[vlc-devel] [RFC PATCH 0/8] VAAPI direct rendering via OpenGL

[Thomas Guillem]

This set of patch is still experimental (or WIP) and follows the 2 following
patches from Petri:

https://patches.videolan.org/patch/14315/
https://patches.videolan.org/patch/14316/

As discussed during FOSDEM, we prefer avoiding creating a new vout for each
hwdec API and use the current OpenGL one (in order to benefit from 360 shaders,
and others color conversions). So we probably won't merge the va/xcb_display.c
module.

For now, direct rendering is only working with GLX, but it's not really future
proof (won't work with Wayland or EGL). See the last patches comment for EGL
issues.

I don't really like having a single OpenGL module linking with VAAPI (or maybe
others hwdec API that will come later). But I think it's better to fix that
issue for the next VLC release 4.0.

Thomas Guillem (8):
