- Fixed determining the frame duration on channels where the PTS deltas jitter by
+/-1 around 1800.
- The PCR pid in generated PMTs is now set to the channel's PCR pid again, which
in most cases is the same as the video pid. For channels that use a separate
PCR pid, no TS packets are recorded from that PID (I have yet to see a case where
this actually is a problem).
- The PCR pid in generated PMTs is now set to the channel's PCR pid again.
- Fixed determining the frame duration on channels where the PTS deltas jitter by
+/-1 around 3600.
- The PCR pid is now recorded for channels where this is different from the video
PID. To facilitate this, the interfaces of cTransfer, cTransferControl, cRecorder
and cReceiver have been modified, so that the PIDs are no longer given in separate
parameters, but rather the whole channel is handed down for processing. The old
constructor of cReceiver is still available, but it is recommended to plugin authors
that they switch to the new interface as soon as possible.
When replaying such a recording, the PCR packets are sent to PlayTsVideo()
