This works similarly to ff_network_wait_fd, but waits up to 'timeout' microseconds Uses ff_network_wait_fd in a loop.

Socket descriptor Set 1 to wait for socket able to be read, 0 to be written Timeout interval, in microseconds. Actual precision is 100000 mcs, due to ff_network_wait_fd usage

int_cbInterrupt callback, is checked after each ff_network_wait_fd call
0 if data can be read/written, AVERROR(ETIMEDOUT) if timeout expired, or negative error code
