I would focus on zero lantency encoding to start with. You can try with
x264enc tune=zero-latency . It is most likely that current pipeline runs
slower then real time, which may cause packet loss. UDP miss-ordering
could also become an issue with such a pipeline. If RAM is not an issue,
you can add a queue.

If you're pipeline is really too slow and you only need to crop, use
videocrop top=-1 buttom=-1 right=-1 left=-1 instead of videobox, it's
less expensive.

good luck,
Nicolas
