is my patch for capturing TCH frame correctly? - baseband-devel

19 Jul 2012

Hi, everyone interesting the topic, this is my latest patch for TCH decode,
fix few bug;
but it not work well for TCH AMR decode, welcome everyone interesting it to
review it and
modify it!
the most problem now I think is the capture of the Correct TCH frame, at the
last ,there is
some output for analysis
