Record DRM

Hi guys,
As I know, Tegra tx2 DRM( direct render manager) has 2 render layer for each connector one crtc and one plane that can be blended with desired alpha.
for example " /usr/src/nvidia/graphics_demos/prebuilts/bin/egldevice/gears" has property like “-layer” that get just “0” and “1”.
As you know we use egldevice DRM window not x11 or wayland. we are in mode.
so how can we record what is shown( blended with desired alpha) in both layers in EGLdevice DRM.
Thanks so much

We don’t support the use-case. A possible solution is to encode the video planes. You can put data into NvBuffer and use hardware encoder to encode to h264 or h265 stream.
