Hi,

on playback old HDTV recordings the timline is wrong.

From a first look it seems to show the double length

of the recording.

VDR developer version 1.7.3 is now available at

  ftp://ftp.cadsoft.de/vdr/Developer/vdr-1.7.3.tar.bz2

A 'diff' against the previous version is available at

  ftp://ftp.cadsoft.de/vdr/Developer/vdr-1.7.2-1.7.3.diff

WARNING:

This is a *developer* version. Not even *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 the switch to Transport Stream (TS) as the recording format. There are still a few glitches, mainly

• Recording/replaying of pure audio broadcasts doesn't work yet.
• Recording files larger than 4GB or with more than 255 separate files hasn't been tested yet.
• Recording h.264 broadcasts has been roughly verified to work, but no replaying of such recordings has been tested yet.
• There is apparently still a problem with editing old PES recordings. An edited recording is created, but it doesn't play.

DO NOT USE THIS VERSION FOR PRODUCTIVE RECORDINGS!! THE RECORDING OR OTHER FILE FORMATS MAY STILL CHANGE AND ANY RECORDINGS MADE WITH THIS VERSION MIGHT NOT WORK WITH FUTURE VERSIONS! Despite this, I do hope there will be some people who can take a look at the changes and maybe test the new recording format - and report bugs or provide fixes ,-)

The changes since version 1.7.2:

• Updated the Russian OSD texts (thanks to Oleg Roitburd).
• Fixed handling the 'pointer field' in generating and parsing PAT/PMT

(thanks to Frank Schmirler).

• Fixed handling modulation types for DVB-S transponders when processing

the NIT.

• Changed cDvbDevice::GrabImage() to use V4L2 (thanks to Marco Schlüßler).
• Added a poll to cDvbDevice::PlayVideo() and cDvbDevice::PlayAudio() to

avoid excessive CPU load (this is just a makeshift solution until the FF DVB cards can play TS directly).

• The recording format is now Transport Stream. Existing recordings in PES

format can still be replayed and edited, but new recordings are done in TS. All code for recording in PES has been removed. The following changes were made to switch to TS recording format:

• The index file format has been changed to support file sizes of up to

1TB (previously 2GB), and up to 65535 separate files per recording (previously 255).

• The recording file names are now of the form 00001.ts (previously

001.vdr).

• The frame rate is now detected by looking at two subsequent PTS

values. The "frame duration" (in multiples of 1/90000) is stored in the info.vdr file using the new tag F (thanks to Artur Skawina for helping to get the IndexToHMSF() calculation right).

• Several functions now have an additional parameter FramesPerSecond.
• Several functions now have an additional parameter IsPesRecording.
• The functionality of cFileWriter was moved into cRecorder, and cRemux

is now obsolete. This also avoids one level of data copying while recording.

• cRemux, cRingBufferLinearPes, cTS2PES and all c*Repacker classes have

been removed.

• A PAT/PMT is inserted before every independent frame, so that no extra measures need to be taken when editing a recording.
• The directory name for a recording has been changed from YYYY-MM-DD-hh[.:]mm.pr.lt.rec (pr=priority, lt=lifetime) to YYYY-MM-DD-hh.mm.ch-ri.rec (ch=channel, ri=resumeId). Priority and Lifetime are now stored in the info.vdr file with the new tags P and L (if no such file exists, the maximum values are assumed

by default, which avoids inadvertently deleting a recording if disk space is low). No longer storing Priority and Lifetime in the directory name avoids starting a new recording if one of these is changed in the timer and the recording is re-started for some reason. Instead of Priority and Lifetime, the directory name now contains the channel number from which the recording was made, and the "resume id" of this instance of VDR. This avoids problems if several VDR instances record the same show on different channels, or even on the same channel. The '-' between channel number and resumeId prevents older versions of VDR from "seeing" these recordings, which makes sure they won't even try to replay them, or remove them in case the disk runs full.

• The semantics of PlayTs*() have been changed. These functions are now required to return the given Length (which is TS_SIZE) if they have processed the TS packet.
• The files "index", "info", "marks" and "resume" within a TS recording directory are now created without the ".vdr" extension.
• The "resume" file is no longer a binary file, but contains tagged

lines to be able to store additional information, like the selected audio or subtitle track.

• cDevice::StillPicture() will now be called with either TS or PES data.
• cDvbPlayer::Goto() no longer appends a "sequence end code" to the

data. If the output device needs this, it has to take care of it by itself.

• Fixed cPatPmtParser::ParsePmt() to reset vpid and vtype when switching

from a video to an audio channel (thanks to Reinhard Nissl).

• cDvbDevice now uses the FE_CAN_2G_MODULATION flag to determine whether a

device can handle DVB-S2. The #define is still there to allow people with older drivers who don't need DVB-S2 to use this version without pathcing.

Have fun!
