OS X, udpsink, is there a way to reduce messagesize / split UDP messages into smaller ones?

thanks, you made my day ;-)

for the record:

osx (10.6, 10.7, 10.8) limits udp message size to 9216 Bytes, so one has to use chopmydata max-size=9000 like this:

/opt/local/bin/gst-launch-1.0 -vvv -m videotestsrc is-live=true  ! video/x-raw, format=I420, width=1280, height=720, framerate=5/1, pixel-aspect-ratio=1/1, interlace-mode=progressive \
! queue ! x264enc tune=zerolatency speed-preset=ultrafast bitrate=1000 ! queue ! mpegtsmux ! queue ! chopmydata max-size=9000 ! udpsink host=10.44.1.21 port=1234



result (no errors anymore):
