Subject: mp4mux: Disable aggregator's default negotiation
X-Git-Tag: 1.22.0~1669
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d2c6f21fc1b664c20a8eab926162fe23583f7fc7;p=platform%2Fupstream%2Fgstreamer.git

mp4mux: Disable aggregator's default negotiation

mp4mux can't negotiate caps with upstream/downstream and always outputs
specific caps based on the input streams. This will always happen before
it produces the first buffers.

By having the default aggregator negotiation enabled the same caps
would be pushed twice in the beginning, and again every time a
reconfigure event is received.
