2004-06-11clip input motion vectorsMichael Niedermayer
be somewhat more tollerant on invalid input return INT_MAX instead of -1 for unuseable mv/mb types as that ensures nicely that they arent used initalize limits earlier for b frames a few more asserts to check for out of picture vectors Originally committed as revision 3213 to svn://svn.ffmpeg.org/ffmpeg/trunk

replace ugly macros by always_inline functions, that way its much more readable and flexible as always_inline can simply be removed while the macros couldnt be about 0.5 % speedup with default parameters Originally committed as revision 3037 to svn://svn.ffmpeg.org/ffmpeg/trunk

2004-02-13multithreaded/SMP motion estimationMichael Niedermayer
multithreaded/SMP encoding for MPEG1/MPEG2/MPEG4/H263 all pthread specific code is in pthread.c to try it, run configure --enable-pthreads and ffmpeg ... -threads <num> the internal thread API is a simple AVCodecContext.execute() callback which executes a given function pointer with different arguments and returns after finishing all, that way no mutexes or other thread-mess is needed outside pthread.c Originally committed as revision 2772 to svn://svn.ffmpeg.org/ffmpeg/trunk
