Subject: decodebin3: Don't send duplicated stream-start event
X-Git-Tag: 1.19.3~511^2~2187
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=06cf7440ce28d42768b0a980d67fc6f53c6cb7b9;p=platform%2Fupstream%2Fgstreamer.git

decodebin3: Don't send duplicated stream-start event

group-id in stream-start event might be updated in
parse_chain_output_probe (). This cause duplicated stream-start
twice with identical stream-id and seq-num, but only group-id is
different. Although there is no change, stream-start event will
be followed by the first buffer.
