public uint32 util_seqnum_next
Return a constantly incrementing sequence number.
This function is used internally to GStreamer to be able to determine which events and messages are "the same". For example, elements may set
the seqnum on a segment-done message to be the same as that of the last seek event, to indicate that event and the message correspond to the
|A constantly incrementing 32-bit unsigned integer, which might overflow back to 0 at some point. Use
util_seqnum_compare to make sure you handle wraparound correctly.
