Re: [Linphone-users] OSK5912: GSM works but all other codecs give "must catch up warning" and audio breaks up

[Simon Morlat]

Hi,

The catchup warning happens when the media streaming thread is out of cpu.
I know the GSM codec uses only fixed point operations.
Maybe it's not the case for PCMU/PCMA, or maybe those codecs use an 
instruction that works very slowly on your board.
The code is in mediastreamer/g711common.h

There is no compile option to ask linphone not to use floating point 
operations.
