--- Comment #7 from Tim-Philipp Müller <t.i.m at zen.co.uk> ---
Can't reproduce this here with 1.8.1 and

gst-launch-1.0 videotestsrc ! videoconvert ! x264enc ! flvmux ! rtmpsink
location=rtmp://4.31.30.153:1935/devapp/ramissue

(none of the above input streams work for me).

By default x264enc outputs very high quality with large internal buffers. You
should be able to tweak that via properties, e.g. by setting tune=zerolatency
and key-int-max and other properties.

Not sure what we can do here without massif logs and more info.
