egl_render rendering planned ?

Open rafaelSorel opened this issue 7 years ago • 3 comments

Hello,

Is it possible to add flagged video egl_rendering using amvideocapture or ion ?

Thanks,

The Mali-450 GPU does not support ARM Framebuffer Compression (AFBC). This means its not possible to process 4K@60 video using the GPU due to memory bandwidth limitations. The video output layer currently used does support AFBC and works without issue at 4K@60. Due to this, I have no plans to add EGL rendering.

Yes I perfectly get this part , I want just to experiment the 1080p@60fps using EGL, thats why I have asked for this. If you confirm that I can do it using amlcapture, with a copy to EGL image , it is ok for me ?

An example is here: https://github.com/OtherCrashOverride/CXVideoCube/commits/ce06e11f770f2e8aaabae1c81336e9cd0fdf368f

TL;DR = It can be done because it has been done, but the example is not up to date. Its meant for developer guidance only.
