2008-09-06Version 1.7.1vdr-1.7.1Klaus Schmidinger
- Adapted the tuning code to the new DVBFE_SET_DELSYS API (thanks to Reinhard Nissl). VDR now uses the driver from http://jusst.de/hg/multiproto_plus. - Updated the Italian OSD texts (thanks to Diego Pierotto). - Removed obsolete $(NCURSESLIB) from the Makefile. - Implemented handling the standard component descriptor for AC3 (stream=4), as it will soon be used by the German ARD channels (thanks to Michael Pennewiß for advance information about this change). The previously used "Premiere pseudo standard" (stream=2, type=5) still works, but has apparently been wrongfully used by broadcasters from the beginning. - Added missing description of the 'S' channel parameter to vdr.5 (reported by Reinhard Nissl). - The SVDRP signon message now indicates the character encoding in use, as in "220 video SVDRP VideoDiskRecorder 1.7.1; Fri May 2 16:17:10 2008; ISO-8859-1". This may be useful for instance for external tools that provide EPG data, so that they can correctly encode the strings. - No longer calling FcFini() to avoid problems with older (broken) versions of fontconfig (suggested by Edgar Toernig). - Removed the compile time option VFAT to allow users of precompiled binary distributions to have full control over whether or not to use the --vfat option at runtime (suggested by Michael Nork). - First step towards switching to TS (Transport Stream) as recording format: + The new function cDevice::PlayTs() is used to play TS packets. + The new functions cDevice::PlayTsVideo() and cDevice::PlayTsAudio() are used to play video and audio TS packets, respectively. + The new function cAudio::PlayTs() is used to play audio TS packets. + The new class cPatPmtGenerator is used to generate a PAT/PMT pair that precedes the TS data in Transfer Mode. + The new class cPatPmtParser is used by cDevice to parse the PAT/PMT data in a TS in order to find out which streams it contains. + The new class cTsToPes is used to convert TS packets to a PES packet. + cTransfer no longer uses cRemux, and doesn't run a separate thread any more. It just generates a PAT/PMT and sends all received TS packets to the primary device's PlayTs(). + Live subtitle display no longer uses a ring buffer and separate thread. + cPesAssembler has been removed. Old VDR recordings only contain complete PES packets. + Since a TS needs to have a PAT/PMT, which requires the video stream type to be explicitly given, the format of the VPID field in the channels.conf file and the SVDRP commands NEWC/MODC/LSTC has been extended. The video stream type now follows the VPID and optional PPID, separated by an '=' sign. - Updated the sources.conf file (thanks to Oleg Roitburd). - Fixed a possible integer overflow in GetAbsTime() (thanks to Alexander Rieger). - Fixed a problem with calling isyslog() from within the SignalHandler() (thanks to Udo Richter). - Replaced the Finnish language code "smi" with "suo" (thanks to Rolf Ahrenberg). - Fixed wrong value for TableIdBAT in libsi/si.h (thanks to Winfried Köhler). - Errors in config files no longer keep VDR from starting. - Removed unneeded include files <linux/dvb/dmx.h> und <time.h> from remux.h (reported by Tobias Grimm).
2008-04-13Version 1.7.0vdr-1.7.0Klaus Schmidinger
- Re-implemented handling of DVB-S2, which first appeared in version 1.5.14, but was revoked in version 1.5.15 in favor of making a stable version 1.6.0. VDR now requires the "multiproto" DVB driver, e.g. from http://jusst.de/hg/multiproto. Note that the channels.conf file now supports additional parameters, so you may want to make sure you have a backup of this file in case you need to go back to the previous version of VDR! - Fixed displaying transponder data when it is modified (thanks to Reinhard Nissl). - Fixed handling the counter in detection of pre 1.3.19 PS data (thanks to Reinhard Nissl). - Improved logging system time changes to avoid problems on slow systems under heavy load (suggested by Helmut Auer). - Now setting the thread name, so that it can be seen in 'top -H' (thanks to Rolf Ahrenberg). - Fixed initializing the timer's flags in the cTimer copy constructor (thanks to Andreas Mair). - Fixed setting the OSD level in the 'osddemo' example (thanks to Wolfgang Rohdewald). - Increased the time between checking the CAM status to 500ms to avoid problems with some CAMs (reported by Arthur Konovalov).
