- Fixed checking for the presence of NPTL (thanks to Jouni Karvo). - Making sure section filters are only set if the device actually has a lock (thanks to Andreas Share for pointing this out). - Fixed a possible NULL pointer assignment in cMenuText::SetText() (thanks to Marco Schlüssler). - Fixed a crash in case the last line in channels.conf is a group separator and that group is selected in the channel display (thanks to Dick Streefland). - Added cRingBufferLinear::Read() to read directly from a file handle into the ring buffer. - Using timeouts in ring buffers to avoid 'usleep()'. - Clearing the 'Transfer Mode' ring buffer after clearing the device to avoid an "almost full" ring buffer. - Removed locking from cRingBufferLinear for better performance under high load. - Using a cRingBufferLinear in cRemux to avoid unnecessary copying of data. - Using a cRingBufferLinear in cTSBuffer and filling it in a separate thread to avoid buffer overflows. Plugins using cTSBuffer will need to remove the call to the now obsolete Read() function (see cDvbDevice::GetTSPacket() for the new usage of cTSBuffer). - cRemux::Process() has been split into Put(), Get() and Del() to allow for a better decoupling of the remuxing and disk writing process. Plugins using cRemux will need to be modified accordingly. - The actual disk writing in recordings is now done in a separate thread to improve the overall throughput. - Changed cRemux so that it returns the maximum available amount of data with each call, not just 2048 byte. - Added a visual display of all cRingBufferLinear buffers for debugging. To activate it, define DEBUGRINGBUFFERS in ringbuffer.h. - Instead of cCondVar now using the new cCondWait (which also avoids a possible "near miss" condition; thanks to Sascha Volkenandt for pointing out this one). cCondVar is still present for plugins that use it (and VDR itself also still uses it in cRemote). - The cRingBuffer now does EnableGet()/EnablePut() only if the buffer is more than one third full or empty, respectively. This dramatically improves recording performance and reduces system load (thanks to Marco Schlüßler for doing some testing regarding buffer performance and giving me some hints that finally led to finding out that this was the basic problem causing buffer overflows). - Improved Transfer Mode (thanks to Marco Schlüßler for suggestions and testing). - Fixed a possible crash with inconsistent SI data (thanks to Marcel Wiesweg). - Fixed showing the replay mode if the OSD is currently in use (thanks to Kimmo Tykkala for pointing out this problem). - cOsdProvider::NewOsd() now always returns a valid pointer, even if the OSD is currently in use (it will then return a dummy cOsd object and write a message to the log file). - Added Estonian language texts (thanks to Arthur Konovalov). - Fixed 'newplugin' and libsi/Makefile to use the compiler defined in $(CXX) for generating file dependencies (thanks to Andreas Brachold). - Moved the initialization of aPid1 and aPid2 to the beginning of cDvbDevice::cDvbDevice() to have them set in case a patch references them (thanks to Wayne Keer for pointing this out). - Completed the Russian OSD texts (thanks to Vyacheslav Dikonov). - Avoiding unnecessary section filter start/stops (thanks to Marco Schlüßler). - Made the "Channel not available!" message and mtInfo instead of mtError (suggested by Wayne Keer). - Made volume control more linear (thanks to Emil Naepflein and Udo Richter). - Now skipping code table info in SI data (suggested by Milos Kapoun). - Added missing Czech characters to fontosd-iso8859-2.c (thanks to Milos Kapoun). - Fixed a crash in the time search mechanism (reported by Reinhard Nissl). - If one PID can't be added, the whole cDevice::AttachReceiver() will now fail and all PIDs added so far will be deleted (thanks to Marco Schlüßler for pointing out this one). - Now only saving channels.conf after a modification made by the user (avoids lots of disk access due to automatic channel updates). Automatic channel modifications will be saved every 10 minutes if no recording is currently active. - Removed the 'Log' parameter from the cChannel::Set... functions. Instead checking if the channel has a non-zero number. - Updated 'channels.conf.terr' for Hannover (thanks to Sven Kreiensen).

