![]() ![]() ![]() The latest Mac OS X 10.8 gcc and clang based compilers can build x265 using the linux instructions above. # Note: if the packaged yasm is older than 1.2, you must download yasm (1.3 recommended) and build it ![]() $ sudo apt-get install mercurial cmake cmake-curses-gui build-essential yasm Parallel encoding on multiple CPUs, both frame-level and wavefront parallelism ![]() Ratecontrol: constant quantizer, constant quality, single pass ABR, optional VBV Inter B: partitions from 64圆4 down to 8x4 (including all merge modes Inter P: all partitions (from 64圆4 down to 8x4) Intra: all block types (32x32, 16x16, 8x8, 4x4, and PCM with all predictions) View full changelog All featuresįull prediction and transform quad-tree recursion supportedī-frames as references / arbitrary frame order QP spikes in the row-level VBV rate-control when WPP enabled.Įncoder crash in -abr-ladder. Incorrect VBV lookahead in -analysis-load + -scale-factor.Įncoder hang when VBV is used with slices. New x265_param options -min-vbv-fullness and -max-vbv-fullness to control min and max VBV fullness. Support for RADL pictures at IDR scene cuts: Improves coding efficiency with no significant impact on performance.īidirectional scene cut aware Frame Quantizer Selection: Saves bits than forward masking with no noticeable perceptual quality difference.Īdditions to x265_param structure to support the newly added features and encoder enhancements. Improved hist-based scene cut algorithm: Reduces false positives by leveraging motion and scene transition info. Real-time VBV for ABR (Average BitRate) encodes in –pass 2 using -vbv-live-multi-pass: Improves VBV compliance with no significant impact on coding efficiency. ![]()
