Parameters: latency, retry-interval, reorder-buffer, max-retries
These parameters are needed to properly fine tune the algorithm. I have added sensible defaults that should cover your typical connections but they need to be adjusted for unusually high (or low) round trip times.
nack-type is needed for when the sender only supports one of the two types.

packet-size allows you to adjust to the MTU of the network.

poll-timeout could be lowered from the default of 5ms when the demux/decoding chain cannot tolerate that much jitter. A lower value comes at the expense of a tighter loop and more CPU usage.

Lastly, eof-on-reset allows you to control the behavior of the buffer reset event. Depending on the type of output, eof is more adequate than sending a timestamp discontinuity down the chain.

- missing NEWS, po/POTFILES.in, modules/MODULE_LIST entries
- you must surround the poll.h include with HAVE_POLL
- use str*cpy instead of strcpy

Also, you have many options in this module. Are they all necessary?