- Fixed some default parameters in 'skincurses'. - Fixed cBitmap::DrawPixel(), which messed with other bitmaps' palettes in case the pixel coordinates were outside this bitmap (thanks to Sascha Volkenandt for reporting this one). - The cBitmap::DrawText() function now doesn't set any background pixels if the given background color is clrTransparent. This allows drawing "transparent" texts (suggested by Sascha Volkenandt). - The cBitmap::SetXpm() function now ignores unused "none" color entries, which some broken graphics tools write into XPM files (suggested by Sascha Volkenandt). - No longer setting lnb voltage if the frontend is not DVB-S (thanks to Marco Schlüßler). - Fixed displaying the current channel when switching via the SVDRP command CHAN (thanks to Jürgen Schmitz for reporting this one). - Fixed missing audio after replaying a DVD (thanks to Marco Schlüßler). - Added a note about the default assignment of the color keys to MANUAL. - Added a note about NPTL ("Native Posix Thread Library") to the INSTALL file (apparently the "fix" in version 1.3.0 didn't really fix this). - Modified 'libsi' to require callers to state the buffer sizes when getting strings in order to avoid buffer overflows (thanks to Philip Lawatsch for debugging a buffer overflow in eit.c).
2004-03-14Version 1.3.6vdr-1.3.6Klaus Schmidinger
- Completed the Finnish OSD texts (thanks to Rolf Ahrenberg). - Fixed some descriptor handling in 'libsi' (thanks to Stéphane Esté-Gracias). - Fixed handling the current menu item (thanks to Marc Hoppe). - Fixed assigning events to timers (they no longer get "stuck"). - Added log entries whenever the running status of an event changes (currently only logging the first 30 channels). - Fixed handling timers in VPS margin if the EPG scan is turned on (the EPG scan switched the device away from the channel, so it wouldn't see the change of the running status). - Fixed handling "itemized" texts in EPG data (thanks to Stéphane Esté-Gracias for pointing out this problem, and Marcel Wiesweg for improving 'libsi'). - Fixed handling VPS times at year boundaries. - Avoiding too many consecutive "ring buffer overflow" messages (which only slowed down performance even more). - Taking the Sid into account when detecting version changes in processing the PMT (thanks to Stéphane Esté-Gracias for pointing out this problem). - Completed the Russian OSD texts (thanks to Vyacheslav Dikonov). - Any newline characters in the 'description' of EPG events are now preserved to allow texts to be displayed the way the tv stations have formatted them. This was also necessary to better display itemized texts. - Fixed detecting the running status in case an empty EPG event is broadcast (thanks to Michael Pennewiß for pointing this out). - Improved performance when paging through very long menu lists. - Removed cSchedule::GetEventNumber() and cSchedule::NumEvents(). There is now cSchedule::Events() that returns the list of events directly. - Avoiding occasional bad responsiveness to user interaction caused by assigning events to timers. - Now explicitly turning on the LNB power at startup, because newer drivers don't do this any more (thanks to Oliver Endriss for pointing this out).
2004-02-29Version 1.3.5vdr-1.3.5Klaus Schmidinger
- Fixed reading the EPG preferred language parameter from 'setup.conf'. - Fixed switching to a visible programme in case the current channel has neither a video nor an audio PID. - Fixed editing channels (SID now range checked) and creating new channels (NID, TID and RID are now set to 0). - Fixed transponder handling to make it work with satellites that provide two transponders on the same frequency, with different polarization, like Hispasat at S30.0W (thanks to Thomas Bergwinkl for pointing this out). See man vdr(5) for details about the enhanced channel ID format. - Since there appears to be no general solution for the UPT error yet, a recording now initiates an "emergency exit" if the number of UPT errors during one recording exceeds 10 (suggested by Gregoire Favre). Since the UPT error doesn't happen on my system, this has not been explicitly tested. The "preliminary fix" for the UPT error in VDR/dvbdevice.c has been disabled by default, since it makes channel switching unpleasently slow. If you want to have that workaround back, you can uncomment the line //#define WAIT_FOR_LOCK_AFTER_TUNING 1 in VDR/dvbdevice.c. - Adapted the 'sky' plugin to use the actual channel IDs, and to fetch EPG data from www.bleb.org. - Limited automatic retuning to devices that actually provide the transponder (necessary for the 'sky' plugin). - Fixed handling receivers in the 'sky' plugin, so that a recording on the same channel won't interrupt an ongoing Transfer Mode. - Added subtable ID and TSDT handling to 'libsi' (thanks to Marcel Wiesweg). - Fixed some Russian OSD texts (thanks to Vyacheslav Dikonov). - Added the 'running status' to the EPG events. This is necessary for implementing the VPS function for recording. - Removed the obsolete 'present' and 'following' handling from the EPG data. - The EPG data is now always kept sorted chronologically in the internal data structures. This also means that any EPG data retrieved through the SVRDP command LSTE is guaranteed to be sorted by start time. - Now using the 'running status' in the channel display, so that a programme that has an end time that is before the current time, but is still running, will still be shown in the display (provided the broadcasters handle the 'running status' flag correctly). This also applies to