We have developed directshow based codec using VPU(for WEC 2013, WEC 7).

Hi, All.

We have make Video decoding filter and Video renderer filter for WEC 2013 and WEC 7.

Video decoding filter decode H.264(1080P, 60FPS) stream data using VPU.

Video renderer filter display NV12 data using Directdraw.

Video decoding and renderer filters are based Directshow.

Our codec is supported mp4, avi, mkv, wmv, mpeg, etc. files.

Also, Our codec is supported both videoc codec such as H.264, MPEG2, MPEG4 and audio codec such as MPEG1-Layer III, AAC, FLAC, Vorbis, AC3.

The following video shows the mp4 file(H.264, AAC) playback on WAD-MX6 board with i.MX6 Dual Core.

We have a quesion.

For better performance, we want to render with 3D accelerator(using OpenGL ES 2.0).

But in base WEC 2013 BSP, both OpenGL ES 2.0 library and GPU Driver are old version.

The library is slow and not supported i.MX6 Quad Plus.

we want to get new version OpenGL ES 2.0 library.

To get it, we contacted to vivante. But could not get anything.

Please let us know how to get the last version OpenGL ES 2.0 library.

Thank you.

Hi Minsung

nxp does not support WEC on i.MX6 platforms, may be recommended to

apply to third parties who support it:

Embedded Boards, Modules, Design Services, i.MX6 SOM | iWave Systems

Adeneo Embedded

Thank you for your reply.

I know that NXP does not support WEC 2013.

But OpenGL ES 2.0 Library source code is closed.

I connected third parties, but could not get anything.

If source code of OpenGL ES 2.0, I will port to WEC 2013.

I will wait for a more accurate answer.

Thanks.

gpu source codes are license protected and not available for customers.

Please apply to local marketing office if you have special reasons.

I need last version library of OpenGL ES 2.0.

I do not need the source code of OpenGL ES 2.0.

I contacted to local office, vivante and third parties.

But they told me to contact NXP.

In other words, I'm looking for an OpenGL ES 2.0 library that support i.MX6 Quad Plus on WEC 2013.

Thanks.
