-vf setsar and avisynth

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Creat an avisynth file (test.avs).
2. Use "-vf setsar" in ffmbc.


What is the expected output? What do you see instead?
I'm trying to set pixel aspect ration for the output file in ffmbc, using  
avisynth as input. If setsar is used on normal video file it works, but doesnt 
with avisynth. It just stops after setsar is used.
Latest FFmpeg build from Zeranoe doesn't have this problem and works without 
any problems.


What version of the product are you using? On what operating system?
FFmbc-0.7rc7-win32-120705
ffmpeg-20130310-git-586ae70-win32-static
AviSynth 2.5.8
Windows 7 x64
