MPEG4 on PCA: B-VOP decoding and SVH visual tools

[jtorra]

I'm working on a project related to play MPEG4 videos on a PCA platform based on monahans CPU.

I could successfully run the sample code provided with IPP for this purpose. For our target device we would like to support a subset of MPEG4 Advanced Simple profile; that means that we should be able to decode B-VOPs and have Short Visual Header features.

This features aren't implemented in the sample code provided for PCA but are supported on the mpeg4 decoder sample code of IPP for x86. I've been reading the documentation provided on IPP for PCA and it gave me the believe that is possible implement this features on PCA too.

Please, could you give me some guidance about how to implement this features using IPP for PCA ? Which primitives should be involved ?

Do you have plans to extend the current decoder sample code in a near future supporting more MPEG4 Visual Tools ?

Could be possible also support Global Motion Compensation and Quarter-pel Motion Compensation features ? IPP for PCA provide primitives for this visual tools ?

Thanks in advance for you help.

Hello,

I recommend you to take a look on IPP for IXP42x, it is compatible with PCA255 processors and have quite advanced media sample, which includes several audio and video codecs, including MPEG4 with support Advanced Simple profile and global motion estimation.
