This has become very strange- although I am starting to get lost in
amongst all my different tests and options- this particular error has
disappeared. I'm not sure what I changed exactly, but it may have been
the harddup at the end of the -vf options.

Another problem though has become more apparent- AC EOB marker is
absent. I do have an idea as to why though, when I stop encoding it
declares 0.480s more audio than video.

Therefore my question now becomes: how do I fix this? Can I remove
the .48s of audio at the beginning? I tried -audio-delay in both
positive and negative 0.480 with no result.
