[x264-devel] x264 + avisynth + qtreader.vfp = hangs after finished

[edgar.soldin at web.de]

hi,

i can reproduce this all the time. with x264 win32 revisions 2008-2016 and avisynth 2.58 or 2.6mt set builds. the problem as observed is:

using a batch script to do a two pass encode hangs after the first pass until the x264 process is killed manually. the output suggests it is finished, it does not eat up any processor time anymore and the files generated are valid so far.

this only happens when 
- a virtualdub plugin to read Quicktime files is used (qtreader.vfp) 
- the src MOV is ProRes encoded.
other avisynth readers do not provoke this behaviour. unfortunately qtreader is the only avisynth source that is color safe and stable for feature length encodes. the alternative qtsource is colorsafe but crashes on longer encodes.
alternative ffmpeg or libav readers all shift colors according to my tests.

to reproduce follow these steps:

make sure
 avisynth 2.58 is installed
  http://sourceforge.net/projects/avisynth2/
 quicktime is installed
  http://www.apple.com/quicktime/download/
 prores codec is installed
  http://support.apple.com/kb/DL2
 MOV file, avs script and x264 binary come with this download
download

extract and run batch file.

..thanks (for this great hq h264 encoder).. ede
