Open Media Alliance (AOMedia), which oversees the development of video encoding formats AV1\/AV2, the immersive audio format IAMF, and the image format AVIF, has released the AVM 1.0.0 project, advancing the official reference implementation of the AV2 video encoder and decoder. AVM includes optimizations for processors based on ARM64, x86_64, and MIPS architectures, implemented using advanced instruction sets NEON, AVX2, SSE2\/3\/4, MSA, and DSPr2. The AVM code is written in C and is distributed under the BSD license.<\/p>\n
The AV2 codec does not require licensing fees and is developed as a successor to the AV1 format. Features of the AV2 codec:\n<\/p>\n
\n
Optimization for streaming applications;\n<\/li>\n
Improved prediction of inter-frame changes;\n<\/li>\n
Significant performance improvement in compression operations compared to AV1;\n<\/li>\n
Extended support for virtual and augmented reality capabilities;\n<\/li>\n
Support for a wider range of visual quality;\n<\/li>\n
The ability to simultaneously deliver multiple videos within a single stream, supporting separate display on the screen;\n<\/li>\n
Lisafunktsioonid m\u00fcra v\u00e4hendamiseks, kompressiooni artefaktide v\u00e4hendamiseks ja detailide s\u00e4ilitamiseks.\n<\/ul>\n
\u00dche AVM-i eksperimentaalse v\u00e4ljaande testimisel v\u00f5imaldas AV2 koodeki kasutamine saavutada bitikiirusel 32,59% v\u00e4henemist v\u00f5rreldes AV1 koodekiga samal kvaliteeditaseme korral, kasutades Netflixi v\u00e4lja t\u00f6\u00f6tatud kvaliteedi hindamise meetrikaid VMAF (Video Multi-Method Assessment Fusion). PSRN-YUV (Peak-Signal-to-Noise Ratio 14:1:1) meetrikate kasutamisel oli bitikiirus v\u00f5imalik v\u00e4hendada 28,63%. Samal ajal reageerides kasutajate tagasisidele, kes on testinud AVM-i teeki, j\u00e4tab k\u00f5rgete bitikiiruste kasutamisel t\u00f5husus ja kodeerimise kvaliteet siiani soovida.<\/p>\n
Nagu AV1 koodekis, kasutab AV2 h\u00fcbriidseid plokiorienteeritud struktuure, kuid erinevalt AV1-st toetab see suuremaid superplokke 256×256, t\u00e4iesti rekurssiivset jaotamist (partitioning) ning t\u00f5husamat heleduse ja v\u00e4rvi parameetrite jagamist. AV2-s kasutatakse \u00fchtset eksponentsiaalset kvantisaatorit, mis katab laiemat heleduse vahemikku ja tagab suurema kvantimise t\u00e4psuse 8-, 10- ja 12-bitise video jaoks, samuti paremini haldab madalat bitikiirus. Vahekaadrimuutuste ennustamise v\u00f5imalused on v\u00e4rskendatud, et parandada heleduse ja v\u00e4rvuse muutumise modelleerimise kvaliteeti, arvesse v\u00f5ttes mudeli koostamisel kuni 7 eelnevat kaadrit, toetades ajalikku (temporal) interpoleerimist ja paremini t\u00f6\u00f6tades k\u00f5rge resolutsiooniga v\u00f5i kiiresti muutuva sisu liikumatusega videotes. \n Allikas: opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"
