Subject: indeo3enc: fix handling of skipped frame
X-Git-Url: https://git.nihav.org/?a=commitdiff_plain;h=ab6fcc36bd8b35484b2c942ee67e50f4142ca9ec;p=nihav.git

indeo3enc: fix handling of skipped frame

Previously it forgot to _not_ update buffer reference, leadring
to decoders reading from the wrong previous frame.
