HI3531A解码B帧的问题

海思

各位好，目前在开发3531A的解码，想咨询各位大侠3531A（非3531）支持解码B帧吗？
我在测试解码B帧时，一旦设置解码通道参数stVdecVideoAttr.bTemporalMvpEnable为1，HI_MPI_VDEC_CreateChn就会出错，出错返回0xa0058003！

若可以解码B帧，请问怎么设置？希望大侠们给个建议，先谢谢了！！！！！！！！！

支持B frame

vdec 是什么模式? privateVB/moduleVB/userVB ?

ModuleVB，目前就是使用海思自己提供的demo；
支持B帧，内存分配方式有要求？
冒昧一句，能否有相关设置支持的demo供参考一下，谢谢。

你是指HI3531还是HI3531A啊？[/quote]

如果是moduleVB, 那么要支持B frame, vdec专用的VB要开两组VB, 楼主的VB是如何开的

如果是moduleVB, 那么要支持B frame, vdec专用的VB要开两组VB, 楼主的VB是如何开的[/quote]

自己主要修改了以下两个函数，修改部分为黑色粗体（USER_B_FRAME在编译里已定义）
