MJPEG Tools Svn

The hi-res option to mpeg2enc is -H not -h (which gives the usage summary)

tidy up the description of how the data is packed and use consistent
nomenclature - Y'/Cr/Cb instead of a mixture of YUV and Y'CrCb.

Fix broken no-MMX initialisation

4:1:1 bugfix submitted by Dan Scholnik

Add basis for a per-frame / pass-1 multipass rate controller

malloc.h is obsolete (and doesn't exist everywhere) use stdlib.h instead.

Tidy up mpeg2enc code to support switching of async frame input and
work with current main branch util libs etc.

The latest fixes to the development branch.

FreeBSD works now even with -M 2 specified to mpeg2enc. The problem was,
as suspected, that -pthread was not being used at compile and link time.
FreeBSD does not have -lpthreads nor integrated threads in libc, rather
a compiler option is used. The coredump in mpeg2enc was being caused by
pthread_attr_getstacksize() not being detected at ./configure time - and
the default stack size is far too small.

All better now.

autoconf's AC_SYS_LARGEFILE will do all the dirty work of finding the correct
flags for large file support. No need for a OS specific ("xLinux") check that
duplicates autoconf's builtin capabilities (which cover more systems anyhow).
