This file serves to document some of the decoder errata when using MediaCodec hardware decoders on certain devices.
1. num_ref_frames is set to 16 by NVENC which causes decoders to allocate 16+ buffers. This can cause an error on some devices.
- Affected decoders: TI OMAP4, Exynos 4

- Affected decoders: TI OMAP4, Allwinner A20
2. Some decoders have a huge per-frame latency with the unmodified SPS sent from NVENC. Setting max_dec_frame_buffering fixes this latency issue.
