软件介绍
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 16x16
Rate control with adaptive quantization, or constant quantization
Slice options: 1 slice per frame, N slices per frame, N macroblocks per slice, or N bytes per slice
Multiple threads automatically used for multiple slices
Temporal scalability up to 4 layers in a dyadic hierarchy
Spatial simulcast up to 4 resolutions from a single input
Long Term Reference (LTR) frames
Memory Management Control Operation (MMCO)
Reference picture list modification
Single reference frame for inter prediction
Multiple reference frames when using LTR and/or 3-4 temporal layers
Periodic and on-demand Instantaneous Decoder Refresh (IDR) frame insertion
Dynamic changes to bit rate, frame rate, and resolution
Annex B byte stream output
YUV 4:2:0 planar input
