In my latest status, I able to have the conference with polycom and other softphone using H.264 plugin.
But I face the problem of delaying (my movement only show on the other endpoint after around 5 seconds in local network). I think this problem occur because of fragmentation of 1 encoded picture that has size greater than 1.4KB to multiple slices, then sent it out.
Currently, my default frame rate is 10fps.
My question is how to solve the delaying problem because I see polycom PVX 8.0.2 and other softphone do not have any delay?
Another question, If my default frame rate is 10fps, is it means that my program will call Codec Encode function 10 times in a second?
As I know, inside the encode function, every time it will check for remanding frame length for last packet, if exist it repeatably packet it with size less than 1.4KB until finish, then it only start to encode a new frame.
So, Let say I have one encoded picture that consist of 10 slices, is it means that I only able to sent one complete picture in 1 second (if my fps=10)?
