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. |
