Re: Theora got extreamly slow (Makefile.am was changed)

thanks Leonardo


In my application there are two threads. One is the theora encoder the other
is a bandwidth measuring program.

Both of them are working properly when they are separated. (theora is
obviously working properly, bandwidth measuring component also working
properly)

So this problem is occurred when both these are joined (encoder is the main
thread, bandwidth measurer is the child thread)

So i think that the problem is with my makefile. Please can anyone help me
to find the problem

If you want more information I can give it


thanks in advance
