How do I zero streambuffer of vpu?

[linzhang]

If vpu_DecGetBitstreamBuffer returned a zero space once, the following call of vpu_DecGetBitstreamBuffer will always return zero.

Hi lin,

The VPU requires a specific size resolution.  If the size changes the VPU instance has to be reinitialized.  This is because when the instance is instantiated physical memory is allocated based on the size specified.  Please check .MX 6Dual/6Quad VPU Application Programming Interface Linux Reference Manual / Document Number:VPU_API
