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 or lag on some devices.
- Affected decoders: TI OMAP4, Allwinner A20
- Affected decoders: TI OMAP4 crashes, Allwinner A20, MT8176 lags (HEVC not affected)
2. Some H.264 decoders have a huge per-frame latency with the unmodified SPS sent from NVENC. Setting max_dec_frame_buffering=1 fixes this latency issue.
- Affected decoders: NVIDIA Tegra 3 and 4, Broadcom VideoCore IV, MT8176 (HEVC not affected)
- Affected decoders: NVIDIA Tegra 3 and 4, Broadcom VideoCore IV
3. Some decoders strictly require that you pass BUFFER_FLAG_CODEC_CONFIG and crash upon the IDR frame if you don't
- Affected decoders: TI OMAP4
