I will attache two samples:
"lead_interleave_always.avi" file was encoded with "interleave" option set
to "always" in the lead's encoder
"lead_interleave_never.avi" file was encoded with "interleave" option set
to "never" in the lead's encoder
ffmpeg decodes "lead_interleave_always.avi" file with visual misaligments,
original codec decodes it correctly
