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 multi-user.target mode.
so how can we record what is shown( blended with desired alpha) in both layers in EGLdevice DRM.
Thanks so much
Hi,
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.
