Subject: Call check_back_and_send_rr() function only in case of RTP as a transport.
X-Git-Tag: v0.5~1969
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6ff1f6153022821252de615858a6adf0b193eec0;p=platform%2Fupstream%2Flibav.git

Call check_back_and_send_rr() function only in case of RTP as a transport.
Don't call it for RDT, since it is unneeded and it doesn't provide a
RTPDemuxContext, leading to some memory errors. See "[PATCH] fix small
memory error in rtsp.c" thread on ML.
