x264 stalling at 100%

[nesburf]

Hi all

A new problem recently appeared where my x264 command line encodes all of a sudden will stall at either 99.9% or 100%. The file is never closed out so it ends up being a botched encode and I have to start over....usually it works on a second go, but for the life of me I can't figure out why it is randomly stalling like this now. I haven't changed anything in my avs script or x264 command line.

my avs scripts are as follows

SetFilterMTMode("QTGMC",2) 
avisource("filename.avi") 
ConvertToYV12(interlaced=true) 
assumebff() 
QTGMC(preset = "super fast", EdiThreads=4) 
Crop(8, 0, -8, -0)
bicubicresize(640,480) 
prefetch(threads=8)

and my x264 command line is

"x264.exe" --crf 17 --preset slow --level 3.1 -o "output.mp4" "input.avs"

any idea on what could be causing this, or where I could go to see some sort of logging which would give me a clue as to what's going on?

Thanks

WHAT version fo x264.exe you're using
Also, what version of Avisynth(+) do you have?

I haven't changed anything in my avs script or x264 command line.

BUT your operating system may have changed (stupid windows updates), also a recently installed/upgraded application might be causing some interference

any idea on what could be causing this

Does reducing the quantity of "prefetch threads" make some difference?

I was running the last komisar build of x264.exe...updated to 0.164.3086 now and still the same issue
avisynth + version is r3106 3.5

Hmmm I'll try reducing the prefetch threads, just weird that it hasn't been an issue before...you could be right about win10 updates causing this

the program might not have high enough administrative rights to create the final file wherever you are trying to put it. you might try right clicking on x264.exe and setting it to always run as admin.

definitely not the problem as I usually run it in batch and the first 4 will be fine and then all of a sudden stall on the fifth.

Trying removing the multi-thread altogether and seeing if that makes any difference

Also make sure your input&output&temp folders are expluded from any anti virus scanners and similar.

Again this morning...have a simple batch file that calls x264 to encode 23 files in a folder...It does the first 2 and then stalls when starting the 3rd....see screen shot
Checked windows event logs and nothing raises any flags. Can't for the life of me figure out what's going on. No virus scanning or anything is going on when this happens. This happens when I'm both encoding to a local drive as well as when I'm encoding on a network drive.

Reinstalled AviSynth Plus...couldn't upgrade to the newest version as my script broke and I couldn't figure out how to get QTGMC to work with it so I'm still running 3.5....arghhh this is getting really annoying!
