with the keyword OBSOLETE in their name and provider fields. That way you can
identify obsolete channels when you switch to them, and you can get the complete
overview of all obsolete channels by sorting the Channels list by provider (by
pressing the 0 key twice). Automatic deletion of obsolete channels may follow later.
- Added support for LCN (Logical Channel Numbers), which plugins may use to sort
channels.
- Added "NORDIG" to the list of "DVB/Standard compliance" options and using it to
restrict the LCN (Logical Channel Numbers) parsing to networks that actually use
this non-standard feature.
Recordings:
- The code for distributing recordings over several video directories has been
removed. VDR now by default assumes that the video directory is one big disk.
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.
- If you absolutely need to use several separate disks to store recordings, you can
write a plugin that uses the new cVideoDirectory API to implement the necessary
functionality (see PLUGINS.html, section "The video directory"). You can copy the
respective code from previous versions of videodir.c.
IMPORTANT NOTE: If you write a plugin that implements a distributed video directory,
=============== be sure to make cVideoDirectory::Rename() follow symbolic links!
This functionality was never implemented in VDR and it therefore
used a workaround in cutter.c. See the section marked with
// XXX this can be removed once RenameVideoFile() follows symlinks
in previous versions of cutter.c.
+ CloseVideoFile() is obsolete and has been removed.
+ The functions OpenVideoFile(), RenameVideoFile(), RemoveVideoFile(), VideoFileSpaceAvailable(),
VideoDiskSpace(), RemoveEmptyVideoDirectories(), IsOnVideoDirectoryFileSystem() and
PrefixVideoFileName() are now static members of cVideoDirectory and need to be called
with the proper prefix.
+ The name of the video directory is now available through cVideoDirectory::Name().
- Added renaming and moving recordings and folders, editing a recording's priority and
lifetime, and queueing cutting jobs.
+ The "Recording info" menu now has a new Blue button named "Edit", which opens a
dialog in which several properties of the selected recording can be changed. It can
be renamed or moved into another folder and its priority and lifetime can be
modified.
The new blue "Edit" button in the "Recordings" menu opens a dialog in which a folder
can be renamed or moved. See MANUAL, section "Managing folders".
+ In the "Edit recording" menu the Yellow button ("Delete marks") allows you to delete
all editing marks of the selected recording.
+ cCutter is no longer a static class. Cutting requests should now be invoked by
calling RecordingsHandler.Add(ruCut, FileName). See the new cRecordingsHandler
class in recording.h.
+ Cutting jobs are now placed in a queue (together with any move or copy jobs) and
are processed one by one.
+ The new SVDRP command MOVR can be used to rename a recording
+ Note that in several places in the source code a "copy" operation is mentioned,
however there is no user interface for this, yet.
- The function cRecordings::MBperMinute() now only takes into account recordings with
less than 5 seconds per megabyte, in an attempt to filter out radio recordings
The result of this function was way off any realistic
value in case there are many radio recordings in the video directory.
- When cutting a recording it is now checked whether there is already an edited
version of this recording (with the same name, but starting with '%'), and the
user is prompted for confirmation to overwrite it.
- Fixed numbering frames. Previously they were numbered starting from 1, while it
is apparently standard to number them from 0. Any existing recordings with editing
marks (which will now be off by one) can still be cut with all VDR versions from
1.7.32, because these will automatically adjust editing marks to I-frames.
Users of stable releases shouldn't notice any problems.
- Now returning from removing deleted recordings after at most 10 seconds, or if the
user presses a remote control key, to keep the system from getting unresponsive
when removing a huge number of files.
- Fixed generating the index file of an existing recording in case at the end of a TS file
there is less data in the buffer than needed by the frame detector. In such a case
it was possible that frames were missed, and there was most likely a distortion
when replaying that part of a recording. This is mostly a problem for recordings that
consist of more than one *.ts file. Single file recordings could only lose some
frames at their very end, which probably doesn't matter. At any rate, if you have
generated an index file with VDR version 2.0.6, 2.1.5 or 2.1.6, you may want to
do so again with this version to make sure the index is OK.
- Added the new command line option --updindex, which can be used to update an
incomplete index of a recording.
