Subject: [PATCH 3/3] glamor: Fix fbo pixmap format with GL_BGRA_EXT
Red and Blue channels are swizzled in GLES path,
Fix color inverse problem with ximagesink command:
gst-launch-1.0 videotestsrc pattern=6 num-buffers=1 ! video/x-raw,format=BGRx ! videoconvert ! ximagesink display=:0 -v
This fix requires GL_EXT_texture_format_BGRA8888 extension, not applicable for upstream.
Upstream-Status: Inappropriate [embedded specific]
