imx6 android - any API document/sample source for video hardware acceleration/decoder support

kenlin — Tue, 15 Apr 2014 07:23:39 GMT

Does freescale provide any API document or sample source for app developers to make use of hardware acceleration implementing video player fast forward (x1, x1.5, x2) or slow motion (x 0.5, ...) functions?

Hi Ken,

You can refer to the thread Android Graphic UI with GPU Hardware Acceleration in this community. If you are using the newer android BSP, in the doc of android 4.3 or 4.2 in freesacle official net there is a document named i.MX_6_G2D_API_User_Guide.pdf. Hope this can help you.
Have a great day,

Best Regards
Dan

Hi Dan,

Thank you for the reply.

I failed to search for i.Mx_6_G2D_API_User_Guide.pdf in the freescale official net (Search Results: i.MX_6_G2D_API_User_Guide.pdf). Could you please attach the user guide in this tracking case or let me know the specific download URL?

Cheers,

Ken Lin

Hi Dan,

The document (i.MX_6_G2D_API_User_Guide.pdf) said G2D Application Programming Interface (API) is designed to

simplify the use of the 2D BLT function. It seems not having to do with the hardware acceleration API support for implementing "video player" fast forward (x1, x1.5, x2) or slow motion (e.g. x0.5) functions.

Cheers,

Hi Ken,

Yes, you are right. It really do not have do with the hardware acceleration API. You can just refer to it . Since we do no have many documents on this field. I think the thread Android Graphic UI with GPU Hardware Acceleration may help you. If you have problems you can exchange your ideas under that thread with them.

Best Regards

Dan

Hi Ken,

Towards the video hardware acceleration/decoder questions you alo can go to create a Technical Service Request in freescale's official website. And our engineer will give you reply.

Hello Dan,

Where might I find a document which describes how the dithering works in the GPU? Most displays are 180bit panels and its common to use dithering to accurately display 24-bit graphics. Is this automatic when you select 18-bit output for the i.MX6? Thought maybe the GPU users manual you posted would have more detail. Is there another document?

Thanks,

Scott
