# Missing WebRTC support, but ENABLE_MEDIA_STREAM/ENABLE_WEB_RTC is experimental upstream (PRIVATE OFF) and shouldn't be used yet in 2.30
# >=gst-plugins-opus-1.14.4-r1 for opusparse (required by MSE)
# TODO: gst-plugins-base[X] is only needed when build configuration ends up with GLX set, but that's a bit automagic too to fix
# Softblocking webkit-gtk-2.38:4 as we going to use webkit-2.38:4.1's WebKitDriver binary
