ReadyRead synchronous issue
Jeffson last edited by
I have an problem in implementing a udp socket buffer behavior in QT,
anyone can help me?
The details:I want to create a buffer to hold coming data,the "ReadyRead" slot is responsible for recieving.
After i recieve the packet,i want to play the packet which is in audio format.
The playing part is also implemented inside "ReadyRead" function.
The thing is when I play the packet,the "ReadyRead" blocked,did not recieve packet anymore,
which will cause the packet recieving delay.
how can make the recieving and playing synchronous?

you should consider to source out the "playing" (or the reading) into a different thread, so "reading" and "playing" can happen "simultaneously". Well reading will in fact always be some time ahead. Keep in mind how Youtube does and shows it in co-operation with your browser with the gray and red part of the progress bar.
I would call this pattern where one part does not wait on another to finish "asynchronous", though.
If you do a lengthy operation in the slot the events are waiting in a queue and nothing else is happening with your program. You need to use threads. Either put the UDP communication in a separate thread or the playback in a separate thread.
