fallback from "Use only decoder" mode for NVENC

[Mimo]

Hi,

is there a possibility to implement a fallback from "Use only decoder" mode ?
It is little annoying to recreate jobs due to this ...Please, read the 'Infos needed to fix&reproduce bugs,..'-sticky before you post about a problem.

I have no clue what such a fallback should do.

NVEncC has no option that allows to first test hardware decoding and if that fails automatically use software decoding.

Only thing that comes to mind I could do is add some checks to abort the job creation, if NVEnC + 'use only decoder' is selected, but the input is not one of these formats:

• MPEG-1
  
• MPEG-2
  
• VC-1
  
• VP9
  
• H.264
  
• H.265

Ya, this is one way, but it might not work always as i have many times H264 videos where is nvenc crashing when use encoder only.

I have in mind something like that if there is a crash after use only encoder then start job without use only encoder parameter. ...

And this behavior can be switch on in internal config f.e.

I have in mind something like that if there is no stream after use only encoder then start job without use only encoder parameter. ...

Okay, that won't happen.

-> I'll add an additional check to Hybrid during the job creation for the next release.

Ok.

This would save me a lot of time to reset crashed jobs, but thanks anyway for the perfect tool.

Found some time and send you a link to a dev version via pm which adds some additional checks during job creations.

it is now filtering out AVC videos ...

so it is not working correctly for me .

other question:

how to resize only files with some resolution higher as some value ?

There is no such option in Hybrid atm., but I can probably write one,..

made a typo, fixed it locally will send you a new version in ~1hr.

ok, so filter is correct but nvenc is still crashing, even stream is AVC.

here is media info for one not working :

due this situations i was talking about fallback scenario.

No clue why NVEnc would have problems with such a file.
-> Create a debug output and share it.
