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.
