I noticed that when I use an AVISynth script as
input to producer for 2-pass encoding, memory
usage almost doubles during the 2nd pass, even
though producer completely shuts down the
DirectShow reader before starting the 2nd pass.

So I ran another test, where I asked producer to
encode a directory with five AVS files. Producer
will then batch encode all the files in the
directory individually. What happened was that for
the last file,
producer's memory use was at 300 MB!  

I have seen this with many previous versions of
AVISynth, but this specific example is with 2.5.

Could it be something about how producer shuts
down the DirectShow reader, or a problem with how
DirectShow interacts with AVISynth? The reason I
ask this, is because doing a 2-pass XviD encode in
VirtualDub with the exact same AVS input, memory
usage does /not/ increase. 


My AVS scripts generally look something like
LoadPlugin
("C:\MISC\DVDTools\x2real\bin\avisynth\mpeg2dec\mpeg2dec.dll")
stream=MPEG2Source("L:\source.d2v")
audiofile=WAVSource("L:\source.wav")
stream=AudioDub(stream,audiofile)
stream=BilinearResize(stream,720,480)
stream=Trim(stream,0,2000)
return(stream)

I did some work on this issue with AviSynth source code to aid
debugging, and found indications that the problem lies somewhere in
producer.
See http://forum.doom9.org/showthread.php?s=&threadid=47893
for all the details.  Have not looked into producer's dsreader.

It is not possible to use producer's AVI reader can not be used for
.avs files to check if this has a memory leak, since producer's AVI
reader does not use Windows AVI interface, which is required for
AviSynth to work correctly. The reason producer has its own AVI reader
and parser is to be able to read uncompressed AVIs on Linux and OS X.
