DM8168解码internal error打印及修复问题

cata yelo

DM8168在建立呼叫后，概率性出现如下错误打印，且会导致解码器异常，画面定格或黑屏，再也无法正常解码的挂死现象；

错误码集中在

0x2000a00，0x1021，0x1421，0xa10等，具体是什么原因导致的，如何修复（以确保解码器至少不要挂死，下次正确的I帧过来后能够修复），

你好；

你是否有通过错误码对照 H264_Decoder_HDVICP2_UserGuide.pdf 来分析报错的原因？

有分析过，原因有很多种，我们想首先做到不管什么原因，能否让解码器不会挂死，下次正确的I帧来到后可以修复，谢谢！

0x2000a00

0010

1100

Bit25，One or more slices are completely missing in this picture

bit11，Data problem/corruption

bit10, Insufficient input data

0x1021

Bit12, Header problem/corruption

Bit5, The SPS that a PPS/slice header referred to in this process call has not been received yet OR it was erroneous and thus invalid.

Bit0, Not even a single error-free slice header found in this process call, did not start MB loop

0x1421:

Bit10: Insufficient input data

0x4000:

Bit14: Unsupported input parameter
