Windows / Мультимедиа / Кодеки / x264 Video Codec 1649
x264 Video Codec 1649
x264
Video Codec - это cвободная библиотека программных компонентов
для сжатия/конвертации видео в формат H.264/MPEG-4 AVC. Кодек
x264 отличается большой скоростью работы и отменным качеством
итогового видеоматериала.
MPEG-4 is a broad Open Standard
developed by the Moving Picture Experts Group (MPEG), a working group of
the International Organization for Standardization (ISO) which also did
the well known MPEG-1 (MP3, VCD) and MPEG-2 (DVD, SVCD) Standards,
standardizing all sorts of audio/video compression formats and much more
By its nature the MPEG-4 Standard doesn,t aim at
standardizing one potential product (e.g. something comparable to DVD)
but covers a broad range of Sub-Standards, which Product Providers can
choose from to follow, according to what they need for their product
The AVC/H.264 standard defines four different Profiles: Baseline,
Main, Extended and High Profile: - Baseline Profile offers
I/P-Frames, supports progressive and CAVLC only - Extended Profile
offers I/P/B/SP/SI-Frames, supports progressive and CAVLC only -
Main Profile offers I/P/B-Frames, supports progressive and interlaced,
and offers CAVLC or CABAC - High Profile (aka FRExt) adds to Main
Profile: 8x8 intra prediction, custom quants, lossless video coding,
more yuv formats (4:.4:....)
Features: ·
CAVLC/CABAC · Multi-references · Intra: all macroblock types
(16x16, 8x8, and 4x4 with all predictions) · Inter P: all
partitions (from 16x16 down to 4x4) · Inter B: partitions from
16x16 down to 8x8 (including skip/direct) · Ratecontrol: optional
VBV, single or multipass ABR, constant quantizer · Scene cut
detection · Adaptive B-frame placement · B-frames as
