Skipping on UK recordings degraded in 211017

[gEd]

Will check tomorrow.chéers

But yes it works fine with the standard files from 17 Oct release except for the skipping problem

[mvallevand]

er...isn't that what the above screenshot shows?

Sorry I'm used to seeing the confusing American style and the 5th confused me because it is only the fourth here.

Or perhaps a bit of " he who goes forth with a fifth on the fourth may not come forth on the fifth".

I rolled back to a version from September and replayed the same video again. They key difference to note is that with the 17 oct version, it is launching 2 LAV audio decoders.
I thought that this was b/c the video has an additional audio channel (204) for the visually impaired. However I remuxed the recording and tried again (keeping file name the same) and it still starts 2 x LAV audio decoders.

I also note that the message "reference clock changed" only appears in the newer logs

I run npvrsetup again to upgrade from pre 17-oct version to latest build, added the 2 x dlls you asked me to test (to both folders) and it still barfs.

It probably worth posting a link to a 100MB sample of a problem file. Something large enough to skip in that you have the problem with there.

Martin

[gEd]

Here's a 100MB sample taken with cutchunk (from end of file)

https://drive.google.com/file/d/1UhwfrEG...sp=sharing

It's just standard UK Freeview HD (stream 0 H264 video, stream 1 audio, stream 2 audio for visually impaired, stream 3 DVB subtitles)

[mvallevand]

That file doesn't have very good timestamps, so it might not be the best test. I have 5.1.2 and 5.2.2 on my system, and neither skip very crisply but I found 5.1 seemed to have longer pauses after the skip. Same thing with V4 there are certainly pauses after the skip

Are you comparing NextPVR and Kodi perhaps?

As for lip sync typically talk shows work better but I found that when video did start after a skip lip sync was ok.

Martin

[gEd]

No, just the nextpvr client. I had been playing with kodi as an app on my TV to simply things (like only needing to use the TV remote) but had periodic black frames gave up on that for the moment and switched back to the native windows client so we could watch TV without issue. This was fine until the 17 oct update.

do you have thoughts on why the newer version starts up 2 x LAV audio filters , whether this is expected behaviour and why the behaviour might be different from the previous release?

[mvallevand]

If you check the status it is opening an aac decoder. There is a identified audio tream pid 204 that is missing in the mux. In theory NextPVR does need to add it in case the stream appears.

humm, having played around a bit more, I see that the pre-17 Oct version also goes into slow-mo for about 1.5 seconds after a skip but I'm pretty sure it's not as bad as the 17 oct release.. I need to investigate some more.

by way of comparison, this .ts file that I converted to a h265 files some time ago, skips absolutely perfectly.

That's not a particularly valid test, mp4 file are designed for seeking ts files are not. Much of the playback of mp4 files is out of NextPVR's control too.