2005-02-13Version 1.3.21vdr-1.3.21Klaus Schmidinger
- Fixed cDvbDevice::SetAudioTrackDevice() to avoid a blank screen after switching back to live mode if a recording is currently active on the primary device. - Fixed a possible freeze in pause mode in case a device's PlayPesPacket() function permanently returns 0 (thanks to Reinhard Nissl and Olaf Titz). - Completed the Finnish OSD texts (thanks to Rolf Ahrenberg). - Restricted the "setting audio track" log message to automatic changes during replay. - Fixed handling Transfer Mode for radio channels (thanks to Andreas Regel for reporting this one). - Fixed handling symbolic links in cRecordings::ScanVideoDir() (thanks to Stefan Huelswitt). - Completed the Danish OSD texts (thanks to Mogens Elneff). - Forcing a new resync after a call to cRemux::Clear() (suggested by Marco Schlüßler). - The cAudio::Play() function now has an additional parameter 'uchar Id' which tells the function the substream id of the given audio packet, so that a plugin can take the right action for the various kinds if audio data - which now also includes "normal" audio with ids 0xC0...0xDF (based on suggestions by Werner Fink and Macro Schlüßler). - Removed the "Cleared/PlayPes(NULL, 0)" handling from cTransfer::Action(), since this is now done when attaching the player to the device (thanks to Marco Schlüßler). - Making sure the buffer reserve in cTransfer::Action() is re-established after clearing the buffer. - Added DeviceClrAvailableTracks() and DeviceSetCurrentAudioTrack() to cPlayer (thanks to Marco Schlüßler). - Fixed a typo in detecting UTF-8 (thanks to Reinhard Nissl). - Now using twice the buffer reserve in cTransfer if the primary DVB card is an unmodified version with only 2MB of SDRAM, to avoid audio stuttering when playing Dolby Digital over the DVB card (thanks to Christian Jacobsen and Chad Flynt for suggestions and experiments in that area). - Making sure the first audio packet is not dropped when switching to "pre 1.3.19 Dolby Digital compatibility mode". - The 'plugins-clean' target of the Makefile now only deletes the actual plugin library files from this version of VDR (suggested by Andreas Brachold). - Added a missing 'resultSkipped = 0' to cRemux::Clear() (thanks to Marco Schlüßler for reporting this one). - The new function cDvbDevice::SetTransferModeForDolbyDigital() can be used by plugins that implement Dolby Digital output and thus want to prevent the cDvbDevice from starting Transfer Mode in order to replay DD over the DVB device. - Added missing reset of the 'repacker' to cTS2PES::Clear() (thanks to Marco Schlüßler for reporting this one).
2002-11-03Version 1.1.15vdr-1.1.15Klaus Schmidinger
- Completely switched to the new CVS HEAD version of the linux-dvb driver. The NEWSTRUCT compile time switch is now obsolete. The required driver is now the CVS HEAD version dated 2002-11-01 or later. - Adjusted the INSTALL file to the 1.1.x version. - Only accepting key presses from the current remote control when learning (thanks to Oliver Endriss). - Fixed the EPG scanner, which broke 'Transfer Mode' as soon as it kicked in (thanks to Oliver Endriss for reporting this one). - Fixed handling audio tracks in cDvbDevice. - Updated channels.conf.terr (thanks to Uwe Scheffler). - Fixed displaying the group separators in the channel display (thanks to Martin Hammerschmid for pointing out this one). - The Makefile now includes the file Make.config (if present in the VDR source directory), which allows the user to overwrite several settings with individual values (suggested by Andreas Schultz). The VDR distribution archive does not contain this file in order to not overwrite a user defined file. There is a Make.config.template which contains the default values of the macros the user can overwrite. - Since there have been changes to the 'newplugin' script authors of plugins may want to newly create their plugins' Makefiles with the new version of this script, and adapt them to their individual needs (make sure you don't overwrite your existing plugin directory - make a backup copy first!). - Fixed reading EPG data via the SVDRP command PUTE (it changed the current service ID). - Fixed closing all dup'ed file descriptors in cPipe. - Implemented a plugin interface for additional audio processing (see PLUGINS.html under "Dolby Digital"). The functionality