VirtualDub2: Video compression error: An unknown error occurred (may be corrupt data)

This will continue the discussion from this thread:


basically, when trying to encode using virtualdub2's internal x264-8bit plugin, first attempt sometimes works, however, subsequent attempts fail as well as run video analysis with following error:

VirtualDub Error
Video compression error: An unknown error occurred (may be corrupt data). (error code -100)
Latest mmap zip is there:


showing memory consumption in various stages.. we can add more data to this thread as it is needed. Another important finding is while looking at vdub using process explorer found:

ffdshow.ax is "loaded" in memory map, not sure if that is expected?

also, noticed 'x264vfw.dll' loaded, but the compression chosen is the builtin x264-8bit, NOT the one down at the bottom: x264vfw!!

This reproduces with latest as well as older vdub2, I suspect something at the OS (windows 10) is somehow causing this to mixup/messup/pollute the limited address space for vdub32...
