+ Add a deinterlacer plugin based on the tvtime/DScaler deinterlacer,
+ which was relicensed to LGPL for GStreamer and in theory provides
+ better and faster results than the simple deinterlace element.
+ Fixes bug #163578.
+
+ Ported to GStreamer 0.10 but still not enabled or included in the
+ build system by default because of bad artefacts caused by a bug
+ somewhere and as it can be only build on x86/amd64 ATM and requires
+ special CFLAGS. Will be fixed soon.

+
+ MultiMedia eXtensions GCC interface library for IA32.
+
+ To use this library, simply include this header file
+ and compile with GCC. You MUST have inlining enabled
+ in order for mmx_ok() to work; this can be done by
+ simply using -O on the GCC command line.
+
+ Compiling with -DMMX_TRACE will cause detailed trace
+ output to be sent to stderr for each mmx operation.
+ This adds lots of code, and obviously slows execution to
+ a crawl, but can be very useful for debugging.
+
+ THIS SOFTWARE IS PROVIDED ``AS IS'' AND WITHOUT ANY
+ EXPRESS OR IMPLIED WARRANTIES, INCLUDING, WITHOUT
+ LIMITATION, THE IMPLIED WARRANTIES OF MERCHANTABILITY
+ AND FITNESS FOR ANY PARTICULAR PURPOSE.
+
+ 1997-98 by H. Dietz and R. Fisher
+
+ History:
+ 97-98* R.Fisher Early versions
+ 980501 R.Fisher Original Release
+ 980611* H.Dietz Rewrite, correctly implementing inlines, and
+ R.Fisher including direct register accesses.
+ 980616 R.Fisher Release of 980611 as 980616.
+ 980714 R.Fisher Minor corrections to Makefile, etc.
+ 980715 R.Fisher mmx_ok() now prevents optimizer from using
+ clobbered values.
+ mmx_ok() now checks if cpuid instruction is
+ available before trying to use it.
+ 980726* R.Fisher mm_support() searches for AMD 3DNow, Cyrix
+ Extended MMX, and standard MMX. It returns a
+ value which is positive if any of these are
+ supported, and can be masked with constants to
+ see which. mmx_ok() is now a call to this
+ 980726* R.Fisher Added i2r support for shift functions
+ 980919 R.Fisher Fixed AMD extended feature recognition bug.
+ 980921 R.Fisher Added definition/check for _MMX_H.
+ Added "float s[2]" to mmx_t for use with
+ 3DNow and EMMX. So same mmx_t can be used.
+ 981013 R.Fisher Fixed cpuid function 1 bug (looked at wrong reg)
+ Fixed psllq_i2r error in mmxtest.c
+
+ * Unreleased (internal or interim) versions
+
+ Notes:
+ It appears that the latest gas has the pand problem fixed, therefore
+ I'll undefine BROKEN_PAND by default.
+ String compares may be quicker than the multiple test/jumps in vendor
+ test sequence in mmx_ok(), but I'm not concerned with that right now.
+
+ Acknowledgments:
+ Jussi Laako for pointing out the errors ultimately found to be
+ connected to the failure to notify the optimizer of clobbered values.
+ Roger Hardiman for reminding us that CPUID isn't everywhere, and that
+ someone may actually try to use this on a machine without CPUID.
+ Also for suggesting code for checking this.
+ Robert Dale for pointing out the AMD recognition bug.
+ Jimmy Mayfield and Carl Witty for pointing out the Intel recognition
+ bug.
+ Carl Witty for pointing out the psllq_i2r test bug.

+ This is still extremely alpha.
+ Because this library depends on an assembler which understands the
+ SSE opcodes, you probably won't be able to use this yet.
+ For now, do not use TRACE versions. These both make use
+ of the MMX registers, not the SSE registers. This will be resolved
+ at a later date.
