Which Mali packages are required for the best graphic performance of video playing on Direct FB?

Hi,

I have few basic questions about Mali packages.

Please understand my lack of understanding in this field.

My company designed a new board in purpose of playing HD videos on Linux DirectFB envionment.
And the video player would may be VLC player.

In my case which packages are required for the best graphic performance?

OpenGL ES can enhance the graphic performance?

Does it because fbdev uses 3D APIs?

If 3D APIs are not required, can I replace OpenGL ES with OpenCL?

Additionally do I need to port OpenCL to enable NEON? Or NEON can be utilized without OpenCL or OpenGL ES?

PLEASE please help me.

Project time schedule is quite desperating..

Thank you.
