Subject: alsa-audio-dec: explicitly cast the delay to a signed int64
X-Git-Tag: v10_alpha1~118
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=089fac77a6bf9199a5ec161e9c27850f0a680541;p=platform%2Fupstream%2Flibav.git

alsa-audio-dec: explicitly cast the delay to a signed int64

Otherwise the expression will be evaluated as unsigned, which will break
when the result should be negative.
