Video sent with RTP only when closing a pipeline

[Monyz Wacon]

Hello,
today I built gstreamer + plugins from the source, version 1.7.90 and
everything started to work (the same pipeline, no changes).

Previously I installed gstreamer on Raspbian using apt-get and official
repositories, it seems that there is version 1.4.4-2 of gstreamer:

$ lsb_release -a
No LSB modules are available.
Distributor ID: Raspbian
Description:    Raspbian GNU/Linux 8.0 (jessie)
Release:        8.0
Codename:       jessie

$ sudo apt-get -s install "gstreamer1.0*"
[...]
Inst libgstreamer1.0-0 (1.4.4-2 Raspbian:stable [armhf])
[...]

Well, problem solved.
