- Fixed setting the audio language codes in 'Transfer-Mode' (reported by Rolf Ahrenberg). The actual problem was the call to the Transferring() function in cDevice::AttachPlayer() before assigning the player. - Fixed removing the '-' when entering a channel number where there is no other one that fits the input (thanks to Joachim Wilke). - Fixed the 'libsi' function CharArray::checkSize(), which made a previous workaround in libsi/descriptor.c obsolete (thanks to Marcel Wiesweg). - The "Ok" key in the "Jump" mode of the replay progress display now confirms the jump instead of closing the display (thanks to Christoph Haubrich). - The 'summary' field of a timer definition has been renamed to 'aux', and is now only used for external applications to store auxiliary information with a timer, which has no meaning whatsoever to VDR itself. The contents of the 'aux' field of a timer is copied into the recording's 'info.vdr' file, using the tag character '@'. - The description of a recording is now taken exclusively from its related EPG data. If an application wants to use a different description it needs to set it with SVDRP/PUTE and use table ID 0x00, so that it won't be overwritten (as a side effect, however, this also disables VPS for such an event). - There is no more "Summary" menu when pressing "Ok" in the "Timers" menu. The "Ok" key now always opens the "Edit timer" menu. - The upper 16 bit of a timer's "flags" are no longer treated specially when a timer is modified in the "Edit timer" menu. If an external application needs to know if a timer was modified, it has to keep a copy of the timer's data and compare that to the actual data. - The new function cRecordingInfo::ChannelID() can be used to retrieve the ID of the channel a recording was made from. - The 'info.vdr' file of a recording now also contains the 'E' and 'V' records of the EPG event used when creating it. - The option "Setup/OSD/Sort timers" has been removed. Timers are always sorted by their start time and priority. - The "Blue" key in the "Timers" menu now displays the EPG info of the event the selected timer will record (if available). The "On/Off" function has been shifted to the "Red" button. Editing a timer is done by pressing "Ok". - When determining which event a timer is going to record, all available events in the future are now taken into account (no more limit to 4 hours in the future). This has been done so that the event info is available in the "Timers" menu when pressing the "Blue" button. In order to avoid unnecessary work, each timer now has its own timestamp to control whether its schedule has changed since the last time its event has been set. - Fixed setting events to timers in case a non-VPS event has expired. - There is now a log message "timer ... set to event ..." when defining a timer from the EPG menu. - Lines tagged with '#' in the 'info.vdr' file of a recording are now silently ignored when reading that file (suggested by Peter Bieringer). Such lines can be used by external tools to store arbitrary information. - The 'event id' in EPG data has been extended to 32 bit, so that external tools can generate ids that don't collide with those from the DVB data stream (suggested by Matthias Schniedermeyer). - The DrawBitmap() function now has a new parameter 'Overlay' that allows a bitmap to be drawn with a transparent background (thanks to Alexander Hans). - Fixed cSchedule::GetFollowingEvent() in case there is currently no present event running (thanks to Pekka Mauno).
2006-02-19Version 1.3.43vdr-1.3.43Klaus Schmidinger
- Removed an unnecessary toFile->SetReadAhead() from cutter.c (thanks to Artur Skawina). - The "Back" key now restores the original string when pressed while editing a string item (suggested by Markus Hahn). - Now stopping scanning the video directory if there are too many levels of symbolic links, which might indicate a recursive link loop (based on a patch from Helmut Auer). - Improved OSD area handling in cDvbSpuDecoder (thanks to Marco Schlüßler). - Now logging the description (if present) in case a thread is canceled (suggested by Marco Schlüßler). - cMenuText now uses the given font (thanks to Rolf Ahrenberg). - The ST:TNG skin now uses the fixed font if requested when displaying texts. - Fixed some typos in the CONTRIBUTORS file (thanks to Frank Krömmelbein). - Changed offset and size handling in 'libsi' from 'unsigned' to 'signed', so that overflows can be better detected (thanks to Marcel Wiesweg). - Checking data size in CaDescriptor::Parse() and LinkageDescriptor::Parse() of 'libsi' to avoid crashes with invalid data (thanks to Marcel Wiesweg). - Made CharArray::DataOwnData::assign() in 'libsi' more robust against invalid data (suggested by Oliver Endriss). Also changed CharArray::DataOwnData::Delete() so that it sets 'size' and 'data' to 0. - Now resetting the channel number if the number entered through the numeric keys exceeds the maximum channel number (thanks to Rolf Ahrenberg). - The language code in the 'X' component records of EPG data can now consist of two codes, separated by '+'. - If a recording starts and there is no EPG data available for the recorded channel, the 'X' audio component records for the 'info.vdr' file are now generated from the channel's PID data. - Externally provided EPG data (with table ID 0x00) now gets its component descriptors set from the broadcast data, so that language codes and descriptions are available (suggested by Andreas Brugger). - When setting the audio track descriptions, the language codes are now also set in case this is a replay session (based on a patch from Rolf Ahrenberg). - If a recording starts and the channel's audio PID data has more language code information than the EPG's component data, the code from the channel is taken. - Fixed handling DPID when deciding whether to switch to 'Transfer Mode' (thanks to Marco Schlüßler). - Fixed replaying recordings of radio channels with many audio tracks (thanks to Reinhard Nissl). - Added a comment to tChannelID::nid, explaining that is is actually the "original" network id.
2004-10-24Version 1.3.14vdr-1.3.14Klaus Schmidinger
- Fixed detecting transponder lock in cDvbTuner (based on a patch from Stefan Meyknecht). - What was previously marked with WAIT_FOR_LOCK_AFTER_TUNING is now permanently active and uses a cCondVar to signal when a transponder is locked. - Added some missing 'const' to cChannel. - Added a sample setup for 'DisiCon-4 Single Cable Network' to 'diseqc.conf' (thanks to Oliver Endriss). - Fixed attaching a cPlayer to a cDevice, so that 'Operation not permitted' errors don't occur any more (thanks to Marco Schlüßler). - Fixed a case where the resultBuffer in cRemux ran full before getting a sync. - Removed the usleep() call from cDvbPlayer::Action() to make VDR run on NPTL systems (thanks to Alfred Zastrow). The NPTL check at startup has also been removed. - Taking the complete size of available data into account when deciding whether to clear the transfer buffer to avoid overflows (thanks to Reinhard Nissl). - Updated Romanian language texts and the iso8859-2 fonts (thanks to Lucian Muresan). - Now actually using the iso8859-15 fonts (thanks to Lucian Muresan). - Some minor code cleanups (thanks to Prakash K. Cheemplavam). - Fixed missing cleanup at program exit in case there is a problem with a plugin (thanks to Mattias Grönlund for pointing this out). - Increased the required free buffer space in the resultBuffer of cRemux to 2 * IPACKS to avoid a buffer overflow in case a cTS2PES writes one complete packet and then (within processing the same TS packet) wants to write another small packet. - Removed the signal handler and WakeUp() call from cThread (it is no longer needed). - Added some checks when canceling a thread and removed the usleep() in cThread::Start() (suggested by Ludwig Nussel). Also removed 'running' from cThread and using only childTid to indicate whether a thread is actually running. - Added cCondWait::Sleep() and using it to replace all usleep() calls (based on a suggestion by Werner Fink). - Only assigning events to timers if the related schedule has actually been modified. - When searching for the present event, the running status is now only taken into account if the event has been "seen" within the past 30 seconds. This avoids shortly seeing the wrong events in the channel display when switching to a channel that hasn't been tuned to in a while.
2004-10-17Version 1.3.13vdr-1.3.13Klaus Schmidinger
- 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).
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).
