Subject: rtph264depay: profile-level-id is an optional parameter
X-Git-Tag: RELEASE-0.10.22~15
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e053a89c21b0d6f52867131c1d3473bc4ae74704;p=platform%2Fupstream%2Fgst-plugins-good.git

rtph264depay: profile-level-id is an optional parameter

So, if needed, extract the corresponding info from
sprop-parameter-sets.

Based on patch provided by <dxssx at gmail.com>

Fixes #612657.
