Subject: Use RTPDynamicProtocol parse_sdp_a_line() handlers in case of unknown SDP
X-Git-Tag: v0.5~2910
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8646b9070bb3104e1c3f35baeb652740f58bff9c;p=platform%2Fupstream%2Flibav.git

Use RTPDynamicProtocol parse_sdp_a_line() handlers in case of unknown SDP
lines. This allows "private" SDP tags to be forwarded to the specific handler,
allowing protocol-specific handling of SDP data. See mailinglist discussion
in the "Realmedia patch" thread.
