x264 rev2106+623 tMod

24th October 2011, Monday Leave a comment Go to comments

Latest updates:
– x264 rev 2085->2106;
– Support writing metadata and copyright to mp4 output;
– Support H.264 4:2:2 decoding via lavf and ffms demuxer;
– Re-enable –tune “touhou” in help, which is actually still available after being removed from full-help but….

——– 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.

    –tune touhou was removed from the help list, because the devs wanted to have it there as an easter egg. (I overheard that in the channel.)

      That’s really interesting. Maybe I shouldn’t have brought it out in open….
