Dispmanx window for EGL/GL on the Raspberry Pi
This is an extremely trimmed fork of videocore for opening a window to render with EGL/OpenGL ES. If you need to use more of the VC API than this crate exposes, use the original videcore crate instead.
Usage
Call bcm_host::init
, create a dispmanx::Rect
for src and dest,
create a dispmanx::VCAlpha
, and call dispmanx::create_window
which returns a window struct which can be passed to eglCreateWindowSurface.
See examples for details.
When building, make sure pkg-config can find the driver userspace libraries.
Build with the envvar PKG_CONFIG_LIBDIR
set to /opt/vc/lib/pkgconfig
, and
PKG_CONFIG_ALLOW_CROSS
set to 1
if necessary.
See pkg-config-rs for details.
For example: to build and run the example on a Raspberry Pi, run
PKG_CONFIG_LIBDIR=/opt/vc/lib/pkgconfig cargo run --example gles2