- In the "Edit recording" menu the '0' key can now be used on the "Name:" field to
remove the name of the recording and replace it with the last element of the
recording's folder path name. See MANUAL, section "Managing folders" for details.
Replay:
- The new option "Setup/Replay/Pause replay when jumping to a mark" can be used to
turn off pausing replay when jumping to an editing mark with the '9' key.
- The new option "Setup/Replay/Skip edited parts" can be used to automatically skip
the edited parts of a recording during replay, without the need to actually cut
the recording.
- The new option "Setup/Replay/Pause replay at last mark" can be used to make replay
go into Pause mode when it has reached the last "end" mark.
- The '8' key for testing an edited sequence now also jumps to the next *end*
mark if "Setup/Replay/Skip edited parts" is active. This allows for testing edits
in recordings that have actually been cut, as well as recordings that have not
been cut, in case "Skip edited parts" is enabled.
- A recording is now still considered unviewed when stopping replay within 10 seconds
of the first mark.
- The keys '1' and '3' can now be used in replay mode to position an editing mark
in "adaptive" mode. See MANUAL, section "Editing a Recording".
- The new option "Setup/Replay/Alternate behavior for adaptive skipping" can be used
to make adaptive skipping only halve the skip distance when the direction changes.
That way you can reach the desired point in a recording even if you make one too
many skips in a certain direction (see MANUAL for details).
SVDRP:
- The new SVDRP command MOVR can be used to rename a recording
Audio:
- Added the new parameters "Setup/Miscellaneous/Volume steps" and
".../Volume linearize". See the MANUAL for details.
- Added handling for DTS audio tracks to cPatPmtParser::ParsePmt().
Misc:
- Reverted the change from version 1.5.7 that made all logging go to LOG_ERR.
- The Yellow button in the main menu no longer acts as "Pause" if "Pause key handling"
is set to "do not pause live video".
- Added code for parsing LCN and AVC descriptors to libsi.
- Changes in the teletext PID no longer cause retuning (and thus interrupting a
recording).
- Made it clear that the Data parameter in cDevice::StillPicture() may point to a
series of packets, not just a single one.
- Changed '%a' to the POSIX compliant '%m' in all scanf() calls.
- cTSBuffer now provides the number of available bytes in its Get() function.
- The script given to VDR with the '-r' option is now also called after the recording
process has actually started.
- Updated 'sources.conf'.
- Increased MIN_TS_PACKETS_FOR_FRAME_DETECTOR to 100 and introduced counting the number
of actual video TS packets in cTsPayload in order to be able to record channels that
sometimes need many TS packets for detecting frame borders.
- Improved PAT/PMT scanning to speed up initial tuning to encrypted channels on
transponders with many PAT entries.
- The SDT is now only parsed *after* the NIT has been read, and it explicitly uses
the source value derived from the NIT. This should prevent new channels from being
created with the wrong source.
- Added support for systemd. To activate this you need to add "SDNOTIFY=1" to the
'make' call.
- No longer logging an error message in DirSizeMB() if the given directory doesn't
exist. This avoids lots of log entries in case several VDRs use the same video
directory and one of them has already physically removed a recording directory,
while the others still have it in their list of deleted recordings.
- VDR now reads command line options from *.conf files in /etc/vdr/conf.d.
See vdr.1 and vdr.5 for details.
- Added the functions IndexOf(), InsertUnique(), AppendUnique() and RemoveElement()
to the cVector class.
- Added functions to set and retrieve the priority of a cReceiver.
- Changed the German weekday names from "MonDieMitDonFreSamSon" to
"Mo.Di.Mi.Do.Fr.Sa.So.".
- Added the channel name to log messages that reference a channel.
- Added ARGSDIR to the ONEDIR section of Make.config.template.
- Added SDNOTIFY, NO_KBD, BIDI and REMOTE to Make.config.template.
- Modified runvdr.template to improve compatibility with the "bash" and "dash" shells.
- Updated sources.conf to reflect the fact that Astra 4A and SES5 are actually in
two separate positions.
- Fixed cMarks::GetNextBegin() and cMarks::GetNextEnd(). The behavior of these two
functions is now exacly as described in the header file. Editing marks that are
placed at exactly the same offset in a recording are now preserved in the cutting
process.
