RE: a/v desynchronization - Peter82kr - 09.12.2017

this is sample of video i used avidemux to cut sample.

RE: a/v desynchronization - Selur - 09.12.2017

Before I look at it: Can you reproduce the problem with the sample?
-> can reproduce the problem with the sample, going to bed now, but will look at it tomorrow

Quick look with mediaInfo shows:

Format                                   : xvid
Commercial name                          : xvid
Codec ID                                 : xvid
Codec                                    : xvid
Codec                                    : xvid
Codec/CC                                 : xvid

-> Whoever created that file either did know what he was doing or doesn't care about standards at all.

Sample after conversion in hybrid is desynced but less than original file i think.But you can reproduce problem because is out of sync.

RE: a/v desynchronization - Selur - 09.12.2017

Send you a link to a version that should fix the remuxing problem and to avoid the reencoding problem enable 'Config->Internals->Avisynth->Always use Avisynth', this way Hybrid doesn't use mencoder as decoder and feeds mencoder with an Avisynth script.
-> At least for the sample that fixed the problem for me.

This log is only intended for user information.
It should not be part of a bug/problem report!!
Detected NVIDIA PureVideo compatible cards: GeForce GTX 1060
No sox binary found -> disabling audio support,...
removing support for ogg encoding
removing support for dts encoding
removing support for opus encoding
tsMuxer can't be used -> disabling 'generate structure'
Finished initialization, finished after 32.741s
tsMuxer can't be used -> disabling 'generate structure'

its added because its happend before i can enable debug output.

on start i have info that AVSMeter.exe doesnt exists.
I dont have audio tab in that test version.

EDIT:
I tried always use avisynth with no success with latest stable version.Still desync.

RE: a/v desynchronization - Selur - 09.12.2017

You did extract the dev version into your Hybrid folder right?

Cu Selur

RE: a/v desynchronization - Peter82kr - 09.12.2017

I extracted on desktop and run now i know how to do it properly.

EDIT: I cant access 10 bit encoding in test version even if i set h265.

EDIT2: A/V is still desynced when im using "always use avisynth" option in test version. Sad

The dev version comes with an updates NVEncC version so you might have to update your drivers.

Strange, will look at it again.

RE: a/v desynchronization - Peter82kr - 09.12.2017

I have latest nvidia drivers for my gtx 1060.

RE: a/v desynchronization - Selur - 09.12.2017

What I did:

start Hybrid
set 'Base->Processing->Audio' to 'passthrough (all)'
made sure 'Filtering->Support' was set to Avisynth
enabled 'Config->Internals->Avisynth->Always use Avisynth'
set an output file
added a new job
started the job processing

-> output was sync
next I switched to NVEncC as encoder, selected h265 as codec, added another job (with a different output file) and started that job.
-> output was sync

-----
Regarding the 10bit hevc thing, what happens if you call:

NVEncC.exe --check-features

I get:

Which indicates that I can't encode 10bit HEVC on my card with the current gpu and driver combination. (using a Geforce GTX 980 Ti here)
-> What does it indicate on your system?

Cu Selur

Ps.: Your card should come with a VP8 VPU which should support 10bit encoding. Hybrid uses the output of 'NVEncC --check-features' to determine whether the card support 10bit HEVC or not.
-> Triggering 'Config->Tools->Clear all cached tool infos', this will tell Hybrid to gather these options again.
