Preview + encode disaster !

[ToiletDuck]

While iam talking about the HWdecoding setting in Config→Input→Decoding→Use Gpu for Decoding=  section from hybrid 

That will be used if you don't use Avisynth or Vapoursynth and will crash is you select something that doesn't work.

REALY   → !?! 

I could have sworn, the first thing i did when i encountered that preview filter issue = Deselecting → HWencode totaly under input tab.. 
And that ↑ immediatly solved the problem    .  

what else , what other setting could have fixed / worked around that issue, since Libav HWdecoding is only for Intel/nvidia users...
I would guess "filesize", but the workarround did overcame that issues with that big file  

Strange thing is, when I indexed it with FFVideoSource, closed the preview and reindexed it, is was faster.

Could it be a Windows disk caching issue?

By disk cache, iam guessing you are refering to write caching for SSD/HDD ?  Do you?
Or are you refering to the reserved memory space (RAM) to write to and read from ?
And there is the swap/page file too..


It's best to enable that in device manager me thinks..

But more importantly, erratic speeds can be due to the ssd firmware, bios mobo, even device driver etc ...  
I wish it only wos that easy to improve speed by flipping an switch (registry/background services etc..)   



Anyway, was it faster like in → did u saw the preview window in a snap of a finger (Litterally) ?

If so, i keep mention that..  

With LWlibav, each time you tune the filters , lwlibav needs to created the index file from scratch ... 
The waiting game all the time untill the preview pops up ! 


With FFmpegSource2 it's way different, it only create the index just ONCE yes, ONE TIME, to get the preview to see, no matter what you change or enable what filter you get to see that window like INSTNANTLY ... Boom   
I mean, could it be that ffmpegsource2 stores an portion of that media in the ram (or ramdisk)..  


Because ,i saw via islc that my 32GB ram sinks quite a bit using ffmpegsource2   


And just to be sure, u did tried this out using Ffmpegsource2 did you?


cheers,
