x264 freezes batch window

[halpme]

Hello.
When using x264 from a batch script (.bat) and i change to another app/folder, and back to the batch window, it freezes. (Program not responding)
And it stays that way until x264 is done with current pass.

I'm using these settings:
test.bat
x264.exe --pass 1 --bitrate 4975 --stats "independence.stats" --level 4.1 --threads auto --bframes 3 --me dia --ref 1 --subme 1 --no-dct-decimate --rc-lookahead 40 --partitions none --output NUL "independence.avs"
x264.exe --pass 2 --bitrate 4975 --stats "independence.stats" --level 4.1 --threads auto --bframes 3 --me umh --ref 5 --analyse all --no-fast-pskip --mixed-refs --subme 7 --trellis 1 --8x8dct --output "independence.264" "independence.avs"

The same happens if i use Start -> run -> cmd, and type in the x264 command from there.

I am using windows 7 professional 64bit, and i get the same error on two other computers using the same os.
And i always use latest x264.exe 32bit from x264.nl

Have anybody have similar problems? Kind of annoying.

I guess you're using CoreAVC as a decoder.
Use ffdshow, ffmpegsource, avcsource etc

Or don't use Avisynth at all, if you don't need to apply special filtering. x264 should be able to read most sources directly now...

I have seen a similar problem... If i use piping via ffmpeg to x264-64bit -- NO "freeze". If i use direct source reading via x264-64bit -- "freeze"... (all in Win7-64bit)

"freeze" -- mean that Win7 think that x264 not responding
