Subject: Remove reference to the "frame" term in variable names. Simpler and
X-Git-Tag: v0.7b1~2853
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=dc4a50a073191075b2093a016defcbd55b043a99;p=platform%2Fupstream%2Flibav.git

Remove reference to the "frame" term in variable names. Simpler and
more consistent with the function names.