of the '-a' command line option has been reactivated. Since the author doesn't have any Dolby Digital equipment this may or may not work as expected. There may still be some places where a call to cAudios::Clear() or cAudios::Mute() is necessary. Those with Dolby Digital equipment should please take a look at this and maybe send patches. Replaying Dolby Digital in ways other than through VDR's '-a' option will have to be implemented as plugins. Those who have written patches for VDR version 1.0.x should convert their work into the proper plugins for version 1.1.x. Note to authors of cPlayer derived plugins: please read the modified comments in device.h regarding the member functions cDevice::Clear(), cDevice::Mute() and cDevice::PlayAudio(). Derived classes must call these base class member functions to make sure all registered cAudio objects are properly handled. Also note that the return type of cDevice::PlayAudio() has been changed to 'void', since this function always has to accept the entire data block immediately and there is nothing that could be reasonably done in case an error occurs in one of the cAudio objects. - Now checking the driver's DVB_API_VERSION in dvbdevice.h. Since VDR now requires a driver dated 2002-11-01 or later the MIN_DVB_DRIVER_VERSION_FOR_TIMESHIFT and DVB_DRIVER_VERSION stuff has been replaced with DO_REC_AND_PLAY_ON_PRIMARY_DEVICE, which can be used to disable simultaneous recording and replaying on the primary DVB device in case there are problems with this.
2002-06-16Version 1.1.3vdr-1.1.3Klaus Schmidinger
- Improved the VDR Makefile to avoid a warning if the '.dependencies' file does not exist, and also using $(MAKE) to call recursive makes. - Changed the name of the 'package' target in the plugin Makefiles to 'dist' (following the suggestions in the "GNU Make" manual). If you already have started a plugin project, you may want to change this in your Makefile accordingly. - Improved the plugin Makefile to avoid a warning if the '.dependencies' file does not exist, and also using $(shell...) to get the version numbers. If you already have started a plugin project, you may want to change this in your Makefile accordingly. - Fixed some function headers to make them compile with gcc 3.x (thanks to Gregoire Favre). - Fixed the cutting mechanism to make it re-sync in case a frame is larger than the buffer (thanks to Sven Grothklags). - Added an error message if the directory specified in the '-L' option can't be accessed (suggested by Stefan Huelswitt). - Rearranged OSD class names to make 'cOsd' available for the main OSD interface. - Completely moved OSD handling out of the cDvbApi class, into the new cOsd. - Implemented cStatus to allow plugins to set up a status monitor. See PLUGINS.html for details. - Moved the cEITScanner out of dvbapi.h/.c, into the new eitscan.h/.c. - Added Swedish language texts (thanks to Tomas Prybil). - Fixed parsing 'E' records in epg2html.pl (thanks to Matthias Fechner for pointing out this one). - Removed compiler option '-m486' to make it work on non-Intel platforms. If you have already started a plugin project, you may want to make sure you remove this option from your existing Makefile. - Completely rearranged the recording and replay functions to make them available to plugins. - Replay is now done in a single thread (no more syncing between input and output thread necessary). - It is now possible to record several channels on the same transponder with "budget cards". VDR automatically attaches a recording timer to a card that already records on the appropriate transponder. How many parallel recordings can actually be done depends on the computer's performance. Currently any number of recordings gets attached to a card, so you should carefully plan your timers to not exceed the limit. On a K6-II/450 it was possible to record three channels from transponder 12480 with a single WinTV NOVA-S. - Timers that record two successive shows on the same channel may now overlap and will use the same DVB card. During the time where both timers record the data is simply saved to both files. - The following limitations apply to this version: + Transfer mode doesn't work yet. + The '-a' option (for Dolby Digital audio) doesn't work yet. + Switching between different language tracks doesn't work yet. + Cutting doesn't work yet.