programmes that have a start time that is in the future, but are already running. - Implemented an "EPG linger time", which can be set to have older EPG information still displayed in the "Schedule" menu (thanks to Jaakko Hyvätti). - Added PDCDescriptor handling to 'libsi'. - Implemented handling the VPS timestamps (aka "Programme Identification Label") for full VPS support for timers (provided the tv stations actually broadcast this information). The VPS time is displayed in the event info page if it exists and is different than the event's start time. - Extended the SVDRP command LSTE to allow limiting the listed data to a given channel, the present or following events, or events at a given time (thanks to Thomas Heiligenmann). - Fixed a typo in libsi/si.h (thanks to Stéphane Esté-Gracias). - Timers can now be set to use the VPS information to control recording a programme. The new setup options "Recording/Use VPS" and "Recording/VPS margin", as well as the "VPS" option in the individual timers, can be used to control this feature (see MANUAL for details). Note that this feature will certainly need a lot of testing before it can be called "safe"! - The "Schedule" and "What's on now/next?" menus now have an additional column which displays information on whether there is a timer defined for an event, whether an event has a VPS time that's different than its start time, and whether an event is currently running (see MANUAL under "The "Schedule" Menu" for details).
2004-01-18Version 1.3.2vdr-1.3.2Klaus Schmidinger
- Fixed resetting the EPG data versions after changing the preferred languages (thanks to Teemu Rantanen for reporting this one and helping to debug it). - Added LinkageDescriptor handling to 'libsi' (thanks to Marcel Wiesweg). - Added Russian language texts (thanks to Vyacheslav Dikonov). Plugin authors may want to add the new entries to their I18N texts and contact the translators to have their texts translated. Note that there are now 17 different OSD languages, so please make sure you have 17 versions for each of your texts. - Some corrections and additions to the Finnish OSD texts (thanks to Rolf Ahrenberg and Niko Tarnanen). - Fixed a wrong 'delta' value in the call to the shutdown script (thanks to Stephan Epstein for reporting this one). - Activated detection of radio channels (to avoid reports about "channels not being detected that used to be detected with the 'scan' utility or the original 'autopid' patch ;-). - Channels with a zero VPID no longer write a PPID into channels.conf. - Short channel names are now only stored if they actually differ from the full name. - The EPG scan now scans newly found transponders together with already existing ones. - The "Red" button in the "Setup/EPG" menu can now be used to force an EPG scan on a single DVB card system (see MANUAL for details). - The new SVDRP command 'SCAN' can be used to force an EPG scan on a single DVB card system (see MANUAL under Setup/EPG for details). - Fixed handling PID changes in 'Transfer Mode'. - Excess blanks in channel names read from the SDT are now removed. - Fixed wrong parameter settings when scanning NITs for terrestrial transponders (thanks to Christian Tramnitz for pointing out this one). - Fixed some out of bounds parameter settings when scanning NITs for cable and satellite transponders. - Added 'libsi' include files to the 'include' directory, so that plugins can use them (thanks to Marcel Wiesweg). - Now only processing NITs that contain the transponder they are actually broadcast on. - Fixed setting the source type for newly detected terrestrial transponders (thanks to Christian Tramnitz for his support in debugging this).
2004-01-11Version 1.3.1vdr-1.3.1Klaus Schmidinger
- Fixed a lockup in the EPG scanner when no non-primary device was available (thanks to Martin Holst for reporting this one). - Fixed a compiler warning about virtual cConfig::Load() functions (thanks to Lauri Tischler for reporting this one). - Fixed a warning about character comparison in libsi/si.c (thanks to Lauri Tischler for reporting this one). - The new parameter "Update channels" in the "Setup/DVB" menu can be used to control if and how channels will be automatically updated (see MANUAL). This has already been part of the 'autopid' patch by Andreas Schultz and has now been adopted. - Fixed a crash in case there is no DVB hardware present (thanks to Sascha Volkenandt for reporting this one). - Changed calculation of channel ids to make it work for tv stations that use the undefined NID value 0 (thanks to Teemu Rantanen for reporting this one). - Enhanced the SDT filter to handle multi part sections. - Added support for selecting preferred EPG languages (based upon a patch by Teemu Rantanen). - Fixed a 'const' in libsi/si.h (thanks to Marcel Wiesweg). - Fixed the 'su' call in 'runvdr' to make it work on systems that require the user name to appear before the command option (thanks to Robert Huitl). - Fixed testing for matching section filters in case they are turned off (thanks to Marcel Wiesweg). - In case of incomplete sections an error message is now logged only every 10 seconds. - Fixed a possible NULL pointer access in cEITScanner::Process() (thanks to Andreas Kool). - The actual transponder data is now taken from the NIT and existing channels are adjusted if necessary. If the NIT contains new transponders, they are scanned for channels during the next EPG scan. Note that only the satellite branches are tested, cable and terrestrial need to be tested by somebody who actually has such equipment.
