x264 Video Codec r1703 for 32bit
x264 Video Codec r1703 for 32bit
Code:
[B]latest changes[/B]:
- 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 optimal.28.08.2010

x264 Video Codec rev1713 for 32bit
Code:
[B]latest changes[/B]:
- Add support for level 1b
This level is a stupid hack in the H.264 spec, so it's a stupid hack in x264 too.
Since level is an integer, calling applications need to set level_idc=9 to use it.
String-based option handling will accept "1b" just fine though, so CLI users don't have to worry.

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.
