What to use for master-display when MediaInfo reports 'Display P3' ?
Code:
Color range : Limited Color primaries : BT.2020 Transfer characteristics : PQ Matrix coefficients : BT.2020 non-constant Mastering display color primaries : Display P3 Mastering display luminance : min: 0.0001 cd/m2, max: 1000 cd/m2 Last edited by Selur; 26th December 2017 at 13:49. Reason: added mediainfo output |

In the docs, it says that --hdr-opt should be used with AQ-mode on. --tune grain disables AQ-mode, so is it OK to use --hdr-opt anyway or better to leave it out? Also, it is said that the input video should be 10-bit 4:2:0. Is it safe to input 16-bit video (because of processing things in Vapoursynth in 16-bit land) if the original source is 10-bit 4:2:0 and signal --input-depth 16?

x265 2.6+24-69cfe46e8a3b – merge with stable
Several fixes e.g. in analysis and VBV handling; added support for RADL pictures; renamed options: Code:
--radl <integer> Number of RADL pictures allowed in front of IDR. Default 0 ( --analysis-reuse-mode <string|int> removed ) --analysis-save <filename> Dump analysis info into the specified file. Default Disabled --analysis-load <filename> Load analysis buffers from the file specified. Default Disabled |

I can see how that could reduce keyframe strobing and improve efficiency with fixed cadence encodes. Are there any downsides to it? Any compatibility issues? |

It actually sounds like a feature for closed GOP, because the importance of closed v.s. open GOP is during decoding, frames that are decoded after an IDR frame can be presented before it while only requiring data (in the decoded picture buffer) from the current GOP. Any RADL B frames would simply be dropped when seeking to the IDR frame.

from 2.6(+22 and +24), it seems some problem in my computer.

The term "current GOP" can be a bit confusing when we're talking about leading pictures. RADL B pictures require the IDR picture (the first frame of the next GOP) as a reference. But the decoder knows this already, as the NAL unit type of the IDR picture will indicate that leading pictures (from the previous GOP) follow the IDR picture in decode order (it will be an IDR_W_RADL as opposed to an IDR_N_LP - IDR with no leading pictures). |

Am I right in presuming that the latest "Meltdown" security issue, and the implemented KPTI fix, will not impact x265 much or at all?
From what I understand, its only multiple/regular kernel calls/ints that will cause a slowdown (TLB flush), and presumably x265 doesnt do many? (only file read and writes + text output) Although for me at least, I have Haswell (soon to be 8700k), so it has PCID, which will mitigate TLB flushes. Cheers Divxmaster |
