Hi all,

What is the role of hardware device in MMF framework (HwDevice)???

Is it used for Hardware chip ??? or we can use it for s/w Codec also.

Suppose i want to play data using HwDevice and below HwDevice plugin, instead of hardware chip, we have some other layer which support software codec. Is it possible to use s/w codec instead of h/w codec??

Re: What is the role of HwDevice ?

The role is being an abstraction, it only provides a generic interface that every Hardware Device that decodes and/or encodes has to implement.

And yes, it's possible to use a s/w codec that is the purpose of CMMFSwCodecWrapper class .

Unfortunately the mmfswcodecwrapper.lib it's not included at the SDK.
