The block-based codecs 37/47/48 work on the full frame, and there's no
existing LucasArts game video that uses left/top offsets for these,
as it doesn't make sense. Ignore the left/top parameters for these codecs.

This is a replacement in ffmpeg for the deprecated avcodec flag
AV_CODEC_FLAG_DROPCHANGED.
This option is meant to be used when the filtergraph should not be
reinited upon input parameter changes as that leads to loss of state
in the filtergraph potentially leading to broken or aborted output,

LGTM.
Buffer pools should be used instead of making individual buffers. And
for buffers we import, I've added a new function which takes care of
this in my FFv1 patchset.

Hi! Thanks for the feedback.I have no problem adding the "X-" prefix

The size of the video frame (FOBJ) of the old codecs (ANIMv0/1/2) can
very reliably be determined:

This codec alternatingly skips and changes existing pixels.
A second 16bit parameter in the FOBJ header indicates how to do
