x264 rev2085+619 tMod
– Update libav with some extra codecs support.
Other updates in rev2085′s patch version:
– Now in this version lavf/ffms demuxers can return color range flags of source clip, and send those flags to x264. You can still override the flags using –fullrange on/off.
– aq-mode 3 updated.
– 10bit version of OreAQ available.
– More audio formats accepted to be muxed in mkv using lsmash.
– Fix help information of AVC profiles, i.e., adding available “high422″ and “high444″ info, and hide unavailable “baseline”, “main” and “high” in 10 bit builds.
Other minor changes won’t be mentioned. Download the patches below if details needed.
——– Attention on high bit depth usage ——–
Several days before madshi pointed out that x264′s internal low bit depth to high bit depth conversion and high bit depth to low bit depth dithering is incorrect. The present converting and dithering algorithms seem to work correctly on full range sources of RGB and Y plane of YUV. Till now neither x264 nor swscale has a correct chroma upscaling algorithm for full range sources, and I didn’t make one. Anyway, the converting algorithm of x264 is absolutely wrong on limited range sources, according to ITU-R 601/709′s standard, in which the conversion should be done by simply appending LSBs of zero to the source. The dithering algorithm may also causes overflow on limited range source. So I hacked on my tMod builds to solve this issue.
When the input and output bit depth are the same, no conversion or dithering will be apllied. Otherwise when used with “–fullrange on”, the conversion and dithering will be exactly the same with x264′s original algorithm, which is still not reliable for YUV sources, so it is recommanded to use your own reliable approaches to convert those sources by yourself before passing them to my x264 builds; if used without “–fullrange on”, the conversion will be done by shifting according to the standard, and the dithering algorithm is fixed as well, so that the result should be absolutely right.
