- the first audio and video packs now contain only a system header and lots
of padding.
- no system headers in any packs other than the first ones
- the two system headers only contain information about "their" stream
- fixed some header values (muxrate, some flags, ...) so that they have the
values specified by the standard
- padding packs are inserted if the mux rate would be below 75 packs per
second (the rate must not be below or above that value).
- fixed the SCR of the packs
- 20 zero bytes are now inserted at the end of each audio pack, after the
data packet

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
