Hi Carel,
with nvdec and vdpau
how about cuvid?
And yes, it might be related, you never know. Please show debug log. What video sync mode do you use?
“play silence instead of dupping audio for all sync modes” is meant to improve the situation.
There are 2 reasons for playing silence.
Either you hear silence instead of cracking noise.
Or it is there instead of underrun, stop of audio and restart of audio and sync. Which would cause much more delay.
So I guess, that is what everybody wants.
If people prefer cracks and underruns instead of silence, I could make it configurable
But maybe there is a bug somewhere, I can't test every situation.
time-shift recording starts playing back
You start a recording, and then play it, while it's still recording or something else?
Best, Jörg
lip-sync delay
definitly shouldn't happen
Does it also happen with just playing back the recording without time-shift?
I have an idea for a fix. I will make a commit next week, when I am back home.
In playback the silence mechanism isn't needed cause al data are there already, so I will disable it for playback.
Ist gar nicht nötig, da bereits so eingebaut: Bei einer Aufnahme (IsReplay()) sind die Bedingungen in [1] und [2] nicht erfüllt. Und bei Beginn einer Aufnahme wird PlayRingbuffer wieder aktiviert [3].
Deswegen denke ich, es hat nichts mit meinen Änderungen zu tun.
Ein Debug-Log wäre trotzdem interessant.
after resume playback
You mean after pausing and resuming playback? That's new information.
Anyway I need a debug log.
What sync mode in softhddevice you use?
Are you using some timeshift plugin/patch? And if so, which one?
What does the patch permashift give?
And where to see it?
https://github.com/eikesauer/Permashift
Description:
Permashift saves the TV channel shown live into a ring buffer in RAM.
Thus VDR can rewind from live TV or prepend video from the past to
an instant recording....
I.e. in the original VDR the timeshift is saved to disk, and with the patch to memory, is this the main difference?
And with the plugin the timeshift is always on.
Yes that's about it! It's a gimmick 
Handy if you just missed the last goal in a soccer match that happened e.g. 10 min ago...
Just press rewind and wait until you see it,
I must say that after rewind and replay sometimes the audio/video is out of sync, but please don't bother.
This feature is not used frequently and the plugin and vdr patch are not very actively maintained.
Permashift gives the opportunity to rewind back in LiveTV! This is no timeshift, as timeshift is stored as as recording, this is just for the active channel in memory.
