[Linphone-developers] Video receive\send buffers\birate control, h264.

[Станислав]

Hello!
I have found recently a thread about h264 new features - 
(http://x264dev.multimedia.cx/archives/249)
I'm trying to use these new features. With them its possible to get <100 
ms delay in video calls.
But there is some problems, and main is: buffers and packet sizes.
Is it possible to reduce(or remove) receive\send buffers in linphone and 
where we set video packet size(its set to 1440 by default ?)  ?
As you can see from thread above buffers are not needed if "single-frame 
VBV" and "Periodic Intra Refresh" features of h264 are used.
With "slice-max-size" we can set slice size to packet size and so 
buffers are not needed because every packet received = frame.
Also i can see there is code in linphone that can reduce bitrate of 
video if we get 10% frame loss...but there is no code to increase 
bitrate to its original value...?

When starting call i can see that bitrate is limited to 1500, where is 
code that set's that ? Can't found it.. :<

Second question - is it possible to make linphone write debug messages 
to log file ? Because it is really hard to debug it while watching debug 
windows (that don't have auto-scroll btw).

last - is it possible to make linphone to go fullscreen mode(windows 
with video) when video call is established ? And how i can add 50% 
transparent buttons to video-window(so button is on top of it and i can 
see video thru it) ? Like "End call" button (for touch screen use)? Help 
me please :<

p.s. sorry for my bad english and thanks for help!
