Recording only: fragment size. The server sends data in blocks of fragsize bytes size. Large values diminish interactivity with other operations on the connection context but decrease control overhead. It is recommended to set this to (uint32_t) -1, which will initialize this to a value that is deemed sensible by the server. However, this value will default to something like 2s, i.e. for applications that have specific latency requirements this value should be set to the maximum latency that the application can deal with. If PA_STREAM_ADJUST_LATENCY is set the overall source latency will be adjusted according to this value. If it is not set the source latency is left unmodified.
