Version 1.7.1vdr-1.7.1
- 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).
