IUSE="+drm +egl +gles2 opengl wayland +X" # Keep default enabled IUSE in sync with gst-plugins-base and libva |
| 16 |
|
| 17 |
# gst-vaapi configure is based around GL platform mainly, unlike gst-plugins-bad that goes by GL API mainly; for less surprises, |
| 18 |
# we design gst-vaapi ebuild in terms of GL API as main choice as well, meaning that USE opengl and/or gles2 is required to |
| 19 |
# enable opengl support at all and choices get chained from there. |
| 20 |
# One or multiple video output are required: drm, x11, glx, egl and/or wayland; |
| 21 |
# but GL API is our main trigger, thus USE=egl should be ineffective if neither gles2 or opengl is enabled; |
| 22 |
# So "|| ( drm egl opengl wayland X )" would be wrong, because egl isn't built with USE="egl -opengl -gles2", ending up with no video outputs. |
| 23 |
# As we ensure at least one working GL output with other REQUIRED_USE, we can put gles2/opengl in REQUIRED_USE instead of egl, solving the issue. |
| 24 |
# gles2 API only supported windowing system (on linux) is EGL, so require it |
| 25 |
# opengl API only supported windowing systems (on linux) are EGL and GLX, so require one of them (glx is enabled with USE="opengl X") |

# USE flag behavior: |
| 35 |
# 'drm' enables vaapi drm support |
| 36 |
# 'egl' enables EGL platform support (but only if also 'opengl||gles2') |
| 37 |
# - 'egl' is exposed as a USE flag mainly to get EGL support instead of or in addition to GLX support with desktop GL while keeping it optional for pure GLX cases; |
| 38 |
# it's always required with USE=gles2, thus USE="gles2 opengl X" will require and build desktop GL EGL platform support as well on top of GLX, which doesn't add extra deps at that point. |
| 39 |
# 'gles2' enables GLESv2 or GLESv3 based GL API support |
| 40 |
# 'opengl' enables desktop OpenGL based GL API support |
| 41 |
# 'wayland' enables non-GL Wayland support; wayland EGL support when combined with 'egl' (but only if also 'opengl||gles2') |
| 42 |
# 'X' enables non-GL X support; GLX support when combined with 'opengl' |
| 43 |
# gst-plugins-bad still needed for codecparsers (GL libraries moved to -base); checked for 1.14 (recheck for 1.16) |
