VapourSynth crashing on large files
#3
Thanks for the suggestions.

I'm working on a i7-4771 // 8GB DDR3 // GTX960 2GB, nothing overclocked, C: has 34GB and D: has 50GB free space.

Setting bestsource=cpu didn't help, nor using FFMpegSource2 or LWLibAVSource. I remember setting bestsource=cuda because that somehow caused some succesfull encodes (although that shouldn't make any sense...)
Maybe this is relevant: I remember cropping the previous 30min beforehand and applying the CCD filter in VirtualDub2, before applying VapourSynth filters and encoding with Hybrid (cropping & letterboxing disabled).

Went to an i5-9600KF // 16GB // GTX1070ti 8GB and tried encoding the same video with same VapourSynth filters on. Crashed again, almost instantly. Then set bestsource=cuda & disabled VapourSynth CCD, did a VapourSynth preview (compare view) do be sure the VapourSynth was working, and managed to get it encoded untill around 50%... then crash.
Then set bestsource=cpu and x264 profile=High (instead of High4:2:2 with 8-bit precision), and got it to 100%!
-> enabled audio encoding to FLAC: success
-> enabled CCD: crash
-> disabled CCD, enabled cut support (frame selection): crash

Went back to my other machine and tried to repeat the same actions... and got to a 100%! (no audio or CCD enabled. Tried enabling cut support and encoding did start but crashed underway)

All this actually feels so random... I could swear I had tried the exact same settings on my i7 before, and now it suddenly works? Is there any way to know where in the process the crash occurs? Is it a x264 thing, or is Vapoursynth crashing?

Thanks
Karel

p.s.  I have another i9-13900H laptop (with no dedicated graphics card) I can test on...
