rtspconnection: Need to implement to get current queued messages and amount of bytes
Submitted by Hyunjun Ko
Currently, rtspconnection supports to get maximum bytes and the number of messages in the queue by the function gst_rtsp_watch_get_send_backlog.
But it's not supporred to get current status of the queue.
I think it's needed by user, especially, who needs to know the current status like amount of bytes queued.
If users get it, user could control flow data manually by adjusting bitrate or something like that.
If a function gst_rtsp_watch_get_current_backlog is implemented, it would be good.
What do you think about this?
