VDR developer version 1.7.5 is now available at


A 'diff' against the previous version is available at



This is a *developer* version. Even though *I* use it in my productive
environment. I strongly recommend that you only use it under controlled
conditions and for testing and debugging.

The main focus of this version is still the switch to Transport Stream (TS)
as the recording format, as well as improved synchronization of replay
with the progress display, trick modes and subtitles.


You need the DVB driver version from


or, alternatively, apply the two patches


(in *this* sequence) in order to replay TS recordings with full featured
DVB cards! The second patch is only required for replaying pure audio
Users of full featured DVB cards also need to use a new firmware,
available at


Note that the header files in the latest driver versions may be broken.
If you get compiler error messages like

  /usr/include/sys/types.h:52: error: conflicting declaration 'typedef __ino64_t ino_t'
  /usr/include/linux/types.h:14: error: 'ino_t' has a previous declaration as 'typedef __kernel_ino_t ino_t'

when compiling VDR, you need to put the driver header files back to
how they were before they got broken. One way of doing this is to
apply the patch from


(I'm not claiming that this is the right way to fix this, since the driver
developers may have had good reasons for making that change. However, both
the driver and VDR compile and work fine with this).

The changes since version 1.7.4:

- Fixed a hangup when replaying a TS recording with subtitles activated (reported
  by Timo Helkio).
- Fixed handling the 'new' indicator in the recordings menu for TS recordings
  (thanks to Derek Kelly).
- Added cap_sys_nice to the capabilities that are not dropped (thanks to Rolf
- Updated the Italian OSD texts (thanks to Diego Pierotto).
- Added cRecordingInfo::GetEvent() (thanks to Marcel Unbehaun).
- Improved synchronizing the progress display, trick modes and subtitle display
  to the actual audio/video. This now works independent of any buffer sizes the
  output device might use.
  + The cBackTrace class has been replaced with cPtsIndex, which keeps track
    of the PTS timestamps of recently played frames.
  + cDevice::GetSTC() is now required to deliver the STC even in trick modes.
    It is sufficient if it returns the PTS of the most recently presented
    audio/video frame.
  + The full-featured DVB cards need an improved firmware in order to return
    proper STC values in trick modes (thanks to Oliver Endriss for enhancing the
    av7110 firmware).
- Adapted cFrameDetector::Analyze() to HD NTSC broadcasts that split frames over
  several payload units (thanks to Derek Kelly for reporting this and helping in
- Modified cFrameDetector::Analyze() to make it process whole frames at once, so
  that file I/O overhead is minimized during recording (reported by Günter
- Added command line help for the '-i' option.
- Fixed cDvbPlayer::NextFile() to handle files larger than 2GB (thanks to Jose
  Alberto Reguero).
- Improved replay at the begin and end of a recording. The very first and very last
  frame is now sent to the output device repeatedly until GetSTC() reports that it
  has been played. cDvbPlayer::Action() no longer calls DeviceFlush() (thanks to
  Reinhard Nissl for making sure vdr-xine no longer needs this).
- Added missing '[]' to the delete operator in cMenuEditStrItem::~cMenuEditStrItem().
- Added missing virtual destructor to cPalette.
- Now freeing configDirectory before setting it to a new value in
- Fixed a crash when jumping to an editing mark in an audio recording.
- Fixed the 'VideoOnly' condition in the PlayPes() and PlayTs() calls in
  cDvbPlayer::Action() (thanks to Reinhard Nissl).
- cDevice::PlayTs() now plays as many TS packets as possible in one call.
- Making sure any floating point numbers written use a decimal point (thanks to
  Oliver Endriss for pointing out a problem with the F record in the info file of
  a recording).
- Fixed detecting the frame rate for radio recordings.
- Added missing AUDIO_PAUSE/AUDIO_CONTINUE calls to cDvbDevice (thanks to Oliver
- No longer writing the video type into channels.conf if VPID is 0 (thanks to
  Oliver Endriss for reporting this).
- Improved efficiency of cEIT::cEIT() (thanks to Tobias Bratfisch).

Have fun!
