- 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).

- 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).
