Open Source H.264 Codec

OpenH264 is a codec library which supports H.264 encoding and decoding.
It is suitable for use in real time applications such as WebRTC.

Encoder Features:
* Constrained Baseline Profile up to Level 5.2 (Max frame size is 36864 macro-blocks)
* 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
* Simulcast AVC up to 4 resolutions from a single input
* 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

Decoder Features:
* Constrained Baseline Profile up to Level 5.2 (Max frame size is 36864 macro-blocks)
* Arbitrary resolution, not constrained to multiples of 16x16
* Single thread for all slices
* Long Term Reference (LTR) frames
* Memory Management Control Operation (MMCO)
* Reference picture list modification
* Multiple reference frames when specified in Sequence Parameter Set (SPS)
* Annex B byte stream input
* YUV 4:2:0 planar output
