looks ok but i wonder if anyone is using the vfw ffv1 mkv in the
archiving universe on purpose. should we include a way to -vfw-codec-id
manual for those systems? maybe is unimportant but it would be good to
ask the ffv1 specification crowd about this change to mkv muxing. and
maybe resend patch separately from jpeg2000 decoding subject. hiding an
ffv1 change under jpeg2000 subj is weird.

said another another way, this change would change the checksums of
files if people tried to recreate their mkv. which is something that
archivists do sometimes.

e.g. old ffv1 mkv vfw codec_id
vs
new ffv1 mkv codec_id
