8168解码错误码的含义

各位大神,我解码的过程中出现以下m3video的错误,请问错误码0x12001和0x401是什么含义呢?谢谢!

回复 Chris Meng:

你好,我已经查看了,可是还是不是很明白里面的意思,我是从FLV流中转换成H264的码流,然后再一帧帧放进解码器。

0x12001错误原因:Unsupported feature (FMO) is present in the bit stream, indicated while decoding a slice header

那我应该如何改呢?谢谢!

Chris Meng:

回复 stephen peng:

你好,

错误说明是码流里面使用了FMO,而FMO这个feature解码器不支持啊。就是解码器解不了这个有FMO的码流。

Chris Meng:

回复 stephen peng:

stephen peng从FLV流中转换成H264的码流

转码的时候能否不使能FMO?

stephen peng:

回复 Chris Meng:

这个主要是FLV源加入了B帧,导致解码出现问题了,后面只要将B帧去掉解码就正常了

Chris Meng:

回复 stephen peng:

你好,

谢谢你的反馈。IVAHD h264dec支持b frame解码,dvr rdk很早就支持b frame的h264码流的解码了(参考帧个数需要调整)。所以B frame应该不是导致问题的关键。

回复 Chris Meng:

Hi Chris Meng,

我目前实现了b frame的解码,但是display看起来并没有按照pts来显示,所以会出现播放的帧序不正确的问题,请教一下应该如何设置才能按pts来显示呢?谢谢!
