The primary changes in this release are the completion and tuning of the psycho-visual optimizations and new support for multiple pass encoding.
–psy-rd and –psy-rdoq are now completed and scaled such that their recommended initial values are 1.0.
Multipass encodes are now possible with –pass N and –stats FNAME
As usual, full documentation is at: http://x265.readthedocs.org/en/1.3/
= API Changes =
* param.bEmitInfoSEI, –[no-]info
include an SEI identifying the encoder and encoding options.
* param.bHighTier –high-tier
specify tier (used in conjunction with –level-idc)
* param.bEnableFastIntra –[no-]fast-intra
Use a gradient descent to scan angular intra modes
optional indicator of total frame count, may improve rate control
specify custom quantization matrices, “default” or filename
Psycho-visual optimizations for quantization
The first pass of multi-pass encodes will run in *turbo* mode unless this option is enabled.
