Subject: jitterbuffer: provide a clock.
X-Git-Tag: 1.19.3~509^2~7916^2~313
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6cb0efede4f3c208c09855172c362b40252a96f2;p=platform%2Fupstream%2Fgstreamer.git

jitterbuffer: provide a clock.

since we are using the clock for sync, we need to also provide a clock for good
measure. The reason is that even if downstream elements provide a clock, we
don't want to have that clock selected because it might not be running yet.
