iMX6 hardware decode issue on Android

[Bing Song]

You can refer Freescale latest Yocto release. It already implemented vpudec ! glimagesink without video frame buffer copy. Their share video buffer with absolute physical address. Will share video buffer with DMA FD in the future.

Why need replace Freescale media player with GStreamer player on Android? Do you have any special requirement?

Song Bing.

Hi,

Interresting stuff !! :) Thanks for your interrest.

I did explore eglvivsink possibility but facing problems when linking it to
android egl vivante. I can't use it as it because I have no framebuffer on
my android platform.

I get EGL/eglvivante.h header from
https://github.com/rogeriorps/gpu-samples-mx6/blob/master/lesson05/include/EGL/eglvivante.h

I'm able to build libgstimxeglvivsink.a with it setting egl platform to fb
but can't link it further.

Fb and gl symbols are missing:

../src/eglvivsink/gles2_renderer.c:725: error: undefined reference to
'glTexDirectVIVMap'
../src/eglvivsink/gles2_renderer.c:740: error: undefined reference to
'glTexDirectVIV'
../src/eglvivsink/gles2_renderer.c:772: error: undefined reference to
'glTexDirectInvalidateVIV'
../src/eglvivsink/egl_platform_fb.c:67: error: undefined reference to
'fbGetDisplayByIndex'
../src/eglvivsink/egl_platform_fb.c:148: error: undefined reference to
'fbCreateWindow'
../src/eglvivsink/egl_platform_fb.c:150: error: undefined reference to
'fbGetWindowGeometry'
../src/eglvivsink/egl_platform_fb.c:188: error: undefined reference to
'fbDestroyWindow'

I will have to link against freescale .so android egl lib. Writing fb
functions to create/destroy/get geometry of android native window does not
seems to be a big issue.

I think this is a good canditate to solve my CPU copies issue. Its looks
easyer than implementing zero copy in glimagesink.

I will look deeper to use imxeglvivsink and write android missing glue.

Thanks!

Eric
