x264 Video Codec r1703 for 32bit

codice:
latest changes:
- CAVLC "trellis"
~3-10% improved compression with CAVLC.
--trellis is now a valid option with CAVLC.
Perhaps more importantly, this means psy-trellis now works with CAVLC.

This isn't a real trellis; it's actually just a simplified QNS.
But it takes enough shortcuts that it's still roughly as fast as a trellis; just not quite optimal.
Thus the name is a bit of a misnomer, but we're reusing the option name because it does the same thing.
A real trellis would be better, but CAVLC is much harder to trellis than CABAC.
I'm not aware of any published polynomial-time solutions that are significantly close to

x264 Video Codec 1732

1732 32bit
md5: 44dfede82f97391ab5447e007ced36c6

Latest changes:
* dd High 10 Intra profile support (AVC-Intra)
* x264 should now be able to encode compliant AVC-Intra 50.
* With a 10-bit-compiled version of x264, a sample commandline for 1080i25 might be: --interlaced --keyint 1 --vbv-bufsize 2000 --bitrate 50000 --vbv-maxrate 50000 --nal-hrd cbr

* Also print "Constrained Baseline" for baseline profile, since that's all x264 (and everything else in the world) supports.
* Also reorganize parameter validation a bit to reduce some spurious warnings.

x264 Video Codec rev1772


Improve flash detection algorithm change in r1765
Now only disables scenecuts only near real end of video, not just prior to forced keyframes.