2004-01-04Version 1.3.0vdr-1.3.0Klaus Schmidinger
- Changed thread handling to make it work with NPTL ("Native Posix Thread Library"). Thanks to Jon Burgess, Andreas Schultz, Werner Fink and Stefan Huelswitt. - The cThread class now accepts a 'Description' parameter, which is used to log the beginning and end of the thread, together with its process and thread id. For descriptions that need additional parameters you can use the function cThread::SetDescription(), which accepts 'printf()' like arguments. Existing plugins that use threads should be changed to use this functionality instead of explicit 'dsyslog()' calls inside their Action() function in order to support logging the thread ids. - Added "Slovak Link" and "Czech Link" to 'ca.conf' (thanks to Emil Petersky). However, 'ca.conf' is now pretty much obsolete due to the automatic CA handling. - Mutexes are now created with PTHREAD_MUTEX_ERRORCHECK_NP, which makes the 'lockingTid' stuff obsolete (thanks to Stefan Huelswitt). - Changed font handling to allow language specific character sets. - Adopted the small font character set from the "Elchi" patch (originally provided by Alessio Sangalli). - Greek language texts now use iso8859-7 character set (thanks to Dimitrios Dimitrakos). - Rearranged section data handling, so that the actual data handling can be done separately, even from within plugins. - The EPG data structures have been moved from eit.[hc] to epg.[hc] and have been adapted to the general VDR coding style. Plugins that use these data structures may need to change some function names (which should be obvious). The name 'subtitle' has been changed to 'shortText' to avoid clashes with actual subtitles that are part of a movie. The name 'extendedDescription' has been shortened to 'description'. - Replaced 'libdtv' with 'libsi' (thanks to Marcel Wiesweg), which is thread safe and can be used by multiple section filters simultaneously. - Added 'cRwLock' to 'thread.[hc]'. Note that all plugin Makefiles need to define _GNU_SOURCE for this to work (see the example plugin Makefiles and 'newplugin'). - Fixed a problem with crc32 in SI handling on 64bit systems (thanks to Pedro Miguel Sequeira de Justo Teixeira for reporting this one). - Fixed an alignment problem in CAM access on 64bit systems (thanks to Pedro Miguel Sequeira de Justo Teixeira for reporting this one). - Added 'StreamType' setting to CAM communication, which is important for Aston/SECA CAMs (thanks to Antonino Sergi). - Now the CA descriptors are sent to the CAM in the 'program' or 'ES level' sections, depending on where they are found in the PMT (thanks to Hans-Peter Raschke for reporting this one). This should make SkyCrypt CAMs work. - Now using the 'version number' of EPG events to avoid unnecessary work. - Channel data is now automatically derived from the DVB data stream (inspired by the 'autopid' patch from Andreas Schultz). - The current channel is now automatically re-tuned if the PIDs or other settings change. If a recording is going on on a channel that has a change in its settings, the recording will be stopped and immediately restarted to use the new channel settings. - EPG events now use the complete channel ID with NID, TID and SID. - Channel names in 'channels.conf' can now have a short form, as provided by some tv stations (see man vdr(5)). Currently channels that provide short names in addition to long ones are listed in the OSD as "short,long name", as in "RTL,RTL Television". The short names will be used explicitly later. - The Ca parameter in 'channels.conf' has been extended and now contains all the CA system ids for the given channel. When switching to a channel VDR now tests for a device that provides one of these CA system ids. The devices automatically get their supported ids from the CI handler. - The values in 'ca.conf' are currently without any real meaning. Whether or not a channel with conditional access can be received is now determined automatically by evaluating its CA descriptors and comparing them to the CA system ids provided by the installed CAM. Only the special values 1-16 are used to assign a channel to a particular device. - Increased the maximum number of possible OSD colors to 256. - Limited the line length in the EPG bugfix report, which appears to fix a buffer overflow that caused a crash when cleaning up the EPG data (at 05:00 in the morning).
