This file serves to document some of the decoder errata when using MediaCodec hardware decoders on certain devices. 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 OOM error on some 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.

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. 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.
