思科的H.264编码器OpenH264.zip

OpenH264 是思科公司发布的一个开源的 H.264 编码和解码器。编码器特性Constrained Baseline Profile up to Level 5.2 (4096x2304)Arbitrary resolution, not constrained to multiples of 16x16Rate control with adaptive quantization, or constant quantizationSlice options: 1 slice per frame, N slices per frame, N macroblocks per slice, or N bytes per sliceMultiple threads automatically used for multiple slicesTemporal scalability up to 4 layers in a dyadic hierarchySpatial simulcast up to 4 resolutions from a single inputLong Term Reference (LTR) framesMemory Management Control Operation (MMCO)Reference picture list modificationSingle reference frame for inter predictionMultiple reference frames when using LTR and/or 3-4 temporal layersPeriodic and on-demand Instantaneous Decoder Refresh (IDR) frame insertionDynamic changes to bit rate, frame rate, and resolutionAnnex B byte stream outputYUV 4:2:0 planar input解码器特性Constrained Baseline Profile up to Level 5.2 (4096x2304)Arbitrary resolution, not constrained to multiples of 16x16Single thread for all slicesLong Term Reference (LTR) framesMemory Management Control Operation (MMCO)Reference picture list modificationMultiple reference frames when specified in Sequence Parameter Set (SPS)Annex B byte stream inputYUV 4:2:0 planar output支持的操作系统Windows 64-bit and 32-bit (initial release is only 32-bit, 64-bit will follow soon)Mac OS X 64-bit (initial release does not include this target, will follow soon)Linux 64-bit and 32-bit (initial release is only 32-bit, 64-bit will follow soon)Android 32-bit (initial release does not include this target, will follow soon)iOS 64-bit and 32-bit (not supported yet, may be added in the future)支持的处理器Intel x86 optionally with MMX/SSE (no AVX yet, help is welcome)ARMv7 optionally with NEON (initial release does not include this target, will follow later)Any architecture using C/C fallback functions
