RTSPWatch.waitBacklogUsec

gstrtsp.types.RTSPResult waitBacklogUsec(long timeout)

Wait until there is place in the backlog queue, timeout is reached or watch is set to flushing.

If timeout is 0 this function can block forever. If timeout contains a valid timeout, this function will return [gstrtsp.types.RTSPResult.Etimeout] after the timeout expired.

The typically use of this function is when gst_rtsp_watch_write_data returns [gstrtsp.types.RTSPResult.Enomem]. The caller then calls this function to wait for free space in the backlog queue and try again.

Parameters

timeout a timeout in microseconds

Returns

[gstrtsp.types.RTSPResult.Ok] when if there is room in queue.

[gstrtsp.types.RTSPResult.Etimeout] when timeout was reached. [gstrtsp.types.RTSPResult.Eintr] when watch is flushing [gstrtsp.types.RTSPResult.Einval] when called with invalid parameters.
