*
* While "normal" mpv loads the OpenGL hardware decoding interop on demand,
* this can't be done with opengl_cb for internal technical reasons. Instead,
* make it load the interop at load time by setting the "hwdec-preload"="auto"
* option before calling mpv_opengl_cb_init_gl().
* make it load the interop at load time by setting the
* "opengl-hwdec-interop"="auto" option before calling mpv_opengl_cb_init_gl()
* ("hwdec-preload" in older mpv releases).
*
* There may be certain requirements on the OpenGL implementation:
* - Windows: ANGLE is required (although in theory GL/DX interop could be used)
* - Intel/Linux: EGL is required, and also a glMPGetNativeDisplay() callback
* must be provided (see sections below)
* - nVidia/Linux: GLX is required
* - nVidia/Linux: GLX is required (if you force "cuda", it should work on EGL
* as well, if you have recent enough drivers and the
* "hwaccel" option is set to "cuda" as well)
* - OSX: CGL is required (CGLGetCurrentContext() returning non-NULL)
*
* Once these things are setup, hardware decoding can be enabled/disabled at
